✅P50_三级分类-删除-逻辑删除

物理删除

cfmall-product/src/main/java/com/gyz/cfmall/product/controller/CategoryController.java

@RestController
@RequestMapping("product/category")
public class CategoryController {
    /**
     * 删除
     */
    @RequestMapping("/delete")
    public R delete(@RequestBody Long[] catIds) {
        categoryService.removeMenuByIds(Arrays.asList(catIds));
        return R.ok();
    }
}

cfmall-product/src/main/java/com/gyz/cfmall/product/service/impl/CategoryServiceImpl.java

@Service("categoryService")
public class CategoryServiceImpl extends ServiceImpl<CategoryDao, CategoryEntity> implements CategoryService {
    @Override
    public void removeMenuByIds(List<Long> asList) {
        //TODO 检查当前删除的菜单，是否被别的地方引用

        //逻辑删除
        baseMapper.deleteBatchIds(asList);
    }	
}

删除测试

发现数据库中cat_id=1432的数据被删除了。

逻辑删除

1、在逻辑删除字段上加上注解 @TableLogic

cfmall-product/src/main/java/com/gyz/cfmall/product/entity/CategoryEntity.java

/**
 * 是否显示[0-不显示，1显示]
 */
@TableLogic(value = "1",delval = "0")
private Integer showStatus;

2、配置 application.yml

cfmall-product/src/main/resources/application.yml

mybatis-plus:
  mapper-locations: classpath:/mapper/**/*.xml
  #设置实体类的自增主键
  global-config:
    db-config:
      id-type: auto
      #逻辑删除
      logic-delete-value: 1
      logic-not-delete-value: 0

3、测试

测试发现 show_status 字段会由1变成0
