springboot 集成 mybatis

Posted 2020-12-29 黄光跃

1，添加依赖

<!-- mybatis -->
<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>1.3.2</version>
</dependency>
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <scope>runtime</scope>
</dependency>

2，数据源

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8
spring.datasource.username=root
spring.datasource.password=111111

3，指明映射文件路径

可以在配置文件配置，也可以在启动类添加注解：@MapperScan(" pojo 所在包名")

4，mybatis 自动生成工具干活了
