How to create an interceptor for annotation @Controller

Question

I joined an existing project who use 2 mechanisms for the front-end with spring mvc:

A) controllers classes extends org.springframework.web.servlet.mvc.SimpleFormController
B) controllers classes uses annotation @Controller.

Now I found an interceptor:

@Aspect
public class RequestMonitor {

    @Autowired
    private RequestMonitorService requestMonitorService;

    @Before("execution(* org.springframework.web.servlet.mvc.Controller+.handleRequest(javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpServletResponse))"
            + "&& args(request,response)")
    public void storeUserAccess(HttpServletRequest request, HttpServletResponse response) {
        requestMonitorService.storeUserAccess(request);
    }
}

who catch all requests from org.springframework.web.servlet.mvc.Controller (mechanism A)

How can I adapt to intercept all other controllers with annotations "@Controller": org.springframework.stereotype.Controller (mechanism B)

You have the HandlerInterceptorAdapter class. You can extend it and make use of the methods in your subclass :

public boolean preHandle(HttpServletRequest request, 
        HttpServletResponse response, Object handler) throws Exception

public void postHandle(
        HttpServletRequest request, HttpServletResponse response, 
        Object handler, ModelAndView modelAndView)
        throws Exception

And you need to register your interceptor i.e:

<mvc:interceptors>
        <bean class="my.fully.qualified.package.RequestInterceptor" />
</mvc:interceptors>

We use Spring 2.5 and not 3 :( – BasicCoder Jul 02 '12 at 15:45 — BasicCoder, Jul 02 '12 at 15:45
