虽然现在流行SpringBoot了，但是对于以前的SSM配置地狱的框架搭建整合做一个简单的Demo
首先创建新的项目，选择Maven管理我们的依赖 如图所示：
当然我是为了做列子，所以采用的中文，
然后选择自己的maven地址，这里稍微注意的是，Maven默认读取的是 .m2/setting.xml作为配置文件，
我改动了配置文件的相关下载和配置文件存储路径，所以我选用我自己的配置文件作为启动配置
然后等待下载，下载完之后，项目构建如下：
然后创建java 文件夹，作为我们存放代码的文件，并在下面创建出响应的 package 模块
最后就是这样的
——————————前期的基本准备工作到此为止，下面开始搭建环境————————————
先把最后的样子贴出来，可以先把结构搭起来，再填充内容：
1:优先配置 maven的 pom.xml 导入相关依赖

web.xml中指定的文件，我们按部就班的造出来

然后 applicationContext.xml 又依赖新的配置文件，逐一配置出来
jdbc.properties
jdbc.driver=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8jdbc.username=rootjdbc.password=root
logback.xml

运行服务器，看看效果
自动跳转到了默认的index.jsp
测试一下数据库，查询一点数据看看能否连通
发现自己都不太熟悉了，希望以后再也用不上！
