mybatis升级mybatis-plus

application.yml

  port: 8080

mybatis-plus:

  type-aliases-package: com.xl.xinliao.system.entity


#logging:

pom.xml 升级mybatis-plus要先把先前的mybatis注释掉

<!--添加mysql-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>

        <!--添加mybatis-->
        <!--<dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.0.1</version>
        </dependency>-->
<!--加入mybatis-plus-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.1.1</version>
        </dependency>
        <!--加入lombok简化项目-->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.16.14</version>
            <scope>provided</scope>
        </dependency>

启动类

@SpringBootApplication
@MapperScan("com.xl.xinliao.system.dao")
public class XinliaoApplication {
    public static void main(String[] args) {
        SpringApplication.run(XinliaoApplication.class, args);
        }
 }

spring boot项目结构和之前的spring mvc差不多
也是
@Controller
@RequestMapping(“/login”)
public class LoginController {
}

public interface LoginMapper extends BaseMapper {

}

mybatis-plus读数据库的时候下划线自动转成驼峰形式的。便于在页面显示

@Data
@TableName(“login”)
public class Login extends Model {
private static final long serialVersionUID = 1L;
@TableId(value = “id”, type = IdType.AUTO)
private long Id;//
}

public interface ILoginService extends IService {}

@Service
public class LoginServiceImpl extends ServiceImpl<LoginMapper, Login> implements ILoginService {}

简单的分层

你们的观看是我前进的动力，这个是我最近从mybatis升级mybatis-plus的一些操作，其中也遇到很多毛病

多谢支持
