向数据库gulimall_pms中的表pms_category导入数据,脚本如下:
DROP TABLE IF EXISTS `pms_category`;
CREATE TABLE `pms_category` (
`cat_id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '分类id',
`name` char(50) DEFAULT NULL COMMENT '分类名称',
`parent_cid` bigint(20) DEFAULT NULL COMMENT '父分类id',
`cat_level` int(11) DEFAULT NULL COMMENT '层级',
`show_status` tinyint(4) DEFAULT NULL COMMENT '是否显示[0-不显示,1显示]',
`sort` int(11) DEFAULT NULL COMMENT '排序',
`icon` char(255) DEFAULT NULL COMMENT '图标地址',
`product_unit` char(50) DEFAULT NULL COMMENT '计量单位',
`product_count` int(11) DEFAULT NULL COMMENT '商品数量',
PRIMARY KEY (`cat_id`)
) ENGINE=InnoDB AUTO_INCREMENT=1433 DEFAULT CHARSET=utf8mb4 COMMENT='商品三级分类';
## 2、后端的代码实现
编辑我们product 模块
### 2.1 CategoryController
```java
@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> entities = categoryService.listWithTree();
return R.ok().put("data", entities);
}
/**
* 商品三级分类
*
* @author fangsheng
* @email [email protected]
* @date 2022-04-10 22:48:10
*/
public interface CategoryService extends IService<CategoryEntity> {
PageUtils queryPage(Map<String, Object> params);
List<CategoryEntity> listWithTree();
}
给CategoryEntity 加入属性
@JsonInclude(JsonInclude.Include.NON_EMPTY)
@TableField(exist=false)
private List<CategoryEntity> children;

运行主启动可能会报nacos 连接的错误,因为我之前在common中引入了配置中心,但是yml 文件没有配置
新建一个bootstrap.properties文件
spring.cloud.nacos.config.server-addr=119.3.105.108:8848
然后在启动 localhost:10000/product/category/list/tree
启动renren-fast后端系统在启动renren-fast-vue (npm run dev)的前端系统
给商品系统添加菜单
renren-fast引入common并且配置对应的配置中心和注册中心的地址

主启动
@EnableDiscoveryClient //添加开启注解
@SpringBootApplication
public class RenrenApplication {
public static void main(String[] args) {
SpringApplication.run(RenrenApplication.class, args);
}
}
如果启动报错,无法来连接上配置中心,新建一个bootstrap.properties文件将配置中心的配置放入进去
如果报错spring boot和spring cloud的版本不兼容就升级spring boot的版本

让其通过网关转发到renren-fast服务

先启动gateway
在启动renren-fast
最后启动前端
如果报错 503 则需要在gateway的服务中添加以下的依赖
<dependency>
<groupId>org.springframework.cloudgroupId>
<artifactId>spring-cloud-starter-loadbalancerartifactId>
dependency>
我的版本:springboot2.6.6 springcloud2021.0.1 nacos1.2.1 springcloud-alibaba 2.2.1
第一、首先解释下503错误的原因:
Spring Cloud 2020.0.0版本之前会自动引入Netflix Ribbon依赖,Netflix Ribbon功能跟loadbalancer一样,因Netflix公司停止维护Ribbon后, 在Spring Cloud 2020.0.0版本之后Spring使用loadbalancer替代了Ribbon, 但是loadbalancer依赖需要手动引入. 所以如果你使用的Spring Cloud版本是2020.0.0或更高的版本, 添加loadbalancer依赖即可解决503的问题;
**跨域:**指的是浏览器不能执行其他网站的脚本。它是由浏览器的同源策略造成的,是
浏览器对 javascript 施加的安全限制。
• 同源策略:是指协议,域名,端口都要相同,其中有一个不同都会产生跨域;
1、添加响应头
• Access-Control-Allow-Origin:支持哪些来源的请求跨域
• Access-Control-Allow-Methods:支持哪些方法跨域
• Access-Control-Allow-Credentials:跨域请求默认不包含cookie,设置为true可以包含 cookie
• Access-Control-Expose-Headers:跨域请求暴露的字段
• CORS请求时,XMLHttpRequest对象的getResponseHeader()方法只能拿到6个基本字段:
Cache-Control、Content-Language、Content-Type、Expires、Last-Modified、Pragma。如
