Intellij idea通过maven搭建ssm框架(实现获取数据库数据显示在页面中)

其实idea和eclipse搭建ssm框架基本上相同，但是还是有些许的区别

• 首选我们建立一个maven项目
  
  maven项目名称等信息，自己填写好就行

• 来看看我们的项目结构，你可以像我一样建立起文件夹和文件的结构
  
  结构很清晰，我们慢慢搭建我们的ssm项目

• 我们打开项目设置在web项里，点击右边加号，让它获取我们的web.xml位置
  
  现在我们来写上面建立的文件里面的代码

• pom.xml

1. 代码就这么多了，还有一个数据库我想看实体类和jdbc.properties应该可以直接弄好

2. 然后我们添加tomcat
   

最后我们运行看看效果吧

完美运行（这个是表字段没有删之前的）。

如果要写junit单元测试的话要加上

@RunWith(SpringJUnit4ClassRunner.class)//帮我们创建容器
//指定创建容器是使用那些配置文件
@ContextConfiguration(locations = {"classpath*:/spring/applicationContext-dao.xml","classpath*:/spring/applicationContext-service.xml"})

3. 项目源代码及sql文件
