谷粒商城第二篇服务功能-商品服务-三级分类
商品服务三级分类工程初始化及查询搭建
在数据库中插入数据
1.controller类
@RestController
@RequestMapping("product/category")
public class CategoryController {
@Autowired
private CategoryService categoryService;
/**
* 查出所有分类以及子分类，以树形结构组装起来
*/
@RequestMapping("/list/tree")
public R list(){
List<CategoryEntity> entityList = categoryService.listWithTree();
return R.ok().put("data", entityList);
}
}
2.service类
@Service("categoryService")
public class CategoryServiceImpl extends ServiceImpl<CategoryDao, CategoryEntity> implements CategoryService {
@Override
public List<CategoryEntity> listWithTree(){
// 1. 查出所有分类
List<CategoryEntity> categoryEntities = baseMapper.selectList(null);
// 2.组装成父子的树形结构
// 查找以及分类
List<CategoryEntity> level1Menu = categoryEntities.stream().filter((categoryEntity -> {
return categoryEntity.getParentCid() == 0;
})).map((menu)->{
menu.setChildren(getChildrens(menu,categoryEntities));
return menu;
}).sorted((menu1,menu2)->{
return (menu1.getSort()==null?0:menu1.getSort())-(menu2.getSort()==null?0:menu2.getSort());
}).collect(Collectors.toList());
return level1Menu;
}
// 递归查找所有菜单的子菜单
private List<CategoryEntity> getChildrens(CategoryEntity root,List<CategoryEntity> all){
List<CategoryEntity> children = all.stream().filter(categoryEntity -> {
return categoryEntity.getParentCid() == root.getCatId();
}).map(categoryEntity -> {
// 1.找到子菜单
categoryEntity.setChildren(getChildrens(categoryEntity, all));
return categoryEntity;
}).sorted((menu1, menu2) -> {
// 2.菜单的排序
return (menu1.getSort() == null ? 0 : menu1.getSort()) - (menu2.getSort() == null ? 0 : menu2.getSort());
}).collect(Collectors.toList());
return children;
}
}
3.测试
4.启动renren前端及后端工程，进入工程创建商品目录
5.在商品系统下创建分类维护菜单
6.创建category模块并且测试
7.编写代码
category.vue
<template>
<el-tree :data="data" :props="defaultProps" @node-click="handleNodeClick"></el-tree>
</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: {},
data() {
return {
data: [],
defaultProps: {
children: 'children',
label: 'label'
}
};
},
methods: {
handleNodeClick(data) {
console.log(data);
},
getMenus() {
this.dataListLoading = true
this.$http({
url: this.$http.adornUrl('/product/category/list/tree'),
method: 'get'
}).then(data=>{
console.log("成功获取到菜单数据...",data)
})
}
},
// 监听属性 类似于data概念
computed: {},
// 监控data中的数据变化
watch: {},
// 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>
访问页面路径端和端口都不对
8.修改为所有请求调用网关
修改index.js 修改为网关地址,现在前端访问后端renrenfast会报错
9.将renrenfast加入注册中心中
1.在renren-fast后端工程加入gulimall-common,并且修改springboot版本，以及对应cloud版本

2.启动参数中加上@EnableDiscouveryClient
3.配置文件加上注册中心配置
4.启动工程
10.修改网关工程，配置转发
修改网关配置加上/api即可路由到
spring:
# datasource:
# username: root
# password: 1q1w1e1r
# url: jdbc:mysql://127.0.0.1:3306/gulimall_sms
# driver-class-name: com.mysql.cj.jdbc.Driver
cloud:
nacos:
discovery:
server-addr: 127.0.0.1:8848
gateway:
routes:
- id: test_route
uri: https://www.baidu.com
predicates:
- Query=url,baidu
- id: qq_route
uri: https://www.qq.com
predicates:
- Query=url,qq
# 前端项目,/api
- id: admin_route
uri: lb://renren-fast
predicates:
- Path=/api/**
server:
port: 88
前端所有请求加上/api
11.测试并调整网关
访问主页有报错
