vue2+element+spring管理界面
目前这家公司前端用的是vue框架,由于在之前的公司很少涉及到前端内容,对其的了解也只是会使用js和jquery,所以..慢慢来吧。
在此之前需要先了解vue的大致语法和规则，可先前往官方文档进行学习https://cn.vuejs.org/v2/guide/
1.搭建vue工程
使用vue一般有直接引入vue.js方式,或者使用node.js进行构建,因为大部分的教程都是围绕node.js来展开的,所以这儿也使用node。
步骤1.下载node.js并安装,一般安装完成后会环境变量已经配置好,网上此类教程很多,不作赘述
步骤2.使用node.js创建vue工程
2.1安装vue脚手架
npm install –global vue-cli
2.2创建vue工程
vue init webpack my-project
这儿的选项
2.3创建好之后进入工程目录执行npm install安装所需要的依赖
2.4执行npm run dev启动工程，默认地址为localhost:8080，打开看到vue主页表明工程创建成功
同时创建好的工程目录大致如下
2.主要文件说明
引入需要的包
npm install --save axios //主要用来发送请求，可理解为ajax
npm install element-ui -S //一个ui框架
npm install qs -S //包装传回后台的数据防止接收不到
npm install vue-router //vue路由
完成后可以在package.json中可以查看到项目依赖
3.代码详细
3.1 src/main.js
1 // The Vue build version to load with the `import` command
2 // (runtime-only or standalone) has been set in webpack.base.conf with an alias.
3 import Vue from 'vue'
4 import App from './App'
5 import router from './router'
6
7 //引入elemen-u控件
8 import ElementUI from 'element-ui'
9 import 'element-ui/lib/theme-chalk/index.css'
10 Vue.config.productionTip = false
11 //使用use命令后才起作用
12 Vue.use(ElementUI)
13
14 /* eslint-disable no-new */
15 new Vue({
16 el: '#app',
17 router,
18 components: { App },
19 template: '<App/>'
20 })
3.2 src/router/index.js
1 import Vue from 'vue'
2 import Router from 'vue-router'
3 //使用懒加载的方式来引入,只有路由被访问的时候才加载
4 import home from '@/components/home'
5 const loginpage = resolve => require(['@/components/Login'],resolve)
6
7 Vue.use(Router)
8 let router = new Router({
9 routes: [
10 {
11 path:'/',
12 name :'login',
13 component:loginpage
14 },
15 {
16 path:'/login',
17 name :'login',
18 component:loginpage
19 },
20 {
21 path:'/home',
22 name :'home',
23 component:home
24 }
25 ]
26 })
27 //对每次访问之前都要先看是否已经登录
28 router.beforeEach((to,from,next)=>{
29 if(to.path.startsWith('/login')){
30 window.sessionStorage.removeItem('access-token');
31 next();
32 }else{
33 let token = window.sessionStorage.getItem('access-token');
34 if(!token){
35 //未登录 跳回主页面
36 next({path:'/login'});
37 }else{
38 next();
39 }
40 }
41
42 });
43
44
45 export default router
3.3在src下创建api文件夹，进入文件夹后创建api.js与index.js
api.js
//进行远程调用
import axios from 'axios'
//包装param参数
import qs from 'qs'
// 声明基础访问地址
axios.defaults.baseURL = 'http://localhost:8081'
//声明一个调用方法
export const requestLogin = params => {return axios.post('/user/login',qs.stringify(params)).then(res => res.data)}
index.js
import * as api from './api' export default api
3.4在src/components下创建登录组件Login.vue

4运行项目
在项目目录下执行以下命令并访问localhost:8080
npm install
npm run dev
5.java编写后台api
创建mavevn项目，引入springboot与数据库的相关的包，pom文件如下
1 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 2 <modelVersion>4.0.0</modelVersion> 3 <groupId>com.megalith</groupId> 4 <artifactId>vtpj</artifactId> 5 <version>0.0.1-SNAPSHOT</version> 6 <name>vtpj</name> 7 <description>vtpj</description> 8 9 10 <parent> 11 <groupId>org.springframework.boot</groupId> 12 <artifactId>spring-boot-starter-parent</artifactId> 13 <version>2.0.1.RELEASE</version> 14 <relativePath /> <!-- lookup parent from repository --> 15 </parent> 16 17 <properties> 18 <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 19 <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> 20 <java.version>1.8</java.version> 21 </properties> 22 23 <dependencies> 24 <dependency> 25 <groupId>org.springframework.boot</groupId> 26 <artifactId>spring-boot-starter-actuator</artifactId> 27 </dependency> 28 <dependency> 29 <groupId>org.springframework.boot</groupId> 30 <artifactId>spring-boot-starter-cache</artifactId> 31 </dependency> 32 <dependency> 33 <groupId>org.springframework.boot</groupId> 34 <artifactId>spring-boot-starter-jdbc</artifactId> 35 </dependency> 36 <dependency> 37 <groupId>org.springframework.boot</groupId> 38 <artifactId>spring-boot-starter-web</artifactId> 39 </dependency> 40 <dependency> 41 <groupId>org.springframework.boot</groupId> 42 <artifactId>spring-boot-starter-test</artifactId> 43 <scope>test</scope> 44 </dependency> 45 <dependency> 46 <groupId>org.springframework.boot</groupId> 47 <artifactId>spring-boot-devtools</artifactId> 48 <optional>true</optional> 49 </dependency> 50 <dependency> 51 <groupId>org.apache.commons</groupId> 52 <artifactId>commons-lang3</artifactId> 53 </dependency> 54 <dependency> 55 <groupId>org.apache.commons</groupId> 56 <artifactId>commons-collections4</artifactId> 57 <version>4.1</version> 58 </dependency> 59 60 <!-- jdbc --> 61 <dependency> 62 <groupId>org.mybatis.spring.boot</groupId> 63 <artifactId>mybatis-spring-boot-starter</artifactId> 64 <version>1.1.1</version> 65 </dependency> 66 <dependency> 67 <groupId>mysql</groupId> 68 <artifactId>mysql-connector-java</artifactId> 69 <version>6.0.6</version> 70 </dependency> 71 </dependencies> 72 73 <repositories> 74 <repository> 75 <id>aliyun</id> 76 <name>aliyun</name> 77 <url>http://maven.aliyun.com/nexus/content/groups/public</url> 78 </repository> 79 </repositories> 80 81 <build> 82 <plugins> 83 <plugin> 84 <groupId>org.springframework.boot</groupId> 85 <artifactId>spring-boot-maven-plugin</artifactId> 86 </plugin> 87 </plugins> 88 89 <resources> 90 <resource> 91 <directory>src/main/java</directory> 92 <includes> 93 <include>**/*.properties</include> 94 <include>**/*.xml</include> 95 </includes> 96 <filtering>false</filtering> 97 </resource> 98 </resources> 99 100 </build> 101 </project>
配置application.properties数据库链接及其他配置
server.port=8081 #取消自动加载数据源 #spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration #配置数据源 mybatis.type-aliases-package=com.megalith.tjfx.bean spring.datasource.driverClassName = com.mysql.jdbc.Driver spring.datasource.url = jdbc:mysql://localhost:3306/tjfx?useUnicode=true&characterEncoding=utf-8&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC spring.datasource.username = root spring.datasource.password = root
项目目录大致如下
corseconfig.java内容如下，主要解决跨域访问不到地址的问题
1 package com.megalith.tjfx.config;
2
3 import org.springframework.context.annotation.Bean;
4 import org.springframework.context.annotation.Configuration;
5 import org.springframework.web.cors.CorsConfiguration;
6 import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
7 import org.springframework.web.filter.CorsFilter;
8
9 /**
10 *
11 * @ClassName: CorseConfig
12 * @Desc:
13 * @author: zhouming
14 * @date: 2018年8月7日 下午4:16:39
15 * @version 1.0
16 */
17 @Configuration
18 public class CorseConfig {
19
20
21 private CorsConfiguration buildConfig() {
22 CorsConfiguration corsConfiguration = new CorsConfiguration();
23 corsConfiguration.addAllowedOrigin("*");
24 corsConfiguration.addAllowedHeader("*");
25 corsConfiguration.addAllowedMethod("*");
26 corsConfiguration.setAllowCredentials(true);
27 return corsConfiguration;
28 }
29
30 @Bean
31 public CorsFilter corsFilter() {
32 UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
33 source.registerCorsConfiguration("/**", buildConfig());
34 return new CorsFilter(source);
35
36 }
37 }
启动类记得添加mybatis扫描
1 @EnableCaching
2 @SpringBootApplication
3 @MapperScan("com.megalith.tjfx.dao")
4 public class ApplicationContext {
5
6 public static void main(String[] args) {
7 SpringApplication.run(ApplicationContext.class, args);
8 }
9 }
编写相应api，然后启动项目后vue项目即可以与java进行开发
package com.megalith.tjfx.controller;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.UUID;
import org.apache.commons.lang3.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import com.megalith.tjfx.bean.User;
import com.megalith.tjfx.service.IUserService;
/**
*
* @ClassName: UserController
* @Desc: 用户注册的controller
* @author: zhouming
* @date: 2018年8月7日 下午1:43:16
* @version 1.0
*/
@RestController
@RequestMapping("/user")
public class UserController {
@Autowired
private IUserService userService;
@PostMapping("/login")
public Object loginUser(User user) {
Map<String,Object> result = new HashMap<String, Object>();
System.err.println(user);
if("admin".equals(user.getcUsername()) && "123456".equals(user.getcPwd())) {
result.put("code", 200);
result.put("msg", "登录成功");
result.put("token", "adminxxxx");
return result;
}
result.put("code", 500);
result.put("msg", "登录失败");
return result;
}
@PostMapping("/submit")
public Object submitUser(User user) {
Map<String,Object> result = new HashMap<String, Object>();
if(StringUtils.isBlank(user.getcId())) {
user.setcId(UUID.randomUUID().toString().replaceAll("-", ""));
userService.save(user);
}else{
userService.update(user);
}
result.put("success", true);
result.put("msg", "登录成功");
result.put("token", "adminxxxx");
return result;
}
@PostMapping("/userlist")
public List<User> userList(String filter){
return userService.listUser(filter);
}
@PostMapping("/delete")
public Map<String, Object> delete(String userId){
Map<String,Object> result = new HashMap<String, Object>();
if(StringUtils.isNotBlank(userId)) {
userService.deleteByPrimarykey(userId);
result.put("success", true);
}else {
result.put("success", false);
}
return result;
}
}

5.项目部署
Nginx部署我也还在琢磨当中，下一篇再看能不能写出来吧吧
6.总结
本来之前是主要负责后端的，现在开始接触前端后不得不说前端的发展都超过自己的想象了。node.js还有vue之类的主流前端技术都完全没有
接触过，刚开始学起来完全是一脸懵逼，自己还停留在jquery，bootstrap之类的东西上。看了两三天天的教程才都是模糊的。这儿借鉴了很多
的博客，所以要是有博主发现和自己的很像还请见谅，因为我实在不能记住全部。
