一、导言

1、引言

2、目的

二、动态树

1、后端数据接口定义

Controller层

    @RequestMapping("/queryRootNode")
    @ResponseBody
    public 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);
        }
    }

2、前端导航菜单绑定

2.1、页面布局

菜单结构

<!--  添加动态路由：router :default-active="$route.path"-->
  <el-menu router :default-active="$route.path" default-active="2" class="el-menu-vertical-demo"
           background-color="#334157"
           text-color="#fff" active-text-color="#ffd04b" :collapse="collapsed">
    <!-- <el-menu default-active="2" :collapse="collapsed" collapse-transition router :default-active="$route.path" unique-opened class="el-menu-vertical-demo" background-color="#334157" text-color="#fff" active-text-color="#ffd04b"> -->
    <div class="logobox">
      <img class="logoimg" src="../assets/img/logo.png" alt="">
    </div>
    <el-submenu v-for="m in menus" :index="'index_'+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>
  </el-menu>

vue+element的el-menu组件实现路由跳转及当前项的设置

router :default-active="$route.path"

2.2、数据绑定

  created() {
    this.$root.Bus.$on('sjm', v => {
      this.collapsed = v;
    });
//树形菜单
    //后台访问地址
    let url = this.axios.urls.SYSTEM_MENUS;
    this.axios.get(url, {}).then(r => {
//利用数组接受后台的数据
      this.menus = r.data.rows;
    }).catch(error => {

    })

  }

2.3、路由绑定页面编写

路由绑定

跳转页面编写

效果

三、数据表格及分页

1、后端数据接口定义

package com.zking.ssm.controller;

import com.zking.ssm.model.Book;
import com.zking.ssm.service.IBookService;
import com.zking.ssm.util.JsonResponseBody;
import com.zking.ssm.util.PageBean;
import com.zking.ssm.vo.BookFileVo;
import org.apache.commons.io.IOUtils;
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 org.springframework.web.multipart.MultipartFile;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.URLEncoder;
import java.util.List;
import java.util.Map;

@Controller
@RequestMapping("/book")
public class BookController {

    @Autowired
    private IBookService bookService;

    @RequestMapping("/queryBookPager")
    @ResponseBody
    public 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);
        }
    }

 
}

2、前端

<template>
  <div class="Book" style="padding: 30px;">
    <!-- 输入框搜索 -->
    <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" plain @click="onSubmit">查询</el-button>
      </el-form-item>
    </el-form>
    <!-- 书籍的书籍表格 -->
    <el-table :data="tableData" style="width: 100%">
      <el-table-column prop="id" label="书籍ID"></el-table-column>
      <el-table-column prop="bookname" label="书籍名称"></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>
    <!-- 分页 -->
    <div class="block" style="padding: 20px;">
      <el-pagination @size-change="handleSizeChange" @current-change="handleCurrentChange" :current-page="page"
                     background :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,
      total: 0,
      page: 1
    }
  },
  methods: {
    handleSizeChange(r) {
      //当页大小发生变化
      let params = {
        bookname: this.bookname,
        rows: r,
        page: this.page
      }
      this.query(params);
    },
    handleCurrentChange(p) {
      //当前页码大小发生变化
      let params = {
        bookname: this.bookname,
        rows: this.rows,
        // 分页
        page: p
      }
      // console.log(params)
      this.query(params);
    },
    query(params) {
      //获取后台请求书籍数据的地址
      let url = this.axios.urls.SYSTEM_BOOKLIST;
      this.axios.get(url, {
        params: params
      }).then(d => {
        this.tableData = d.data.rows;
        this.total = d.data.total;
      }).catch(e => {
      });
    },
    onSubmit() {
      let params = {
        bookname: this.bookname
      }
      console.log(params)
      this.query(params);
      this.bookname = ''
    }
  },
  created() {
    this.query({})
  }
}
</script>

<style>
</style>
