---

一、创建vue项目并运行

--使用管理员身份运行VSCode,然后在终端打开dos命令行界面

--设置国内的镜像

#经过下面的配置，以后所有的 npm install 都会经过淘宝的镜像地址下载
npm config set registry https://registry.npm.taobao.org

--安装vue-cli的插件\全局安装

npm install vue-cli -gnpm install -g @vue/cli-init  或者  npm install -g '@vue/cli-init'

--安装webpack的插件\全局安装

npm install -g webpack

注意：shell命令策略设置【当命令执行失败时操作、没有问题就不用管、继续下一步即可】

像这种都是策略问题，用管理员打开vscode，然后设置策略
get-ExecutionPolicy执行set-ExecutionPolicy RemoteSigned  然后 get-ExecutionPolicy，显示RemoteSigned就是ok了set-ExecutionPolicy RemoteSigned

--通过vue-cli脚手架来创建一个项目 

vue init webpack vaccinum-vue

--切换到当前项目路径下、然后在启动vue项目测试【npm run dev】

cd vaccinum-vuenpm run dev

---

二、vue-cli中的路由使用

路由主要是实现页面跳转【实际上是请求地址映射vue页面】

--在components中创建两个vue页面文件

<template><div class="hello"><h2>Demo1111 Links</h2></div>
</template>

<template><div class="hello"><h2>Demo222 Links</h2></div>
</template>

--在router路由配置文件中配置页面的访问地址

import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
Vue.use(Router)
export default new Router({routes: [{path: '/',name: 'HelloWorld',component: HelloWorld},{path: '/demo1',name: 'demo1',component: ()=>import('@/components/demo1')},{path: '/demo2',name: 'demo2',component: ()=>import('@/components/demo2')}]
})

--在App.vue中提供两个链接，然后测试

<!--  两个链接 --><router-link to="/demo1">demo1</router-link><router-link to="/demo2">demo2</router-link><!--  两个链接 -->

---

三、element-ui框架、实现页面布局以及vue-路由

 --布局效果图

--element-ui网站【参考学习】

https://element.eleme.cn/#/zh-CN/component/installation

--ctrl+c 结束程序，然后执行命令下载element-ui依赖

--添加elementui依赖

--在vue项目目录下使用下面命令,添加ElementUI 依赖

npm i element-ui -S

 --在src中的main.js中配置、导入element-ui组件及样式文件

// 导入ElementUI
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
Vue.use(ElementUI);//在vue使用ElementUI

--创建页面

--页面布局：在components下创建Layout.vue

<template><div><!-- 头部 --><Header /><!-- 主题 --><div style="display: flex"><!-- 主题-左边 --><Aside /><!-- 主题-右边  flex: 1 自适应布局 --><router-view style="flex: 1" /></div></div>
</template><!-- js --><script>
// 导入组件
import Header from "@/components/Header";
import Aside from "@/components/Aside";export default {name: "Layout",//  使用哪些组件components: {Aside,Header,},
};
</script>

 --页面布局：在components下创建Header.vue文件

<template><divstyle="height: 50px;line-height: 50px;border-bottom: 1px solid #ccc;display: flex;"><divstyle="width: 200px;padding-left: 30px;font-weight: bold;color: dodgerblue;">管理系统</div><div style="flex: 1"></div><div style="width: 150px"><el-dropdown @command="handleCommand"><span class="el-dropdown-link"><el-avatarsrc="https://cube.elemecdn.com/0/88/03b0d39583f48206768a7534e55bcpng.png"></el-avatar>admin<i class="el-icon-arrow-down el-icon--right"></i></span><el-dropdown-menu slot="dropdown"><el-dropdown-item command="a">个人信息</el-dropdown-item><el-dropdown-item command="b">退出系统</el-dropdown-item></el-dropdown-menu></el-dropdown></div></div>
</template><script>
import router from "@/router";export default {name: "Header",data() {return {name: "未登录",};},created() {},methods: {handleCommand(command) {},},
};
</script>

