开始
本篇开始搭建管理后台的前端项目，其实纯讲前端好像没啥营养，刚好本项目是采用旧项目改造的基础框架搭建的，就讲讲改造过程中，遇到难点，以及如何处理！主要是笔者工作期间的产物，在给后端项目做前后端技术分离时，将bootstrap+jquery+adminLTE改造成vue项目。
当前项目：
https://github.com/liaz-repo/liaz-admin-web.git
先附上app成品的gitee地址（漫画/轻小说app）：
https://gitee.com/liaz-app/liaz-android/releases/download/1.0.0/app-arm64-v8a-release.apk
先说一句，这后台样式可能会有大部分人熟悉，像是某某音、某某聊、某某界的运营后台；如果有幸认识它的话，贵公司有机会能尝试笔者这旧改方案哦！（改造项目已上线运行）
难点
1.jquery与vue兼容
2.adminLTE菜单加载
3.第三方插件库兼容
4.批量代码搬迁
改造过程中，第三方库的兼容问题是最大，困扰了笔者好几天，最后还好能解决。

到这一步，vue项目已经创建好，开始旧改的艰难旅程。。。
npm安装
经过一段时间摸索，原先旧项目中有部分库在npm中可安装使用，便直接安装，但需指定版本。（因选择eslint标准配置，存在版本不兼容报错，需强制执行–force）
npm install [email protected] --force
npm install [email protected] --force
npm install [email protected] --force
npm install [email protected] --force
npm install [email protected] --force
npm install [email protected] --force
npm install [email protected] --force
npm install [email protected] --force
npm install axios --force
顺带改一下package.json执行命令
"scripts": {
"dev": "vue-cli-service serve --mode development",
"build": "vue-cli-service build --mode production",
"lint": "vue-cli-service lint"
},
jquery和adminLTE整合
在main.js导入关键依赖
import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
import 'jquery'
import 'jquery.md5'
import 'bootstrap/dist/css/bootstrap.min.css'
import 'bootstrap/dist/js/bootstrap.min'
import 'font-awesome/css/font-awesome.min.css'
import 'ionicons/css/ionicons.min.css'
import 'admin-lte/dist/css/AdminLTE.min.css'
import 'admin-lte/dist/css/skins/skin-red-light.min.css'
import 'admin-lte/dist/js/app.min'
createApp(App).use(store).use(router).mount('#app')
public/index.html添加adminLTE的样式class：hold-transition skin-blue sidebar-mini
<!DOCTYPE html>
<html lang="">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width,initial-scale=1.0">
<link rel="icon" href="<%= BASE_URL %>favicon.ico">

