spring-session-redis共享的配置，为了复制方便特意做到这里。

一、 maven web项目的依赖

pom.xml中添加properties


    		
             
     
      UTF-8
             
     
      UTF-8
             
             
     
      UTF-8
             
     		
     
      4.3.10.RELEASE

pom.xml添加web项目和spring的依赖

      spring-expression
     			
     
      ${spring.version}
     		
    					
    		
    			
     
      org.springframework
     			
     
      spring-context-support
     			
     
      ${spring.version}

      org.springframework
     			
     
      spring-jdbc
     			
     
      ${spring.version}
     		
    		
    			
     
      org.springframework
     			
     
      spring-tx

      ${spring.version}
     		
    		
    		
    			
     
      org.springframework

      ${spring.version}
     		
    		
    		
    			
     
      org.springframework
     			
     
      spring-test
     			
     
      ${spring.version}

pom.xml添加spring-session-redis的依赖


    		
    			
     
      org.springframework.session
     			
     
      spring-session-data-redis
     			
     
      1.3.1.RELEASE

二、修改web.xml


    
    	
     		
      
       index.jsp
      		
      
       index.html
      	
     	
     		
      
       contextConfigLocation
      		
      
       classpath:applicationContext.xml
      	
     	
     		
      
       log4jConfigLocation
      		
      
       classpath:log4j.properties
      	
     	
     		
      
       org.springframework.web.util.Log4jConfigListener
      	
     	
     		
      
       org.springframework.web.context.ContextLoaderListener
      	
     	
     	  
      
       org.springframework.web.context.request.RequestContextListener
      	
     		
     		
      
       springSessionRepositoryFilter
      		
      
       org.springframework.web.filter.DelegatingFilterProxy
      	
     	
     		
      
       springSessionRepositoryFilter
      		
      
       /*
      	
     		
     		
      
       springmvc
      		
      
       org.springframework.web.servlet.DispatcherServlet
      		
      			
       
        contextConfigLocation
       			
       
        classpath:springmvc-servlet.xml
       		
      		
      
       1
      	
     	
     		
      
       springmvc
      		
      
       *.do
      	
     		
     		
      
       2

在web.xml中添加了spring的配置，spring-mvc的配置，已经ContLoaderListener和RequestContextListener的监听。

附带提下ContextLoaderListener与RequestContextListener的区别

ContextLoaderListener extends ContextLoader implements ServletContextListener

RequestContextListener implements ServletRequestListener

ServletContextListener extends EventListener。

ServletContextListener只负责监听Web容器的启动和关闭的事件。

ContextLoaderListener(或ContextLoaderServlet)将Web容器与spring容器进行整合。


        
     
      org.springframework.web.context.ContextLoaderListener


      
     
      contextConfigLocation
       
     
      classpath:applicationContext.xml

如果没有显式声明，则 系统默认 在WEB-INF/applicationContext.xml，多个文件可以使用逗号分开。

ServletRequestListener extends EventListener。

ServletRequestListener监听HTTP请求事件，Web服务器接收的每次请求都会通知该监听器。

RequestContextListener将Spring容器与Web容器结合的更加密切。这是可选配置，并且后者与scope=”request”搭配使用。


      
     
      org.springframework.web.context.request.RequestContextListener

三、配置下applicationContext.xml和springmvc-servlet.xml

applicationContext.xml配置

springmvc-serlvet.xml配置

log4j的配置就不贴了。

四、测试对应的controller和jsp页面

<%@ page language="java" contentType="text/html; charset=UTF-8"	pageEncoding="UTF-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%>
    
    
    
    
    
    login.jsp

sessioninfo.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"	pageEncoding="UTF-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%>
    
    
    
    
    
    sessioninfo.jsp	<%String s = session.getId(); //获取session ID号  %>	<%=s %>		<%String username = (String)session.getAttribute("username"); //获取session ID号  %>	
	<%=username %>

TestController

package com.imddy.tsession.controller;import javax.servlet.http.HttpServletRequest;import org.apache.commons.logging.Log;import org.apache.commons.logging.LogFactory;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic class TestController {		private static Log log = LogFactory.getLog(TestController.class);		@RequestMapping("/loginGet")    public String loginGet(){		log.info("do loginGet ...");        return "/login";    }		@RequestMapping("/loginPost")    public String loginPost(HttpServletRequest request){		log.info("do loginPost ...");		String username = request.getParameter("username");		request.getSession().setAttribute("username", username);        return "redirect:/sessioninfo.do";    }		@RequestMapping("/sessioninfo")    public String sessioninfo(){		return "/sessioninfo";	}	}

测试到2个不通的tomcat中一个端口是8080,另一个端口是8090，测试结果如下图：
