前言我们做项目的时候,常常需要一些统计图来展示我们的数据,作为web开发人员,会实现统计图是我们必会的技能。我将带大家来实现动态饼图的实现 一、环境配置1.1 安装acharts//npm也一样 cnpm install echarts --save 1.2 全局引用main.js中配置 //引入 echarts import echarts from 'echarts' //注册组件 Vue.prototype.$echarts = echarts 全局注册好组件之后就让我们进入正题吧,第一步先绘制圆环图吧。先上结果图: 二、圆环图前端实现2.1 先在vue页面添加渲染盒子<template> <div class="test2" style="width:600px;height:400px;"> <div id="myChart" style="width:100%;height:278px;float:left;"></div> </div> </template> 2.2 前端逻辑实现部分引入echart import * as echarts from 'echarts' 注意:这里有一个大坑,如果你安装的是高版本的echarts,一定要按我这个来,import echarts from 'echarts'网上很多人都这么分享会发生init函数初始化错误 <script> import * as echarts from 'echarts' export default { name: 'test2', data () { return { queryInfo: { query: "", pageNum: 1, pageSize: 4,//后端请求的数据类别4个,如果你有多个,就更改这个参数 }, queryInfof: { query: "", pageNum: 1, pageSize: 100, }, myChart: '', opinionData2: [ {"itemStyle":"#3F8FFF","name":"威胁攻击日志","value":200}, {"itemStyle":"#6DC8EC","name":"审计url异常","value":388}, {"itemStyle":"#1FC48D","name":"正常网络日志","value":5287}, {"itemStyle":"red","name":"流量日志异常","value":320} ] } }, mounted: function () { this.drawLine(); }, methods: { async drawLine () { // 调用post请求 /* const { data: res } = await this.$http.get("alldate", { params: this.queryInfo }); if (res.flag != "success") { return this.$message.error("该数据获取失败!!!"); } console.log(res.flag) this.opinionData2 = res.opinionData2; // 将返回数据赋值*/ this.myChart = echarts.init(document.getElementById('myChart')) this.myChart.setOption({ title: { text: '网络日志异常流量分析', // 主标题 subtext: '', // 副标题 x: 'left' // x轴方向对齐方式 }, grid: { containLabel: true }, tooltip: { trigger: 'item', formatter: '{a} <br/>{b} : {d}%' }, // color: ['#1FC48D', '#F5A60A', '#6DC8EC', '#3F8FFF'], color: ['#1FC48D', 'red', '#6DC8EC', '#3F8FFF'], // backgroundColor: '#ffffff', legend: { orient: 'vertical', icon: 'circle', align: 'left', x: 'right', y: 'bottom', data: ['审计url异常', '正常网络日志', '流量日志异常', '威胁攻击日志'] }, series: [ { name: '网络日志状态', type: 'pie', radius: ['50%', '70%'], avoidLabelOverlap: false, center: ['40%', '50%'], itemStyle: { emphasis: { shadowBlur: 10, shadowOffsetX: 0, shadowColor: 'rgba(0, 0, 0, 0.5)' }, color: function (params) { // 自定义颜色 var colorList = ['#1FC48D', 'red', '#6DC8EC', '#3F8FFF'] return colorList[params.dataIndex] } }, data: this.opinionData2 } ] }) }, } } </script> 2.3 展示(可按自己需求更改前端样式)三、前后端数据交互实现3.1 创建数据库表结构:(根据你的业务需要创建)
表数据 3.2 后台代码的编写3.2.1 在bean包下创建QueryInfo类 该类实现得到前端请求的数据条数。相当于分页功能。 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包下创建Showdate类 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下创建Mapper 1.在Mapper中创建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下创建application.yml用于配置数据库和端口号 # 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下创建ShowdateDao 里面有两个接口,如果你需要操作数据库,就需要在ShowdateDao中编写接口方法; 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下创建ShowdateController 在ShowdateController中要注解使用空间 @Autowired ShowdateDao showdateDao;//你需要传给前端的数据库表 @Autowired FlowDao flowDao;//你的数据来源的效果数据库表 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; //前台刷新日志数据 @CrossOrigin @RequestMapping("/alldate")//前端请求通道 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()); } //校验 //封装校验后的流量日志 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; } //数据库数据来源的实现方法,就是改变数据库表Date1中得数据 @RequestMapping("/getupdata") public String updateDate(QueryInfo queryInfo){ String s = "流量日志异常"; String s1 ="审计url异常"; String s2 ="威胁攻击日志"; String s3 ="正常网络日志"; /*int count = getUserList(queryInfo); int count1 =getChickList(queryInfo); //四个方法需要你自己根据具体业务实现 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("异常类型:"+s); System.out.println("异常日志数量:"+count); String str = i >0?"success":"error"; return str; } } 3.2.6 修改前端接口 Js全部代码: <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: [ //清空前端测试数据 ] } }, mounted: function () { this.drawLine(); }, created() { this.getdateList(); //每次进入页面刷新数据库数据实现动态数据绑定 }, methods: { async drawLine () { // 调用post请求,获得后台数据库的数值 const { data: res } = await this.$http.get("alldate", { params: this.queryInfo }); if (res.flag != "success") { return this.$message.error("该数据获取失败!!!"); } console.log(res.flag) this.opinionData2 = res.opinionData2; // 将返回数据赋值 this.myChart = echarts.init(document.getElementById('myChart')) this.myChart.setOption({ title: { text: '网络日志异常流量分析', // 主标题 subtext: '', // 副标题 x: 'left' // x轴方向对齐方式 }, grid: { containLabel: true }, tooltip: { trigger: 'item', formatter: '{a} <br/>{b} : {d}%' }, // color: ['#1FC48D', '#F5A60A', '#6DC8EC', '#3F8FFF'], color: ['#1FC48D', 'red', '#6DC8EC', '#3F8FFF'], // backgroundColor: '#ffffff', legend: { orient: 'vertical', icon: 'circle', align: 'left', x: 'right', y: 'bottom', data: ['审计url异常', '正常网络日志', '流量日志异常', '威胁攻击日志'] }, series: [ { name: '网络日志状态', type: 'pie', radius: ['50%', '70%'], avoidLabelOverlap: false, center: ['40%', '50%'], itemStyle: { emphasis: { shadowBlur: 10, shadowOffsetX: 0, shadowColor: 'rgba(0, 0, 0, 0.5)' }, color: function (params) { // 自定义颜色 var colorList = ['#1FC48D', 'red', '#6DC8EC', '#3F8FFF'] return colorList[params.dataIndex] } }, data: this.opinionData2 } ] }) }, async getdateList() { // 调用post请求 const { data: res } = await this.$http.get("getupdata", { params: this.queryInfof }); if (res != "success") { return this.$message.error("该数据获取失败!!!"); } console.log(res) }, } } </script>
