前言

本项目为简易的全栈项目,其中前端项目使用到了vue3、ts、Element Plus、axios等技术栈;后端项目使用到了springboot、jdbc、mysql、maven等技术


一、前端项目

1、使用vue脚手架创建项目

1.1检查vue版本

输入命令vue -V(V要大写),版本需要在4.5.1之后

1.2 使用vue脚手架创建项目

1、使用命令vue create vue3-element-demo 创建Vue项目。
2、通过上下键选择,选择 Manually select features,按回车,手动进行配置。

3、通过上下键选择,通过空格键选中(使用Babel,TypeScript,Router、Vuex、CSS Pre-processors、Linter / Formatter),按回车

4、选择vue3按回车

5、是否使用 Class 风格装饰器,此处输入【y】,然后回车确认;

6、Babel 和 TS 是否一起使用,用于现代模式、自动检测的 polyfills 和转译 JSX,此处输入【y】,然后回车确认;

7、是否使用history路由模式,此处输入【n】,即使用默认的 hash 模式,然后回车确认;

8、选择 CSS 预处理器,按上下方向键来选择,笔者习惯了 Less,然后回车确认;

9、选择第一个ESLint with error prevention only(仅具有错误预防功能的ESLint)


10、Babel、ESLint 等插件的配置是单独的文件进行配置,还是都在 package.json 文件里面?此处输选择 package.json 咯,并不想太多零散的配置文件,然后回车确认;

11、是否保存当前创建 Vue3 项目的特性配置,下次再创建 Vue 项目的时候,可以选择该特性,然后回车确认即可创建完成。这个可以不用保存,输入【n】,然后回车确认;
12、项目创建中;

项目创建成功:


运行项目

2、删除项目多余文件,修改配置项目

2.1、删除以下文件

2.1、在views下创建index文件

<template><div>我的首页</div></template><script lang="ts">export default {name: 'Index'}</script><style scoped></style>

2.2、修改router/index.ts路由文件:


编译时会有报错:
vue eslint报错:Component name “index“ should always be multi-word.eslintvue/multi-word-component-names

原因:除了根组件(App.vue)外,自定义组件名称应该由多单词组成,防止和html标签冲突。
解决方法,关闭eslint校验,重新编译就正常了
lintOnSave: false

2.3、修改App.vue文件:

<template><div id="app"><router-view/></div></template><style lang="less">html,body,#app {width: 100%;height: 100%;}</style>

运行效果:

2.4、初始化页面样式以及清除浮动

新建css/resset.css文件,并在index.html文件中引入,初始化样式

/** * Eric Meyer's Reset CSS v2.0 (http://meyerweb.com/eric/tools/css/reset/) * http://cssreset.com */html, body, div, span, applet, object, iframe, h1, h2, h3, h4, h5, h6, p, blockquote, pre, a, abbr, acronym, address, big, cite, code, del, dfn, em, img, ins, kbd, q, s, samp, small, strike, strong, sub, sup, tt, var, b, u, i, center, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, table, caption, tbody, tfoot, thead, tr, th, td, article, aside, canvas, details, embed,figure, figcaption, footer, header, hgroup,menu, nav, output, ruby, section, summary, time, mark, audio, video{ margin: 0; padding: 0; border: 0; font-size: 100%; font: inherit; font-weight: normal; vertical-align: baseline; } /* HTML5 display-role reset for older browsers */ article, aside, details, figcaption, figure,footer, header, hgroup, menu, nav, section{ display: block; } ol, ul, li{ list-style: none; } blockquote, q{ quotes: none; } blockquote:before, blockquote:after, q:before, q:after{ content: ''; content: none; } table{ border-collapse: collapse; border-spacing: 0; } /* custom */ a{ color: #7e8c8d; text-decoration: none; -webkit-backface-visibility: hidden; } ::-webkit-scrollbar{ width: 5px; height: 5px; } ::-webkit-scrollbar-track-piece{ background-color: rgba(0, 0, 0, 0.2); -webkit-border-radius: 6px; } ::-webkit-scrollbar-thumb:vertical{ height: 5px; background-color: rgba(125, 125, 125, 0.7); -webkit-border-radius: 6px; } ::-webkit-scrollbar-thumb:horizontal{ width: 5px; background-color: rgba(125, 125, 125, 0.7); -webkit-border-radius: 6px; } html, body{ width: 100%; font-family: "Arial", "Microsoft YaHei", "黑体", "宋体", "微软雅黑", sans-serif; } body{ line-height: 1; -webkit-text-size-adjust: none; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); } html{ overflow-y: scroll; } /*清除浮动*/ .clearfix:before, .clearfix:after{ content: " "; display: inline-block; height: 0; clear: both; visibility: hidden; } .clearfix{ *zoom: 1; } /*隐藏*/ .dn{ display: none; }

index.html中引用:

3、引入ElementPlus 组件库

3.1、导入依赖包

npm i element-plus -D

第一种:全局挂载ElementPlus,在main.js中添加

第一种:按需导入组件

vue.config.js中引入(按需导入方式),添加如下配置

const { defineConfig } = require('@vue/cli-service');const AutoImport = require('unplugin-auto-import/webpack');const Components = require('unplugin-vue-components/webpack');const { ElementPlusResolver } = require('unplugin-vue-components/resolvers');module.exports = defineConfig({transpileDependencies: true,//关闭eslint校验lintOnSave: false,configureWebpack: {plugins: [AutoImport({resolvers: [ElementPlusResolver()],}),Components({resolvers: [ElementPlusResolver()],}),],}})

在页面中使用ElementPlus组件


效果:

3、创建登录页面

在view下新建Login.vue文件

<template><div class="container" :class="{ 'sign-up-mode': signUpMode }"><!-- form表单容器 --><div class="form-container"><div class="signin-signup"><!-- 登录 --><el-formref="ruleFormRef":model="loginUser":rules="rules"label-width="100px"class="login-form sign-in-form"><el-form-item label="邮箱" prop="email"><el-input v-model="loginUser.email" placeholder="Enter Email..." /></el-form-item><el-form-item label="密码" prop="password"><el-inputv-model="loginUser.password"type="password"placeholder="Enter Password..."/></el-form-item><el-form-item><el-button type="primary" class="submit-btn" @click="submitForm(ruleFormRef)">提交</el-button></el-form-item><!-- 找回密码 --><el-form-item><p

4、封装并使用 Axios

4.1、安装Axios

npm i axios

4.2、安装NProgress顶部进度条

npm i –save-dev @types/nprogress

4.3、封装请求拦截

在 src 目录新建 utils 文件夹,再新建 requestUtil.ts 文件,写上以下代码

import axios from 'axios'import Nprogress from 'nprogress'import 'nprogress/nprogress.css'import { ElMessage } from 'element-plus'const http = axios.create({baseURL: 'http://localhost:9000',timeout: 300 * 1000, // 请求超时时间设置为300秒})const NETWORK_ERROR = '网络错误,请联系开发人员'/** * 请求拦截器 */http.interceptors.request.use((req) => {console.log('请求拦截器 =>', req)Nprogress.start()return req;}, (error) => {Nprogress.done()return Promise.reject(error);});/** * 响应拦截器 */http.interceptors.response.use(function (res) {console.log('响应拦截器 =>', res)Nprogress.done()if (res.status == 200) {return res.data} else {ElMessage.error((NETWORK_ERROR))return Promise.reject(NETWORK_ERROR)}});export default http

4.4、前端设置跨域

在vue.config.js中配置如下代码:

const { defineConfig } = require('@vue/cli-service');// const AutoImport = require('unplugin-auto-import/webpack');// const Components = require('unplugin-vue-components/webpack');// const { ElementPlusResolver } = require('unplugin-vue-components/resolvers');module.exports = defineConfig({transpileDependencies: true,//关闭eslint校验lintOnSave: false,// ElementPlus按需导入方式// configureWebpack: {// plugins: [// AutoImport({// resolvers: [ElementPlusResolver()],// }),// Components({// resolvers: [ElementPlusResolver()],// }),// ],// }devServer: {open: true,host: 'localhost',port: 8080,https: false,// 设置跨域proxy: {'/api': {target: 'http://localhost:9000',ws: true,changeOrigin: true,pathRewrite: {'^api': ''}}}}})

4.5、配置接口api

在src目录下创建api文件夹,里面创建index.ts

import http from '@/utils/requestUtils' export default {/** * 根据用户邮箱、密码查询用户信息 */getUserPassword(data: any) {return http.post('/api/getUserPassword',data,{headers: {'Content-Type': 'application/json'},})}, /** * 保存用户信息 */saveUser(data: any) {return http.post('/api/saveUser',data,{headers: {'Content-Type': 'application/json'},})},}

4.6、将http请求全局封装

在 main.ts 文件引入HTTP请求工具并配置为全局方法

import { createApp } from 'vue'import App from './App.vue'import router from './router'import store from './store'import ElementPlus from 'element-plus'import 'element-plus/dist/index.css'import axios from 'axios'import apiServe from '@/api'const app = createApp(App)app.use(store)app.use(router)app.use(ElementPlus)app.mount('#app')app.config.globalProperties.$http = apiServeapp.config.globalProperties.$axios = axios

