项目的后端服务。\n\n---\n\n## 1. 环境准备 (Prerequisites)\n\n在开始之前，请确保您的开发环境中已安装以下软件：\n\n- **JDK**: 版本 `17` 或更高。请通过 `java --version` 命令确认。\n- **Maven**: 版本 `3.6` 或更高，用于构建项目。请通过 `mvn --version` 确认。\n- **Docker**: 用于运行 MySQL、Nacos 等依赖服务，以及作为代码沙箱的执行环境。\n\n---\n\n## 2. 部署核心依赖服务\n\n见 [docker部署](1.docker部署.md) 文档\n\n---\n\n## 3. 构建和运行后端微服务\n\n### 3.1. 配置微服务\n\n见以下文档：\n- [Common项目配置](2.Common项目配置.md)\n- [Gateway项目配置](3.Gateway项目配置.md)\n- [User-Service项目配置](4.User-Service项目配置.md)\n- [Problem-Service项目配置](5.Problem-Service项目配置.md)\n- [Submission-Service项目配置](6.Submission-Service项目配置.md)\n- [Sandbox-Service项目配置](7.Sandbox-service项目配置.md)\n\n### 3.2. 构建所有模块\n\n在后端父项目 `DOJ-BE` 的根目录下，使用 Maven 进行编译和打包。\n\n```sh\ncd /Users/qzj/Desktop/Development/D-OnlineJudge/DOJ-BE\nmvn clean install\n```\n\n### 3.3. 运行微服务\n\n为每个微服务打开一个单独的终端，并从 `DOJ-BE` 根目录启动它们。建议按照以下顺序启动：\n\n1. **Gateway-Service**\n ```sh\n java -Dhttp.proxySet=false -Dhttps.proxySet=false -jar gateway-service/target/gateway-service-1.0-SNAPSHOT.jar\n ```\n2. **User-Service**\n ```sh\n java -Dhttp.proxySet=false -Dhttps.proxySet=false -jar user-service/target/user-service-1.0-SNAPSHOT.jar\n ```\n3. **Problem-Service**\n ```sh\n java -Dhttp.proxySet=false -Dhttps.proxySet=false -jar problem-service/target/problem-service-1.0-SNAPSHOT.jar\n ```\n4. **Submission-Service**\n ```sh\n java -Dhttp.proxySet=false -Dhttps.proxySet=false -jar submission-service/target/submission-service-1.0-SNAPSHOT.jar\n ```\n5. **Sandbox-Service**\n ```sh\n java -Dhttp.proxySet=false -Dhttps.proxySet=false -jar sandbox-service/target/sandbox-service-1.0-SNAPSHOT.jar\n ```\n\n### 3.4. 验证服务状态\n\n- **检查 Nacos**: 再次访问 Nacos 控制台 `http://localhost:8848/nacos`，进入 “服务管理” -> “服务列表”，您应该能看到所有已启动的微服务（`gateway-service`, `user-service` 等）都处于健康状态。\n- **访问 API 文档**: 访问网关提供的聚合 API 文档 `http://localhost:8080/doc.html`，您应该能看到所有微服务的接口列表。\n\n## 4. 可观测性平台搭建\n\n### 4.1. 部署 SkyWalking (分布式追踪)\n\n项目使用 SkyWalking 进行服务间的链路追踪。我们通过一个独立的 Docker Compose 文件来部署它及其依赖的 Elasticsearch。\n\n1. **启动 SkyWalking 服务**:\n 在项目根目录下，执行以下命令：\n ```sh\n docker-compose -f docker-compose-skywalking.yml up -d\n ```\n\n2. **访问 SkyWalking UI**:\n 等待一到两分钟，让所有服务完全启动。然后，通过浏览器访问 `http://localhost:9999`。\n\n### 4.2. 部署 Prometheus + Grafana (指标监控)\n\n我们使用 Prometheus 抓取指标，Grafana 进行可视化展示。\n\n1. **启动监控服务**:\n 在项目根目录下，执行以下命令：\n ```sh\n docker-compose -f docker-compose-monitoring.yml up -d\n ```\n\n2. **访问 Grafana UI**:\n 通过浏览器访问 `http://localhost:3000` (默认用户名/密码: `admin`/`admin`)。\n\n3. **配置数据源与仪表盘**:\n 在 Grafana 中，添加 Prometheus (`http://prometheus:9090`) 作为数据源，然后即可创建或导入仪表盘来展示微服务指标。\n\n4. **导入预置仪表盘 (推荐)**:\n 为了快速开始，项目根目录下提供了一个预置的仪表盘文件 `grafana-dashboard.json`。\n - 在 Grafana 左侧菜单，点击 “+” -> “Import dashboard”。\n - 点击 “Upload JSON file”，选择项目中的 `grafana-dashboard.json` 文件。\n - 在下方的 “Prometheus” 选项中，选择您刚刚配置好的 Prometheus 数据源。\n - 点击 “Import”，即可拥有一个包含所有核心指标的监控大盘。\n\n### 4.3. 部署 Loki (日志聚合)\n\n我们使用 Loki 聚合所有微服务的日志，并由 Promtail 进行采集。\n\n1. **启动日志服务**:\n Loki 和 Promtail 的配置已包含在 `docker-compose-monitoring.yml` 中。执行以下命令即可一并启动：\n ```sh\n docker-compose -f docker-compose-monitoring.yml up -d\n ```\n\n2. **在 Grafana 中添加 Loki 数据源**:\n - 访问 Grafana (`http://localhost:3000`)。\n - 进入 \"Configuration\" -> \"Data sources\"，点击 \"Add data source\"。\n - 选择 \"Loki\"。\n - 在 URL 字段中，输入 `http://loki:3100`。\n - 点击 \"Save & test\"。\n\n3. **查询日志**:\n 添加成功后，即可在 Grafana 的 \"Explore\" 页面选择 Loki 数据源，并通过容器名称等标签来查询日志。\n\n### 4.4. 为微服务挂载 Agent (IntelliJ IDEA)\n\n为了让微服务能被 SkyWalking 追踪，需要在启动时为其挂载 Agent 探针。