mybatis-plus实现逻辑删除的示例代码

update user set deleted=1 where id = 1 and deleted=0

select id,name,deleted from user where deleted=0

mybatis-plus:
  global-config:
    db-config:
      logic-delete-field: flag # 全局逻辑删除的实体字段名(since 3.3.0,配置后可以忽略不配置步骤2)
      logic-delete-value: 1 # 逻辑已删除值(默认为 1)
      logic-not-delete-value: 0 # 逻辑未删除值(默认为 0)

@Data
public class UserPO implements Serializable {
    @TableId(type = IdType.ASSIGN_ID)
    private Long id;
    private String userName;
    private String password;
    private String nickName;
    @TableLogic
    private int delFlag;
}

@Mapper
public interface UserPOMapper extends BaseMapper<UserPO> {
}

public interface IUserService extends IService<UserPO> {
}

@Service
public class IUserServiceImpl extends ServiceImpl<UserPOMapper, UserPO> implements IUserService {

                .eq(UserPO::getUserName, userParam.getUserName()));
        boolean b = iUserService.removeById(one);
        System.out.println(b);
        return ResultUtil.success(b);
    }
