java - Getting a 'No thread-bound request found' error from spring in my web app

Question

I'm getting a 'No thread-bound request found' error in my web app and hoping to get some help. I'm trying to use struts2 + spring + hibernate, and use spring to manage the hibernate session factory, and inject hibernate sessions into my struts actions. I hope that made sense. When the app starts up, there are no errors, but when i make the first web request it bombs out with the 'No thread-bound request found' error. Here's my spring config:

<?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>

Here's my action:

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";
  }
}

My only lead is that if i remove the 'setHibernateSession' function above, i don't get the error because presumably spring doesn't bother creating a session if the action doesn't need one (lazy instantiation).

And here's the exception:

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.

Oh and the kicker is that my web.xml does have the necessary context listener, so the http request should be recognised by struts:

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

Answer 1

To use request scope without Spring MVC, you should declare RequestContextListener in web.xml (see 3.5.4.1. Initial web configuration):

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