因为网关转发的时候,未带工程前缀
http://localhost:88/api/captcha.jpg ====> http://renren-fast:8080/api/captcha.jpg
修改gateway工程加上重写的工程路径
# 前端项目,/api
# http://localhost:88/api/captcha.jpg http://renren-fast:8080/api/captcha.jpg
- id: admin_route
uri: lb://renren-fast
predicates:
- Path=/api/**
filters:
- RewritePath=/api/?(?.*), /renren-fast/$\{segment}
重启gateway再次访问页面即可看到验证码
12.登录跨域问题
1.原因
由于浏览器为http://localhost:8001/#/login，前端中的js访问资源协议域名端口不一样即会有跨域问题
登录方法为OPTIONS
2.跨域流程
跨域解释
https://developer.mozilla.org/zh-CN/docs/Web/HTTP/CORS
3.解决办法
方法一：通过nginx将浏览器访问地址和请求地址统一
方法二：后端配置将预检请求允许跨域
13.解决登录跨域问题
本机调试采取方法二
在网关工程中添加配置类允许跨域
package com.hejiawang.gulimall.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.reactive.CorsConfigurationSource;
import org.springframework.web.cors.reactive.CorsWebFilter;
import org.springframework.web.cors.reactive.UrlBasedCorsConfigurationSource;
import org.springframework.web.server.ServerWebExchange;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
@Configuration
public class GulimallCorsConfiguration {
@Bean
public CorsWebFilter corsWebFilter(){
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
CorsConfiguration corsConfiguration = new CorsConfiguration();
// 1.配置跨域
corsConfiguration.addAllowedHeader("*");
corsConfiguration.addAllowedMethod("*");
corsConfiguration.setAllowedOrigins(Collections.singletonList("*"));
corsConfiguration.setAllowCredentials(true);
source.registerCorsConfiguration("/**",corsConfiguration);
return new CorsWebFilter(source);
}
}
将renren-fast后端跨域内容注释掉，使用我们自己配的
重启服务即可成功登录
14.初始化gulimall-product项目
1.网关配置product对应路由转发
- id: product_route
uri: lb://gulimall-product
predicates:
- Path=/api/product/**
filters:
- RewritePath=/api/?(?.*), /$\{segment}
2.在nacos上创建商品服务的命名空间
3.在nacos product命名空间下创建要管理的配置文件
4.商品服务客户端增加nacos配置中心相关配置
添加bootstrap文件及配置中心地址
spring.application.name=gulimall-product
spring.cloud.nacos.config.server-addr=127.0.0.1:8848
spring.cloud.nacos.config.namespace=a7d07264-e472-4466-9b28-e14caee4e0d7
添加注册发现注解
添加注册中心地址
启动服务看到product注册上来了
15.尝试访问
直接访问product可以返回数据
通过网关访问报错 http://localhost:88/api/product/category/list/tree
因为网关被拦截，优先顺序，将最模糊的路由放在最后重启
再次访问网关http://localhost:88/api/product/category/list/tree访问成功
16.前端工程中配置全路径到gateway，并且配置menu请求路径
<template>
<el-tree :data="data" :props="defaultProps" @node-click="handleNodeClick"></el-tree>
</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: {},
data() {
return {
data: [],
defaultProps: {
children: 'children',
label: 'label'
}
};
},
methods: {
handleNodeClick(data) {
console.log(data);
},
getMenus() {
this.dataListLoading = true
this.$http({
url: this.$http.adornUrl('/product/category/list/tree'),
method: 'get'
}).then(data=>{
console.log("成功获取到菜单数据...",data)
})
}
},
// 监听属性 类似于data概念
computed: {},
// 监控data中的数据变化
watch: {},
// 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>
请求测试返回数据
17.修改前端
<template>
<el-tree :data="menus" :props="defaultProps" @node-click="handleNodeClick"></el-tree>
</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: {},
data() {
return {
menus: [],
defaultProps: {
children: 'children',
label: 'name'
}
};
