# SpringBoot-Vue 前后端分离开发
## 安装Vue.js
vue安装最新版本 npm install -g @vue/cli 或 yarn global add @vue/cli
Win R 输入vue -V 或者vue -version , 出现版本号即Vue可安装完成。
继续输入vue ui（vue要3.0以上版本才行） ,启动项目，会自动跳转http://localhost:8080/页面。
然后可创建项目vue项目进行开发啦。
### IEDA导入前端工程
### IDEA启动项目
打开Terminal 输入npm run serve即可。
### 编写代码
### 新建Book.vue
代码语言：javascript复制<template>
<div>
<table>
<tr>
<td>编号</td>
<td>图书名称</td>
<td>作者</td>
</tr>
<tr v-for="item in books">
<td>{{item.id}}</td>
<td>{{item.name}}</td>
<td>{{item.author}}</td>
</tr>
</table>
{{msg}}
</div>
</template>
<script>
export default {
name:"Book",
data(){
return{
msg:"Hello Vue",
books:[{
id: 1 ,
name: '千羽',
author: '千羽的编程之路'
},{
id: 2 ,
name: '千寻',
author: 'SpringBoot-Vue 前后端分离开发'
},{
id: 3 ,
name: '小明',
author: 'SpringBoot入门到精通'
}
]
}
},
created() {
const _this = this
axios.get('http://localhost:8181/book/findAll').then(function(resp){
_this.books = resp.data
})
}
}
</script><style scoped=""></style>配置路由
在terminal添加axios库：vue add axios
### 新建数据库
代码语言：javascript复制create databases library;
use databases;导入数据
创建SpringBootTest工程
添加lombok,Spring Web,SpringData Jpa,MySQL Driver
配置yml文件
代码语言：javascript复制spring:
datasource:
url: jdbc:mysql://localhost:3306/library?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
username: root
password: 123456
driver-class-name: com.mysql.cj.jdbc.Driver
jpa:
show-sql: true
properties:
hibernate:
format_sql: true
server:
port: 8181创建BookHandler
代码语言：javascript复制package com.southwind.springboottest.controller;
......
@RestController
@RequestMapping("/book")
public class BookHandler {
@Autowired
private BookReposity bookReposity;
@GetMapping("/findAll")
public List<Book> findAll(){
return bookReposity.findAll();
}
}创建实体类Book.java
代码语言：javascript复制package com.southwind.springboottest.entity;
import lombok.Data;
import javax.persistence.Entity;
import javax.persistence.Id;
@Entity //类名与表名绑定
@Data
public class Book { //编写实体类
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;
private String name;
private String author;
}
解决跨域问题CrosConfig.java
代码语言：javascript复制package com.southwind.springboottest.config;
@Configuration
public class CrosConfig implements WebMvcConfigurer {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedOrigins("*")
.allowedMethods("GET", "HEAD", "POST", "PUT", "DELETE", "OPTIONS")
.allowCredentials(true)
.maxAge(3600)
.allowedHeaders("*");
}
}创建BookReposity接口
代码语言：javascript复制package com.southwind.springboottest.reporesity;
public interface BookReposity extends JpaRepository<Book,Integer>{
}
debug测试
启动SpringboottestApplication
就可以实现前后端数据交互啦！
##实现技术:Spring Boot Vue,使⽤ Spring Boot 进⾏后端应⽤开发，使⽤ Vue 进⾏前端应⽤开发。
# Vue Element UI
> 先了解了一下Element(饿了么) UI，Element-Ul是饿了么前端团队推出的一款基于Vue.js 2.0 的桌面端UI框架。小编感觉它太强大了，主要你会查找和Ctrl C，会前端开发基本上问题不大。
## Vue 集成 Element UI
前提是要安装好Element插件，
### Element UI 后台管理系统主要的标签：
el-container：构建整个⻚⾯框架。
el-aside：构建左侧菜单。
el-menu：左侧菜单内容，常⽤属性：
:default-openeds：默认展开的菜单，通过菜单的 index 值来关联。
:default-active：默认选中的菜单，通过菜单的 index 值来关联。
el-submenu：可展开的菜单，常⽤属性：
index：菜单的下标，⽂本类型，不能是数值类型。
template：对应 el-submenu 的菜单名。
i：设置菜单图标，通过 class 属性实则。
el-icon-messae
el-icon-menu
el-icon-setting
el-menu-item：菜单的⼦节点，不可再展开，常⽤属性：
index：菜单的下标，⽂本类型，不能是数值类型。
## Vue router 来动态构建左侧菜单
- 导航1
- ⻚⾯1
- ⻚⾯2
- 导航2
- ⻚⾯3
- ⻚⾯4
## menu 与 router 的绑定
1. 标签添加 router 属性。
2. 在⻚⾯中添加 标签，它是⼀个容器，动态渲染你选择的 router。
3. 标签的 index 值就是要跳转的 router。
## Element UI 表单数据校验
> 定义 rules 对象，在 rules 对象中设置表单各个选项的校验规则
required: true, 是否为必填项
message: 'error', 提示信息
trigger: 'blur'，触发事件
> vuetest结构层次