--页面布局：在components下创建Aside.vue文件

<template><div><el-menustyle="width: 250px; min-height: calc(100vh - 50px)"default-active="2"class="el-menu-vertical-demo"@open="handleOpen"@close="handleClose":default-openeds="[path]"router><el-submenu index="1"><template slot="title"><i class="el-icon-location"></i><span>导航一</span></template><el-menu-item-group><template slot="title">分组一</template><el-menu-item index="/list">选项1</el-menu-item><el-menu-item index="1-2">选项2</el-menu-item></el-menu-item-group><el-menu-item-group title="分组2"><el-menu-item index="1-3">选项3</el-menu-item></el-menu-item-group><el-submenu index="1-4"><template slot="title">选项4</template><el-menu-item index="1-4-1">选项1</el-menu-item></el-submenu></el-submenu><el-menu-item index="2"><i class="el-icon-menu"></i><span slot="title">导航二</span></el-menu-item><el-menu-item index="3" disabled><i class="el-icon-document"></i><span slot="title">导航三</span></el-menu-item><el-menu-item index="4"><i class="el-icon-setting"></i><span slot="title">导航四</span></el-menu-item></el-menu></div>
</template><script>
export default {data() {return {//path变量path: this.$route.path,};},methods: {handleOpen(key, keyPath) {console.log(key, keyPath);},handleClose(key, keyPath) {console.log(key, keyPath);},},
};
</script>

 --把App.vue的图标注释掉

--路由：在router下index.js修改请求映射

import Vue from 'vue'
import Router from 'vue-router'
//导入局部的页面Layout
import Layout from '@/components/Layout'
Vue.use(Router)
export default new Router({routes: [// 也就是--   / 映射到了 Layout的页面{path: '/',name: 'Layout',component: Layout}]
})

