spring mvc跨Controller传session

[pktmalaha]

1.版本3.2.9

2.我在/user/login中获得用户信息.把一个值对象保存到session中 ，可以/order下取不到session中值对象

/user/login的部分代码

		User u=userService.getUser(usermail, userpswd);
		if(u.getUid()>0){
			//S
			UserSessionBean usb=new UserSessionBean();
			usb.setUid(u.getUid());
			usb.setMail(u.getMail());
			usb.setToken(ApoUtil.getRandomString(6));
			model.addAttribute("aO", usb);
			
			Cookie c=new Cookie("JSESSIONID",s.getId());
			response.addCookie(c);
			s.setAttribute("usb", usb);
			return "redirect:/user/home";
		}
		return "user_login";

/order中取的代码

		int uid=0;
		try{
			UserSessionBean usb=(UserSessionBean)request.getSession().getAttribute("aO");
			System.out.println("--------------------session bean channel/mine:"+usb.toString()+"--------------------");
			uid=usb.getUid();
		}catch(NullPointerException e){
			return "redirect:/user/login";
		}

一走到/order控制器的方法只要执行这样的代码。就转到/user/控制器中,可这时/user/显示在线.UserSessionBean就是我说的值对象

applicationContext.xml中配置的这个值对象

<bean ...>
	<context:component-scan base-package="com.xxxx.service"></context:component-scan>
  	<context:annotation-config />
	<bean id="aO" class="com.xxxxx.servlet.UserSessionBean" scope="session"></bean>
</bean>

web.xml配置

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  <servlet>
    <servlet-name>a_client</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>/WEB-INF/a-config.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>a_client</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

分不多了。请见谅。搞了好久没整明白。

个人觉得看看你返回的JSESSIONID与浏览器提交的JESSIONID是否相同
