## What is MyBatis-Plus? MyBatis-Plus is a powerful and enhanced toolkit of MyBatis for simplifying development. It provides efficient, and out-of-the-box features (such as code generation, conditional query builders, pagination plugins...), effectively saving development time ## Links - [Documentation](https://baomidou.com) - [Code Generator](https://github.com/baomidou/generator) - [Samples](https://github.com/baomidou/mybatis-plus-samples) - [Showcase](https://github.com/baomidou/awesome-mybatis-plus) - [企业版 Mybatis-Mate 高级特性](https://gitee.com/baomidou/mybatis-mate-examples) ## Features - Fully compatible with MyBatis - Auto configuration on startup - Out-of-the-box interfaces for operate database - Powerful and flexible where condition wrapper - Multiple strategy to generate primary key - Lambda-style API - Almighty and highly customizable code generator - Automatic paging operation - SQL Inject defense - Support active record - Support pluggable custom interface - Build-in many useful extensions ## Getting started - Add MyBatis-Plus dependency - Latest Version: [![Maven Central](https://img.shields.io/maven-central/v/com.baomidou/mybatis-plus.svg)](https://search.maven.org/search?q=g:com.baomidou%20a:mybatis-*) - Maven: - SpringBoot2 ```xml com.baomidou mybatis-plus-boot-starter Latest Version ``` - SpringBoot3 ```xml com.baomidou mybatis-plus-spring-boot3-starter Latest Version ``` - SpringBoot4 `^3.5.13` ```xml com.baomidou mybatis-plus-spring-boot4-starter Latest Version ``` - `^3.5.9` may need additional citations - jdk11+ ```xml com.baomidou mybatis-plus-jsqlparser Latest Version ``` - jdk8 ```xml com.baomidou mybatis-plus-jsqlparser-4.9 Latest Version ``` - Gradle - SpringBoot2 ```groovy compile group: 'com.baomidou', name: 'mybatis-plus-boot-starter', version: 'Latest Version' ``` - SpringBoot3 ```groovy compile group: 'com.baomidou', name: 'mybatis-plus-spring-boot3-starter', version: 'Latest Version' ``` - Modify mapper file extends BaseMapper interface ```java public interface UserMapper extends BaseMapper { } ``` - Use it ``` java List userList = userMapper.selectList( new QueryWrapper() .lambda() .ge(User::getAge, 18) ); ``` MyBatis-Plus will execute the following SQL ```sql SELECT * FROM user WHERE age >= 18 ``` > This showcase is just a small part of MyBatis-Plus features.

    试验性功能,解决mybatis堆内存过大的问题(看后期mybatis官方会不会解决堆内存占用问题)

    *

    例如: {@code create_time=#{createTime}}等公共字段

    *

    * 解决方案: 将生成的xml节点值写入字符串常量池,减少后面重复字符串导致的问题 *

  • * 方案一: 缓存一些特定的mybatis-plus生成的占位符与表达式和项目公共字段(改动有点多,需要增加一些特定xml属性来标记是mybatis-plus生成的节点,减少堆内存较少) *
    • *
  • * 方案二: 直接将节点内容intern写入至字符串常量池(改动少,减少堆内存多,弊端可能会将一些无重复的字符串写入至常量池) *
    • *
  • * 方案三: 模拟字符串常量池,减少重复字符串写入至堆内存(代码相对来说不好看点) *

  • 事务需要自行控制

  • 关于事务必须执行到flushStatements才具有意义{@link org.apache.ibatis.executor.BatchExecutor#doFlushStatements(boolean)} *
  • 返回值为批处理结果,如果对返回值比较关心的可接收判断处理
    • *
  • saveOrUpdate尽量少用把,保持批处理为简单的插入或更新
    • *
  • 关于saveOrUpdate中的sqlSession,如果执行了select操作的话,BatchExecutor都会触发一次flushStatements,为了保证结果集,故使用包装了部分sqlSession查询操作

  • autoCommit参数,在spring下使用的是{@link org.mybatis.spring.transaction.SpringManagedTransaction},控制无效,只能通过datasource控制(建议不要修改),单独使用mybatis下{@link org.apache.ibatis.transaction.jdbc.JdbcTransaction}是可用的