\n\n1. **修改运行配置**: 在 IntelliJ IDEA 中，为每一个后端微服务（`user-service`, `gateway-service` 等）的“运行/调试配置” (Run/Debug Configurations) 进行修改。\n2. **添加 VM 选项**: 找到 \"VM options\" 输入框，并添加以下两行：\n ```\n -javaagent:/path/to/your/skywalking-agent/skywalking-agent.jar\n -Dskywalking.agent.service_name=user-service\n ```\n - **注意**: \n - 将 `/path/to/your/skywalking-agent/` 替换为您本地 `skywalking-agent` 文件夹的**绝对路径**。\n - `-Dskywalking.agent.service_name` 的值需要为每个服务单独设置（如 `problem-service`, `gateway-service` 等）。\n\n3. **重启所有服务**后，即可在 SkyWalking UI 上看到服务拓扑和调用链路。\n\n---\n\n## 5. 代码沙箱 Docker 环境\n\n`sandbox-service` 依赖于预先构建好的 Docker 镜像来执行代码。请确保您已经构建了项目所需的多语言执行环境镜像。\n\n进入 `docs/7.Sandbox-service项目配置.md` 文件所在的目录，您会找到 `Dockerfile.cpp`, `Dockerfile.java`, `Dockerfile.python` 等文件。\n\n使用以下命令构建镜像：\n\n```sh\n# 构建 C++ 环境镜像\ndocker build -t code-runner-cpp -f Dockerfile.cpp .\n\n# 构建 Java 环境镜像\ndocker build -t code-runner-java -f Dockerfile.java .\n\n# 构建 Python 环境镜像\ndocker build -t code-runner-python -f Dockerfile.python .\n```\n\n确保这些镜像在 `sandbox-service` 运行的 Docker 环境中是可用的。\n\n---\n\n## 5. 自动化部署 (CI/CD)\n\n除了手动部署，本项目已配置了一套基于 GitHub Actions 的自动化 CI/CD 流水线。当代码被推送到 `main` 分支时，会自动触发以下流程：\n\n1. **并行构建**: 自动编译所有微服务，并使用各自的 `Dockerfile` 构建 Docker 镜像。\n2. **推送镜像**: 将构建好的镜像推送到 Docker Hub。\n3. **远程部署**: 通过 SSH 连接到服务器，拉取最新镜像并使用 `docker-compose` 重启服务。\n\n### 准备工作\n\n### 核心环境变量说明\n\n本项目的容器化部署高度依赖环境变量来实现配置的灵活性。以下是在 `docker-compose-service.yml` 中使用的核心变量及其作用：\n\n- **`NACOS_SERVER_ADDR`**: Nacos 服务器地址，容器环境应设为 `nacos:8848`。\n- **`SENTINEL_DASHBOARD_ADDR`**: Sentinel Dashboard 地址，容器环境应设为 `sentinel:8080`。\n- **`DOJ_DB_HOST`**: 数据库主机地址，容器环境应设为 `mysql`。\n- **`DOJ_MQ_HOST`**: RabbitMQ 主机地址，容器环境应设为 `rabbitmq`。\n- **`DOJ_REDIS_HOST`**: Redis 主机地址，容器环境应设为 `redis`。\n- **`HOST_CODE_PATH`**: (仅用于 `sandbox-service`) 宿主机上用于存放临时代码的目录的绝对路径。通过 `${PWD}/static/codes` 动态获取，用于解决 Docker-out-of-Docker 的路径挂载问题。\n- **`JAVA_OPTS`**: 用于设置 JVM 启动参数，如 `-Xms128m -Xmx256m`，以控制服务内存占用。\n\n核心配置文件位于 `.github/workflows/ci-cd.yml`。\n\n## 6. 前端部署 (Docker + Nginx)\n\n前端项目 (`DOJ-FE`) 采用业界标准的“打包 + Nginx 托管”的方式进行容器化部署。\n\n### 6.1. 环境与配置\n\n在部署前，请确保已完成以下配置，以保证前后端通信正常：\n\n1. **环境变量**: 项目通过 `.env.development` 和 `.env.production` 文件来管理不同环境的 API 地址。我们已将其统一为相对路径 `/api`。\n\n2. **Vite 代理 (仅开发环境)**: 在 `vite.config.ts` 中配置了 `server.proxy`，使得在开发模式下，所有对 `/api` 的请求都会被代理到本地运行的后端网关 (`http://localhost:8080`)。\n\n3. **Nginx 代理 (生产环境)**: 在 `DOJ-FE/nginx.conf` 文件中，配置了反向代理规则。所有 `/api` 请求会被转发到 `http://host.docker.internal:8080/`，即宿主机上运行的后端网关服务。这使得容器化的前端可以与本地运行的后端进行通信。\n\n### 6.2. 一键部署脚本\n\n为了简化部署流程，项目在 `DOJ-FE` 目录下提供了一个一键部署脚本 `run-docker.sh`。\n\n**使用方法:**\n\n1. **进入前端项目目录**:\n ```sh\n cd /Users/qzj/Desktop/Development/D-OnlineJudge/DOJ-FE\n ```\n\n2. **为脚本添加执行权限 (仅需一次)**:\n ```sh\n chmod +x run-docker.sh\n ```\n\n3. **执行一键部署**:\n ```sh\n ./run-docker.sh\n ```\n\n该脚本会自动完成以下所有工作：\n- **打包应用**: 执行 `pnpm build` 生成最新的静态文件到 `dist` 目录。\n- **构建镜像**: 执行 `docker build`，根据 `Dockerfile` 将 `dist` 目录和 `nginx.conf` 打包成一个名为 `doj-frontend` 的 Nginx 镜像。\n- **清理旧容器**: 自动停止并删除任何已存在的同名旧容器。\n- **启动新容器**: 启动一个新的容器，并将主机的 `8088` 端口映射到容器的 `80` 端口。\n\n部署成功后，即可通过浏览器访问 `http://localhost:8088` 来使用 D-OnlineJudge 系统。\n\n" }, { "path": "docs/0.re.md", "content": "### **项目：D-OnlineJudge

Structure)**\n\n后端项目 `DOJ-BE` 遵循标准的 Maven 多模块项目布局。\n\n```\nDOJ-BE/\n├── pom.xml # 父项目 POM，管理所有依赖和模块\n├── common/ # 公共模块 (工具、配置、Feign 客户端)\n│ ├── pom.xml\n│ └── src/\n├── gateway-service/ # API 网关服务\n│

