2. Front-end component extraction

Now I want to click on the left side of the menu to display data on the right side

(1) The extraction module is stored in common

Create a view/modulesnew commonfolder to store the modules that need to be extracted

extract category.vue, left content

<template>
  <div>
    <el-input placeholder="输入关键字进行过滤" v-model="filterText"></el-input>
    <el-tree
      :data="menus"
      :props="defaultProps"
      node-key="catId"
      ref="menuTree"
      @node-click="nodeclick"
      :filter-node-method="filterNode"
      :highlight-current = "true"
    ></el-tree>
  </div>
</template>

<script>
//这里可以导入其他文件（比如：组件，工具js，第三方插件js，json文件，图片文件等等）
//例如：import 《组件名称》 from '《组件路径》';

export default {
    
    
  //import引入的组件需要注入到对象中才能使用
  components: {
    
    },
  props: {
    
    },
  data() {
    
    
    //这里存放数据
    return {
    
    
      filterText: "",
      menus: [],
      expandedKey: [],
      defaultProps: {
    
    
        children: "children",
        label: "name"
      }
    };
  },
  //计算属性 类似于data概念
  computed: {
    
    },
  //监控data中的数据变化
  watch: {
    
    
    filterText(val) {
    
    
      this.$refs.menuTree.filter(val);
    }
  },
  //方法集合
  methods: {
    
    
    //树节点过滤
    filterNode(value, data) {
    
    
      if (!value) return true;
      return data.name.indexOf(value) !== -1;
    },
    getMenus() {
    
    
      this.$http({
    
    
        url: this.$http.adornUrl("/product/category/list/tree"),
        method: "get"
      }).then(({
    
     data }) => {
    
    
        this.menus = data.data;
      });
    },
    nodeclick(data, node, component) {
    
    
      console.log("子组件category的节点被点击", data, node, component);
      //向父组件发送事件；
      this.$emit("tree-node-click", data, node, component);
    }
  },
  //生命周期 - 创建完成（可以访问当前this实例）
  created() {
    
    
    this.getMenus();
  },
  //生命周期 - 挂载完成（可以访问DOM元素）
  mounted() {
    
    },
  beforeCreate() {
    
    }, //生命周期 - 创建之前
  beforeMount() {
    
    }, //生命周期 - 挂载之前
  beforeUpdate() {
    
    }, //生命周期 - 更新之前
  updated() {
    
    }, //生命周期 - 更新之后
  beforeDestroy() {
    
    }, //生命周期 - 销毁之前
  destroyed() {
    
    }, //生命周期 - 销毁完成
  activated() {
    
    } //如果页面有keep-alive缓存功能，这个函数会触发

3. Parent-child components pass data

To realize the function: click on the left side, and the corresponding content will be displayed in the table on the right side.

Parent-child components pass data: category.vuewhen clicked, those who refer attgroup.vueto it can perceive it, and then notifyadd-or-update

(1) The child component passes data to the parent component

• The child component ( ) passes data categoryto the parent component ( ), using the event mechanismattrgroup
• The child component sends an event to the parent component and carries the data,this.$emit
• node-click : the callback when the node is clicked, categorythe middle binding event@node-click="nodeclick"

<el-tree :data="menus" :props="defaultProps" node-key="catId" ref="menuTree" @node-click="nodeclick" :filter-node-method="filterNode" :highlight-current="true"></el-tree>

// 点击节点触发的事件
    nodeclick(data, node, component) {
    
    
      console.log("子组件category的节点被点击", data, node, component);
      //向父组件发送事件；
      this.$emit("tree-node-click", data, node, component);
    }

(2) Get the sent event in the parent component

// 表明他的子组件可能会传递过来点击事件，用自定义的函数接收传递过来的参数
<category  @tree-node-click="treeNodeClick"></category>

 // 1.获取发送的事件数据
    treeNodeClick(data, Node, component) {
    
    
      console.log("attgroup感知到的category的节点被点击", data, Node, component);
      console.log("刚才被点击的菜单ID", data.catId);
    },

4. Obtain classification attribute grouping

1. ReviseAttrGroupController

  /**
     * 列表
     */
    @RequestMapping("/list/{catelogId}")
    public R list(@RequestParam Map<String, Object> params, @PathVariable("catelogId") Long catelogId) {
    
    

//        PageUtils page = attrGroupService.queryPage(params);
        PageUtils page = attrGroupService.queryPage(params,catelogId);
        return R.ok().put("page", page);
    }

2. AttrGroupServiceImpl

 // 根据分类返回属性分组,按关键字或者按id查
    @Override
    public PageUtils queryPage(Map<String, Object> params, Long catelogId) {
    
    

        String key = (String) params.get("key");
        QueryWrapper<AttrGroupEntity> wrapper = new QueryWrapper<>();

        // select * from AttrGroup where attr_group_id='key' or attr_group_name like 'key'
        if (!StringUtils.isEmpty(key)) {
    
    
            // 传入consumer
            wrapper.and((obj) ->
                    obj.eq("attr_group_id", key).or().like("attr_group_name", key)
            );
        }