</head>
<body class="hold-transition skin-blue sidebar-mini">
<noscript>
<strong>We're sorry but <%= htmlWebpackPlugin.options.title %> doesn't work properly without JavaScript enabled. Please enable it to continue.</strong>
</noscript>
<div id="app"></div>
<!-- built files will be auto injected -->
</body>
</html>
难点一：jquery与vue兼容
第一个难点来了，vue识别不出jquery，在执行npm run dev后页面报错
index.js:235 Uncaught ReferenceError: jQuery is not defined
at eval (index.js:235:4)
at ./node_modules/jquery.md5/index.js (chunk-vendors.js:202:1)
at __webpack_require__ (app.js:313:32)
at fn (app.js:564:21)
at eval (main.js:8:68)
at ./src/main.js (app.js:74:1)
at __webpack_require__ (app.js:313:32)
at app.js:1488:109
at __webpack_require__.O (app.js:355:23)
at app.js:1489:53
需修改eslint的配置
.eslintrc.js
添加jquery:true
module.exports = {
root: true,
env: {
node: true,
jquery: true
},
extends: [
'plugin:vue/vue3-essential',
'@vue/standard'
],
parserOptions: {
parser: '@babel/eslint-parser'
},
rules: {
'no-console': process.env.NODE_ENV === 'production' ? 'warn' : 'off',
'no-debugger': process.env.NODE_ENV === 'production' ? 'warn' : 'off'
}
}
vue.config.js
添加webpack插件，指定全局jquery变量
const { defineConfig } = require('@vue/cli-service')
var webpack = require('webpack')
module.exports = defineConfig({
transpileDependencies: true,
chainWebpack: config => {
config
.plugin('html')
.tap(args => {
args[0].title = '管理后台'
return args
})
},
configureWebpack: {
plugins: [
new webpack.ProvidePlugin({
$: 'jquery',
jQuery: 'jquery',
'windows.jQuery': 'jquery',
Popper: ['popper.js', 'default']
}),
],
},
devServer: {
headers: {
'Access-Control-Allow-Origin': '*',
},
proxy: {
'/': {
ws: false,
target: process.env.VUE_APP_API_BASE_URL,
changeOrigin: true,
pathRewrite: {
'^/': ''
}
}
},
},
})
到此，jquery与vue的兼容问题解决。
难点二：adminLTE加载菜单
adminLTE是个模版框架，并没有提供兼容vue写法，只能自己想办法处理。
笔者想到利用vue的component标签，通过切换组件名称，实现页面切换，因此需要将所有的vue页面预先加载到vue中。
<component :is="componentName"></component>
components.js
export default {
install: function (Vue) {
const files = require.context('@/views', true, /\.vue$/);
let components = {};
files.keys().forEach(key => {
components[key.replace(/(\.\/|\.vue)/g, '')] = files(key).default;
});
Object.keys(components).forEach(item => {
if (components[item].name) {
Vue.component(components[item].name, components[item]);
}
});
},
}
在main.js导入
import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
import 'jquery'
import 'jquery.md5'
import 'bootstrap/dist/css/bootstrap.min.css'
import 'bootstrap/dist/js/bootstrap.min'
import 'font-awesome/css/font-awesome.min.css'
import 'ionicons/css/ionicons.min.css'
import 'admin-lte/dist/css/AdminLTE.min.css'
import 'admin-lte/dist/css/skins/skin-red-light.min.css'
import 'admin-lte/dist/js/app.min'
import components from '@/utils/components'
createApp(App).use(store).use(router).use(components).mount('#app')
也同时将adminLTE提供的模版页面（node_modules/admin-lte/index.html），拆解成三部分
footer
<template>
<footer class="main-footer">
<div class="pull-right hidden-xs">
<b>Version</b> 2.0.0
</div>
<strong>Copyright © 2024 <a href="">LIAZ</a>.</strong> All rights

</template>

}
</script>

<script>
import store from '@/store';
export default {
name: 'HeaderView',
data() {
return {

lastTime: ""
};
},
created() {
this.name = store.getters.name;
this.avatar = store.getters.avatar;
this.lastTime = store.getters.lastTime;
},
methods: {
logout() {
store.dispatch('logout');
}
}
}
</script>
<style scoped></style>
maintainer
这部分是重点，将菜单加载改成使用component标签切换，点击菜单时修改局部变量componentName，实现vue组件切换。
<template>

难点三：第三方库改造
旧项目中使用的第三方插件库，大部分都因年代久远，失去维护；在baidu与google上都找不到相同的源代码，巨头疼。
尝试以下几个方案：
一、npm安装接近版本或类似的库，因旧代码报错，无法兼容（失败）
二、直接复制源代码过来，在main.js导入，代码无法加载，都报undefined（失败）
最后经过好几天摸索，发现以下两种方式可解决。
1.插件库改造
对插件库代码进行改造，套上nodejs的加载结构，导入便可自动执行，主要都是jquery的插件库。
(function (factory) {
var define;
if (typeof define === 'function' && define.amd) {
define(['jquery'], factory);
} else if (typeof exports === 'object') {
factory(require('jquery'));
} else {
factory(jQuery);
}
}(function ($, obj = undefined) {
// 此次放原先插件库的代码
...
}));
在main.js导入
import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
import 'jquery'
import 'jquery.md5'
import 'bootstrap/dist/css/bootstrap.min.css'
import 'bootstrap/dist/js/bootstrap.min'
import 'font-awesome/css/font-awesome.min.css'
import 'ionicons/css/ionicons.min.css'
import 'admin-lte/dist/css/AdminLTE.min.css'
import 'admin-lte/dist/css/skins/skin-red-light.min.css'
import 'admin-lte/dist/js/app.min'
import '@/assets/plugins/bootstrap-table/css/bootstrap-table.css'
import '@/assets/plugins/bootstrap-table/js/bootstrap-table'
import '@/assets/plugins/bootstrap-table/js/locale/bootstrap-table-zh-CN'

