README
Apache-2.0

一、项目描述

  • 前端用的是vue + DataV + echarts进行的开发。
  • 后端服务的架构为spring boot + xxl-jod定时任务处理来搭建整个服务,数据库用的是mysql。
  • 整合了四个类型的数据大屏,重新构建了主页,可以通过主页来选择不同类型的数据大屏进行查看。
  • 项目需要全屏展示(按 F11)。
  • 项目部分区域使用了全局注册方式,增加了打包体积,在实际运用中请使用按需引入
  • 项目环境:vue-cli-3.0、webpack-4.0、npm-6.13、node-v12.16、java-1.8。
  • 在本项目上做进一步的改造需要具备一些vue的基础,比如组件,路由,基本语法等。
  • 演示地址:http://www.pwriter.top:8082/ 未启动后端项目。

三、使用说明

  1. 如何启动前端项目

    • 需要提前安装好nodejsnpm,下载项目后在项目主目录下运行npm/cnpm install拉取依赖包,然后使用 vue-cli 或者直接使用命令npm run serve,就可以启动项目,启动项目后需要手动全屏(按 F11)。
  2. 如何启动后端项目

    • 后端项目使用了xxl-job做一个定时任务处理,当然,你也可以使用spring boot内置的定时处理,如**@Scheduled**注解,需要更改big-screen后端的xxl-job服务地址在下图的配置文件中做修改 xxl-job服务地址配置
    • 项目中集成了xxl-job的源码,先启动xxl-job-admin,注意需要本地maven install xxl-job-core,在启动后端服务,xxl-job的详细说明,请访问作者的官方文档
  3. 如何动态渲染图表

    • components/echart下的文件,比如drawPie()是渲染函数,echartData是需要动态渲染的数据,当外界通过props传入新数据,我们可以使用watch()方法去监听,一但数据变化就调用this.drawPie()并触发内部的.setOption函数,重新渲染一次图表。
//这里是子组件内部

props: ["listData"],
watch: {
  listData(newValue) {
     this.echartData= newValue;
     this.drawPie();
   },
  },
methods: {
  drawPie() {
  	.....
  	'渲染节点名称'.setOption(option);
  }
 }
  1. 跨域配置
    • 一般我们后端和前端的服务器地址是不一样的,在前端调用后端接口的时候会存在跨域的问题,项目中的跨域配置在 store/vue-store.js 中,配置项做了详细说明,如果需更多配置项,请查阅vue官网信息-路由
export default new Vuex.Store({
	state: {},
	mutations: {},
	actions: {},
	modules: {},
	dev: {
		// Paths
		assetsSubDirectory: 'static',
		assetsPublicPath: '/',
		// 后端请求地址代理,配置后testIp再之后的页面调用时就直接指代 http://127.0.0.1:8085
		proxyTable: {
			'/api': {
				target: 'http://127.0.0.1:8085',
				changeOrigin: true,
				pathRewrite: {
					'^/api': ''
				}
			}
		},
		// Various Dev Server settings
		host: 'localhost', // can be overwritten by process.env.HOST
		port: 8085, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined
		autoOpenBrowser: false,
		errorOverlay: true,
		notifyOnErrors: true,
		poll: false, // https://webpack.js.org/configuration/dev-server/#devserver-watchoptions-
		devtool: 'cheap-module-eval-source-map',
	}

})
  1. 前端接口配置
  • 为了方便管理调用的接口,抽取了一个配置类,如下图 接口配置文件
let resquest = "/api";

对应vue-store.js文件中的proxyTable配置中的/api,会映射对应的后端接口路径 跨域配置

  • 目前只在epidemic-screen.vue中与后端对接了一个接口,后续可以根据自己的需求扩展。
methods: {
			cancelLoading() {
				setTimeout(() => {
					this.loading = false;
				}, 2000);
			},

			// 调用接口获取数据
			fetchList() {
				getListAPI().then(res => {
					if(res != undefined)
					{
						if( res.data.code == '200' ){
							this.nowTime = res.data.data;
							console.log(res.data);
						}else{
							clearInterval(this.timer);
						}
					}else{
						alert(res);
						clearInterval(this.timer);
					}
				});
				// this.timer = setInterval(this.fetchList, 10000);
			}
		}
  1. 如何更换边框
    • 边框是使用了 DataV 自带的组件,如:
<dv-border-box-1></dv-border-box-1>
<dv-border-box-2></dv-border-box-2>
...

只需要去 views 目录下去寻找对应的位置去查找并替换就可以,具体的种类请去 DavaV 官网查看

  1. 如何更换图表
    • 直接进入 components/echart 下的文件修改成你要的 echarts 模样,可以去echarts 官方社区里面查看案例。