二、后端项目

1、检查JDK和maven的安装版本

在cmd输入 java -version
和mvn -v检查对应的安装情况

2、创建springboot项目

通过idea的spring initializr创建工程,不选择maven而是选择spring initializr快捷创建。然后去勾选相关依赖。

3、创建springboot项目成功

项目创建成功

4、配置maven和maven库

配置本地maven库

5、加载maven库

6、创建application.yml

在resources下面新建application.yml,并配置数据库名,密码,以及端口,端口尽量不要使用8080,避免和前端端口相同了


注释掉另外一个配置

# mysqlspring:datasource:#MySQL配置driverClassName:com.mysql.cj.jdbc.Driverurl: jdbc:mysql://localhost:3306/easyproject" />: rootpassword: 920724mybatis:mapper-locations: classpath:mapper/*.xmltype-aliases-package: com.example.demo.modelserver:port: 9000

7、运行项目


项目运行成功,端口9000

8、新建WebConfig文件处理跨域

创建utils文件夹,在utils文件夹下创建WebConfig,并添加以下配置

package com.springboot.userlogin.springbootdemo.utils;import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.config.annotation.CorsRegistry;import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;// 使用注解说明是全局配置类@Configurationpublic class WebConfig extends WebMvcConfigurerAdapter { // 继承跨域请求的类@Overridepublic void addCorsMappings(CorsRegistry registry) { // 跨域处理的方法registry.addMapping("/**") // 任意访问都允许跨域.allowedOrigins("http://localhost:8080", "null") // 跨域来源.allowedMethods("POST", "GET", "PUT", "OPTIONS", "DELETE") // 跨域请求类型.maxAge(3600) // 超时时间.allowCredentials(true); // 允许携带信息}}

alt+insert快捷键可以弹出

9、使用idea连接mysql

mysql安装配置方法可以参照我写的另外一个文档:
https://blog.csdn.net/m0_47791238/article/details/134811414?spm=1001.2014.3001.5501



输入mysql用户名和密码:

10、在pom文件添加lombok依赖

目的:为了使用@Data注解

<dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>1.18.24</version> </dependency>

11、创建bean文件夹,用于放置实体对象

在项目中创建bean文件夹,新建user实体类,使用Data注解,创建构造方法和get\set方法

package com.springboot.userlogin.springbootdemo.bean;import lombok.Data;@Datapublic class User {private int id;private String username;private String password;private String email;private String role;private boolean state;//public User() {//}//public User(String username, String password, String email, String role, boolean state) {//this.username = username;//this.password = password;//this.email = email;//this.role = role;//this.state = state;//}////public int getId() {//return id;//}////public String getUsername() {//return username;//}////public String getPassword() {//return password;//}////public String getEmail() {//return email;//}////public String getRole() {//return role;//}////public boolean getState() {//return state;//}////public void setId(int id) {//this.id = id;//}////public void setUsername(String username) {//this.username = username;//}////public void setPassword(String password) {//this.password = password;//}////public void setEmail(String email) {//this.email = email;//}////public void setRole(String role) {//this.role = role;//}////public void setState(boolean state) {//this.state = state;//}}

12、查看构造成功成功的实体对象

快捷键 alt + 7

13、创建controller接口

import org.springframework.web.bind.annotation.PostMapping;import org.springframework.web.bind.annotation.RequestBody;import org.springframework.web.bind.annotation.RestController;@RestControllerpublic class LoginController {@AutowiredUserDao userDao;@PostMapping("/api/getUserPassword") // @RequestMapping注解创建接口public String userLogin(@RequestBody User user) { // @RequestBody注解方便找到user实体System.out.println("User : " + user);String str = "error";int count = userDao.getUserByMassage(user.getEmail(), user.getPassword());if (count > 0) {str = "ok";}return str;}}

14、创建dao接口

package com.springboot.userlogin.springbootdemo.dao;import org.apache.ibatis.annotations.Mapper;import org.apache.ibatis.annotations.Param;import org.springframework.stereotype.Repository;@Repository@Mapperpublic interface UserDao {int getUserByMassage(@Param("email") String email, @Param("password") String password);}

15、创建mapper映射文件

在resources下面创建mapper文件夹,用于存放数据库的映射文件
在mapper文件夹下新建UserMapper.xml

<" />="1.0" encoding="UTF-8" ?><!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd"><!--对应dao层接口文件的目录--><mapper namespace="com.springboot.userlogin.springbootdemo.dao.UserDao"><!--id值为UserDao接口方法名; --><select id="getUserByMassage" resultType="java.lang.Integer"> SELECT count(id) FROM easyUser WHERE email=#{email} AND password=#{password}</select></mapper>

三、测试前后端功能

1、前端页面接口请求

2、后端控制台日志打印
