Arquivo Discussoes de Programacao e Tecnologia Hi, All
I have this situation,
in my controller layer, they may throw exceptions, and I want to handle them in one place, for example, I want to log the exception details and forward the request to a jsp page to display some info to our clients.
is there any ways to satisfy my request?
pls be kindly reply this top in English or Chinese~thanks
you can create an interceptor to handle exceptions
Hi haiker. You are using the Vraptor3 or other version?
Do you need handle exceptions to display a more friendly error page for users or only for logging?
There are a issue at github (http://github.com/caelum/vraptor/issues/#issue/158) to create a pretty exception handler. See this page too: http://guj.com.br/posts/list/30/136307.java
So if you only need to logging the error and return to a generic page, you can use the error-page into your web.xml and create a simple interceptor to generate your log. See bellow.
@Intercepts
@RequestScoped
public class MyLoggingInterceptor implements Interceptor {
@Override
public boolean accepts(ResourceMethod method) {
return true; // intercept all requests
}
@Override
public void intercept(InterceptorStack stack, ResourceMethod method, Object resourceInstance)
throws InterceptionException {
try {
stack.next(method, resourceInstance);
} catch (Exception e) {
// my log code
// you can only print the log message or send by email, etc
}
}
}
Best regards
thank you all for your kindly response.
I like vraptor, it makes things easy~
