springboot+AOP实现动态修改注解并切换数据源项⽬结构
情景描述
异源数据，在⼀个⼯程中处理后，传⼊不同数据库中保存。类似下图所想完成(只会windows⾃带画图)
准备两个测试数据库
上号
不耍流氓，贴pom。

1. springboot启动类
package com.multiple.demo;
batis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration; //禁⽌其⾃动加载配置⽂件
@SpringBootApplication(exclude ={
DataSourceAutoConfiguration.class
})
@MapperScan("com.multiple.demo.dao")
public class SpringbootApplication {
public static void main(String[] args){
SpringApplication.run(SpringbootApplication.class, args);
}
}
2. Controller层
此处可以更改为对应业务逻辑处理
