1、实现mybatis-plus的多个数据库的切换方式
源码地址：https://github.com/baomidou/mybatisplus-spring-mvc
2、因为其文档都是相互依赖的，所以修改配置，就是在已有的配置中修改
这里配置多数据源采用定义不同的profile方式修改启动时连接的数据库

配置文件位置：https://github.com/baomidou/mybatisplus-spring-mvc/tree/master/src/main/resources/spring

修改后配置

项目路径截图
development中写修改的
1 validationQuery=SELECT 1 2 ###############本地数据库 3 jdbc_url=jdbc:mysql://localhost:3306/renttest?characterEncoding=UTF-8 4 ##jdbc_url=jdbc:mysql://192.168.31.255:3306/test?characterEncoding=UTF-8 5 jdbc_username=root 6 jdbc_password=123456
3、beans可以嵌套beans，这是核心配置
<beans profile="development">
<context:property-placeholder
location="classpath*:common/*.properties,classpath*:development/*.properties"/>
<!-- Service包(自动注入) -->
<!-- 修改了package路径 -->
<context:component-scan base-package="com.rent.springmvc.service"/>
<!--导入mybatis-->
<import resource="classpath:spring/spring-mybatis.xml"/>
</beans>
import引入其他配置，这是一份拼接的配置文件