--重新启动前端项目-访问即可

---

四、前端登录页面

--1、在components下创建Login.vue

<template><div class="login"><!-- 登录表单 v-model --><div class="login-form"><!-- :gutter="20" --><el-row :gutter="20"><el-col :span="12"><div><imgsrc="../assets/logo.png"alt=""style="position: relative;left: -100px;width: 250px;height: 85px;"/></div><div style="position: relative; left: 50px"><img src="../assets/icon-big.png" alt="" /></div></el-col><el-col :span="2"></el-col><el-col :span="10"><!-- 登录的form组件【提交的信息】 --><el-formref="loginForm":model="loginForm"style="margin-left: 150px; margin-top: 150px"><el-form-item><el-tabsv-model="roleType"@tab-click="selectRole":stretch="true"><el-tab-pane label="用户登录" name="用户"></el-tab-pane><el-tab-pane label="医生登录" name="医生"></el-tab-pane><el-tab-pane label="管理员登录" name="管理员"></el-tab-pane></el-tabs></el-form-item><el-form-item prop="name" v-if="roleType === '管理员'"><el-inputprefix-icon="el-icon-user"v-model="loginForm.name"type="text"placeholder="账号"></el-input></el-form-item><el-form-item prop="phone" v-if="roleType !== '管理员'"><el-inputprefix-icon="el-icon-user"v-model="loginForm.phone"type="text"placeholder="账号"></el-input></el-form-item><el-form-item prop="password"><el-inputprefix-icon="el-icon-lock"v-model="loginForm.password"autocomplete="off"show-passwordplaceholder="密码"></el-input></el-form-item><el-form-item prop="code" v-if="captchaEnabled"><el-inputv-model="loginForm.code"placeholder="请输入验证码"style="width: 63%"></el-input><div class="login-code"><el-avatarshape="square"style="width: 100px":src="codeUrl"></el-avatar></div></el-form-item><el-form-item style="width: 100%"><el-buttonsize="medium"type="primary"style="width: 100%; background-color: rgb(77, 167, 252)"@click="doLogin()"><span style="font-size: 20px">登 录</span></el-button></el-form-item><el-form-item style="width: 100%"><el-buttonsize="medium"type="primary"style="width: 100%; background-color: rgb(77, 167, 252)"v-if="roleType == '用户'"@click="registerFormVisible = true"><span style="font-size: 20px">注 册</span></el-button></el-form-item></el-form><!-- 登录的form组件【提交的信息】 --></el-col></el-row></div><!-- 用户注册表单 --><el-dialogtitle="用户注册":visible.sync="registerFormVisible":close-on-click-modal="false"><el-formlabel-position="top":model="registerForm"status-iconref="registerForm"label-width="100px"class="demo-registerForm"><!-- 头像 --><el-form-item label="头像" prop="image"><el-uploadclass="avatar-uploader"action="http://localhost:80/vaccinum/common/upload":show-file-list="false":on-success="handleAvatarSuccess":before-upload="beforeAvatarUpload"><img v-if="imageUrl" :src="imageUrl" class="avatar" /><i v-else class="el-icon-plus avatar-uploader-icon"></i></el-upload><!-- 隐藏输入字段，用来存储图片的文件名 --><input type="hidden" name="avatar" v-model="registerForm.image" /></el-form-item><!-- 用户名\性别 --><el-row :gutter="20"><el-col :span="12"><el-form-item label="用户名" prop="name"><el-inputtype="text"v-model="registerForm.name"autocomplete="off"></el-input></el-form-item></el-col><el-col :span="12"><el-form-item label="性别" prop="sex"><el-inputtype="text"v-model="registerForm.sex"autocomplete="off"></el-input></el-form-item></el-col></el-row><!-- 年龄\身份证号 --><el-row :gutter="20"><el-col :span="12"><el-form-item label="年龄" prop="age"><el-inputtype="text"v-model="registerForm.age"autocomplete="off"></el-input></el-form-item></el-col><el-col :span="12"><el-form-item label="身份证号" prop="codeid"><el-inputtype="text"v-model="registerForm.codeid"autocomplete="off"></el-input></el-form-item></el-col></el-row><!-- 密码\密码 --><el-row :gutter="20"><el-col :span="12"><el-form-item label="密 码" prop="password"><el-inputtype="password"v-model="registerForm.password"autocomplete="off"></el-input></el-form-item></el-col><el-col :span="12"><el-form-item label="确认密码" prop="password_check"><el-inputtype="password"v-model="registerForm.password_check"autocomplete="off"></el-input></el-form-item></el-col></el-row><!-- 手机号\地址 --><el-row :gutter="20"><el-col :span="12"><el-form-item label="手机号" prop="phone"><el-inputtype="text"v-model="registerForm.phone"autocomplete="off"></el-input></el-form-item></el-col><el-col :span="12"><el-form-item label="地址" prop="address"><el-inputtype="text"v-model="registerForm.address"autocomplete="off"></el-input></el-form-item></el-col></el-row><el-form-item><el-button type="primary" @click="registerSumbit">提交</el-button><el-button@click="registerFormVisible = false;this.registerForm = {name: '',password: '',password_check: '',phone: '',};">取消</el-button></el-form-item></el-form></el-dialog><!-- 用户注册表单 --><!-- 底部 --><div class="el-login-footer"><span>Copyright © 2018-2022 gec All Rights Reserved.</span></div><!-- 底部 --></div>

</style>

--2、在路由index.js中配置根目录访问登录页面、然后修改首页的

import Vue from 'vue'
import Router from 'vue-router'
//导入局部的页面Layout
import Layout from '@/components/Layout'
import Login from '@/components/Login'
Vue.use(Router)
export default new Router({routes: [// 也就是--   / 映射到了 Login的页面{path: '/',name: 'Login',   component: Login},{path: '/Layout',name: 'Layout',   component: Layout}]
})

 --3、替换src中的assets文件中的图片

---

五、user登录后端接口完善【后端】

--1、在UserController中提供登录的处理方法、接收数据，响应json格式的数据

//json 的解析工具
ObjectMapper jsonTool = new ObjectMapper();// http://localhost:8085/user/loginUser?phone=sdfsdf&password=xxxx
//    定义user的登录查询的请求接口【根据手机号码和密码进行登录】
@RequestMapping("/loginUser")
public String loginUser(String phone,String password) throws JsonProcessingException {// map集合-结果集HashMap result =new HashMap();//調用业务层的查询方法，根据手机号码和密码进行查询QueryWrapper<User> wrapper = new QueryWrapper<>();wrapper.eq("phone",phone).eq("password",password);//条件查询，获取一个对象User user = userService.getOne(wrapper);//业务逻辑的判断if(user!=null){//登录成功result.put("flag",true);result.put("user",user);result.put("role","user");}else{//登录失败result.put("flag",false);result.put("message","用戶名或密碼錯誤！！！");}//返回json格式的数据return jsonTool.writeValueAsString(result);
}

