Springboot運(yùn)用vue+echarts前后端交互實(shí)現(xiàn)動(dòng)態(tài)圓環(huán)圖

更新時(shí)間：2021年06月15日 10:41:41 作者：沉默著忍受

我們做項(xiàng)目的時(shí)候，常常需要一些統(tǒng)計(jì)圖來(lái)展示我們的數(shù)據(jù)，作為web開(kāi)發(fā)人員，會(huì)實(shí)現(xiàn)統(tǒng)計(jì)圖是我們必會(huì)的技能。我將帶大家來(lái)實(shí)現(xiàn)動(dòng)態(tài)餅圖的實(shí)現(xiàn)，感興趣的可以了解一下

前言

一、環(huán)境配置

1.1 安裝acharts

//npm也一樣
cnpm install echarts --save

1.2 全局引用

main.js中配置

//引入 echarts
import echarts from 'echarts'
//注冊(cè)組件
Vue.prototype.$echarts = echarts

全局注冊(cè)好組件之后就讓我們進(jìn)入正題吧，第一步先繪制圓環(huán)圖吧。先上結(jié)果圖：

在這里插入圖片描述

二、圓環(huán)圖前端實(shí)現(xiàn)

2.1 先在vue頁(yè)面添加渲染盒子

<template>
  <div class="test2" style="width:600px;height:400px;">
      <div id="myChart" style="width:100%;height:278px;float:left;"></div>
  </div>
</template>

2.2 前端邏輯實(shí)現(xiàn)部分

引入echart

import * as echarts from 'echarts'

注意：這里有一個(gè)大坑，如果你安裝的是高版本的echarts,一定要按我這個(gè)來(lái)，import echarts from 'echarts'網(wǎng)上很多人都這么分享會(huì)發(fā)生init函數(shù)初始化錯(cuò)誤

<script>
     import * as echarts from 'echarts'
     export default {
       name: 'test2',
       data () {
         return {
         queryInfo: {
         query: "",
         pageNum: 1,
         pageSize: 4,//后端請(qǐng)求的數(shù)據(jù)類(lèi)別4個(gè)，如果你有多個(gè)，就更改這個(gè)參數(shù)
       },
       queryInfof: {
         query: "",
         pageNum: 1,
         pageSize: 100,
       },
           myChart: '',
           opinionData2: [

           ]
         }
       },

          this.drawLine();

       },

      });
      if (res.flag != "success") {
        return this.$message.error("該數(shù)據(jù)獲取失?。。?！");
      }

      console.log(res.flag)
       this.opinionData2 = res.opinionData2; // 將返回?cái)?shù)據(jù)賦值*/
           this.myChart = echarts.init(document.getElementById('myChart'))
           this.myChart.setOption({
             title: {
               text: '網(wǎng)絡(luò)日志異常流量分析', // 主標(biāo)題

                   },
                   color: function (params) {
                     // 自定義顏色
                     var colorList = ['#1FC48D', 'red', '#6DC8EC', '#3F8FFF']
                     return colorList[params.dataIndex]
                   }
                 },
                 data: this.opinionData2
               }
             ]
           })
         },
       }
     }

表數(shù)據(jù)

在這里插入圖片描述

3.2 后臺(tái)代碼的編寫(xiě)

3.2.1 在bean包下創(chuàng)建QueryInfo類(lèi)

該類(lèi)實(shí)現(xiàn)得到前端請(qǐng)求的數(shù)據(jù)條數(shù)。相當(dāng)于分頁(yè)功能。

public class QueryInfo {
    private String query;
    private int pageNum=1;
    private int pageSize=1;

    public QueryInfo() {
    }

    public QueryInfo(String query, int pageNum, int pageSize) {
        this.query = query;
        this.pageNum = pageNum;
        this.pageSize = pageSize;
    }

    public String getQuery() {
        return query;
    }

    public int getPageNum() {
        return pageNum;
    }

    public int getPageSize() {
        return pageSize;
    }

    public void setQuery(String query) {
        this.query = query;
    }

    public void setPageNum(int pageNum) {
        this.pageNum = pageNum;
    }

    public void setPageSize(int pageSize) {
        this.pageSize = pageSize;
    }

    @Override
    public String toString() {
        return "QueryInfo{" +
                "query='" + query + '\'' +
                ", pageNum=" + pageNum +
                ", pageSize=" + pageSize +
                '}';
    }
}

3.2.2 在bean包下創(chuàng)建Showdate類(lèi)

public class Showdate {
    private  String name;
    private  String itemStyle;
    private  int value;


    public Showdate() {

    }

    public Showdate(String name, String itemStyle, int value) {
        this.name = name;
        this.itemStyle = itemStyle;
        this.value = value;
    }

    public String getName() {
        return name;
    }

    public void setName1(String name) {
        this.name= name;
    }

    public String getItemStyle() {
        return itemStyle;
    }

    public void setItemStyle(String itemStyle) {
        this.itemStyle = itemStyle;
    }

    public int getValue() {
        return value;
    }

    public void setValue(int value) {
        this.value = value;
    }

    @Override
    public String toString() {
        return "Showdate{" +
                "name='" + name + '\'' +
                ", itemStyle='" + itemStyle + '\'' +
                ", value=" + value +
                '}';
    }
}

3.2.3 在resources下創(chuàng)建Mapper

1.在Mapper中創(chuàng)建ShowDataMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper  PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.naughty.userlogin02.dao.ShowdateDao">


    <select id="getAlldate" resultType="com.naughty.userlogin02.bean.Showdate">
        SELECT * FROM date1
        <if test="name!=null ">
            WHERE name like #{name}
        </if>
        LIMIT #{pageStart},#{pageSize}
    </select>