import '@/assets/plugins/bootstrap-treeview/js/bootstrap-treeview.min'
import components from '@/utils/components'
createApp(App).use(store).use(router).use(components).mount('#app')
.eslintrc.js
还需关闭eslint一些校验，旧代码不规范，直接启动不了，害
module.exports = {
root: true,
env: {
node: true,
jquery: true
},
extends: [
'plugin:vue/vue3-essential',
'eslint:recommended'

难点三：登录后的样式污染
目前就这个问题，笔者这三脚猫的前端技术，实在无法攻克；只能通过一种取巧的办法，先跳转到个空白页面，再判断是否链接跳转来源方式，从而重定向回首页。
views/login/index.vue
登录函数代码
export default {
name: "LoginView",
created() {
this.init();
this.bubble();
},
methods: {
bubble() {
var $ul = $('<ul id="bubble-wrapper"/>');
for (var i = 0; i < 10; i++) {
$ul.append($('<li/>'));
}
$("body").append($ul);
},
init() {
this.$nextTick(function () {
let $this = this;
$("#loginBtn").click(function () {
$this.login();
});
});
},
login() {
let username = $("#username").val();
let password = $("#password").val();
if (username.trim() == '') {
$(".loginTips").html("账号不能为空！");
return;
} else if (password.trim() == '') {
$(".loginTips").html("密码不能为空！");
return;
}
login({
'username': username,
'password': $.md5(password),
}).then(res => {
if (res.code == global.HTTP_STATUS.OK) {
console.log("login success.");
this.storeAccessToken(res.data.accessToken);
this.getSysConfs();
} else {
$(".loginTips").html(res.message).css("padding", "3px 5px");
}
});
},
storeAccessToken(accessToken) {
setStore({
name: "access_token",
content: accessToken,
type: "session"
});
},
getSysConfs() {
store.dispatch('getSysConfs').then(res => {
console.log(res);
this.updateUser();
});
},
updateUser() {
store.dispatch('getUser').then(res => {
console.log(res);
window.location.href = '#/blank';
});
},
},
};
BlankView.vue
<template>
<div></div>
</template>
<script>
import router from '@/router';
export default {
name: 'BlankView',
created() {
//处理css样式污染问题
if (window.performance.navigation.type == window.performance.navigation.TYPE_RELOAD) {
router.push('/home');
} else {
router.go(0);
}
}
}
</script>
<style scoped></style>
难点四：代码迁移
以下附上JAVA批量处理脚本，将原项目中的所有页面批量转化为vue页面。
import java.io.*;
public class VueScriptTest {
public static void main(String[] args) {
String sourcePath = "/html";
String targetPath = "/views";
File sourceDirectory = new File(sourcePath);
File targetDirectory = new File(targetPath);
if (!targetDirectory.exists()) {
boolean isMkdir = targetDirectory.mkdirs();
}
processFiles(sourceDirectory, targetDirectory);
}
private static void processFiles(File sourceDirectory, File targetDirectory) {
File[] files = sourceDirectory.listFiles();
if (files != null) {
for (File file : files) {
if (file.isDirectory()) {
File newTargetDirectory = new File(targetDirectory, file.getName());
boolean isMkdir = newTargetDirectory.mkdirs();
processFiles(file, newTargetDirectory);
} else if (file.getName().endsWith(".html")) {
try {
String newFileNameBase = toCamelCase(file.getName().replace(".html", "")).trim();
String componentName = upperFirst(newFileNameBase) + "View";
BufferedReader reader = new BufferedReader(new FileReader(file));
StringBuilder content = new StringBuilder();
StringBuilder styleContent = new StringBuilder();
StringBuilder scriptContent = new StringBuilder();
boolean inStyleTag = false;
boolean inScriptTag = false;
String line;
while ((line = reader.readLine()) != null) {
if (isNonEmptyNonCommentLine(line)) {
if (line.trim().startsWith("<style>")) {
inStyleTag = true;
line = line.replace("<style>", "<style scoped>");
}
if (line.trim().startsWith("<script>")) {
inScriptTag = true;
}
if (inStyleTag) {
styleContent.append(line).append("\n");
} else if (inScriptTag) {
if (line.trim().startsWith("<script>")) {
scriptContent.append(line).append("\n");
scriptContent.append("export default {\n" + " name: \"").append(componentName).append("\",\n").append(" setup() {},\n").append(" created() {\n").append(" this.$nextTick(function () {\n").append(" this.initData();\n").append(" });\n").append(" },\n").append(" methods: {\n").append(" initData() {\n");
} else {
if (line.contains(".bootstrapTable") && line.contains("destroy")) {
scriptContent.append(line).append("\n");
scriptContent.append("// 清空分页组件的容器\n");
scriptContent.append("$('.fixed-table-pagination').empty();\n");
} else {
if (line.trim().contains("</script>")) {
scriptContent.append(" }\n" + " }\n" + "};\n");
}
scriptContent.append(line).append("\n");
}
}
} else {
// 添加import语句
if (line.contains("<script src=\"/static/js/admin/style.js\"></script>")) {
// 在scriptContent中找到<script>的位置，下一行插入import语句
int scriptIndex = scriptContent.indexOf("<script>");
if (scriptIndex != -1) {
scriptContent.insert(scriptIndex + "<script>".length(), "\nimport '@/utils/style.js';");
}
} else {
content.append(line).append("\n");
}
}
} else {
content.append(line).append("\n");
}
if (inStyleTag && line.trim().endsWith("</style>")) {
inStyleTag = false;
}
if (inScriptTag && line.trim().endsWith("</script>")) {
inScriptTag = false;
}
}
reader.close();
content.insert(0, "<template>\n");
content.append("</template>\n");
content = new StringBuilder(content.toString().replace("type=\"date\"", ""));
// 添加import语句
if (scriptContent.toString().contains("TableHelper")) {
// 在scriptContent中找到<script>的位置，下一行插入import语句
int scriptIndex = scriptContent.indexOf("<script>");
if (scriptIndex != -1) {
scriptContent.insert(scriptIndex + "<script>".length(), "\nimport TableHelper from '@/utils/bootstrap-table-helper';");
}
}
content.append(scriptContent).append("\n");
content.append(styleContent);
String newFileName = upperFirst(newFileNameBase) + "View.vue";
File newFile = new File(targetDirectory, newFileName);
FileWriter writer = new FileWriter(newFile);
writer.write(content.toString());
writer.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
}
private static boolean isNonEmptyNonCommentLine(String line) {
return !line.trim().isEmpty() && !line.trim().startsWith("<!--");
}
private static String toCamelCase(String fileName) {
StringBuilder result = new StringBuilder();
boolean nextUpperCase = false;
for (char c : fileName.toCharArray()) {
if (c == '-' || c == '_') {
nextUpperCase = true;
} else {
if (nextUpperCase) {
result.append(Character.toUpperCase(c));
nextUpperCase = false;
} else {
result.append(Character.toLowerCase(c));
}
}
}
return result.toString();
}
private static String upperFirst(String name) {
char[] ch = name.toCharArray();
ch[0] -= 32;
return new String(ch);
}
}
总结
整个项目改造真的细节很多，写可能很大部分没写全，文章前面已经放上git地址，大伙可下载代码，自行参透。
