项目整合

ssm各配置文件管理范围如图：

从上图可以看出，基于Maven的三个框架整合时，需要的配置文件包括：
（1）Maven的pom.xml文件—引入相关依赖；

（2）Web项目的web.xml文件-----配置全局的相关信息，如核心控制器，默认首页，
过滤器，spring框架的配置文件信息等

    
 	<context-param>context-param>
 	
    
	<listener>listener>
	
    
     <servlet>
        
       
        
     
          
    servlet>
    
	  
	 <servlet-mapping>servlet-mapping>
	 
    
	<welcome-file-list>welcome-file-list>

（3）Spring框架的applicationContext.xml文件----配置service层、bean层、mapper层、Mybatis框架的Session对象等中的相关类信息；

（4）SpringMVC框架的springmvc.xml文件----配置对controller层的类管理、对静态资
源的管理等；

（5）Mybatis的SQL局部映射mapper.xml文件----配置对某个表操作的SQL语句；

创建web项目

使用自带的archetype

配置tomcat
