Java Spring MVC处理会话已过期

我正在使用JBossEAP6.2、JavaEE6和SpringMVC4.0.2。 当会话过期时，我想执行页面重定向

我开发了一个Spring拦截器

@Component
public class SessionExpiredInterceptor extends HandlerInterceptorAdapter {


    static final Logger logger = Logger.getLogger(SessionExpiredInterceptor.class);
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
     final HttpSession session = request.getSession(false);
         if ( session == null || session.isNew() ) {
             ConfigurationProperties confProp = ConfigurationProperties.getInstance();
             logger.info("Sessione scaduta, redirect home page");
             request.getSession(true);
             response.sendRedirect(request.getContextPath() + "/" + 
                     confProp.getInstance().getProperty("session.expired.redirect"));
         } 
        return true;

    }
}

但我有以下的误解：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scopedTarget.navigator': Scope 'session' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton; nested exception is java.lang.IllegalStateException: JBWEB000043: Cannot create a session after the response has been committed

以下是

spring.xml

<mvc:interceptor>
    <mvc:mapping path="/**"/>
    <mvc:exclude-mapping path="/static/**" />
    <mvc:exclude-mapping path="/index.jsp" />
    <mvc:exclude-mapping path="/logout" />
    <mvc:exclude-mapping path="/ajax-logout" />
    <bean class="it.lispa.sire.finanziamentionline.web.mvc.SessionExpiredInterceptor" />
</mvc:interceptor> 


<mvc:interceptor>
    <mvc:mapping path="/home"/>
    <mvc:exclude-mapping path="/static/**" />
    <mvc:exclude-mapping path="/logout" />
    <mvc:exclude-mapping path="/ajax-logout" />
    <bean class="it.lispa.sire.finanziamentionline.web.mvc.UserSessionInterceptor"/>
</mvc:interceptor> 

你能帮我吗？

谢谢。

这里发生的是

SessionExpiredInterceptor

在

UserSessionInterceptor

之前动作。如果它检测到会话是新的，它将执行重定向

response.sendRedirect(request.getContextPath() + "/" + 
    confProp.getInstance().getProperty("session.expired.redirect"));

一旦你做了一个重定向，你基本上已经声明你已经完成了对请求的处理，并且已经发送了一个响应（301状态代码）。但是，在您的代码中，您将从

preHandle

返回

true

，这向

DispatcherServlet

指示它应该继续处理请求，执行其他拦截器，并最终到达

@控制器

你不会想要这个的。在
if
块中，在
sendRedirect
之后返回
false
，您能告诉我们您的
navigator
bean声明的位置和注入的位置吗？@SotiriosDelimanolis它被注入到某个控制器和其他Spring中Inspector@SotiriosDelimanolis我已将其插入问题中。感谢
预处理
在您问题的开头是在
会话ExpiredInterceptor
？@SotiriosDelimanolis是
response.sendRedirect(request.getContextPath() + "/" + 
    confProp.getInstance().getProperty("session.expired.redirect"));
