谷粒商城–属性分组–笔记七
1.SPU与SKU
SPU: Standard Product Unit(标准化产品单元)
是商品信息聚合的最小单位, 是一组可复用、 易检索的标准化信息的集合, 该集合描述了一个产品的特性。
- iphoneX 是 SPU、 MI 8 是 SPU
- iphoneX 64G 黑曜石 是 SKU
- MI8 8+64G+黑色 是 SKU
SKU: Stock Keeping Unit(库存量单位)
即库存进出计量的基本单元, 可以是以件, 盒, 托盘等为单位。 SKU 这是对于大型连锁超市DC(配送中心) 物流管理的一个必要的方法。 现在已经被引申为产品统一编号的简称, 每种产品均对应有唯一的 SKU 号。
2.基本属性【 规格参数】 与销售属性
每个分类下的商品共享规格参数, 与销售属性。 只是有些商品不一定要用这个分类下全部的属性;
- 属性是以三级分类组织起来的
- 规格参数中有些是可以提供检索的
- 规格参数也是基本属性, 他们具有自己的分组
- 属性的分组也是以三级分类组织起来的
- 属性名确定的, 但是值是每一个 商品不同来决定的
3.新增菜单
执行sys_menus.sql或gulimall_admin.sql
数据库
前端
4.属性分组模块 attrgroup.vue
新建文件attrgroup.vue src/views/modules/product/attrgroup.vue
布局
<template>
<el-row :gutter="20">
<el-col :span="6">
分类列表
</el-col>
<el-col :span="18">
表单
</el-col>
</el-row>
</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 {
};
},
//计算属性 类似于 data 概念
computed: {},
//监控 data 中的数据变化
watch: {},
//方法集合
methods: {
},
//生命周期 - 创建完成(可以访问当前 this 实例)
created() {
},
//生命周期 - 挂载完成(可以访问 DOM 元素)
mounted() {
},
//生命周期 - 创建之前
beforeCreate() {},
//生命周期 - 挂载之前
beforeMount() {},
//生命周期 - 更新之前
beforeUpdate() {},
//生命周期 - 更新之后
updated() {},
//生命周期 - 销毁之前
beforeDestroy() {},
//生命周期 - 销毁完成
destroyed() {},
//如果页面有 keep-alive 缓存功能, 这个函数会触发
activated() {},
}
</script>
<style lang='scss' scoped>
//@import url(); 引入公共 css 类
</style>
5.前端分类列表组件抽取 category.vue
因为分类列表在其他地方也会使用到,所以单独抽取出来封装成组件
新建一个category.vue 位置:src/views/modules/common/category.vue
1.完整示例
<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.$refs.menuTree.filter(val);
}
},
//方法集合
methods: {
//树节点过滤
filterNode(value, data) {
//如果没有输入值就返回true,表示所有节点都能显示
if (!value) return true;
//有值就模糊查询
return data.name.indexOf(value) !== -1;
},
getMenus() {
this.$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
};
</script>
<style scoped>
</style>
2.列表不显示问题
发送请求成功,也获取到数据了,但是列表不显示
解决
参数 | 说明 | 类型 | 可选值 | 默认值 |
---|---|---|---|---|
label | 指定节点标签为节点对象的某个属性值 | string, function(data, node) | — | — |
children | 指定子树为节点对象的某个属性值 | string | — | — |
disabled | 指定节点选择框是否禁用为节点对象的某个属性值 | boolean, function(data, node) | — | — |
isLeaf | 指定节点是否为叶子节点,仅在指定了 lazy 属性的情况下生效 | boolean, function(data, node) | — | — |
通过设置props的label与children属性来解决
解决效果
3.输入关键字进行过滤
filter-node-method:对树节点进行筛选时执行的方法,返回 true 表示这个节点可以显示,返回 false 则表示这个节点会被隐藏
返回值:Function(value, data, node)
value:筛选的值
data:筛选的数据
node:筛选的节点
4.子组件向父节点传值(利用事件)
node-click:节点被点击时的回调
回调函数:共三个参数,依次为:传递给
data
属性的数组中该节点所对应的对象、节点对应的 Node、节点组件本身。
1.子传值
//tree-node-click随便取值,只要在父组件取名相同
//后面参数为传的值
this.$emit("tree-node-click", data, node, component);
2.父取值
<!--此处@tree-node-click必须与子组件取名相同-->
<category @tree-node-click="treenodeclick"></category>
6.将抽取的组件注册到attrgroup
1.导入
import Category from "../common/category";
2.组件注册
components: {
Category
},
3.使用
<category @tree-node-click="treenodeclick"></category>
4.此部分代码
<template>
<el-row :gutter="20">
<el-col :span="6">
<category @tree-node-click="treenodeclick"></category>
</el-col>
<el-col :span="18">
表单
</el-col>
</el-row>
</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》 ';
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
},
props: {},
data() {
//这里存放数据
return {
};
},
//计算属性 类似于 data 概念
computed: {},
//监控 data 中的数据变化
watch: {},
//方法集合
methods: {
},
//生命周期 - 创建完成(可以访问当前 this 实例)
created() {
},
//生命周期 - 挂载完成(可以访问 DOM 元素)
mounted() {
},
//生命周期 - 创建之前
beforeCreate() {},
//生命周期 - 挂载之前
beforeMount() {},
//生命周期 - 更新之前
beforeUpdate() {},
//生命周期 - 更新之后
updated() {},
//生命周期 - 销毁之前
beforeDestroy() {},