    <update id="updatenew">
        UPDATE date1 SET value = #{count} WHERE name = #{name}
    </update>


</mapper>

2.在resources下創(chuàng)建application.yml用于配置數(shù)據(jù)庫(kù)和端口號(hào)

# mysql
spring:
  datasource:
    #MySQL配置
    driverClassName:  com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/weblog?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=UTC
    username: root
    password: root

mybatis:
  mapper-locations: classpath:mapper/*.xml
  type-aliases-package: com.example.demo.model
server:
  port: 9000

3.2.4 在Dao下創(chuàng)建ShowdateDao

里面有兩個(gè)接口，如果你需要操作數(shù)據(jù)庫(kù)，就需要在ShowdateDao中編寫(xiě)接口方法；
在ShowDataMapper.xml中編寫(xiě)sql語(yǔ)句。
我這里實(shí)現(xiàn)了修改和查找；

import com.naughty.userlogin02.bean.Showdate;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;

import java.util.List;
@Repository
public interface ShowdateDao {

    public List<Showdate> getAlldate(@Param("name") String name, @Param("pageStart") int pageStart, @Param("pageSize") int pageSize);

    public int updatenew(String name, int count);
}

3.2.5 在Controller下創(chuàng)建ShowdateController

在ShowdateController中要注解使用空間

   @Autowired
    ShowdateDao showdateDao;//你需要傳給前端的數(shù)據(jù)庫(kù)表
    @Autowired
    FlowDao flowDao;//你的數(shù)據(jù)來(lái)源的效果數(shù)據(jù)庫(kù)表

package com.naughty.userlogin02.controller;

import com.alibaba.fastjson.JSON;
import com.naughty.userlogin02.bean.*;
import com.naughty.userlogin02.dao.CheckDao;
import com.naughty.userlogin02.dao.FlowDao;
import com.naughty.userlogin02.dao.SafeDao;
import com.naughty.userlogin02.dao.ShowdateDao;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.HashMap;
import java.util.List;
import java.util.Stack;

@RestController
public class ShowdateController {

    @Autowired
    ShowdateDao showdateDao;
    @Autowired
    FlowDao flowDao;
//前臺(tái)刷新日志數(shù)據(jù)
    @CrossOrigin
    @RequestMapping("/alldate")//前端請(qǐng)求通道
    public String getAlldateList(QueryInfo queryInfo){
        System.out.println(queryInfo);
        int pageStart = (queryInfo.getPageNum()-1)*queryInfo.getPageSize();
        List<Showdate> dates = showdateDao.getAlldate("%"+queryInfo.getQuery()+"%",pageStart,queryInfo.getPageSize());
   
      for(int i =0;i<dates.size();i++){
          System.out.println(dates.get(i).toString());
      }
        //校驗(yàn)
        //封裝校驗(yàn)后的流量日志
        HashMap<String, Object> res = new HashMap<>();
        res.put("flag","success");
        res.put("opinionData2",dates );
        String date_json= JSON.toJSONString(res);
        System.out.println(date_json.toString());
        return date_json;
    }

//數(shù)據(jù)庫(kù)數(shù)據(jù)來(lái)源的實(shí)現(xiàn)方法，就是改變數(shù)據(jù)庫(kù)表Date1中得數(shù)據(jù)
    @RequestMapping("/getupdata")
    public String updateDate(QueryInfo queryInfo){

        String s = "流量日志異常";
        String s1 ="審計(jì)url異常";
        String s2 ="威脅攻擊日志";
        String s3 ="正常網(wǎng)絡(luò)日志";
        /*int count = getUserList(queryInfo);
        int count1 =getChickList(queryInfo);  //四個(gè)方法需要你自己根據(jù)具體業(yè)務(wù)實(shí)現(xiàn)
        int count2 =getSafeDate(queryInfo);
        int count3 =allBlognum(queryInfo)-(count+count1+count2);*/
        showdateDao.updatenew(s,count);
        showdateDao.updatenew(s1,count1);
        showdateDao.updatenew(s2,count2);
        int i= showdateDao.updatenew(s3,count3);
        System.out.println("異常類(lèi)型:"+s);
        System.out.println("異常日志數(shù)量:"+count);
        String str = i >0?"success":"error";
        return str;
    }

}

3.2.6 修改前端接口

Js全部代碼：

   <script>
     import * as echarts from 'echarts'
     export default {
       name: 'test2',
       data () {
         return {
         queryInfo: {
         query: "",
         pageNum: 1,
         pageSize: 4,
       },
       queryInfof: {
         query: "",
         pageNum: 1,
         pageSize: 100,
       },
           myChart: '',
           opinionData2: [

           ]
         }
       },
       mounted: function () {
          this.drawLine();

       },
       created() {
         this.getdateList();  //每次進(jìn)入頁(yè)面刷新數(shù)據(jù)庫(kù)數(shù)據(jù)實(shí)現(xiàn)動(dòng)態(tài)數(shù)據(jù)綁定
      },
       methods: {
          async  drawLine () {
              // 調(diào)用post請(qǐng)求，獲得后臺(tái)數(shù)據(jù)庫(kù)的數(shù)值
      const { data: res } = await this.$http.get("alldate", {
        params: this.queryInfo
      });
      if (res.flag != "success") {
        return this.$message.error("該數(shù)據(jù)獲取失敗?。。?);
      }

      console.log(res.flag)
       this.opinionData2 = res.opinionData2; // 將返回?cái)?shù)據(jù)賦值
           this.myChart = echarts.init(document.getElementById('myChart'))
           this.myChart.setOption({