Sentinel**，升级为系统的“**流量治理与安全中枢**”，为整个后端服务集群提供了强大的保护能力。\n\n- **统一入口与路由**: 所有外部请求的唯一入口，基于路径将流量精确分发至下游服务。\n- **安全屏障**: \n - **企业级认证**: 采用**长短令牌（Refresh/Access Token）机制**，通过网关层的全局过滤器（GlobalFilter）高效校验短令牌 `access_token`。\n - **服务访问控制**: 在各微服务中配置拦截器，强制要求所有请求必须包含源自网关的特定标识，杜绝了内网环境下的服务横向穿透风险。\n\n- **流量智能治理 (Sentinel)**: \n - **流量控制 (Flow Control)**: 我们为核心接口配置了精细化的 QPS（每秒查询率）限流规则。例如，为防止高频“刷题”，对“获取题目详情”接口 (`/problem/{id}`) 设置了“10次/分钟”的访问限制。这是通过将 QPS 设置为1，并配合“排队等待”的流控效果（等待超时6秒）来实现的，既能精确控制频率，又能缓冲用户的正常突发请求，体验更平滑。\n - **熔断降级 (Circuit Breaking)**: 我们为所有跨服务的调用配置了基于“慢调用比例”的熔断规则。例如，当对 `user-service` 的调用响应时间超过预设阈值（如200ms）的比例过高时，网关会自动“熔断”对此服务的新请求，在一段时间内直接返回友好错误，而不是让大量请求堆积、超时。这能有效防止单个下游服务的故障或性能下降，通过“雪崩效应”拖垮整个系统，极大地提升了系统的健壮性。\n - **动态与持久化**: 所有 Sentinel 规则都存储在 **Nacos** 中，网关服务在启动时会自动拉取，并能动态监听其变更。这使得运维人员可以在不重启服务的情况下，通过 Nacos 控制台实时调整流控和熔断策略。\n\n### 亮点二：混合消息模式：Redis任务队列与RabbitMQ事件总线\n\n为了同时满足判题任务的“高性能分发”和业务事件的“可靠广播”这两种不同需求，我们采用了一套优雅的混合消息架构，充分利用了 Redis 和 RabbitMQ 各自的优势。\n\n- **Redis List 作为任务队列**: 对于判题任务的分发，我们追求的是极致的低延迟和高吞吐。Redis 基于内存的 `LPUSH` / `BRPOP` 命令提供了完美的轻量级任务队列实现，使得 `sandbox-service` 的提交接口可以瞬时响应。\n- **RabbitMQ 作为事件总线**: 对于判题完成后的状态变更，这属于业务领域的事件。我们使用 RabbitMQ 强大的 Topic 交换机来广播这些事件（如 `submission.created`, `problem.solved`），未来任何对这些事件感兴趣的下游服务（如统计服务、徽章服务等）都可以灵活地订阅，实现了真正的事件驱动和微服务解耦。\n\n```mermaid\nsequenceDiagram\n autonumber\n participant FE as 前端\n

Problem\n```\n\n### 亮点三：企业级认证与分布式缓存中心\n\n我们引入 **Redis** 作为核心的内存数据中间件，并升级了认证体系，实现了高性能与高安全性的统一。\n\n#### 认证与刷新流程\n\n```mermaid\nsequenceDiagram\n autonumber\n participant User as 用户\n participant Frontend as 前端\n participant Gateway as 网关\n participant UserService as 用户服务\n participant Redis as Redis\n\n User->>Frontend: 输入用户名/密码登录\n Frontend->>Gateway: POST /user/login\n Gateway->>UserService: 转发登录请求\n\n activate UserService\n UserService->>UserService: 校验用户名/密码\n UserService->>UserService: 生成 access_token (JWT)\n UserService->>UserService: 生成 refresh_token (UUID)\n UserService->>Redis: 将 {refresh_token: userId} 存入 Redis (设置过期时间)\n UserService-->>Frontend: 返回 access_token 和 refresh_token\n deactivate UserService\n\n Note over Frontend: 前端将两个 token 存入持久化存储 (Pinia)\n\n loop 日常API请求\n Frontend->>Gateway: GET /problem/list (Header携带 access_token)\n activate Gateway\n Gateway->>Gateway: 校验 access_token (JWT)\n alt access_token 有效\n Gateway->>ProblemService: 转发请求 (注入 userId)\n else access_token 过期\n Gateway-->>Frontend: 返回 401 Unauthorized\n end\n deactivate Gateway\n end\n\n Note over Frontend: 收到 401 错误，触发静默刷新逻辑\n\n Frontend->>Gateway: POST /user/refresh (Header携带 refresh_token)\n Gateway->>UserService: 转发刷新请求\n\n activate UserService\n UserService->>Redis: 在 Redis 中查找 refresh_token 是否存在\n alt refresh_token 有效\n UserService->>Redis: 从

UserService\n\n Note over Frontend: 收到新 access_token，更新本地存储，并重试刚才失败的API请求\n```\n\n- **长短令牌机制**:\n - **`access_token` (JWT)**: 短时效、无状态，用于API请求，包含用户的角色权限信息，由网关进行快速验证。\n - **`refresh_token`**: 长时效、有状态，存储在 **Redis** 中。用于在`access_token`过期后，安全地换取新的令牌，实现了用户的无感续期和强制下线等高级功能。\n- **分布式高速缓存**: \n - **热点数据缓存**: 将频繁访问且不常变化的数据，如用户信息、题目详情、热门排行榜等，缓存在Redis中，大幅降低数据库的读取压力。\n - **分布式锁**: 利用Redis实现分布式锁，解决在集群环境下更新题目通过数、用户积分等场景下的并发安全问题。\n\n### 亮点四：优雅的认证与用户上下文传递\n\n在微服务架构中，如何安全、无感地将用户的身份信息（如 User ID）在服务调用链中传递，是一个核心问题。本项目采用了一套“网关注入 -> 线程内缓存 -> Feign自动填充 -> 权限校验”的优雅方案。\n\n```mermaid\nsequenceDiagram\n participant Gateway as 网关\n participant ServiceA as 微服务A (e.g., Sandbox)\n participant ServiceB as 微服务B (e.g., Problem)\n\n Gateway->>ServiceA: 1. 转发请求 (Header 中已包含 `uid`)\n \n activate ServiceA\n ServiceA->>ServiceA: 2. `IdentityInterceptor` 拦截请求\n ServiceA->>ServiceA: 3. 从 Header 读取 `uid` 并存入 `UserContext` (ThreadLocal)\n ServiceA->>ServiceB: 4. 通过

