在我的Web应用程序中从Spring收到“找不到线程绑定的请求”错误

我的网络应用程序出现“找不到线程绑定的请求”错误，希望获得帮助。我正在尝试使用struts2 + spring + hibernate，并使用spring管理hibernate会话工厂，并将hibernate会话注入我的struts动作中。我希望这是有道理的。当应用启动时，没有任何错误，但是当我发出第一个Web请求时，它以“未找到线程绑定的请求”错误轰炸。这是我的Spring配置：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd">
<beans>
  <bean id="hibernateSessionFactory" scope="singleton"
    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="configLocation" value="classpath:hibernate.cfg.xml" />
  </bean>
  <bean id="hibernateSession" factory-bean="hibernateSessionFactory"
    factory-method="openSession" destroy-method="close" scope="request" class="org.hibernate.Session" />
</beans>

这是我的动作：

package actions.events;
import org.hibernate.Session;
public class Listing {
  Session session;
  public void setHibernateSession(Session value) throws Exception
  {
    session = value;
  }
  public String execute() {
    return "success";
  }
}

我唯一的见解是，如果我删除了上面的“ setHibernateSession”函数，我不会收到错误消息，因为如果该动作不需要一个会话（惰性实例化），那么大概spring不会打扰创建一个会话。

这是一个例外：

Unable to instantiate Action, actions.events.Listing, defined for 'Listing' in namespace '/events'Error creating bean with name 'hibernateSession': Scope 'request' 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: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

哦，最重要的是，我的web.xml 确实具有必需的上下文侦听器，因此http请求应该由struts识别：

<?xml version="1.0" encoding="UTF-8"?>
<web-app ...
  ...
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  ...
</web-app>

回答：

要在没有Spring MVC的情况下使用请求范围，应RequestContextListener在web.xml中声明）：

<web-app>
  ...
  <listener>
    <listener-class>
        org.springframework.web.context.request.RequestContextListener
    </listener-class>
  </listener>
  ...
</web-app>
