spring boot整合mybatis

spring boot整合mybatis 

1.添加mybatis依赖和mysql依赖

<!--mysql-->
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.46</version>
</dependency>

<!--mybatis-->
<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis-spring</artifactId>
    <version>1.3.2</version>
</dependency>

<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis</artifactId>
    <version>3.4.6</version>
</dependency>

<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.0.1</version>
</dependency>
2.编写配置文件
a. application.yml
　　

  b. application-dev.yml

3.在启动类上加上注解@MapperScan("mpper接口所在的包的路径")

4.编写mapper类

5.测试。注：实现CommandLineRunner接口，会做一些初始化的操作
