文章目录
1、问题背景
问题如下:
- 现在我们有一个springboot的项目,启动后可以在localhost:8080访问网站并使用网站提供的服务。
- 我们想要打包为windows下的可执行文件exe,即 exe会自动打开一个窗口访问到该网站。
使用说明:
- 请先将项目打包为jar,并确保可以通过java -jar即可启动该web服务
- 使用前请先用java -jar xx.jar测试该项目可以成功访问,一切正常。
2、electron入门,使用electron打包静态页面或URL
什么是Electron?
- Electron是GitHub开发的一个开源框架。它通过使用Node.js和Chromium的渲染引擎完成跨平台的桌面GUI应用程序的开发。
Electron现已被多个开源Web应用程序用于前端与后端的开发,著名项目包括GitHub的Atom和微软的Visual Studio Code。 - Electron是大前端的重要组成部分。
如何安装Electron?

node -v
npm -v
npm config set ELECTRON_MIRROR http://npm.taobao.org/mirrors/electron/ #淘宝源
sudo npm install electron -g --allow-root -unsafe-perm=true # 全局安装
electron -v # 验证安装
使用electron-packager打包静态
安装electron-packager
一个用于打包electron应用的工具,只是打包成各个平台下可执行文件,并不是安装包
再全局安装 npm install electron-packager -g
打包静态:
参考资料:https://www.jianshu.com/p/a8a7820c8bfd
electron-packager . app --win --out presenterTool --arch=x64 --electron-version 1.0.0 --overwrite --ignore=node_modules
electron-packager . 可执行文件的文件名 --win --out 打包成的文件夹名 --arch=x64位还是32位 --electron-version版本号 --overwrite --ignore=node_modules(网上很多写法是--version 1.0.0 在高版本中的electron中,这个好像不行啦,必须要--electron-version这样写)
打包成功
会生成一个目录,然后打开这个目录,找到exe文件,打开即可。
打包成安装包:
https://www.cnblogs.com/kakayang/p/9559777.html
我们建立一个目录,放置三个文件
index.html
<!DOCTYPE html>
<html>
<head>
<!-- 此title会覆盖package.json中设置的name,作为应用顶部名称 -->
<title>my-app</title>
</head>
<body>
Hello World!
</body>
</html>
main.js
const app, BrowserWindow = require('electron')
let mainWindow
function createWindow ()
mainWindow = new BrowserWindow(
width: 1000,
height: 770,
webPreferences:
// nodeIntegration: true
)
mainWindow.loadFile('index.html')
// 改为使用loadURL加载微信网页版url地址
// mainWindow.loadURL('https://wx.qq.com/')
// mainWindow.loadURL('https://baidu.com/')
// mainWindow.loadURL('http://localhost:8080/')
mainWindow.on('closed', function ()
mainWindow = null
)
app.on('ready', createWindow)
package.json
"name": "my-app",
"version": "0.1.0",
"main": "main.js",
"scripts":
"start": "electron ."
,
"devDependencies":
"electron": "^5.0.6"
然后打开当前目录的终端使用如下命令:
electron-packager . app --win --out presenterTool --arch=x64 --electron-version 1.0.0 --overwrite --ignore=node_modules
就会生成一个可用的EXE文件
打包URL的方式是一样的,改一下main.js中的内容,使用加载URL方法即可
另外如果想不打包直接运行测试
可以在当前目录直接electron .
即可。
3、electron-builder下载出错
-
网络报错1
挂在了打包 electron-builder上面
如果本地没有安装electron-builder,npm run dist时先加载依赖https://registry.npmmirror.com/binary.html?path=electron/ npm config set ELECTRON_MIRROR=https://npm.taobao.org/mirrors/electron/ npm install electron-builder
-
网络报错2:
关于网络报错 https://segmentfault.com/a/1190000023314583 打包成安装包错误,下载不来winCodeSign https://github.com/trazyn/weweChat/issues/26 https://github.com/electron-userland/electron-builder/issues/3492 https://github.com/electron-userland/electron-builder/issues/5668 https://blog.csdn.net/qq_32682301/article/details/105234408 macOS: ~/Library/Caches/electron-builder Linux: ~/.cache/electron-builder windows: %LOCALAPPDATA%\\electron-builder\\cache @baochunliang C:\\Users\\Administrator\\AppData\\Local\\electron-builder\\cache 路径下要先建winCodeSign,在把下载的winCodeSign-1.9.0整个文件夹放进去,nsis与nsis-resources同样操作就可以打包成功。