Header 中\n\n activate ServiceB\n ServiceB->>ServiceB: 7. `IdentityInterceptor` 再次拦截\n ServiceB->>ServiceB: 8. 验证 Header 中存在 `uid`，放行\n deactivate ServiceB\n```\n\n```mermaid\nsequenceDiagram\n participant Gateway as 网关\n participant ProblemService as 题目服务\n participant UserService as 用户服务\n\n Gateway->>ProblemService: 1. 转发请求 POST /problem (Header 中已包含 `uid`)\n \n activate ProblemService\n ProblemService->>ProblemService: 2. `IdentityInterceptor` 拦截请求, 将 `uid` 存入 `UserContext`\n ProblemService->>ProblemService: 3. `AdminCheckInterceptor` 拦截请求, 发现 `@AdminRequired` 注解\n ProblemService->>UserService: 4. 通过 Feign `UserClient` 调用 `getUserById(uid)`\n activate UserService\n UserService-->>ProblemService: 5. 返回用户信息 (包含 `role`)\n deactivate UserService\n ProblemService->>ProblemService: 6. 校验 `role` 是否为 'admin', 校验通过\n ProblemService->>ProblemService: 7. 执行 Controller 业务逻辑\n ProblemService-->>Gateway: 8. 返回响应\n deactivate ProblemService\n```\n\n- **网关层统一注入**: 所有外部请求经网关认证后，用户的 `userId` 被解析并放入请求头，作为身份标识的唯一来源。\n- **线程内上下文 (`ThreadLocal`)**: 每个业务微服务都配置了一个 `IdentityInterceptor`。它在处理每个请求的开始，从请求头中读取 `userId` 并存入一个 `ThreadLocal` 变量 (`UserContext`) 中。这使得在当前请求的处理线程中，任何地方的业务代码都可以方便地通过 `UserContext.getCurrentUser()` 获取当前用户ID，而无需在方法参数中层层传递。\n- **Feign 自动填充**: 为了解决服务间调用时 `ThreadLocal` 信息丢失的问题，我们配置了一个全局的 Feign `RequestInterceptor`。它会在每一次 Feign 调用发起前，自动从 `UserContext` 中获取 `userId`，并将其添加到新的 HTTP 请求头中。这确保了用户身份在整个微服务调用链中能够无缝、安全地传递下去。\n\n#### 扩展：管理员权限校验\n\n基于以上用户上下文传递机制，我们构建了一套非侵入式的管理员权限校验方案。\n\n- **`@AdminRequired` 注解**: 我们创建了一个自定义注解，只需将其标记在任何需要管理员权限的 Controller 方法上即可。\n- **`AdminCheckInterceptor`**: 我们创建了第二个拦截器，它会在 `IdentityInterceptor` 之后执行。如果检测到方法上的 `@AdminRequired` 注解，它就会通过 `UserContext` 获取用户ID，然后通过 Feign 客户端 `UserClient` 回调 `user-service` 获取该用户的角色。如果角色不是 `admin`，则直接抛出 `ForbiddenException`，请求被终止并返回 403 错误。\n- **依赖注入与启动**: 通过在每个微服务的主启动类上使用 `@Import({..., AdminCheckInterceptor.class})`，我们确保了该拦截器作为一个 Bean 被 Spring 容器管理，从而解决了因 Feign 客户端初始化而可能导致的循环依赖问题。\n\n### 亮点五：全局 WebSocket 实时通知\n\n为了在异步判题架构下，向用户提供优雅、无干扰的实时结果反馈，我们构建了一套全局的 WebSocket 通知系统，取代了需要用户停留在当前页面的传统方案。\n\n```mermaid\nsequenceDiagram\n autonumber\n participant FE as 前端\n participant Submission as 提交服务\n participant Redis as Redis Pub/Sub (或 RabbitMQ)\n\n FE->>Submission: 1. 提交代码后，拿到 submissionId\n FE->>Submission: 2. 建立 WebSocket 连接\n activate Submission\n Submission->>Submission: 3. 存储 Session，并与 submissionId 关联\n deactivate Submission\n\n Note right of Submission: ... 判题流程在后台异步进行 ...\n\n activate Submission\n Submission->>Redis: 4. 监听器收到判题结果消息\n Submission->>Submission: 5. 根据 submissionId 查找对应的 Session\n Submission-->>FE: 6. 通过 WebSocket 主动推送结果\n deactivate Submission\n\n FE->>FE: 7. 收到消息，更新UI（弹出通知）\n```\n\n- **全局服务化**: 我们将 WebSocket 的所有连接管理、消息监听和处理逻辑，都封装在一个独立的、全局可用的服务 (`src/utils/websocket.ts`) 中。该服务在应用根组件 (`App.vue`) 挂载时被初始化，确保了其生命周期与整个应用保持一致。\n\n- **按需订阅**: 用户在提交代码后，前端会调用 `useWebSocket().subscribeToSubmission(submissionId)` 方法。该方法会通过已建立的全局 WebSocket 连接，向后端发送一条“订阅”消息，将当前会话与本次提交的 `submissionId` 关联起来。\n\n- **非阻塞式富文本通知**: 当后端判题完成，并通过 WebSocket 推送结果时，前端的全局监听器会捕获到该消息。它并不会粗暴地打断用户的当前操作，而是调用 Element Plus 的 `ElNotification` 组件，在屏幕的右下角弹出一个内容丰富的通知卡片。我们利用 Vue 的 `h` 函数（渲染函数）来动态构建通知的 `message`，使其可以包含状态、耗时、内存、错误信息等复杂的 HTML 结构。\n\n- **可交互与自动关闭**: 该通知卡片在显示一段时间后会自动消失，用户也可以点击它，页面会自动跳转到对应的提交详情页，实现了从“收到结果”到“查看详情”的无缝体验。\n\n### 亮点六：高性能三级缓存架构 (L1+L2+DB)\n\n对于“题目详情”这类访问频率极高、但内容不常变更的“热点数据”，我们设计并实现了一套“本地缓存 + 分布式缓存 + 数据库”的三级缓存架构，最大限度地降低了数据库压力，将查询性能提升至极致。\n\n```mermaid\ngraph TD\n subgraph \"读请求 (Read Flow)\"\n direction LR\n Read_A[API Request: GET /problem/1] --> Read_B{Problem Service 1};\n Read_B -- 1. 查 L1 --> Read_C[L1: Caffeine];\n Read_C -- Miss --> Read_D{2. 查 L2};\n Read_D --> Read_E[L2: Redis];\n Read_E -- Miss --> Read_F{3. 查 L3};\n Read_F --> Read_G[L3: MySQL];\n Read_G -- 数据回填 --> Read_E;\n Read_E

