spring boot:配置mybatis以及注解事务

 

转：https://blog.csdn.net/qq_39320953/article/details/77947947

添加mybatis-spring-boot-starter以及mysql-connector-java依赖：

 

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <scope>runtime</scope>
</dependency>
 
<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>1.3.1</version>
</dependency>

View Code

 

新建entity-数据库对应的实体类： 

public class User {
 
 
private Integer userId;
 
 
private String userName;
 

private Integer userSex;
 
 
//构造方法以及getter、setter省略
 
}
 

View Code

 

因为我特别讨厌繁杂的XML配置文件，所以以下采用的是注解式：

新建UserMapper:

public interface UserMapper {
 
@Select("select * from user")
 
List<User> findAll();
 
}
