目录
1 ?准备工作
2 ?创建maven项目
2.1?打开几个窗口
2.2 建项目
3 ?基本文件夹结构
4 ?我们的目标是填满配置
4.1 pom.xml
4.2 jdbc.properties
4.3 log4j.properties
4.4 mybatis.xml
4.5 springMVC.xml
4.6 applicationContext.xml
4.7 web.xml
5 ?正式写代码
5.1 数据库
5.2 Test.java
5.3 TestController?.java
5.4 TestService.java
5.5 TestServiceImpl.java
5.6 TestDao.java
5.7 testMapper.xml
5.8 index.jsp(本例中没那么必要)
5.9?testPage.jsp
6 ?效果
7 ?结语
本文参考?https://blog.csdn.net/xingyuncaojun/article/details/80743353?没多大改变，虽有明显的拾人牙慧之嫌，但毕竟此文目的仅是供个人日后好找。
额……就是安装好什么JDK啦…MySQL数据库啦…Eclipse啦…哦，Eclipse上顺便配好maven和Tomcat。
我本次搭的时候采用的是JDK8.0、MySQL5.5、Eclipse jee?2018、maven3.6.1、Tomcat7。
准备好了，打开eclipse开始干正事。
无脑跟我做步骤：
根据个人喜好吧，推荐这几个：
2.1.1Package Explorer：（菜单）Window-->Show View-->other...-->搜索框里打“package”，选Package Explorer-->Open；
2.1.2Project Explorer：操作参考2.1.1；
2.1.3Servers：操作参考2.1.1；
2.1.4Console：操作参考2.1.1；
2.1.5Debug：操作参考2.1.1；
2.1.1项目编写用，2.1.2一会儿消除错误用，2.1.3服务器用，2.1.4控制台，2.1.5打断点。
在刚打开的两个窗口任一个（推荐project explorer）上单击鼠标右键-->New-->Other...
-->Maven-->Maven Project-->Next
-->勾选一下创建一个简单项目-->Next
-->填写项目信息-->Finish
这时候，来事了
当然，在这我还换了个jre，有需要的可参考步骤：在项目名上单击右键-->Build Path-->Configure Build Path...-->Libraries-->选中不需要的jar包点Remove-->Add Library...-->JRE System Library...-->Next-->选中你需要的jre-->Finish-->Apply
基本上，maven项目可以了，先不急着加jar包，下边先怼个基本架子。
这个就不废话了，哦，换个窗口，下图所示。