果想拿到其他字段,就必须在Access-Control-Expose-Headers里面指定。
• Access-Control-Max-Age:表明该响应的有效时间为多少秒。在有效时间内,浏览器无 须为同一请求再次发起预检请求。请注意,浏览器自身维护了一个最大有效时间,如果 该首部字段的值超过了最大有效时间,将不会生效。
5.1 在gateway服务新建包config 并编写配置类
package com.atguigu.gulimall.gateway.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.CorsWebFilter;
import org.springframework.web.cors.reactive.UrlBasedCorsConfigurationSource;
/**
* @创建人: 放生
* @创建时间: 2022/4/15
* @描述:
*/
@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.addAllowedOrigin("*");
corsConfiguration.setAllowCredentials(true);
source.registerCorsConfiguration("/**",corsConfiguration);
return new CorsWebFilter(source);
}
}
注视掉renren-fast原有的跨域配置类
5.3 重新启动gateway renren-fast 服务
获取商品的数据是请求的product的服务,那么接下来配置商品服务到网关
1.1 确保之前已经在product服务引入了common模块,而common 模块的pom 引入了注册中心和配置中心
2.2 product 服务新建bootstrap.properties文件配置配置中心,并写服务名,然后在ymal 文件配置注册中心
bootstrap.properties:
# bootstrap.properties (暂时当前的命名空间下没有任何yaml文件)

我们利用的是 mybatis-plus 的逻辑删除功能,就是将一个状态的字段通过0 和 1 来标识是否删除
可以参考mybatis-plus的官网
mybatis-plus:
mapper-locations: classpath:/mapper/**/*.xml
global-config:
db-config:
id-type: auto
logic-delete-value: 1
logic-not-delete-value: 0
/**
* 是否显示[0-不显示,1显示]
*/
@TableLogic(value = "1",delval = "0")
private Integer showStatus;
/**
* 删除
*/
@RequestMapping("/delete")
public R delete(@RequestBody Long[] catIds){
categoryService.removeByIds(Arrays.asList(catIds));
return R.ok();
}
删除细化,主要考虑以下几点,删除是提示确认按钮,删除后提示删除成功或则失败,然后删除后对应的父节点要展开

1、拖拽功能也是Element-ui 组件提供的的,只需要配置draggable的相关属性以及定义对应的方法即可
draggable: true 表示开启拖拽功能 默认是关闭的,allowDrop()方法是做是否允许拖拽到指定位置的方法
<el-tree
:data="menus"
:props="defaultProps"
:expand-on-click-node="false"
show-checkbox
node-key="catId"
:default-expanded-keys="expandedKey"
:draggable="draggable"
:allow-drop="allowDrop"
ref="menuTree"
>
allowDrop(draggingNode, dropNode, type) {
//1、被拖动的当前节点以及所在的父节点总层数不能大于3
//1)、被拖动的当前节点总层数
console.log("allowDrop:", draggingNode, dropNode, type);
//
this.countNodeLevel(draggingNode);
//当前正在拖动的节点+父节点所在的深度不大于3即可
let deep = Math.abs(this.maxLevel - draggingNode.level) + 1;
console.log("深度:", deep);
// this.maxLevel
if (type == "inner") {
// console.log(
// `this.maxLevel:${this.maxLevel};draggingNode.data.catLevel:${draggingNode.data.catLevel};dropNode.level:${dropNode.level}`
// );
return deep + dropNode.level <= 3;
} else {
return deep + dropNode.parent.level <= 3;
}
},
countNodeLevel(node) {
//找到所有子节点,求出最大深度
if (node.childNodes != null && node.childNodes.length > 0) {
for (let i = 0; i < node.childNodes.length; i++) {
if (node.childNodes[i].level > this.maxLevel) {
this.maxLevel = node.childNodes[i].level;
}
this.countNodeLevel(node.childNodes[i]);
}
}
},
要获取我们拖拽后的数据,也利用组件提供的方法@node-drop获取结果,并需要自己去做相关的业务逻辑,因为拖拽后循序发生了变化我们需要重新排序,然后把整个结果集合传给后端(但是不可能没拖动一次就向后端提交一次,这样太频繁了,我们最终是点击按钮开启拖拽,在给个按钮提交才向后端提交数据)
@node-drop=handleDrop
handleDrop(draggingNode, dropNode, dropType, ev) {