缺少jquery
jquery判断是否加载成功 https://www.html.cn/qa/jquery/15411.html https://github.com/electron/electron/issues/28511
4、使用electron打包springboot

参考以下大佬的文章

首先是下载官方的electron-quick-start项目
https://github.com/electron/electron-quick-start

然后替换preload.js,修改main.js
preload.js
const contextBridge = require('electron') const spawn, exec = require('child_process') const path = require('path') contextBridge.exposeInMainWorld('myAPI', startServerForSpawn: () => let path1 = path.join(__dirname, 'app/ruoyi-admin.jar'); const ls = spawn('java', ['-jar', path1]); ls.stdout.on('data', (data) => if(data.toString().indexOf("Started RuoYiApplication") !== -1) window.location.href="http://localhost:80"; ); ls.stderr.on('data', (data) => console.error(`stderr: $data`); alert("启动服务异常"); ); ls.on('close', (code) => console.log(`child process exited with code $code`); ); , startServerForbat: () => const bat = spawn(path.join(__dirname, 'my.bat')); bat.stdout.on('data', (data) => console.log(data.toString()); if(data.toString().indexOf("Started RuoYiApplication") !== -1) window.location.href="http://localhost:80"; ); bat.stderr.on('data', (data) => console.error(data.toString()); ); bat.on('exit', (code) => console.log(`Child exited with code $code`); ); )
main.js
// Modules to control application life and create native browser window const app, BrowserWindow = require('electron') const path = require('path') function createWindow () // Create the browser window. const mainWindow = new BrowserWindow( width: 800, height: 600, webPreferences: nodeIntegration:true, contextIsolation:true, preload: path.join(__dirname, 'preload.js') ) // and load the index.html of the app. mainWindow.loadFile('index.html') // Open the DevTools. // mainWindow.webContents.openDevTools() // This method will be called when Electron has finished // initialization and is ready to create browser windows. // Some APIs can only be used after this event occurs. app.whenReady().then(() => createWindow() app.on('activate', function () // On macOS it's common to re-create a window in the app when the // dock icon is clicked and there are no other windows open. if (BrowserWindow.getAllWindows().length === 0) createWindow() ) ) // Quit when all windows are closed, except on macOS. There, it's common // for applications and their menu bar to stay active until the user quits // explicitly with Cmd + Q. app.on('window-all-closed', function () if (process.platform !== 'darwin') app.quit() ) // In this file you can include the rest of your app's specific main process // code. You can also put them in separate files and require them here.

替换package.json

新建两个html
index.html<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <meta http-equiv="Content-Security-Policy" content=""> <title>index</title> </head> <body> <!-- We are using Node.js <span id="node-version"></span>, Chromium <span id="chrome-version"></span>, and Electron <span id="electron-version"></span>. <p id="p1"></p> <p id="p2"></p> <script> document.getElementById("p1").innerHTML = "Hello world!"; document.getElementById("p2").innerHTML = 10+20; </script> <script src="./static/js/jquery.min.js"> </script> <script> $(document).ready(function() alert('dom加载完成'); ); </script> --> <script src="./static/js/jquery.min.js"> </script> <script> $(document).ready(function() $.ajax( timeout: 200, type: 'GET', url: 'http://localhost:8080', data: , success: function(obj) window.location.href = "http://localhost:8080" , error: function(obj) window.location.href = "loading.html"; ) ) </script> </body> </html>
loading.html
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <!-- https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP --> <!-- <meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self'"> --> <title>loading</title> </head> <body> <h1>Loading</h1> <div>正在启动,请等待!</div> <script> window.myAPI.startServerForbat(); console.log("-----------hello-------------") </script> </body> </html>

新建app和jre文件夹,新建bat脚本
my.bat脚本:cd ./jre/bin java -jar ../../app/admin.jar
app文件夹中放置打包好的jar文件
jre文件夹中放置可以运行的jre环境 -
最后使用以下命令打包:
npm run dist