        //  0的话查所有
        if (catelogId == 0) {
    
    
            // Query可以把map封装为IPage
            IPage<AttrGroupEntity> page = this.page(new Query<AttrGroupEntity>().getPage(params), wrapper);
            return new PageUtils(page);
        } else {
    
    
            wrapper.eq("catelog_id", catelogId);
            IPage<AttrGroupEntity> page = this.page(new Query<AttrGroupEntity>().getPage(params), wrapper);
            return new PageUtils(page);
        }
    }

3. front-end processing
   attrgroup.vue

data() {
    
    
    //这里存放数据
    return {
    
    
      catId: 0,
      
      }
   }
   
// 1.获取发送的事件数据,感知树节点被点击
    treeNodeClick(data, node, component) {
    
    
    
      if (node.level == 3) {
    
    
        this.catId = data.catId;
        this.getDataList(); //重新查询
      }
    },

	 this.$http({
    
    
	        url: this.$http.adornUrl(`/product/attrgroup/list/${
    
    this.catId}`),
	        method: 'get',
	        params: this.$http.adornParams({
    
    
	          'page': this.pageIndex,
	          'limit': this.pageSize,
	          'key': this.dataForm.key
	        })

5. New grouping

(1) Cascade selector<el-cascader>

• categoryIds: [] accepts an array of category ids, and submits the last id when submitting

attrgroup-add-or-update.vue

 <el-form-item label="所属分类id" prop="catelogId">
        <!-- <el-input v-model="dataForm.catelogId" placeholder="所属分类id"></el-input> @change="handleChange" -->
        <el-cascader filterable placeholder="试试搜索：手机" v-model="dataForm.catelogIds" :options="categorys" :props="props"></el-cascader>
      </el-form-item>

  data() {
    
    
    return {
    
    
      props: {
    
    
        value: "catId",
        label: "name",
        children: "children"
      },
      categorys: [],
        dataForm: {
    
    
        attrGroupId: 0,
        attrGroupName: '',
        sort: '',
        descript: '',
        icon: '',
        catelogIds: [],
        catelogId: 0
      },

(2) Optimization

When there is no lower-level menu, do not have a lower-level empty menu. On the java side, remove the null value of the children attribute, and
remove the field when the collection is empty.

Can be annotated with @JsonInclude(Inlcude.NON_EMPTY) on the properties of the entity class

@JsonInclude(JsonInclude.Include.NON_EMPTY)
	@TableField(exist = false)
	private List<CategoryEntity> children;

6. Modify the echo

Echo level 3 when modifying, echo in the init method

1. 
   attrgroup-add-or-update.vueIn front-end modification and optimization, catelogIdsreplace all withcatelogPath

 init(id) {
    
    
      ...
       // 查出catelogId的完整路径
        this.dataForm.catelogPath =  data.attrGroup.catelogPath;
            }
          })
        }
      })
    },

2. Modify the backend interface
   AttrGroupEntityto add catelogPathfields

@TableField(exist = false)
	private Long[] catelogPath;

AttrGroupController

 @RequestMapping("/info/{attrGroupId}")
    public R info(@PathVariable("attrGroupId") Long attrGroupId) {
    
    
        AttrGroupEntity attrGroup = attrGroupService.getById(attrGroupId);

        // 1.当前catelogId
        Long catelogId = attrGroup.getCatelogId();

        // 2.根据 当前路径找到完整路径
        Long[] path = categoryService.findCateLogPath(catelogId);

        // 3. 设置完整路径
        attrGroup.setCatelogPath(path);

        return R.ok().put("attrGroup", attrGroup);
    }

CategoryService

  /**
     * 找到catelogId的完整路径
     * 父/子/孙
     * @param catelogId
     * @return
     */
    Long[] findCateLogPath(Long catelogId);

CategoryServiceImpl

 // 找到catelogId的完整路径
    @Override
    public Long[] findCateLogPath(Long catelogId) {
    
    
        List<Long> paths = new ArrayList<>();
        List<Long> parentPath = findParentPath(catelogId, paths);
        // 收集的时候是顺序 前端是逆序显示的 所以用集合工具类给它逆序一下
        Collections.reverse(parentPath);
        return (Long[]) parentPath.toArray();

    }

    //递归收集所有父节点
    private List<Long> findParentPath(Long catlogId, List<Long> paths) {
    
    
        // 1、收集当前节点id
        paths.add(catlogId);
        // 2、查找当前节点的详细信息
        CategoryEntity byId = this.getById(catlogId);
        // 3、有父id
        if (byId.getParentCid() != 0) {
    
    
            // 4、递归查找
            findParentPath(byId.getParentCid(), paths);
        }
        return paths;
    }

3. Optimized
   to clear the content when the session is closed to prevent the remaining data from being opened next time

• The listening dialog is closed:@closed="dialogClose"
• Clear the data when the dialog is closed

 <el-dialog :title="!dataForm.attrGroupId ? '新增' : '修改'" :close-on-click-modal="false" :visible.sync="visible" @closed="dialogClose">

  methods: {
    
    

	// 2. 对话框关闭时清空数据
    dialogClose(){
    
    
      this.dataForm.catelogPath=[];
    },

• filterableCascading selectors are searchable
