二、初构属性分组三级菜单
1.抽取三级分类菜单组件
创建一个三级分类组件
目录是module/common/category.vue
2.新建attrgroup.vue
根据菜单目录，在product目录下创建一个attrgroup.vue
3.修改attrgroup布局
1.抽取category三级菜单
2.导入三级菜单组件
import Category from "../common/category";
export default {
//import引入的组件需要注入到对象中才能使用
components: {Category},
<div class="grid-content bg-purple">
<category>category>
div>
3.显示右侧表格
使用代码逆向生成器
4.概览
![[项目练手笔记-谷粒商城（SpringCloud Alibaba+vue前后端分离）]day10属性分组功能编写（三级菜单组件抽离+父子组件交互+前后端级联菜单编写及回显）_第2张图片](http://img.e-com-net.com/image/info8/94b18cea263544c9bc973a197b46f95b.jpg)
三、获取分类属性分组
1.父子组件交互
1.子组件绑定事件
使用事件机制，给父组件传递一个事件，携带上数据
给子组件category绑定一个结点点击事件，携带被点击结点的数据给父组件attrgroup
2.子组件发送数据
nodeClick(data,node,components) {
console.log("子组件事件触发",data,node,components);
this.$emit("tree-node-click",data,node,components);
},
父组件接受响应
3.父组件接受触发
TreeNodeClick(data, node, components) {
console.log("父节点接受到参数", data, node, components);
},
2.查询属性分组
需求：点击菜单获取属性分组在右侧显示
1.修改controller
/**
* 列表
*/
@RequestMapping("/list/{catelogId}")
//@RequiresPermissions("product:attrgroup:list")
public R list(@RequestParam Map<String, Object> params,@PathVariable("catelogId") Long catelogId){
// PageUtils page = attrGroupService.queryPage(params);
PageUtils page = attrGroupService.queryPage(params,catelogId);
return R.ok().put("page", page);
}
2.修改serviceimpl
@Override
public PageUtils queryPage(Map<String, Object> params, Long catelogId) {
if(catelogId==0) {
IPage<AttrGroupEntity> page = this.page(
new Query<AttrGroupEntity>().getPage(params),
new QueryWrapper<AttrGroupEntity>()
);
return new PageUtils(page);
}else {
//select * from pms_attr_group where catlog_id =?and(attr_group_id=key or attr_group_name like %key%)
String key = (String) params.get("key");//获取key的值
QueryWrapper<AttrGroupEntity> queryWrapper = new QueryWrapper<AttrGroupEntity>().eq("catelog_id", catelogId);
//如果接收的key不为空,也就是有查询条件
if (!StringUtils.isEmpty(key)) {
queryWrapper.and((obj)->{
obj.eq("attr_group_id",key).or().like("attr_group_name",key);
});
}
IPage<AttrGroupEntity> page = this.page(
new Query<AttrGroupEntity>().getPage(params),
queryWrapper
);
return new PageUtils(page);
}
}
3.修改前端请求
获取数据方法改变url
// 获取数据列表
getDataList() {
this.dataListLoading = true;
this.$http({
url: this.$http.adornUrl(`/product/attrgroup/list/${this.catId}`),
传递Id
methods: {
TreeNodeClick(data, node, components) {
console.log("父节点接受到参数", data, node, components);
if(node.level==3) {
this.catId = data.catId;
this.getDataList();
}
},
四、添加属性分类
1.使用级联选择器
<el-form-item label="所属分类id" prop="catelogId">
<el-cascader v-model="dataForm.catelogPath" :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: "",
catelogPath: [],
catelogId: 0
},
2.提交catid
// 表单提交
dataFormSubmit() {
this.$refs["dataForm"].validate(valid => {
if (valid) {
this.$http({
url: this.$http.adornUrl(
`/product/attrgroup/${
!this.dataForm.attrGroupId ? "save" : "update"
}`
),
method: "post",
data: this.$http.adornData({
attrGroupId: this.dataForm.attrGroupId || undefined,
attrGroupName: this.dataForm.attrGroupName,
sort: this.dataForm.sort,
descript: this.dataForm.descript,
icon: this.dataForm.icon,
catelogId: this.dataForm.catelogPath[
this.dataForm.catelogPath.length - 1
] //这里提交了最后一个ID查询
})
3.修改entity
新增发现最后一级菜单还有空子菜单
![[项目练手笔记-谷粒商城（SpringCloud Alibaba+vue前后端分离）]day10属性分组功能编写（三级菜单组件抽离+父子组件交互+前后端级联菜单编写及回显）_第3张图片](http://img.e-com-net.com/image/info8/41aaff978017487c957eda8d00393c5c.jpg)
去除办法是修改entity
/**
* 所有子节点
*/
@JsonInclude(value = JsonInclude.Include.NON_EMPTY)
@TableField(exist=false)
private List<CategoryEntity> children;
这样当children为空的时候,就不会有输出
五、回显联级菜单
1.修改AttrGroupEntity
添加属性
/**
* 联级目录路径
*/
@TableField(exist = false)
private Long[] catelogPath;
2.修改controller
/**
* 信息
*/
@RequestMapping("/info/{attrGroupId}")
//@RequiresPermissions("product:attrgroup:info")
public R info(@PathVariable("attrGroupId") Long attrGroupId) {
AttrGroupEntity attrGroup = attrGroupService.getById(attrGroupId);
Long catelogId = attrGroup.getCatelogId();
//获取路径
Long[] path = attrGroupService.getCatelogPath(catelogId);
attrGroup.setCatelogPath(path);
return R.ok().put("attrGroup", attrGroup);
}
3.修改CategoryServiceImpl
/**
* 找到[父/子]路径
* @param catelogId
* @return
*/
@Override
public Long[] getCatelogPath(Long catelogId) {
List<Long> path = new ArrayList<>();//记录路径
getPath(path,catelogId);
return path.toArray(new Long[path.size()]);
}
/**
* 递归查找父节点
* @param path
* @param catelogId
*/
private void getPath(List<Long> path, Long catelogId) {
Long parentCid = this.getById(catelogId).getParentCid();
//只要不是根节点，就继续往上找
if(parentCid!=0) {
getPath(path, parentCid);
}
path.add(catelogId);
}
4.关闭对话框初始函数
dialogClose() {
this.dataForm.catelogPath = [];
},
5.开启级联菜单搜索
