springboot整合mybatis

1、在pom.xml中导入mybatis-spring-boot-starter

<!-- https://mvnrepository.com/artifact/org.mybatis.spring.boot/mybatis-spring-boot-starter -->
<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.1.1</version>
</dependency>


2、配置application.properties或者.yml

spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.url=jdbc:mysql://localhost:3306/mybatis?useUnicode=true&characterEncoding=utf-8
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

3、database中连接数据库

 

 4、根据数据库写pojo层

 

 

 

5、写mapper层接口

@Mapper注解：这个注解表示了这是一个mybatis的mapper类
