# spring-boot-mybatis-rw

基于mybatis，springboot开箱即用的读写分离插件

# Quick Start

Maven dependency

---

```

  com.github.chenlei2

  spring-boot-mybatis-rw-starter

  0.0.1.releases

```

介绍

---

此插件由以下2部分组成

- datasource：读写数据源的代理，支持一写多读，用户只需实现 com.github.chenlei2.springboot.mybatis.rw.starter.datasource.AbstractReadRoutingDataSource这个类，实现自己读数据源的负载均衡算法，默认实现com.github.chenlei2.springboot.mybatis.rw.starter.datasource.impl.RoundRobinRWDataSourceRout

- pulgin：mybatis插件实现读写路由

@Transactional(isolation = Isolation.SERIALIZABLE) 强制本事务都走写库，插件会把事务隔离级别修改为默认隔离级别

spring-boot 配置

---

```

spring.mybatis.rw.readDataSources[0].url=jdbc:MySql://localhost:3306/test?characterEncoding=UTF-8

spring.mybatis.rw.readDataSources[0].driverClassName=com.mysql.jdbc.Driver

spring.mybatis.rw.readDataSources[0].username=root

spring.mybatis.rw.readDataSources[0].password=123456

spring.mybatis.rw.readDataSources[1].url=jdbc:MySql://localhost:3306/test?characterEncoding=UTF-8

spring.mybatis.rw.readDataSources[1].driverClassName=com.mysql.jdbc.Driver

spring.mybatis.rw.readDataSources[1].username=root

spring.mybatis.rw.readDataSources[1].password=123456

spring.mybatis.rw.writeDataSource.url=jdbc:MySql://localhost:3306/chenlei?characterEncoding=UTF-8

spring.mybatis.rw.writeDataSource.driverClassName=com.mysql.jdbc.Driver

spring.mybatis.rw.writeDataSource.username=root

spring.mybatis.rw.writeDataSource.password=123456

``` 

XML配置

---

- datasource：

```

	

	    

	    

	        

	            

	            

	            

	        

	    

	

	

		

	

``` 

总结

---

只需替换数据源，其他配置不变，便实现读写分离，对代码0入侵，配置简单，非常方便老项目的迁移。
