我觉得最好还是不要上框架，从创建项目，pom文件，创建mvc模块，完成最基本的增删改查，这已经算是入门springboot了，如果你再想通过vue写一个前端页面，可以考虑使用若依框架。
下面分享一下springboot+vue完成增删改查的过程。
先了解什么是springboot？
Spring Boot 是由 Pivotal 团队提供的全新框架，其设计目的是用来简化新 Spring 应用的初始搭建以及开发过程。该框架使用了特定的方式来进行配置，从而使开发人员不再需要定义样板化的配置。用我的话来理解，就是 Spring Boot 其实不是什么新的框架，它默认配置了很多框架的使用方式，就像 Maven 整合了所有的 Jar 包，Spring Boot 整合了所有的框架。
- 简化spring应用开发的一个框架；
- spring技术栈的一个大整合；
- J2EE开发的一站式解决方案；
使用Spring Boot有什么好处
其实就是简单、快速、方便！
平时如果我们需要搭建一个Spring Web项目的时候需要怎么做呢？
配置web.xml，加载spring和springMVC
配置数据库连接、配置spring事务
配置加载配置文件的读取，开启注解
配置日志文件
...
配置完成之后部署Tomcat调试
...
现在非常流行微服务，如果我这个项目仅仅只是需要发送一个邮件，如果我的项目仅仅是生产一个积分；我都需要这样折腾一遍!
但是如果使用 Spring Boot 呢？
很简单，我仅仅只需要非常少的几个配置就可以迅速方便的搭建起来一套 Web 项目或者是构建一个微服务！
Java程序员简历上的第二个项目
第一个项目应该是SSM整合，第二个应该就是Spring Boot + Vue了。

3、前端讲师列表
<template>
<el-form label-width="120px">
<el-form-item label="讲师名称">
<el-input v-model="teacher.name"/>
</el-form-item>
<el-form-item label="讲师排序">
<el-input-number v-model="teacher.sort" controls-position="right" min="0"/>
</el-form-item>
<el-form-item label="讲师头衔">
<el-select v-model="teacher.level" clearable placeholder="请选择">
数据类型一定要和取出的json中的一致，否则没法回填
因此，这里value使用动态绑定的值，保证其数据类型是number
<el-option :value="1" label="高级讲师"/>
<el-option :value="2" label="首席讲师"/>
</el-select>
</el-form-item>
<el-form-item label="讲师资历">
<el-input v-model="teacher.career"/>
</el-form-item>
<el-form-item label="讲师简介">
<el-input v-model="teacher.intro" :rows="10" type="textarea"/>
</el-form-item>
<!-- 讲师头像：TODO -->
<!-- 讲师头像 -->
<el-form-item label="讲师头像">
<!-- 头衔缩略图 -->
<pan-thumb :image="teacher.avatar"/>
<!-- 文件上传按钮 -->
<el-button type="primary" icon="el-icon-upload" @click="imagecropperShow=true">更换头像
</el-button>
v-show：是否显示上传组件
:key：类似于id，如果一个页面多个图片上传控件，可以做区分
:url：后台上传的url地址
@close：关闭上传组件
@crop-upload-success：上传成功后的回调
<input type="file" name="file"/>
<image-cropper