//生命周期 - 销毁完成
destroyed() {},
//如果页面有 keep-alive 缓存功能, 这个函数会触发
activated() {},
}
</script>
<style lang='scss' scoped>
//@import url(); 引入公共 css 类
</style>

1.级联选择器 (父传子)
为所属分类字段新增级联选择器
组件定义 src/views/modules/common/category-cascader.vue
<template>
<!--
使用说明:
1)、引入category-cascader.vue
2)、语法:<category-cascader :catelogPath.sync="catelogPath"></category-cascader>
解释:
catelogPath:指定的值是cascader初始化需要显示的值,应该和父组件的catelogPath绑定;
由于有sync修饰符,所以cascader路径变化以后自动会修改父的catelogPath,这是结合子组件this.$emit("update:catelogPath",v);做的

遇到的问题
原因
三级子分类中没有子节点了导致数组为空
解决
让没有子节点的分类,不传children字段
修改gulimall-product/src/main/java/site/zhourui/gulimall/product/entity/CategoryEntity.java
/**
* 子目录集合
*/
//为空就不传值
@JsonInclude(JsonInclude.Include.NON_EMPTY)
//此字段在数据库表中不存在
@TableField(exist=false)
private List<CategoryEntity> children;
效果
2.级联回显
但现在所属分类id,只有三级分类的id
想要在编辑时回显级联分类,就必须新增后端接口,根据三级分类id查询分类路径id数组
新增根据三级分类id查询分类路径id数组
为gulimall-product/src/main/java/site/zhourui/gulimall/product/entity/AttrGroupEntity.java新增字段
/**
* 目录路径
*/
@TableField(exist = false)
private Long[] catelogPath;
gulimall-product/src/main/java/site/zhourui/gulimall/product/service/impl/CategoryServiceImpl.java
新增接口
/**
* 找到catelogId的完整路径;
* [父/子/孙]
* @param catelogId
* @return
*/
Long[] findCatelogPath(Long catelogId);
gulimall-product/src/main/java/site/zhourui/gulimall/product/service/impl/AttrGroupServiceImpl.java
新增接口实现
//[2,25,225]
@Override
public Long[] findCatelogPath(Long catelogId) {
List<Long> paths = new ArrayList<>();
List<Long> parentPath = findParentPath(catelogId, paths);
//反序操作
Collections.reverse(parentPath);
return parentPath.toArray(new Long[parentPath.size()]);
}
//225,25,2
//根据catelogId查询出目录路径数组,此时是逆序的 (递归操作)
private List<Long> findParentPath(Long catelogId,List<Long> paths){
//1、收集当前节点id
paths.add(catelogId);
CategoryEntity byId = this.getById(catelogId);
//找到根节点才会停止
if(byId.getParentCid()!=0){
findParentPath(byId.getParentCid(),paths);
}
return paths;
}
修改gulimall-product/src/main/java/site/zhourui/gulimall/product/controller/AttrGroupController.java info方法
@Autowired
private CategoryService categoryService;
/**
* 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();
Long[] path = categoryService.findCatelogPath(catelogId);
attrGroup.setCatelogPath(path);
return R.ok().put("attrGroup", attrGroup);
}
级联回显效果
8.新增后端接口
gulimall-product/src/main/java/site/zhourui/gulimall/product/service/AttrGroupService.java
新增接口
/**
* 根据catelogId查询属性分组
* @param params
* @param catelogId
* @return
*/
PageUtils queryPage(Map<String, Object> params, Long catelogId);
gulimall-product/src/main/java/site/zhourui/gulimall/product/service/impl/AttrGroupServiceImpl.java
新增接口实现
@Override
public PageUtils queryPage(Map<String, Object> params, Long catelogId) {
String key = (String) params.get("key");
//select * from pms_attr_group where catelog_id=? and (attr_group_id=key or attr_group_name like %key%)
QueryWrapper<AttrGroupEntity> wrapper = new QueryWrapper<AttrGroupEntity>();
if(!StringUtils.isEmpty(key)){
wrapper.and((obj)->{
obj.eq("attr_group_id",key).or().like("attr_group_name",key);
});
}
if( catelogId == 0){
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);
}
}
gulimall-product/src/main/java/site/zhourui/gulimall/product/controller/AttrGroupController.java
修改list接口
/**
* 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);
}
测试http://localhost:88/api/product/attrgroup/list/0?t=1633946911824&page=1&limit=10&key=
结果
前端调用结果:
