spring boot 分层图解
安装idea
安装参考
idea插件使用一
idea插件使用二
项目热部署参考
配置阿里云镜像
<mirrors><mirror><id>nexus-aliyun</id><mirrorOf>central</mirrorOf><name>Nexus aliyun</name> <url>http://maven.aliyun.com/nexus/content/groups/public</url></mirror>
</mirrors>
项目启动
1) 安装node.js(请自行安装)
安装参考一
安装参考二
2)切换到项目根目录
3)在项目根目录执行:
npm install -g cnpm --registry=https://registry.npm.taobao.org
//切换模块下载镜像地址
4)项目根目录执行cnpm install,下载该项目依赖模块
提示如果安装“360安全卫士”或“电脑管家”,一定要关闭,不然报错
5)添加mark-down编辑依赖
cnpm install mavon-editor --save
6)用于解析md文档依赖
cnpm install markdown-it --save
cnpm install github-markdown-css
7)启动服务:项目根目录执行npm run dev,会自动打开前端首页(后端项目要提前部署好)
前端项目结构
build | 项目构建(webpack)相关代码 |
---|---|
config | 配置目录,包括端口号等。我们初学可以使用默认的:8089,当然线上为 |
node_modules | npm 加载的项目依赖模块 |
src | 要开发的目录,基本上要做的事情都在这个目录里。里面包含了几个目录及文件:assets: 放置一些图片,如logo等。components: 公共组件。 router:路由。 App.vue: 项目入口文件,我们也可以直接将组件写这里,而不使用 components 目录。 main.js: 项目的核心文件。 |
static | 静态资源目录,如图片、字体等。 |
index.html | 首页入口文件,可以添加一些 meta 信息 |
package.json | 项目配置文件 |
README.md | 项目的说明文档,markdown 格式 |
项目前端模块中引入了vuex,存放vuex的系列文件:
vuex需要遵守的规则:
1、应用层级的状态应该集中到单个 store 对象中。
2、提交 mutation 是更改状态的唯一方法,并且这个过程是同步的。
3、异步逻辑都应该封装到 action 里面。
1)首先 index.js 入口文件
2)store.js - 引入vuex,设置state状态数据,引入getter、mutation和action
3)state.js 相当于数据库
里面定义了数据结构,一些数据的初始状态
4)getters.js 顾名思义 取用,不做修改
5)mutation-types.js 存放Vuex常用的变量
引入mutation-types.js 操作里面定义的常用变量
6)action.js - 提交mutation以达到委婉地修改state状态,可异步操作
store.js文件
import VUE from 'vue'
import VUEX from 'vuex'VUE.use(VUEX)const state = {isPractice: false, //练习模式标志flag: false, //菜单栏左右滑动标志userInfo: null,menu: [// {// index: '1',// title: '考试管理',// icon: 'icon-kechengbiao',// content:[{item1:'考试查询',path:'selectExam'},{item2:'添加考试',path:'/addExam'}],// },// {// index: '2',// title: '题库管理',// icon: 'icon-tiku',// content:[{item2:'所有题库',path:'/selectAnswer'},{item3:'增加题库',path:'/addAnswer'},{path: '/addAnswerChildren'}],// },{index: '1',title: '成绩查询',icon: 'icon-performance',content:[{item1:'学生成绩查询',path:'/allStudentsGrade'},{path: '/grade'},{item2: '成绩分段查询',path: '/selectExamToPart'},{path: '/scorePart'},{item2: '成绩分科排序',path: '/selectExamToPart2'},{path: '/scorePart2'}],},{index: '2',title: '批改试卷',icon: 'el-icon-edit',content:[{item1:'未批改的应用题',path:'/studentApplication'},{item2: '已批改的应用题',path: '/studentApplication2'}],},{index: '3',title: '答疑解惑',icon: 'el-icon-chat-dot-round',content:[{item1:'发布问题',path:'/publishProblem'},{item2:'学生问题',path:'/solveProblem'}],},// {// index: '6',// title: '教师管理',// icon: 'icon-Userselect',// content:[{item1:'教师管理',path:'/teacherManage'},{item2: '添加教师',path: '/addTeacher'}],// },// {// index: '7',// title: '模块管理',// icon: 'icon-module4mokuai',// content:[{item1:'模块操作',path:'/module'}],// }],
}
const mutations = {practice(state,status) {state.isPractice = status},toggle(state) {state.flag = !state.flag},changeUserInfo(state,info) {state.userInfo = info}
}
const getters = {}
const actions = {getUserInfo(context,info) {context.commit('changeUserInfo',info)},getPractice(context,status) {context.commit('practice',status)}
}
export default new VUEX.Store({state,mutations,getters,actions,// store
})
更多用法
项目前端中index.html
项目中index.html和其他html差不多,但一般只定义一个空的根节点,在main.js里面定义的实例将挂载在根节点下,内容都通过vue组件来填充。
<!DOCTYPE html>
<html><head><meta charset="utf-8"><meta name="viewport" content="width=device-width,initial-scale=1.0"><title>锋芒频波测评系统</title><link rel="stylesheet" href="//at.alicdn.com/t/font_987928_pqv3jkd52jl.css"><link rel="icon" type="image/x-icon" href="../static/img/图标1.png"/></head><body><div id="app"></div><!-- built files will be auto injected --></body>
</html>
main.js里面定义的实例
new Vue({el: '#app',router,render: h => h(App),components: { App },template: '<App/>'
})
App.vue
一个vue页面通常由三部分组成:模板(template)、js(script)、样式(style)
- template
其中模板只能包含一个父节点,<router-view/>
为<router-view/> <router-view/>
的简写,是子路由视图,后面的路由页面都显示在此处。 - script
vue通常用es6来写,用export default导出,其下面可以包含数据data,生命周期(mounted等),方法(methods)等 - style
样式通过style标签<style></style>
包裹,默认是影响全局的,如需定义作用域只在该组件下起作用,需在标签上加scoped,<style scoped></style>
<template><div id="app"><router-view/></div>
</template><script>
export default {name: 'App'
}
</script><style>
ul {list-style: none;
}
a {text-decoration: none;
}
* {margin: 0;padding: 0;
}
#app {font-family: "Microsoft YaHei", "Helvetica", "Tahoma", "Geneva", "Arial", sans-serif;background-color: #eee;
}
</style>
main.js
main.js主要是引入vue框架,根组件及路由设置,并且定义vue实例。
// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'
import echarts from 'echarts'
import axios from 'axios'
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
import VueCookies from 'vue-cookies'
import mavonEditor from 'mavon-editor'
import 'mavon-editor/dist/css/index.css'Vue.use(ElementUI)
Vue.use(VueCookies)
Vue.use(mavonEditor)Vue.config.productionTip = false
Vue.prototype.bus = new Vue()
Vue.prototype.$echarts = echarts
Vue.prototype.$axios = axiosnew Vue({el: '#app',router,render: h => h(App),components: { App },template: '<App/>'
})
代码中的router相当于router:router,为ES6写法,在对象中,如果键值对一样的话,可以简写为一个;
components: { App }引入根组件App.vue,App即App:App;
template:'<App/>'
是简写形式,等价于 <App></App>
。
router
router下的index.js文件中的routes定义了路径为’/'的路由,该路由对应的页面是HelloWorld组件。
import Vue from 'vue'
import Router from 'vue-router'
Vue.use(Router)export default new Router({routes: [{path: '/',name: 'login', //登录界面component: () => import('@/components/common/login')},{path: '/changeUser',name: 'changeUser',component: () => import ('@/components/common/userManager')},{path: '/index', //教师主页component: () => import('@/components/admin/index'),children: [{path: '/', //首页默认路由component: () => import('@/components/common/hello')},{path:'/grade', //学生成绩component: () => import('@/components/charts/grade')},{path: '/selectExamToPart', //学生分数段component: () => import('@/components/teacher/selectExamToPart')},{path: '/selectExamToPart2', //学生分科成绩component: () => import('@/components/teacher/selectExamToPart2')},{path: '/scorePart',component: () => import('@/components/charts/scorePart')},{path: '/scorePart2', //单科成绩排序component: () => import('@/components/charts/scorePart2')},{path: '/searchStudentApplication', //单科成绩排序component: () => import('@/components/teacher/searchStudentApplication')},{path: '/allStudentsGrade', //所有学生成绩统计component: () => import('@/components/teacher/allStudentsGrade')},{path: '/examDescription', //考试管理功能描述component: () => import('@/components/teacher/examDescription')},{path: '/selectExam', //查询所有考试component: () => import('@/components/teacher/selectExam')},{path: '/addExam', //添加考试component: () => import('@/components/teacher/addExam')},{path: '/answerDescription', //题库管理功能介绍component: ()=> import('@/components/teacher/answerDescription')},{path: '/selectAnswer', //查询所有题库component: () => import('@/components/teacher/selectAnswer')},{path: '/addAnswer', //增加题库主界面component: () => import('@/components/teacher/addAnswer')},{path: '/addAnswerChildren', //点击试卷跳转到添加题库页面component: () => import('@/components/teacher/addAnswerChildren')},{path: '/studentManage', //学生管理界面component: () => import('@/components/teacher/studentManage')},{path: '/studentApplication', //展示要批改的应用题component: () => import('@/components/teacher/studentApplicationNoCorrect')},{path: '/studentApplication2', //展示批改过的应用题component: () => import('@/components/teacher/studentApplicationCorrect')},{path: '/solveProblem', //展示问题component: () => import('@/components/teacher/solveProblem')},{path: '/publishProblem', //展示问题component: () => import('@/components/teacher/publishProblem')},{path: '/addStudent', //添加学生component: () => import('@/components/teacher/addStudent')},{path: '/teacherManage',component: () => import('@/components/admin/tacherManage')},{path: '/addTeacher',component: () => import ('@/components/admin/addTeacher')},]},{path: '/student',component: () => import('@/components/student/index'),children: [{path:"/",component: ()=> import('@/components/student/myExam')},{path: '/manager', component: () => import('@/components/student/manager')},{path: '/update_stuinfo', component: () => import('@/components/student/update_stuinfo')},{path: '/examMsg', component: () => import('@/components/student/examMsg')},{path: '/message', component: () => import('@/components/student/message')},{path: '/studentScore', component: () => import("@/components/student/answerScore")},{path: '/scoreTable', component: () => import("@/components/student/scoreTable")}]},{path: '/answer',component: () => import('@/components/student/answer')},{path: '/registerstudent', component: () => import('@/components/student/registerstudent')},{path: '*',redirect: '/'}]
})
整个页面渲染过程
访问http://localhost:8088/显示的就是index.html页面,index.html原本只有一个根结点id=“app”。
main.js入口文件引入根组件App
前边我们已经提到,根组件App中,<router-view/>
是子路由视图,后面的路由页面都显示在此处,访问http://localhost:8088/,路由为‘/’,根据路由文件index.js,所以引入login组件。
login.vue

由于在config文件夹下index.js文件下创建"api",代替target里面的地址(后台请求),后面组件中我们掉接口时直接用api代替

引入JQuery依赖
cnpm install jquery --save
github-markdown-css样式文件-一般用作文章正文的样式美化
1.下载到项目中
cnpm i github-markdown-css
2.将样式放到模块化vue目录下,然后在 style中导入
<style scoped lang="less">
@import './github-markdown.css';
</style>
3.在vue脚手架中的 .postcssrc.js文件中加入 exclude: ‘github-markdown’ //css样式文件
module.exports = {// 配置要使用的 PostCSS 插件plugins: {// 配置使用 autoprefixer 插件// 作用:生成浏览器 CSS 样式规则前缀// VueCLI 内部已经配置了 autoprefixer 插件// 所以又配置了一次,所以产生冲突了// 'autoprefixer': { // autoprefixer 插件的配置// // 配置要兼容到的环境信息// browsers: ['Android >= 4.0', 'iOS >= 8']// },// 配置使用 postcss-pxtorem 插件// 作用:把 px 转为 rem'postcss-pxtorem': {rootValue ({ file }) {return file.indexOf('vant') !== -1 ? 37.5 : 75},// 配置要转换的 CSS 属性 // * 表示所有propList: ['*'],exclude: 'github-markdown' //css样式文件}}
4.在需要美化的正文部分加入github-markdown-css样式文件的 主样式类名
