• 启动类

  @SpringBootApplication
  @MapperScan("com.mq.logicdelete.mapper")
  public class LogicdeleteApplication {
  ​
      public static void main(String[] args) {
          SpringApplication.run(LogicdeleteApplication.class, args);
      }
  ​
  }
  ​

• 实体类

  @Data
  public class User {
      private Integer id;
      private String name;
      private Integer age;
      private String email;
      @TableLogic
      private Integer isDelete;
  }

• dao层

  public interface UserMapper extends BaseMapper<User> {
  ​
  }
  ​

• 数据库脚本

  DELETE FROM user;
  ​
  INSERT INTO user (id, name, age, email) VALUES
  (1, 'Jone', 18, 'test1@baomidou.com'),
  (2, 'Jack', 20, 'test2@baomidou.com'),
  (3, 'Tom', 28, 'test3@baomidou.com'),
  (4, 'Sandy', 21, 'test4@baomidou.com'),
  (5, 'Billie', 24, 'test5@baomidou.com');
  ​
  DROP TABLE IF EXISTS user;
  ​
  CREATE TABLE user
  (
      id BIGINT(20) NOT NULL COMMENT '主键ID',
      name VARCHAR(30) NULL DEFAULT NULL COMMENT '姓名',
      age INT(11) NULL DEFAULT NULL COMMENT '年龄',
      email VARCHAR(50) NULL DEFAULT NULL COMMENT '邮箱',
      is_delete INT(11) NOT NULL DEFAULT 0 COMMENT '是否删除',
      PRIMARY KEY (id)
  );

• 测试类

  @RunWith(SpringRunner.class)
  @SpringBootTest
  class LogicdeleteApplicationTests {
  ​
      @Resource
      private UserMapper userMapper;
  ​
      @Test
      public void testLogicDeleteById() {
          userMapper.deleteById(1);
      }
  ​
      @Test
      public void testLogicDeleteBatchIds() {
          userMapper.deleteBatchIds(Arrays.asList(1, 2, 3));
      }
  ​
      @Test
      public void testLogicDelete() {
          userMapper.delete(new QueryWrapper<User>().eq("age", 2));
      }
  ​
  }

• 测试结果，运行部分测试代码（其实底层的是update语句）
