How to inject dependencies into HttpSessionListener, using Spring?

Question

How to inject dependencies into HttpSessionListener, using Spring and without calls, like context.getBean(\"foo-bar\") ?

Answer 1

You can declare your HttpSessionListener as a bean in Spring context, and register a delegation proxy as an actual listener in web.xml, something like this:

public class DelegationListener implements HttpSessionListener {
    public void sessionCreated(HttpSessionEvent se) {
        ApplicationContext context = 
            WebApplicationContextUtils.getWebApplicationContext(
                se.getSession().getServletContext()
            );

        HttpSessionListener target = 
            context.getBean("myListener", HttpSessionListener.class);
        target.sessionCreated(se);
    }

    ...
}
