搭建个ssm框架居然花费了我好长时间！特此记录！
需要准备的环境：
- idea 2017.1
- jdk1.8
- maven 3.3.9
请提前将idea与maven、jdk配置好，本次项目用的都是比较新的
注：配置完ide红线报错没关系！可以run！
步骤：
一、首先使用idea新建一个maven webapp项目
点击finish，第一次搭建可能会很慢，甚至可能需要vpn才能搭建成功
二、搭建目录结构
我这里列出的是搭建完了之后所有的目录和文件，诸位先把目录文件建起来，然后我在给出文件内容
这里的目录建好之后还需要设置一下，让idea识别目录作用，选择file-project structure
设置完成后ok
三、配置文件内容
pom.xml

然后新建个测试类，来测试mybatis

运行后结果应该是会在控制台输出id为1的用户名，没成功的话就找bug去吧...
继续新建个页面来测试springmvc和mybatis

新建完成后配置项目运行环境，点击run-edit configurations...
点击加号新建运行环境，选择tomcat server-local
选中新建好的服务器，右边选择deployment,点击加号-atifact...
选择第二项
然后在右边application context配置你的项目名
最后运行项目，在打开的页面中点击按钮测试，成功的话会在页面上显示id为1的用户信息
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持服务器之家。
