三级分类删除——逻辑删除
后台处理
后台配置改变
首先需要修改后台配置
设置gateway网关路由
由于我们前端调用是通过网关调用的，首先要修改路由让前端可以正常访问其他模块的接口
设置application.yml
spring:
cloud:
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
- id: product_route
uri: lb://gulimall-product
predicates:
- Path=/api/product/**
filters:
- RewritePath=/api/(?<segment>.*),/$\{
segment}
- id: admin_route
uri: lb://renren-fast
predicates:
- Path=/api/**
filters:
- RewritePath=/api/(?<segment>.*),/renren-fast/$\{
segment}
nacos:
discovery:
server-addr: 123.57.234.28:8848
application:
name: gulimall-gateway
server:
port: 8070
增加对product模块的路由访问
设置renrenfast,nacos配置中心
renrenfast模块启动每次都会报错，是因为nacos配置中心没设置
在项目的resource下添加bootstrap.properties
spring.cloud.nacos.config.server-addr=123.57.234.28:8848
设置product模块mybatis-plus配置
可以查看myabtis-plus的官网，里面对逻辑删除有全局配置
application.yml
server:
port: 10001
spring:
datasource:
url: jdbc:mysql://123.57.235.28:3306/gulimall_pms?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=Asia/Shanghai
username:
password:
driver-class-name: com.mysql.jdbc.Driver
application:
name: gulimall-product
cloud:
nacos:
discovery:
server-addr: 123.57.234.18:8848
# MapperScan
#
mybatis-plus:
mapper-locations: classpath:/mapper/**/*.xml
global-config:
db-config:
id-type: auto
logic-delete-value: 1
logic-not-delete-value: 0
步骤2: 实体类字段上加上@TableLogic注解
如果删除标志和全局配置不同可以通过注解属性单独配置
如下
CategoryEntity.java
/**
* 是否显示[0-不显示，1显示]
*/
@TableLogic(value="1",delval = "0")
private Integer showStatus;
后台代码修改
修改批量删除接口
categoryController
/**
* 删除
*/
@RequestMapping("/delete")
//@RequiresPermissions("product:category:delete")
public R delete(@RequestBody Long[] catIds){
categoryService.removeMenus(Arrays.asList(catIds));
return R.ok();
}
categoryService
Integer removeMenus(Collection<? extends Serializable> idList);
categoryServiceImpl
@Override
public Integer removeMenus(Collection<? extends Serializable> idList) {
//TODO 如果有子分类就不删除
//逻辑删除
return baseMapper.deleteBatchIds(idList);
}
重启后台服务
前端改变
设置tree组件
引入tree组件的功能
<template>
<el-tree
:data="menus"
node-key="catId"
:props="defaultProps"
@node-click="handleNodeClick"
show-checkbox
:expand-on-click-node="false"
:default-expanded-keys="expandedKey"
>
<span class="custom-tree-node" slot-scope="{ node, data }">
<span>{
{
node.label }}</span>
<span>
<el-button
type="text"
size="mini"
@click="() => append(data)"
v-if="node.level <= 2"
>
添加下级分类
</el-button>
<el-button
type="text"
size="mini"
@click="() => remove(node, data)"
v-if="node.childNodes.length == 0"
>
删除
</el-button>
</span>
</span>
</el-tree>
</template>
调用后台方法联调
配置product模块日志输入
yml
logging:
level:
com.xfwang.gulimall.product: debug
方法和data数据配置
export default {
//import引入的组件需要注入到对象中才能使用
components: {
},
data() {
//这里存放数据
return {
menus: [],
expandedKey: [],
defaultProps: {
children: "child",
label: "name",
},
};
},
//监听属性 类似于data概念
computed: {
},
//监控data中的数据变化
watch: {
},
//方法集合
methods: {
handleNodeClick(data) {
console.log(data);
},
getDataList() {
this.dataListLoading = true;
this.$http({
url: this.$http.adornUrl("/product/category/list/tree"),
method: "get",
}).then(({
data }) => {
this.menus = data.data;
});
},
append(data) {
console.log(111);
},
remove(node, data) {
var ids = [data.catId];
this.$confirm(`是否删除【${
data.name}】菜单?`, "提示", {
confirmButtonText: "确定",
cancelButtonText: "取消",
type: "warning",
})
.then(() => {
this.$http({
url: this.$http.adornUrl("/product/category/delete"),
method: "post",
data: this.$http.adornData(ids, false),
}).then(({
data }) => {
this.$message({
message: "菜单删除成功",
type: "success",
});
//刷新出新的菜单
this.getDataList();
//设置需要默认展开的菜单
this.expandedKey = [node.parent.data.catId];
});
})
.catch(() => {
});
},
},
//生命周期 - 创建完成（可以访问当前this实例）
created() {
this.getDataList();
},
//生命周期 - 挂载完成（可以访问DOM元素）
mounted() {
},
};
