mybatis配置 （註解版）

mybatis配置 （註解版）

導入依賴

<dependency>    
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>1.1.1</version>
</dependency>
<dependency>    
    <groupId>mysql</groupId>    
    <artifactId>mysql-connector-java</artifactId>
</dependency>

在配置文件中配置數據庫信息

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/spring?serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=983626hu

創建對應的實體類
創建對應的方法接口 注：標註 @Mapper

@Mapper
public interface UserMapper {    
    @Select("此處填寫sql語句")
    public List<Account> queryList();
}

創建類測試

@Autowired
private UserMapper userMapper;
@RequestMapping("/query")
@ResponseBody
public List<Account> queryList(){    
    List<Account> accounts = userMapper.queryList();    
    return accounts;
}
