# seckill（Java高并发秒杀API）
一个spring入门项目,后续将更新spring中级项目 :)
#### 所用技术点
- spring
- springMVC: MVC框架
- Tomcat: web容器
- mybatis: ORM框架
- bootstrap: css/html框架
- JQuery: JS框架
- Redis: NOSQL数据库
- MySQL: 关系型数据库
- Logback: 日志框架
- JUnit: 单元测试
- CDN: 内容分发服务器
- Procedure:数据库存储过程
- Protostuff:Google开发的基于Java语言的序列化库
- ZooKeeper:分布式应用程序协调服务
- DUBBO:分布式应用服务框架
## Java高并发秒杀系统API
本项目参考慕课网视频(版权方),并在此基础上进行了模块划分,功能添加,欢迎去官网观看!!!!
## 安装部署
#### 软件环境：
- IDEA
- MySQL
- JDK1.8或以上
- tomcat 8.0
- Redis
- Maven
#### 硬件环境(最小配置)：
- CPU：1核
- 内存：1G
#### 说明
- seckill-core：秒杀核心模块，部署tomcat启动
- seckill-api：秒杀api模块
- seckill-base：秒杀工具类模块
- seckill-web：秒杀页面模块
#### 步骤
1. 创建数据库，导入初始化脚本initDB.sql
2. 修改系统数据库连接seckill-core/src/main/resources/jdbc.properties
3. Tomcat运行
## FAQ
- Q:为什么我的maven下载依赖jar包这么慢
- A:可以自己下载maven,使用自己的Maven,修改maven安装目录下的/conf/settings.xml,在IDEA或eclipse里配置为默认的设置
```XML
<mirror>
<id>nexus-aliyun</id>
<mirrorOf>central</mirrorOf>
<name>Nexus aliyun</name>
<url>http://maven.aliyun.com/nexus/content/groups/public</url>
</mirror>
```
- Q:为什么我的数据库连不上
- A:查看一下jdbc.properties，配置url为你的数据库地址,你的数据库用户名和密码
- Q:为什控制台报Redis异常
- A:查看一下Redis服务器是否启动，没下载的建议去官网下载window或linux版
- Q:eclipse怎么导入
- A:去掉.开头的文件就可以导入!!!