Write_E fill:#f9f,stroke:#333,stroke-width:2px\n style Write_H fill:#ff9,stroke:#333,stroke-width:2px\n```\n\n- **L1 本地缓存 (Caffeine)**: 速度最快的内存级缓存。对于短时间内对同一个题目的重复请求，将直接在纳秒级从内存返回，无需任何网络开销。\n- **L2 分布式缓存 (Redis)**: 速度很快的集中式缓存。当 L1 缓存未命中时（例如，服务实例首次访问该数据），会查询 Redis。这避免了对数据库的直接访问，并且缓存结果由所有 `problem-service` 实例共享。\n- **L3 数据源 (MySQL)**: 最终的数据保障，只有当 L1 和 L2 缓存都未命中时，才会查询数据库。\n\n#### 核心查询流程与场景\n\n1. **L1 命中 (理想情况)**: 请求直接由本地内存返回，性能最佳。\n2. **L2 命中 (跨实例协同)**: L1 未命中，但从 Redis 中获取到数据。数据会**回填**到 L1 缓存中，以便下一次访问能直接命中 L1。\n3. **L1 & L2 均失效 (缓存穿透/冷启动)**: 缓存中无数据，查询将穿透到数据库。查询成功后，数据会**依次写回**到 L2 (Redis) 和 L1 (Caffeine) 中，完成缓存的预热。\n\n#### 缓存一致性保证\n\n当题目信息被更新或删除时，为了保证数据一致性，我们采用“**L2 缓存淘汰 + MQ 广播**”的策略：\n1. 服务实例在完成数据库操作后，立即删除 Redis 中的 L2 缓存。\n2. 同时，向 RabbitMQ 的一个 Fanout 交换机（广播模式）发送一条“缓存失效”消息。\n3. 所有 `problem-service` 实例（包括操作者自身）都会监听到这条消息，并各自删除自己内存中的 L1 缓存。这确保了所有实例的本地缓存在短时间内都能达到最终一致性。\n\n### 亮点七：全链路可观测性体系 (The Three Pillars)\n\n在复杂的微服务环境中，快速定位问题和分析性能瓶颈是巨大的挑战。为此，我们构建了覆盖“日志、追踪、监控”三大黄金指标的全链路可观测性体系，让系统的内部状态不再是“黑盒”。\n\n| 支柱 | 技术选型 | 核心作用 (回答的问题) |\n| :--- | :--- | :--- |\n| **日志 (Logs)** | **ELK / Loki** | **“发生了什么？”** - 提供离散的、具体的事件记录。 |\n| **指标 (Metrics)** | **Prometheus + Grafana** | - **立体化监控与告警 (Prometheus + Grafana)**|\n| **追踪 (Traces)** | **Apache SkyWalking** | **“请求经历了什么？”** - 串联单次请求在多个服务间的完整调用路径和耗时。 |\n\n- **日志聚合 (Loki)**:\n - **日志采集 (`Promtail`)**: 我们部署了 Promtail 作为日志采集代理。它通过 Docker 服务发现，能自动找到所有正在运行的微服务容器，并抓取它们的标准输出（stdout）日志。\n - **日志存储与查询 (`Loki`)**: Promtail 将采集到的日志流打上标签（如 `container=\"/user-service\"`）后，发送给 Loki 进行存储。Loki 只对标签进行索引，而不是对日志内容进行全文索引，这使得它极其轻量且存储成本极低。\n - **查询与关联 (`Grafana`)**: 在 Grafana 中，我们可以使用 LogQL（一种类似 PromQL 的查询语言）来高效地搜索和过滤日志，例如 `{container=\"/problem-service\"} |= \"ERROR\"`。更强大的是，我们可以通过 SkyWalking 的 TraceID，在 Grafana 中一键从 Trace 视图跳转到相关的日志，实现链路与日志的无缝关联，极大提升了分布式系统的排障效率。\n\n- **指标暴露 (`Actuator`)**: 每个微服务都集成了 Spring Boot Actuator 和 Micrometer，通过 `/actuator/prometheus` 端点，以 Prometheus 要求的格式，暴露出海量的、涵盖 JVM、HTTP 请求、连接池等多个维度的核心指标。\n- **指标采集 (`Prometheus`)**: 我们部署了 Prometheus 服务，并配置其通过 Nacos 进行服务发现。这使得 Prometheus 能够自动找到所有在线的微服务实例，并定期从它们的指标端点“抓取”(Scrape) 数据，存入其内置的时序数据库中。\n- **数据可视化 (`Grafana`)**: 我们使用 Grafana 作为统一的可视化平台。通过配置 Prometheus 为数据源，我们可以使用强大的 PromQL 查询语言（例如，`sum(rate(http_server_requests_seconds_count{job=\"doj-services\"}[1m])) by (service)`）来聚合和分析指标，并创建包含折线图、仪表盘、告警规则的专业监控大盘。\n\n#### SkyWalking：分布式系统的“GPS导航”\n\n在三大支柱中，SkyWalking 扮演着不可或缺的“GPS导航”角色。当一个请求变慢或出错时，日志只能告诉我们某个服务报错了，监控指标只能告诉我们某个服务的CPU升高了，但只有**链路追踪**能清晰地告诉我们：\n\n- 这个请求从网关开始，依次经过了哪些服务？\n- 在每个服务内部，它调用了哪些方法、访问了哪个数据库？\n- 整个调用链条中，到底是**哪一环**花费了最长的时间，或者**哪一环**最先抛出了异常？\n\n**实现原理**: 我们通过 `-javaagent` 的方式，为每个微服务无侵入式地挂载了 SkyWalking 的探针。该探针会自动拦截所有进出的 HTTP 请求、JDBC 调用、MQ 消息等，并生成和传递一个全局唯一的 `TraceID`，最终将整条调用链的数据上报给 SkyWalking OAP 服务器进行分析和存储。\n\n#### 实际应用场景与查询指南\n\n**场景**: 用户反馈“提交代码后，页面卡了很久才显示结果”。\n\n**如何使用 SkyWalking 排查？**\n\n1. **定位慢请求**: 打开 SkyWalking UI (`http://localhost:9999`)，进入“追踪”页面。通过服务名称 (`gateway-service`)、接口路径 (`/submission/create`) 或设置最小耗时，筛选出那些响应缓慢的请求记录。