1.使用vue-cli创建前端项目
运用vue-cli工具可以很轻松地构建前端项目,当然,使用webstorm来构建会更加简洁(如图)。本文推荐使用webstorm,因为在后续开发中,ide会使我们的开发更加简洁。部分配置如图:
2.navbar编写
作为一个webapp,navbar作为应用的导航栏是必不可少的。在本项目中,笔者引入了bootstrap对navbar进行了轻松地构建。在vue中我们需要在components文件夹中将我们的组件加进去,对于本工程来说,navbar是我们要加入的第一个组件,他独立于router之外,一直固定在网页上方。
2.1 首先,我们使用npm来安装vue,vue-cli,bootstrap
1

|
npm install vue npm install -g vue-cli npm install --save bootstrap jquery popper.js |
2.2 接下来我们在components目录下new一个vue组件,并且在main.js中引入bootstrap依赖:
1
2
|
import 'bootstrap/dist/css/bootstrap.min.css' import 'bootstrap/dist/js/bootstrap.min' |
2.3 下面就可以开始写代码了,由于本文只关注table相关的功能,所以导航栏中除了script意外的元素都已经disable,代码如下:

<template> <nav class = "navbar navbar-expand-lg navbar-dark bg-dark" > <span class = "navbar-brand mb-0 h1" >vue-springboot</span> <button class = "navbar-toggler" type= "button" data-toggle= "collapse" data-target= "#navbarnav" aria-controls= "navbarnav" aria-expanded= "false" aria-label= "toggle navigation" > <span class = "navbar-toggler-icon" ></span> </button> <div class = "collapse navbar-collapse" id= "navbarnav" > <ul class = "navbar-nav" > <li class = "nav-item" > <router-link class = "nav-link" to= "/home" >home</router-link> </li> <li class = "nav-item active" > <router-link to= "/" class = "nav-link" >script</router-link> </li> <li class = "nav-item" > <router-link to= "/history" class = "nav-link" >history</router-link> </li> </ul> </div> </nav> </template> <script> export default { name: "mynavbar" } </script> <style scoped> </style> |
2.3 在app.vue中引入mynavbar
3.script table编写
作为自动化工具,必不可少的一部分就是引入script,我们希望用户能够自由地使用h5界面进行script的编写,因此在这里使用了vue的数据双向绑定进行table crud。
3.1 新建一个vue组件scripttable,代码如下:

<template> <div class = "container-fluid" id= "scripttable" > <h3>my script</h3> <form style= "margin-top: 1rem" > <input type= "file" @change = "getfile($event)" class = "" multiple/> <input type= "button" value= "upload" @click = "submit($event)" class = "btn btn-dark" > </form> <table class = "table table-hover text-center table-bordered" style= "word-break: break-all; word-wrap: break-word;margin-top: 1rem;" > <thead> <th>#</th> <th>platform</th> <th>action</th> <th>path</th> <th>value</th> <th>wait</th> <th>screenshot</th> <th>change</th> </thead> <tbody> <tr v-cloak v- for = "(item, index) in steps" > <th>{{index+ 1 }}</th> <td>{{item.platform}}</td> <td>{{item.action}}</td> <td>{{item.path}}</td> <td>{{item.value}}</td> <td>{{item.wait}}</td> <td>{{item.screenshot}}</td> <td><a href= "#" v-on:click= "edit(item)" >edit</a> | <a href= "#" v-on:click= 'aaa(index)' >delete</a> </td> </tr> <tr> <th></th> <td><select class = "form-control" v-model= "stepstemp.platform" > <option>web</option> <option>android</option> </select></td> <td><select class = "form-control" v-model= "stepstemp.action" > <option>click</option> <option>get</option> <option>input</option> <option>swipe</option> </select></td> <td><input class = "form-control" v-model= "stepstemp.path" placeholder= "enter the xpath" ></td> <td><input class = "form-control" v-model= "stepstemp.value" placeholder= "enter the input value" ></td> <td><input class = "form-control" v-model= "stepstemp.wait" placeholder= "waiting seconds" ></td> <td><select class = "form-control" v-model= "stepstemp.screenshot" > <option>yes</option> <option>no</option> </select></td> <td> <button class = "btn btn-sm btn-dark" v-on:click= 'save' v- if = "isnotedit" >save</button> <button class = "btn btn-sm btn-primary" v-on:click= 'saveedit' v- else >saveedit</button> </td> </tr> </tbody> </table> <hr/> </div> </template> <script> import vue from 'vue' import axios from 'axios' export default { name: "scripttable" , data() { return ({ steps: [], stepstemp: { platform: '' , action: '' , path: '' , value: '' , wait: '' , screenshot: '' }, isnotedit: true }); }, methods: { save: function () { this .steps.push( this .stepstemp); this .stepstemp = { platform: '' , action: '' , path: '' , value: '' , wait: '' , screenshot: '' }; }, aaa: function (index) { this .steps.splice(index, 1 ) }, edit: function (item) { this .isnotedit = false ; this .stepstemp = item; }, saveedit: function () { this .isnotedit = true ; this .stepstemp = { platform: '' , action: '' , path: '' , value: '' , wait: '' , screenshot: '' }; } } } </script> <style scoped> </style> |
3.3 运行dev,打开localhost:8080
npm run dev
前端页面效果如下:
至此,本文相关的纯前端部分完成地差不多了,加上mock的数据后,我们可以开始进行后端的开发了。
4.使用spring initializr创建后端项目
为了更轻松地构建工程,构建restful api以及更轻松地配置请求处理,笔者选择了spring boot作为后端框架。
4.1 首先我们使用idea集成的spring initializr来构建项目,部分配置如图:
4.2 接下来在pom.xml中引入poi依赖,点击import change。如下所示:
1
2
3
4
5
|
<dependency> <groupid>org.apache.poi</groupid> <artifactid>poi-ooxml</artifactid> <version> 4.0 . 0 </version> </dependency> |
4.3 接下来我们在application.properties中配置server.port=8088,与前端项目分开
5.pojo类step的编写
下面是对pojo类的编写,本文所需的pojo只有step一种,与前端的table相对应,代码如下:
1
2
3
4
5
6
7
8
9
10
|
import lombok.data; @data public class step { private string platform; private string action; private string path; private string value; private int wait; private string screenshot; } |
6.uploadcontroller的编写
接下来是对前端post请求的handler(controller)进行编写,我们将上传这个post请求与"/uploadfile"相对应,注意加入@crossorigin注解实现跨域,代码如下:

7.loadservice的编写
下面该编写service来读取请求中传送的文件了,简单地来说只有一个步骤,将excel中的script转换为pojo的链表并在controller中作为responsebody返回.
7.1 首先创建service接口,代码如下:

package com.daniel.vuespringbootuploadbe; import org.springframework.stereotype.service; import java.io.file; import java.util.list; @service public interface loadservice { list<step> casttostep(file file); } |

8.搭建简单的restful api
文章临近尾声,现在前后端的独立代码基本开发完毕,是时候搭建restful了,本文中的api非常简单,就是对上传做出响应,并将返回的json写入界面上的table中,完成script导入,npm安装axios后,在scripttable组件中加入如下代码:

getfile: function (event) { this .file = event.target.files[ 0 ]; console.log( this .file); }, submit: function (event) { event.preventdefault(); let formdata = new formdata(); formdata.append( "file" , this .file); axios.post( 'http://localhost:8088/upload' , formdata) .then(function (response) { for (let i = 0 ; i < response.data.length; i++) { var tempdata = { platform: response.data[i].platform, action: response.data[i].action, path: response.data[i].path, value: response.data[i].value, wait: response.data[i].wait, screenshot: response.data[i].screenshot }; this .steps.push(tempdata); } }.bind( this )) . catch (function (error) { alert( "fail" ); console.log(error); }); } |
9.运行服务,编写script并上传
接下来我们创建一个excel,按如图格式编写简单script,运行前后端服务,实现上传:
运行后,excel文件会上传到后端工程的static的temp目录中
总结