console.log("handleDrop: ", draggingNode, dropNode, dropType);
//1、当前节点最新的父节点id
let pCid = 0;
let siblings = null;
if (dropType == "before" || dropType == "after") {
pCid =
dropNode.parent.data.catId == undefined
? 0
: dropNode.parent.data.catId;
siblings = dropNode.parent.childNodes;
} else {
pCid = dropNode.data.catId;
siblings = dropNode.childNodes;
}
this.pCid.push(pCid);
//2、当前拖拽节点的最新顺序,
for (let i = 0; i < siblings.length; i++) {
if (siblings[i].data.catId == draggingNode.data.catId) {
//如果遍历的是当前正在拖拽的节点
let catLevel = draggingNode.level;
if (siblings[i].level != draggingNode.level) {
//当前节点的层级发生变化
catLevel = siblings[i].level;
//修改他子节点的层级
this.updateChildNodeLevel(siblings[i]);
}
this.updateNodes.push({
catId: siblings[i].data.catId,
sort: i,
parentCid: pCid,
catLevel: catLevel
});
} else {
this.updateNodes.push({ catId: siblings[i].data.catId, sort: i });
}
}
//3、当前拖拽节点的最新层级
console.log("updateNodes", this.updateNodes);
},
updateChildNodeLevel(node) {
if (node.childNodes.length > 0) {
for (let i = 0; i < node.childNodes.length; i++) {
var cNode = node.childNodes[i].data;
this.updateNodes.push({
catId: cNode.catId,
catLevel: node.childNodes[i].level
});
this.updateChildNodeLevel(node.childNodes[i]);
}
}
},
只需要在product模块的categoryController的类中新增以下方法即可
@RequestMapping("/update/sort")
//@RequiresPermissions("product:category:update")
public R updateSort(@RequestBody CategoryEntity[] category){
categoryService.updateBatchById(Arrays.asList(category));
return R.ok();
}
下一章节统一写前端保存的方法,向后端提交数据
1、添加拖拽功能开启按钮和批量修改按钮
<el-switch v-model="draggable" active-text="开启拖拽" inactive-text="关闭拖拽">el-switch>
<el-button v-if="draggable" @click="batchSave">批量保存el-button>
2、批量提交
batchSave() {
this.$http({
url: this.$http.adornUrl("/product/category/update/sort"),
method: "post",
data: this.$http.adornData(this.updateNodes, false)
}).then(({ data }) => {
this.$message({
message: "菜单顺序等修改成功",
type: "success"
});
//刷新出新的菜单
this.getMenus();
//设置需要默认展开的菜单
this.expandedKey = this.pCid;
this.updateNodes = [];
this.maxLevel = 0;
// this.pCid = 0;
});
},
<el-button type="danger" @click="batchDelete">批量删除el-button>
要获取主键中所有选中的数据,然后提交给后端
batchDelete() {
let catIds = [];
let checkedNodes = this.$refs.menuTree.getCheckedNodes();
console.log("被选中的元素", checkedNodes);
for (let i = 0; i < checkedNodes.length; i++) {
catIds.push(checkedNodes[i].catId);
}
this.$confirm(`是否批量删除【${catIds}】菜单?`, "提示", {
confirmButtonText: "确定",
cancelButtonText: "取消",
type: "warning"
})
.then(() => {
this.$http({
url: this.$http.adornUrl("/product/category/delete"),

data: this.$http.adornData(catIds, false)

其实代码生成器不仅仅只生成了后端代码,简单的curd的前端代码也是有生成的,也可以用
/**
* 是否有权限
* @param {*} key
*/
export function isAuth (key) {
// return JSON.parse(sessionStorage.getItem('permissions') || '[]').indexOf(key) !== -1 || false
// 让它固定返回为 true
return true
}
基本的增删改查是ok 的
build > webpack.base.conf.js 中的createLintingRule 的方法内容注释掉