--2、启动项目然后测试

http://localhost:8085/user/loginUser?phone=123451645602&password=123sdfsdfsdfsd

---

六、user登录前端-请求工具-请求发起【前端】

--结束前端程序ctrl+c

--执行命令、安装axios和cookie依赖

npm install axios --save
npm install --save js-cookie

--在src下创建utils文件夹、并创建request.js文件

import axios from 'axios'
import router from "@/router";
import qs from "qs"
import Cookies from "js-cookie";
axios.defaults.withCredentials=true //让ajax请求携带cookie
//1、目的是封装请求对象  2、目的对请求和响应数据进行格式
// 创建对象
const request = axios.create({baseURL: 'http://localhost:8085',  // 注意！！ 这里是全局统一加上了 baseURL 前缀，timeout: 5000
})// request 拦截器
request.interceptors.request.use(config => {//对请求的数据进行处理if (config.method != 'get') {config.data = qs.stringify(config.data);}// post请求方式的content格式config.headers['content-Type'] = 'application/x-www-form-urlencoded';//允许通过访问return config;},error => {console.log('err' + error) // for debugreturn Promise.reject(error)}
)// response 拦截器
// 可以在接口响应后统一处理结果
request.interceptors.response.use(response => {let res = response.data;// 如果是返回的文件if (response.config.responseType === 'blob') {return res}// 兼容服务端返回的字符串数据if (typeof res === 'string') {res = res ? JSON.parse(res) : res}return res;},error => {console.log('err' + error) // for debugreturn Promise.reject(error)}
)export default request

--修改Login.vue中的登录请求处理函数、发起异步请求

//注意导入请求工具类和cookie
import Cookies from "js-cookie";
import request from "@/utils/request.js";

doLogin() {//通过请求对象发起一个异步请求操作【axios】request.post("/user/loginUser", this.loginForm) //第一个参数是请求地址、第二个参数提交的数据 //回调函数\获取服务器响应的结果.then((res) => {//如果成功flagif (res.flag == true) {this.$message.success("登录成功！"); //把user信息、角色信息存放在cookie中Cookies.set("user", JSON.stringify(res.user), { expires: 0.3 });Cookies.set("role", res.role, { expires: 0.3 }); //通过路由跳转、登录成功后跳转到首页router.push("/Layout");} else {//登录失败提示信息this.$message.error(res.message);}});},

--点击登录按钮进行测试、请求是成功发起的，但是发现跨域拦截:

---

七、请求的跨域-访问策略

--后端项目中创建config包，然后创建配置类提供跨域访问策略：

import org.springframework.stereotype.Component;import javax.servlet.*;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;//定义拦截器允许跨域访问
@Component
public class UrlCorsConfiguration implements Filter {public void doFilter(ServletRequest req, ServletResponse res,FilterChain chain) throws IOException, ServletException {HttpServletResponse response = (HttpServletResponse) res;//        允许跨域访问的地址【前端项目部署的地址】response.setHeader("Access-Control-Allow-Origin", "http://localhost:8080");//允许跨域的请求方法GET, POST, HEAD 等response.setHeader("Access-Control-Allow-Methods", "POST, GET, PUT, OPTIONS, DELETE");//重新预检验跨域的缓存时间 (s)response.setHeader("Access-Control-Max-Age", "3600");//允许跨域的请求头response.setHeader("Access-Control-Allow-Headers", "x-requested-with, Content-Type");//是否携带cookieresponse.setHeader("Access-Control-Allow-Credentials", "true");// 设置响应的类型及字符集编码response.setContentType("text/json;charset=utf-8");//设置响应的中文编码chain.doFilter(req, res);}public void init(FilterConfig filterConfig) {}public void destroy() {}}