\n\n2. **分析链路拓扑**: 点击一条慢请求的追踪记录，您会看到一个清晰的**火焰图或列表**，它展示了该请求从 `gateway-service` 开始，到 `submission-service`，再到 `sandbox-service` 的完整调用过程。\n\n ```\n gateway-service (2010ms)\n └── submission-service (2005ms)\n ├── (DB) INSERT ... (5ms)\n ├── (Redis) LPUSH ... (1ms)\n └── (Feign) POST /sandbox/validate (2000ms) <-- 发现瓶颈！\n └── sandbox-service (1998ms)\n └── ...\n ```\n\n3. **发现根因**: 从上图可以一目了然地发现，整个请求的耗时主要集中在 `submission-service` 对 `sandbox-service` 的 Feign 调用上。这立刻将我们的排查范围缩小到了 `sandbox-service` 内部，而不是去怀疑数据库或 Redis。这正是链路追踪的巨大价值所在。\n\n\n### 亮点八：自动化CI/CD流水线 (GitHub Actions)\n\n为了实现快速、可靠、一致的软件交付，我们基于 GitHub Actions 构建了一套完整的自动化 CI/CD (持续集成/持续部署) 流水线。开发者只需将代码推送到 `main` 分支，后续的测试、构建、打包、推送镜像、服务器部署等所有繁琐的流程都将自动完成。\n\n- **并行构建 (`Matrix Strategy`)**: 流水线利用 GitHub Actions 的 `strategy.matrix` 特性，为每一个微服务（`user-service`, `problem-service` 等）创建一个独立的构建任务。这些任务在云端并行执行，极大地缩短了所有服务的总构建时间。\n\n- **优化的多阶段构建 (`Dockerfile`)**: 我们为每个微服务都编写了优化的多阶段 `Dockerfile`。在“构建阶段”，使用包含完整 Maven 环境的镜像来编译代码和下载依赖；在“运行阶段”，仅将编译好的 `.jar` 文件复制到一个轻量的 JRE 镜像中。这使得最终生成的生产镜像体积最小化，并能充分利用 Docker 的构建缓存机制，提升后续构建的速度。\n\n- **职责分离的 Jobs (`build-and-push` & `deploy`)**:\n 1. **`build-and-push` Job**: 负责编译所有代码，构建所有微服务的 Docker 镜像，并将其推送到 Docker Hub 镜像仓库进行统一的版本管理。\n 2. **`deploy` Job**: 该任务依赖于 `build-and-push` 的成功。它会通过 SSH 安全地连接到生产服务器，执行预设的部署脚本，自动拉取最新的镜像并以 `docker-compose` 的方式重启所有服务，完成部署的“最后一公里”。\n\n通过这套流水线，我们实现了从“代码提交”到“服务上线”的全流程自动化，确保了每次部署都是可重复、可预测和高度可靠的。\n\n### 亮点九：生产级的容器化部署实践\n\n将一个复杂的微服务应用正确地部署到容器中，会遇到一系列经典的网络与文件系统挑战。本项目通过优雅的工程实践，解决了两大核心难题，确保了部署的健壮性和可移植性。\n\n- **优雅的 Nginx 服务发现与路径重写**: \n - **问题**: 在 Docker 环境中，当后端服务（如网关）重启并获得新 IP 时，Nginx 因 DNS 缓存会连接到旧的、已失效的 IP，导致 `Connection Refused`。同时，前端的 `/api` 路径前缀也需要被正确剥离。\n - **解决方案**: 我们采用了 `upstream` + `resolver` + `rewrite` 的黄金组合。通过 `upstream` 块定义服务池，并利用 `resolver` 指令强制 Nginx 动态解析其中的域名，彻底解决了 DNS 缓存问题。同时，使用 `rewrite` 指令清晰地处理路径重写，将职责完美分离，保证了配置的健壮与可读性。\n\n- **轻量级的 Docker-out-of-Docker 判题沙箱**:\n - **目标**: `sandbox-service`（判题服务）自身运行在容器中，但它需要具备动态创建和管理其他“一次性”判题容器的能力。\n - **核心实现**: 我们采用了业界标准的 “Docker-out-of-Docker” 模式，而非在容器内再嵌套一个完整 Docker 环境的 “Docker-in-Docker” 重模式。其实现包含两个关键点：\n 1. **共享通信套接字 (`docker.sock`)**: 我们通过 `volumes` 将宿主机的 Unix Socket 文件 `/var/run/docker.sock` 挂载到 `sandbox-service` 容器内部。这个 `sock` 文件是本地 Docker 客户端与 Docker 守护进程之间进行通信的 IPC 通道。通过共享它，我们巧妙地让容器内的进程能够直接与宿主机上的 Docker 守护进程对话。\n 2. **安装 Docker 客户端**: 我们在 `sandbox-service` 的 `Dockerfile` 中，通过 `apt-get` 安装了 `docker.io` 包。这为容器提供了 `docker` 命令行客户端。当服务在代码中执行 `docker run` 命令时，这个客户端就会通过挂载进来的 `docker.sock` 文件，将指令发送给宿主机的守护进程去执行，从而实现了“在容器内编排和管理宿主机上的其他容器”这一强大功能。\n\n### 亮点十：高性能全文检索 (Elasticsearch)\n\n为了提供毫秒级的题目搜索体验并支持复杂的文本查询，我们引入了 Elasticsearch 作为项目核心的搜索引擎，彻底取代了传统关系型数据库在全文检索场景下的性能瓶颈。\n\n- **技术选型与动机**: 传统的 `MySQL LIKE '%keyword%'` 查询无法利用索引，在数据量增大时性能会急剧下降，且不支持分词、相关性排序等高级功能。Elasticsearch 作为专业的搜索引擎，通过其核心的**倒排索引**机制，能提供近乎实时的搜索响应。\n\n- **双写同步架构**: 我们采用了经典的“双写”模式来保证 MySQL 和 Elasticsearch 之间的数据一致性。在 `problem-service` 中，任何对题目数据的增、删、改操作，都会在完成对主数据源 MySQL 的操作后，**同步地**对 Elasticsearch 中的对应文档执行相同的操作。这确保了两个数据源之间的准实时同步。\n\n- **IK 中文分词集成**: 为了实现精准的中文内容搜索，我们构建了集成了 **IK Analyzer** 分词插件的自定义 Elasticsearch 镜像。在 `ProblemDocument` 实体中，我们通过 `@Field` 注解为题目标题、描述等文本字段指定了 `ik_max_word`（用于索引）和 `ik_smart`（用于搜索）分词器，实现了对中文的智能切分和检索。\n\n- **动态搜索策略**: 在 `ProblemServiceImpl` 中，我们实现了一套优雅的动态搜索策略。系统会根据用户的查询条件（`needElasticsearchSearch` 方法）来智能判断：如果用户输入了题目名称、标签等需要进行全文检索的关键词，则调用 `searchByElasticsearch` 方法，利用 ES 的强大能力；如果只是简单的精确条件查询，则回退到 `searchByDatabase` 方法，直接查询 MySQL，从而为不同场景选择了最优的查询路径。\n\n- **数据一致性保障**: 我们在 `ProblemController` 中提供了一个手动的 `/syncProblemToEs` 接口，可以随时触发全量数据从 MySQL 到 Elasticsearch 的同步。