Playframework 1.2.7 interceptors - playframework-1.x

Question

There is a problem with PlayF 1.2.7 interceptors.
I have a controller AuthCtl with #Before annotation.
And another controller class AlarmCtl which uses #With(AuthCtl.class).
public class AuthCtl extends Controller {
public static final String KMK_AUTH_TOKEN = "KMK_AUTH_TOKEN";
public static final String KMK_USER_ID = "KMK_USER_ID";
#Before
static void checkAuthorization() throws KomekException {
if (request.cookies.containsKey(AuthCtl.KMK_AUTH_TOKEN) &&
request.cookies.containsKey(AuthCtl.KMK_USER_ID)) {
//Something
} else {
throw new UnauthorizedException();
}
}
#Catch
static void handleExceptions(Throwable t) {
response.status = ((KomekException)t).getErrorCode();
response.accessControl("*");
response.contentType = "application/json";
renderText(t.toString());
}
}
#With(AuthCtl.class)
public class AlarmCtl extends Controller {
//Something
}
So when I'm throwing exception in the checkAuthorization method my handleExceptions method doesn't intercept it. What's the problem?

Answer 1

You need to specify what type of exception(s) you want to catch.
So in your case it would need to be written like this:
#Catch(KomekException.class)
static void handleExceptions(Throwable t) {
response.status = ((KomekException)t).getErrorCode();
response.accessControl("*");
response.contentType = "application/json";
renderText(t.toString());
}
Or, for a general (kind of dirty) catch all, use the root Exception class:
#Catch(Exception.class)
static void handleExceptions(Throwable t) {
response.status = ((KomekException)t).getErrorCode();
response.accessControl("*");
response.contentType = "application/json";
renderText(t.toString());
}