--重启后端项目，然后发起请求查看

---

八、完善项目的页面布局、导航菜单以及权限划分

--替换Aside.vue后端项目

<template><div><el-menustyle="width: 250px; min-height: calc(100vh - 50px);padding-top: 10px;"default-active="2"class="el-menu-vertical-demo"@open="handleOpen"@close="handleClose":default-openeds="[path]"router><el-submenu index="1" v-if="role == 'manager'"><template slot="title"><i class="el-icon-s-management"></i><!-- font-family:'Franklin Gothic Medium', 'Arial Narrow', Arial, sans-serif;" --><span style="font-size: 17px; font-weight: bold;font-family:'苹方'">管理员模块</span></template><el-menu-item-group><el-menu-item index="/Layout/adminList"><i class="el-icon-link"></i>管理员列表</el-menu-item></el-menu-item-group></el-submenu><el-submenu index="2"><template slot="title"><i class="el-icon-first-aid-kit"></i><span style="font-size: 17px; font-weight: bold;font-family:'苹方'">医生模块</span></template><el-menu-item-group><!-- <i class="icon_line"></i> --><el-menu-item index="/Layout/doctorList"><i class="el-icon-link"></i> 医生列表</el-menu-item><el-menu-itemindex="/Layout/registration"v-if="role == 'manager' || role == 'doctor' || role == 'user'"><i class="el-icon-link"></i>挂号记录</el-menu-item><el-menu-item index="/Layout/vaccineRecord" v-if="role != 'doctor'"><i class="el-icon-link"></i>接种记录</el-menu-item></el-menu-item-group></el-submenu><el-submenu index="3" v-if="role == 'manager' || role == 'user'"><template slot="title"><i class="el-icon-user"></i><span style="font-size: 17px; font-weight: bold;font-family:'苹方'">用户模块</span></template><el-menu-item-group><el-menu-item index="/Layout/userList" v-if="role == 'manager'"><i class="el-icon-link"></i>用户列表</el-menu-item><el-menu-item index="/Layout/userRegis" v-if="role == 'user'"><i class="el-icon-link"></i>预约挂号</el-menu-item></el-menu-item-group></el-submenu><el-submenu index="4"><template slot="title"><i class="el-icon-office-building"></i><span style="font-size: 17px; font-weight: bold;font-family:'苹方'">医院模块</span></template><el-menu-item-group><el-menu-item index="/Layout/hosList"><i class="el-icon-link"></i>医院列表</el-menu-item><el-menu-item index="/Layout/deptList"><i class="el-icon-link"></i>科室列表</el-menu-item></el-menu-item-group></el-submenu><el-submenu index="5"><template slot="title"><i class="el-icon-office-building"></i><span style="font-size: 17px; font-weight: bold;font-family:'苹方'">疫苗模块</span></template><el-menu-item-group><el-menu-item index="/Layout/vaccineType"><i class="el-icon-link"></i>疫苗种类</el-menu-item><el-menu-item index="/Layout/vaccine"><i class="el-icon-link"></i>疫苗信息</el-menu-item><el-menu-item index="/Layout/appVaccineList"><i class="el-icon-link"></i>可预约疫苗</el-menu-item></el-menu-item-group></el-submenu></el-menu></div>

export default {name: "Header",data() {return {name: "未登录",image: "",role: "",};},created() {//获取登录用户信息var userJson = JSON.parse(Cookies.get("user"));this.name = userJson.name;this.image = userJson.image;this.role = Cookies.get("role");},methods: {handleCommand(command) {if (command == "b") {Cookies.remove("user");//跳转到登录router.push("/login");} else {//跳转到个人信息router.push("/Layout/personalInfo");}},},
};
</script>

--修改后端UserController中-的登录请求要返回user的对象数据、用户的角色

// 在结果集中保存user对象以及角色信息
result.put("user", user);
result.put("role", "user");

 --登录页面的登录函数中存储user和role角色信息

--重新登录测试即可

---

九、实现疫苗分类的查询及分析流程

--后端：VaccineType实体类中添加主键变量

/*** 主键*/
@TableId(type = IdType.AUTO)
private Integer id;