这个生产级的管理功能，为数据初始化和在极端情况下的数据不一致问题提供了一个可靠的最终修复手段。\n\n---\n\n## 附录：关键技术与设计决策\n\n### 1. 全局统一异常处理\n\n为了避免在每个 Controller 方法中都使用 `try-catch` 来处理异常，并向前端返回统一、规范的错误格式，项目采用了 Spring 的全局异常处理机制。\n\n- **实现**: 通过创建一个带有 `@RestControllerAdvice` 注解的类，并为不同类型的异常（如我们自定义的 `BadRequestException`, `UnauthorizedException`，以及通用的 `Exception`）编写被 `@ExceptionHandler` 注解标记的方法。\n- **优势**: 所有的业务异常都会被这个切面捕获，并被统一包装成 JSON 格式返回给前端。这极大地简化了业务代码，并保证了 API 错误响应的一致性。\n\n### 2. 双配置文件启动模型 (`bootstrap` vs `application`)\n\n在 Spring Cloud 环境中，我们为每个微服务都配置了 `bootstrap.yaml` 和 `application.yaml` 两个文件，它们在应用启动时有不同的加载时机和用途。\n\n- **`bootstrap.yaml` (引导上下文)**:\n - **加载时机**: **优先于** `application.yaml` 加载。\n - **核心用途**: 主要用于存放那些需要**引导应用、发现配置中心**的配置。在本项目中，它只存放两项最关键的信息：\n 1. `spring.application.name`: 应用的名称，用于服务注册和配置拉取。\n 2. `spring.cloud.nacos.server-addr`: Nacos 服务器的地址。\n - **工作流程**: Spring Cloud 应用启动时，会先创建一个“引导上下文”，加载 `bootstrap.yaml`。通过这里面的配置，它知道了自己是谁、要去哪里找配置中心。然后，它会去 Nacos 拉取所有共享和私有的配置。\n\n- **`application.yaml` (应用上下文)**:\n - **加载时机**: 在 `bootstrap` 阶段**之后**加载。\n - **核心用途**: 用于存放应用的**常规业务配置**，例如服务器端口 (`server.port`)、数据库地址、Swagger 扫描路径等。这些配置的值可以被 Nacos 中的同名配置所覆盖。\n\n通过这种分离，我们确保了应用能够先找到“大本营”（Nacos），然后再从“大本营”获取详细的“作战计划”（业务配置），流程清晰且可靠。\n" }, { "path":

nacos/nacos-server:v2.5.1-slim\n```\n\n## Redis\n\n为了支持长短令牌认证和分布式缓存，项目需要 Redis 服务。\n\n1. **创建本地目录和配置文件**\n\n ```sh\n # 创建用于挂载数据和配置的目录\n mkdir -p redis/data\n # 创建一个基础的配置文件\n touch redis/redis.conf\n ```\n 在 `redis/redis.conf` 中可以添加自定义配置，例如 `bind 0.0.0.0`。\n\n2. **运行 Redis 容器**\n\n ```sh\n docker run -d \\\n --name redis \\\n -p 6379:6379 \\\n -v ${PWD}/redis/data:/data \\\n -v ${PWD}/redis/redis.conf:/usr/local/etc/redis/redis.conf \\\n --network doj \\\n redis:alpine redis-server /usr/local/etc/redis/redis.conf\n ```\n\n **命令解释**:\n * `redis:alpine`: 使用基于 Alpine Linux 的轻量级 Redis 镜像。\n * `-v ${PWD}/redis/data:/data`: 将主机当前目录下的 `redis/data` 文件夹挂载到容器内的 `/data` 目录，用于持久化存储 Redis 数据。\n * `-v ${PWD}/redis/redis.conf:/usr/local/etc/redis/redis.conf`: 将我们本地的配置文件挂载到容器内对应的位置。\n * `redis-server /usr/local/etc/redis/redis.conf`: 容器启动时，使用我们指定的配置文件来启动 Redis 服务。\n\n## RabbitMQ (消息队列)\n\n为了实现服务间的异步通信和解耦（例如，判题结果的更新），项目引入了 RabbitMQ。\n\n```sh\ndocker run -d \\\n --name rabbitmq \\\n -p 5672:5672 \\\n -p 15672:15672 \\\n --hostname my-rabbit \\\n --network doj \\\n rabbitmq:3-management\n```\n\n**命令解释**:\n* `rabbitmq:3-management`: 使用包含 Web 管理界面的官方镜像。\n* `-p 5672:5672`: 映射 AMQP 协议端口，供后端服务连接。\n* `-p 15672:15672`: 映射 Web 管理后台端口。您可以通过 `http://localhost:15672` 访问它（默认用户名/密码: `guest`/`guest`）。\n\n## Elasticsearch (ES) 和 Kibana\n\nElasticsearch 作为核心的搜索引擎，Kibana 提供数据可视化界面。由于我们需要中文分词功能，因此需要构建一个包含 IK 分词插件的自定义 Elasticsearch 镜像。\n\n1. **创建数据目录**:\n ```sh\n mkdir -p ./elasticsearch/data\n ```\n\n2. **构建带 IK 分词器的 Elasticsearch 镜像**:\n 首先，在项目根目录下创建一个 `Dockerfile` 文件:\n \n ```dockerfile\n # 使用官方 Elasticsearch 7.17.6 作为基础镜像\n FROM elasticsearch:7.17.6\n \n # 安装 IK 分词器插件（指定版本一致）\n RUN bin/elasticsearch-plugin install --batch https://release.infinilabs.com/analysis-ik/stable/elasticsearch-analysis-ik-7.17.6.zip\n \n # 关闭安全认证 + 启动为单节点\n ENV discovery.type=single-node\n ENV xpack.security.enabled=false\n ENV xpack.ml.enabled=false\n ENV xpack.watcher.enabled=false\n ENV xpack.license.self_generated.type=basic\n \n # 暴露端口\n EXPOSE 9200 9300\n \n # 保持默认的 Elasticsearch 启动命令\n ```\n \n 然后，在包含此 `Dockerfile` 的目录下执行构建命令：\n ```sh\n docker build -t elasticsearch-with-ik:7.17.6 .