Spring Event and Scope request - spring

Question

I would like to use Spring Event to "speak" with my beans in my web application.
So, for example, my bean which fires event is like this:
#Controller
#Scope("request")
#KeepAlive
public class Controller extends InitializingBean, ApplicationEventPublisherAware {
private ApplicationEventPublisher applicationEventPublisher;
public void test() {
applicationEventPublisher.publishEvent(new TestEvent(this));
}
}
And my listener event is like this:
#Component
#Scope("request")
#KeepAlive
public class Module implements ApplicationListener<TestEvent> {
#Override
public void onApplicationEvent(TestEvent event) {
}
}
The most important point is these beans are scope request because they need to be initialized at every time the page is called.
But in startup, I get this message:
Caused by: 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.
Like if Spring try to instantiate my Module bean in startup and as the bean is scope request, it can't do this (the context request is not instantiate)
If I delete event management, everything works fine.
So, my question is:
Is it possible to have event listener is scope request ? And how to do this ?
Thanks

Answer 1

Try to inject a scoped proxy in a Singleton ApplicationListener to handle the TestEvent.
#Scope(proxyMode=ScopedProxyMode.TARGET_CLASS, value="request")
public class TestEventHandler {
public void onTestEvent(TestEvent event)
// ...
}
}
public class TestEventApplicationListener implements ApplicationListener<TestEvent> {
#Autowired
private TestEventHandler handler;
#Override
public void onApplicationEvent(TestEvent event) {
handler.onTestEvent(event);
}
}
