Mybatis Plus AR模型

1、构建实体

/**
 * @author beth
 * @data 2019-10-20 22:30
 */
@Data
@EqualsAndHashCode(callSuper = false)
public class UserInfo extends Model<UserInfo> {
    
    private static final long serialVersionUID = 1L;

    /**
     * 密码
     */
    private String password;

    /**
     * 用户名
     */
    private String username;

    /**
     * 年龄
     */
    private Integer age;

    /**
     * 建立时间
     */
    private LocalDateTime createTime;

    /**
     * 修改时间
     */
    private LocalDateTime updateTime;

    /**
     * 邮箱
     */
    private String email;

    /**
     * 电话
     */
    private String phone;

    /**
     * 上级
     */
    private String parentId;

}

2、必要的mapper

@Repository
public interface UserInfoMapper extends BaseMapper<UserInfo> {
}

3、测试

/**
 * @author beth
 * @data 2019-10-20 22:35
 */
public class ARTest {

    /**
     * 新增
     */
    @Test
    public void insert() {
        UserInfo userInfo = new UserInfo();
        userInfo.setUsername("肖娟");
        userInfo.setAge(29);
        userInfo.setEmail("xj@qq.com");
        userInfo.setParentId("445465");
        userInfo.setCreateTime(LocalDateTime.now());
        boolean insert = userInfo.insert();
    }

    /**
     * 根据id查询
     */
    @Test
    public void selectById() {
        UserInfo userInfo = new UserInfo();
        UserInfo userInfoSelect = userInfo.selectById("3243543534");
        System.out.println(userInfo == userInfoSelect);
        System.out.println(userInfoSelect);
    }

    /**
     * 根据id查询
     */
    @Test
    public void selectById2() {
        UserInfo userInfo = new UserInfo();
        userInfo.setId("54543545");
        UserInfo userInfoSelect = userInfo.selectById();
        System.out.println(userInfo == userInfoSelect);
        System.out.println(userInfoSelect);
    }

    /**
     * 根据id删除
     */
    @Test
    public void deleteById() {
        UserInfo userInfo = new UserInfo();
        userInfo.setId("54543545");
        boolean r = userInfo.deleteById();
        System.out.println(r);
    }

    /**
     * 新增或修改
     */
    @Test
    public void insertOrUpdate() {
        UserInfo userInfo = new UserInfo();
        userInfo.setUsername("肖娟");
        userInfo.setAge(29);
        userInfo.setEmail("xj@qq.com");
        userInfo.setParentId("445465");
        userInfo.setCreateTime(LocalDateTime.now());
        boolean insert = userInfo.insertOrUpdate();
    }
}
```