\n ```\n \n3. **启动 Elasticsearch (使用自定义镜像)**:\n ```sh\n docker run -d --name elasticsearch \\\n -p 9200:9200 -p 9300:9300 \\\n --memory=\"1g\" \\\n -v $(pwd)/elasticsearch/data:/usr/share/elasticsearch/data \\\n --network doj \\\n elasticsearch-with-ik:7.17.6\n ```\n - `--memory=1g`: 限制 ES 内存使用，避免 OOM。\n \n4. **启动 Kibana**:\n ```sh\n docker run -d --name kibana -p 5601:5601 \\\n -e \"ELASTICSEARCH_HOSTS=http://elasticsearch:9200\" \\\n --network doj \\\n kibana:7.17.6\n ```\n - `ELASTICSEARCH_HOSTS`: 指向 Elasticsearch 服务名和端口。\n\n## Sentinel (流量治理)\n\n项目使用 Sentinel 进行流量控制和熔断降级。\n\n```sh\ndocker run -d \\\n --name sentinel \\\n -p 8858:8858 \\\n --network doj \\\n bladex/sentinel-dashboard\n```\n\n**注意**: Sentinel Dashboard 默认端口为 `8080`，与我们的网关冲突。因此，这里将其映射到主机的 `8858` 端口。\n\n部署成功后，访问 `http://localhost:8858` 进入管理后台 (默认用户名/密码: `sentinel`/`sentinel`)。\n\n## 配置写入\n\n然后按照上面的配置依次修改每个微服务项目中的配置文件\n\n第一个：application.yaml\n\n```yaml\nserver:\n port: ${doj.port.user-service}\ndoj:\n db:\n host: 127.0.0.1\n name: doj_user\n user: root\n pwd: 123\n swagger:\n

配置\n\n为了实现流量治理，网关集成了 Sentinel，并将规则持久化到 Nacos。\n\n### `application.yaml` 配置\n\n```yaml\nspring:\n cloud:\n sentinel:\n transport:\n dashboard: localhost:8858 # 指向 Sentinel 控制台地址\n datasource:\n #

${spring.cloud.nacos.server-addr}\n data-id: gateway-sentinel-degrade-rules\n rule-type: degrade\n # ...\n```\n\n- **`transport.dashboard`**: 配置 Sentinel 控制台的地址和端口。\n- **`datasource`**: 配置动态规则的数据源。我们配置了两个 Nacos 数据源，分别用于加载**流控规则** (`flow`) 和**熔断降级规则** (`degrade`)。\n\n### Nacos 中的规则示例\n\n- **`gateway-sentinel-rules` (流控)**: 用于配置 QPS 限制等规则。\n- **`gateway-sentinel-degrade-rules` (熔断)**: 用于配置慢调用、异常比例等熔断策略。\n\n通过这种方式，所有流量治理规则都实现了集中化、动态化和持久化管理。" }, { "path": "docs/4.User-service项目配置.md", "content": "## 建库建表\n\n建库建表语句请参考 `docs/SQL/user.sql` 文件。\n\n>

"docs/7.Sandbox-service项目配置.md", "content": "# Sandbox-Service: 异步判题引擎\n\n`sandbox-service` 是 D-OnlineJudge 的核心计算单元，它不再作为传统的 HTTP 服务存在，而是被设计成一个高性能、可水平扩展的**异步任务处理引擎**。\n\n---\n\n## 1. 架构角色\n\n`sandbox-service` 在新的架构中扮演两个角色：\n\n1. **HTTP 接口提供者 (用于即时运行)**: 它保留了 `/code` 和 `/problem` 两个端点，用于处理需要立即返回结果的临时代码运行请求。这部分逻辑通过 `@Async` 注解在独立的线程池中执行，以避免阻塞 API 线程。\n\n2. **分布式任务消费者 (用于提交验证)**: 这是它的核心职责。服务在启动后，会创建多个后台 **Worker 线程**，持续地从 Redis 的 `judging:queue` 任务队列中拉取判题任务并执行。\n\n---\n\n## 2. 核心工作流程 (异步验证)\n\n```mermaid\ngraph TD\n A[Controller] -- 1. /validate 请求 --> B{构造 JudgingTask};\n B -- 2. 推入 Redis 队列 --> C[(Redis List: judging:queue)];\n \n subgraph \"后台 Worker 线程池\"\n D[Worker 1] -- 3. 阻塞式拉取 --> C;\n E[Worker 2] -- 3. 阻塞式拉取 --> C;\n F[Worker N] -- 3. 阻塞式拉取 --> C;\n end\n\n D -- 4. 执行判题 --> G{Docker 容器};\n G -- 5. 返回结果 --> D;\n D -- 6. 发布结果到 MQ --> H[(RabbitMQ: doj.topic)];\n```\n\n1. **任务投递**: `SandboxController` 的 `/validate` 接口接收到请求后，仅负责创建 `Submission` 记录并获取 `submissionId`，然后将包含所有判题信息的 `JudgingTask` 对象推入 Redis 列表，并立即返回 `submissionId`。\n2. **任务消费**: `JudgingWorker` 类在应用启动时，会根据配置（`doj.sandbox.worker-threads`）创建多个后台线程。每个线程都通过 `BRPOP` 命令阻塞式地等待任务队列。\n3. **任务执行**: Worker 线程一旦获取到任务，就会调用同步的 `JudgingServiceImpl` 来执行完整的判题逻辑，包括创建临时文件、调用 Docker、解析结果等。\n4. **结果广播**: 判题完成后，`JudgingServiceImpl` 会将包含 `submissionId` 和判题结果的消息，通过 `RabbitTemplate` 发送到 `doj.topic` 交换机，路由键为 `judging.result`。\n\n---\n\n## 3. 优势\n\n- **高吞吐量**: 提交接口（`/validate`）的响应时间被降至最低，因为它只执行一次远程调用和一次 Redis `LPUSH` 操作。\n- **可扩展性**: 当判题任务积压时，只需水平扩展 `sandbox-service` 的实例数量，新的实例会自动加入到消费者的行列中，共同处理任务，判题能力可以线性增长。\n- **高可用性**: 即使所有 `sandbox-service` 实例都宕机，未处理的判题任务依然安全地存储在 Redis 队列中，等待服务恢复后继续执行。" }, { "path": "docs/SQL/doj_problem.sql", "content": "/*\n Navicat Premium
