前言
在Element UI搭建首页导航和左侧菜单以及Mock.js和（组件通信）总线的运用博文中讲解了首页导航和左侧树形菜单的搭建，今天我们将通过前后端结合将左侧菜单数据变活，以及实现点击动态树右边展示相应内容。并实现对表格的分页模糊查询。
一、动态树的实现
后端mapper.xml,以及biz层都比较简单，这里就不过多讲解了
1.数据表
2.编写后端controller层
package com.ctb.ssm.controller;import com.ctb.ssm.model.Module;
import com.ctb.ssm.model.RoleModule;
import com.ctb.ssm.model.TreeNode;
import com.ctb.ssm.service.IModuleService;
import com.ctb.ssm.util.JsonResponseBody;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;import java.util.List;@Controller
@RequestMapping("/module")
public class ModuleController {@Autowiredprivate IModuleService moduleService;@RequestMapping("/queryRootNode")@ResponseBodypublic JsonResponseBody<List<Module>> queryRootNode(){try {List<Module> modules = moduleService.queryRootNode(-1);return new JsonResponseBody<>("OK",true,0,modules);} catch (Exception e) {e.printStackTrace();return new JsonResponseBody<>("初始化首页菜单错误",false,0,null);}}}
3.定义前端发送请求路径
api/action.js
'SYSTEM_MENUS': '/module/queryRootNode', //左侧菜单4.前端左侧动态树的编写
4.1.发送请求获取数据
let url = this.axios.urls.SYSTEM_MENUS;this.axios.get(url, {}).then(r => {console.log(r);this.menus = r.data.rows;}).catch(e => {})4.2.遍历左侧菜单
<el-submenu v-for="m in menus" :index="'idx_'+m.id" :key="'key_'+m.id"><template slot="title"><i class="m.icon"></i><span>{{m.text}}</span></template><el-menu-item v-for="m2 in m.modules" :index="m2.url" :key="'key_'+m2.id"><i class="m2.icon"></i><span>{{m2.text}}</span></el-menu-item></el-submenu>效果展示
5.实现左侧菜单点击展示右边内容
先编写两个组件测试效果，也为下面内容进行铺垫
5.1.定义组件
AddBook
<template><h1>书籍新增</h1>
</template><script>
</script><style>
</style>
BookList
<template><h1>书籍管理</h1>
</template><script>
</script><style>
</style>
5.2.定义组件与路由的对应关系
import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'import AppMain from '@/components/AppMain'
import LeftNav from '@/components/LeftNav'
import TopNav from '@/components/TopNav'import Login from '@/views/Login'
import Register from '@/views/Register'
import AddBook from '@/views/book/AddBook'
import BookList from '@/views//book/BookList'Vue.use(Router)export default new Router({routes: [{path: '/',name: 'Login',component: Login},{path: '/Register',name: 'Register',component: Register}, {path: '/AppMain',name: 'AppMain',component: AppMain,children: [{path: '/LeftNav',name: 'LeftNav',component: LeftNav}, {path: '/TopNav',name: 'TopNav',component: TopNav},{path: '/book/AddBook',name: 'AddBook',component: AddBook}, {path: '/book/BookList',name: 'BookList',component: BookList}]}]
})
5.3.渲染组件内容
在AppMain.vue中心区域显示内容处改为以下内容：
<router-view></router-view>5.4.通过动态路由跳转为当前项内容
router :default-active="$route.path"
效果展示：
二、表格分页模糊查询的实现
1.数据表
2.后端分页模糊查询的实现
这里也就只展示controller层了，有需要的评论区留言或私聊
@RequestMapping("/queryBookPager")@ResponseBodypublic JsonResponseBody<List<Book>> queryBookPager(Book book, HttpServletRequest req){try {PageBean pageBean=new PageBean();pageBean.setRequest(req);List<Book> books = bookService.queryBookPager(book, pageBean);return new JsonResponseBody<>("OK",true,pageBean.getTotal(),books);} catch (Exception e) {e.printStackTrace();return new JsonResponseBody<>("分页查询书本失败",false,0,null);}}3.编写书籍管理请求路径
'SYSTEM_BookList': '/book/queryBookPager', //书籍管理---分页模糊查询4.编写书籍管理前端
BookList.vue
<template><div class="books" style="padding: 20px;"><!-- 1.搜索框 --><el-form :inline="true" class="demo-form-inline"><el-form-item label="书籍名称"><el-input v-model="bookname" placeholder="书籍名称"></el-input></el-form-item><el-form-item><el-button type="primary" @click="onSubmit">搜索</el-button></el-form-item></el-form><!-- 2.数据表格 --><el-table :data="tableData" stripe style="width: 100%"><el-table-column prop="id" label="书籍编号" width="180"></el-table-column><el-table-column prop="bookname" label="书籍名称" width="180"></el-table-column><el-table-column prop="price" label="书籍价格"></el-table-column><el-table-column prop="booktype" label="书籍类型"></el-table-column></el-table><!-- 3.分页条 --><div class="block" style="padding: 20px;"><el-pagination @size-change="handleSizeChange" @current-change="handleCurrentChange" :current-page="page":page-sizes="[10, 20, 30, 40]" :page-size="rows" layout="total, sizes, prev, pager, next, jumper":total="total"></el-pagination></div></div></template><script>export default {data() {return {bookname: '',tableData: [],rows:10,page:1,total:0}},methods: {// 定义一个查询的方法，方便调用减少代码冗余query(params) {// 向后台请求数据的访问路径let url = this.axios.urls.SYSTEM_BookList;this.axios.get(url, {params: params}).then(r => {console.log(r);this.tableData = r.data.rows;this.total = r.data.total;}).catch(e => {})},onSubmit() {let params = {bookname: this.bookname,}// 调用查询方法this.query(params);},handleSizeChange(r) { //当页大小发生变化// 输出查看console.log("当前页大小:"+r);let params = {bookname: this.bookname,rows:r,page:this.page}// 调用查询方法this.query(params);},handleCurrentChange(p) { //当前页页码发生变化// 输出查看console.log("当前页码:"+p);let params = {bookname: this.bookname,page:p,rows:this.rows}// 调用查询方法this.query(params);}},created() {// 调用查询方法this.query({});}}
</script><style>
</style>
效果展示