--后端：VaccineTypeController中定义查询请求接口

@RestController
@RequestMapping("/vaccinetype")
public class VaccineTypeController {//jsonObjectMapper json = new ObjectMapper();//service@AutowiredIVaccineTypeService typeService;// 测试 http://localhost:8085/vaccinetype/query//查询分类、响应json数据【键值对的数据】@RequestMapping("/query")public String query() throws JsonProcessingException {//结果的存放集合HashMap result = new HashMap();//    1\调用业务层方法执行查询操作List<VaccineType> list = typeService.list();//    2\在结果集中存放list集合result.put("list", list);//   返回json数据return json.writeValueAsString(result);}}

--前端：在src下创建type文件夹，然后创建TypeList.vue

--前端：从element-ui中获取组件代码、提供请求操作和修改table中的字段名

<template><el-table :data="tableData" stripe style="width: 100%"><el-table-column prop="id" label="编号"> </el-table-column><el-table-column prop="name" label="名称"> </el-table-column><el-table-column prop="remark" label="描述"> </el-table-column></el-table>
</template><script>
import request from "@/utils/request.js";
export default {data() {return {tableData: [],};},// 页面中的vue对象创建成功后触发created() {//发起查询请求request.get("/vaccinetype/query") //第一个参数是请求地址、第二个参数提交的数据 //回调函数\获取服务器响应的结果.then((res) => {this.tableData = res.list;});},
};
</script>

--前端：修改路由、在Layout路径下配置子url的映射【router中的index.js文件】

import Vue from 'vue'
import Router from 'vue-router'
//导入局部的页面Layout
import Layout from '@/components/Layout'
import Login from '@/components/Login'
Vue.use(Router)
export default new Router({routes: [// 也就是--   / 映射到了 Login的页面{path: '/',name: 'Login',component: Login},// 页面布局的映射{path: '/Layout',name: 'Layout',component: Layout,children: [{path: 'vaccineType',//   --> /Layout/vaccineTypename: 'vaccineType',component: ()=>import('@/type/TypeList')},],}]
})

---

十、疫苗分类--页面完善、以及添加、修改及删除实现

--后端：在VaccineTypeController中提供删除、添加和修改的请求接口

@RestController
@RequestMapping("/vaccinetype")
public class VaccineTypeController {//依賴VaccineType业务层对象@Autowired //自动注入IVaccineTypeService typeService;//json 的解析工具ObjectMapper jsonTool = new ObjectMapper();// http://localhost:8085/vaccinetype/query//    定义查询的请求接口@RequestMapping("/query")public String query(String phone,String password) throws JsonProcessingException {// map集合-结果集HashMap result =new HashMap();//調用业务层的查询方法List<VaccineType> list = typeService.list();result.put("list",list);//返回json格式的数据return jsonTool.writeValueAsString(result);}// http://localhost:8085/vaccinetype/update//    定义修改的请求接口@RequestMapping("/update")public String update(VaccineType type) throws JsonProcessingException {// map集合-结果集HashMap result =new HashMap();//調用业务层的查询方法boolean update = typeService.updateById(type);result.put("flag",update);//返回json格式的数据return jsonTool.writeValueAsString(result);}// http://localhost:8085/vaccinetype/insert//    定义添加的请求接口@RequestMapping("/insert")public String insert(VaccineType type) throws JsonProcessingException {// map集合-结果集HashMap result =new HashMap();//調用业务层的查询方法boolean insert = typeService.save(type);result.put("flag",insert);//返回json格式的数据return jsonTool.writeValueAsString(result);}// http://localhost:8085/vaccinetype/insert//    定义刪除的请求接口@RequestMapping("/delete")public String delete(Integer id) throws JsonProcessingException {// map集合-结果集HashMap result =new HashMap();//調用业务层的查询方法boolean delete = typeService.removeById(id);result.put("flag",delete);//返回json格式的数据return jsonTool.writeValueAsString(result);}}

--替换TypeList.vue页面即可、效果如下：
