SpringBlade bug 字典管理 修改父节点编号问题

一、问题：

修改了父节点的编号，子项的编号不会自动修改

1、大图

2、小图

二、解决

后台

1、DictMapper.xml

    <select id="getChildren" resultMap="dictResultMap">
        select * from blade_dict where parent_id = #{param1} and is_deleted = 0
    </select>

2、DictMapper.java

	/**
	 * 获取子节点
	 * @param parentId 父节点Id
	 * @return
	 */
	List<Dict> getChildren(Long parentId);

3、改的这两个文件

4、DictServiceImpl.java

	@Cacheable(cacheNames = DICT_LIST, key = "#code")
	public List<Dict> getChildren(Long parentId) {
		return baseMapper.getChildren(parentId);
	}


	@Override
	@CacheEvict(cacheNames = {DICT_LIST, DICT_VALUE}, allEntries = true)
	public boolean submit(Dict dict) {
		LambdaQueryWrapper<Dict> lqw = Wrappers.<Dict>query().lambda().eq(Dict::getCode, dict.getCode()).eq(Dict::getDictKey, dict.getDictKey());
		Integer cnt = baseMapper.selectCount((Func.isEmpty(dict.getId())) ? lqw : lqw.notIn(Dict::getId, dict.getId()));
		if (cnt > 0) {
			throw new ApiException("当前字典键值已存在!");
		}

		if (Func.isNotEmpty(dict.getId()) && (dict.getId() > 0)) {// 改变子项的Code
			Dict dbDict = getById(dict.getId());
			if (!dict.getCode().equals(dbDict.getCode())) {
				List<Dict> children = getChildren(dict.getId());
				int num = children.size();
				for (int i = 0; i < num; i++) {
					children.get(i).setCode(dict.getCode());
				}
				updateBatchById(children);// 查询的实体，如果没有id，则无法更新数据
			}
		}

		if (Func.isEmpty(dict.getSort())) {// 自动生成排序字段
			Integer sort = 1;
			Long parentId = Func.isEmpty(dict.getParentId()) ? 0 : dict.getParentId();
			List<Dict> children = getChildren(parentId);
			if (Func.isNotEmpty(children)){
				sort = children.stream().max(Comparator.comparing(Dict::getSort)).get().getSort() + 1;
			}
			dict.setSort(sort);
		}

		return saveOrUpdate(dict);
	}

5、改的这里

前端

1、字段修改

            {
              label: "字典排序",
              prop: "sort",
              type: "number",
              rules: [{
                required: false,
                message: "请输入字典排序",
                trigger: "blur"
              }]

2、跟组件添加事件

组件avue-crud，添加事件:before-close="beforeClose"

3、事件的具体代码

      beforeClose(done, type) {// 关闭页面的时候，取消掉已有的禁用状态和赋值
        if (["add"].includes(type)) {
          this.$refs.crud.value.parentId = '';
          this.$refs.crud.option.column.filter(item => {
            if (item.prop === "parentId") {
              item.value = '';
              item.addDisabled = false;
            }else if (item.prop === "code") {
              item.value = '';
              item.addDisabled = false;
            }
          });
        }
        done();
      },
