一、在表中新增欄位deleted，對應實體類中新增屬性，屬性添加註解。
新增maven

<dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.4.1</version>
</dependency>

在基類上新增deleted欄位和註解

@Data
public class BaseTable {
    @TableId(type = IdType.ID_WORKER)
    private Long id;

    @Version
    @TableField(fill = FieldFill.INSERT)
    private Integer version;

    @TableField(fill = FieldFill.INSERT)
    private Date createTime;

    @TableField(fill = FieldFill.INSERT_UPDATE)
    private
 
 Date updateTime;

    @TableLogic
    private Integer deleted;
}

實體類繼承基類

@Data
@TableName("tb_user")
public class User extends BaseTable{
    private String name;
    private Integer age;
}

測試：

@DisplayName("Junit5功能測試類")
@SpringBootTest
class SpringMvdApplicationTests {
    @Autowired
 

    private UserService userService;

    @Autowired
    private NewUserMapper userMapper;

    //測試邏輯刪除
    @Test
    public void testDelete() {
        userService.removeById(1350351840632295425L);
    }

}

結果：
