Springboot整合MybatisPuls
Maven导入依赖,主要只需导入MyBatisPuls
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jdbc</artifactId> </dependency> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.0.1</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency>
配置数据源
spring.datasource.username=root spring.datasource.password=root spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver spring.datasource.url=jdbc:mysql://localhost:3306/springboot?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC server.port=8082
编写实体类
@Data @AllArgsConstructor @NoArgsConstructor @TableName("users")//连接的表名 public class Users implements Serializable { @TableId("id")标记该变量为主键 private Integer id; private String Account; @TableField("passwraod" )//如果实体类变量和数据库不同使用 private String password; private Integer Authority; }
mapper接口编写
继承BaseMapper<这里为实体类>
@org.apache.ibatis.annotations.Mapper//让Spring容器扫描该类为Mapper @Repository public interface Mapper extends BaseMapper<Users> { }
BaseMapper源码
实现接口方法
@RestController public class Control { @Autowired Mapper mapper; @RequestMapping("/hello") public Users Select(){ Users users = mapper.selectById(1); return users; } }