},
methods: {
handleNodeClick(data) {
console.log(data);
},
getMenus() {
this.dataListLoading = true
this.$http({
url: this.$http.adornUrl('/product/category/list/tree'),
method: 'get'
}).then(({data})=>{
console.log("成功获取到菜单数据...",data.data)
this.menus = data.data
})
}
},
// 监听属性 类似于data概念
computed: {},
// 监控data中的数据变化
watch: {},
// 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>
即可看到菜单显示出来
商品服务三级分类逻辑删除后端
1.CategoryController类
/**
* 删除
*/
@RequestMapping("/delete")
public R delete(@RequestBody Long[] catIds){
// 原始方法先注释
// categoryService.removeByIds(Arrays.asList(catIds));
// 1、检查当前删除的菜单，是否被其他地方引用到
categoryService.removeMenuByIds(Arrays.asList(catIds));
return R.ok();
}
2.CategoryServiceImpl类
@Override
public void removeMenuByIds(List<Long> asList) {
// TODO: 检查当前删除的菜单是否被引用，
baseMapper.deleteBatchIds(asList);
}
3.CategoryEntity类对对应字段加上@TableLogic
package com.hejiawang.gulimall.product.entity;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableLogic;
import com.baomidou.mybatisplus.annotation.TableName;
import java.io.Serializable;
import java.util.Date;
import java.util.List;
import lombok.Data;
/**
* 商品三级分类
*
* @author hejiawang
* @email [email protected]
* @date 2023-06-13 14:42:51
*/
@Data
@TableName("pms_category")
public class CategoryEntity implements Serializable {
private static final long serialVersionUID = 1L;
/**
* 分类id
*/
@TableId
private Long catId;
/**
* 分类名称
*/
private String name;
/**
* 父分类id
*/
private Long parentCid;
/**
* 层级
*/
private Integer catLevel;
/**
* 是否显示[0-不显示，1显示]
*/
@TableLogic(value = "1",delval = "0")
private Integer showStatus;
/**
* 排序
*/
private Integer sort;
/**
* 图标地址
*/
private String icon;
/**
* 计量单位
*/
private String productUnit;
/**
* 商品数量
*/
private Integer productCount;
@TableField(exist = false)
private List<CategoryEntity> children;
}
4.配置文件加上全局配置及
# MapperScan
# sql映射文件位置
mybatis-plus:
mapper-locations: classpath*:/mapper/**/*.xml
global-config:
db-config:
id-type: auto
#使用的地方相反可使用@TableLogic，全局默认配置
logic-delete-value: 1
logic-not-delete-value: 0
logging:
level:
com.hejiawang.gulimall: debug
5.测试接口
查询初始化数据
调用接口
结果
打印sql过程为update
6.前端修改
1.新增代码模板片段 vue.code,将模板粘贴进去
{
"Print to console": {
"prefix": "vue",
"body": [
"",
"$5",
"",
"",
"",
""
],
"description": "生成vue模板"
},
"http-get请求": {
"prefix": "httpget",
"body": [
"this.\\$http({",
"url: this.\\$http.adornUrl(''),",
"method: 'get',",
"params: this.\\$http.adornParams({})",
"}).then(({ data }) => {",
"})"
],
"description": "httpGET请求"
},
"http-post请求": {
"prefix": "httppost",
"body": [
"this.\\$http({",
"url: this.\\$http.adornUrl(''),",
"method: 'post',",
"data: this.\\$http.adornData(data, false)",
"}).then(({ data }) => { });"
],
"description": "httpPOST请求"
}
}
2.修改前端删除后展开父菜单并且刷新前端
<template>
<el-tree :data="menus" :props="defaultProps" :default-expanded-keys="expandedKey" node-key="catId" show-checkbox :expand-on-click-node="false">
<span class="custom-tree-node" slot-scope="{ node, data }">
<span>{{ node.label }}</span>
<span>
<el-button v-if="node.level <= 2" type="text" size="mini" @click="() => append(data)">
