    在这里插入图片描述

    二、 确定需求方案

    后台进行栏目和文章的编辑，编辑完后前台展示。

    三、整体架构设计

    1. 前端基于Vue+ElementUi，使用WebStorm编辑器；
    2. 后端基于Springboot+SpringSecurity+MyBatisPlus+JWT+Redis实现，使用 IDEA 编辑器；
    3. 数据传输格式：JSON；
    4. 数据库：mysql

    三、编码实现 （关键代码）

    1、前端Vue代码 - main.js

    import Vue from 'vue'
import App from './App.vue'
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
import router from './router'
import store from './store'
import {initMenu} from  '/src/utils/menus'
import {getUserInfo} from  '/src/utils/http'
import 'font-awesome/css/font-awesome.css'
import mavonEditor from 'mavon-editor'
import 'mavon-editor/dist/css/index.css';

Vue.config.productionTip = false

Vue.use(ElementUI);
Vue.use(mavonEditor)

router.beforeEach((to,from,next)=>{
	if(window.sessionStorage.getItem("token")){
		initMenu(router,store);
		console.log(router);
		if(!window.sessionStorage.getItem('user')){
			return getUserInfo().then(res=>{
				window.sessionStorage.setItem('user',JSON.stringify(res));
				next();
			})
		}
		next();
	}else{
		if(to.path=='/'){
			next();
		}else{
			next('/?redirect='+to.path);
		}
	}
})

new Vue({
	el: '#app',
	router,
	store,
	render: h => h(App),
}).$mount('#app')

    2、前端JS代码 - 动态路由

    import {
	getNav
} from './http.js'

export const initMenu = (router, store) => {
	if (store.state.routes.length > 0) {
		return;
	}

	getNav().then(data => {
		if (data) {
			let fmtRoutes = formatRoutes(data);
			//动态路由
			router.addRoutes(fmtRoutes);
			router.options.routes = fmtRoutes;
			//数据存入vuex
			store.commit('initRoutes',fmtRoutes);
		}
	})

}

export const dealPath=(path=>{
	return ((path.split('/')).length-1)>1?path.substring(path.indexOf("/"),path.lastIndexOf("/")):path.substring(path.indexOf("/"),path.length)
})


export const formatRoutes = (routes) => {
	let fmtRoutes = [];
	routes.forEach(router=>{
		let{
			path,
			component,
			name,
			iconCls,
			children
		} = router;
		if(children&&children instanceof Array){
			children = formatRoutes(children);
		}
		let fmtRouter = {
			path:path,
			name:name,
			iconCls:iconCls,
			children:children,
			component:()=>import(`../views${dealPath(path)}/${component}.vue`),
			// component:component
		}
		fmtRoutes.push(fmtRouter);
	})
	return fmtRoutes;
}

    4、后端Java代码 swagger配置
