Hello Cezary,
that’s actually a great idea. I tried to add a service advisor, but it doesn’t
seem to do what I want:
@Match("PersistentLocale")
public static void adviseNullForDefaultLanguage(MethodAdviceReceiver receiver) {
MethodAdvice advice = new MethodAdvice() {
public void advise(MethodInvocation invocation) {
invocation.proceed();
if (invocation.getReturnValue() != null &&
invocation.getReturnValue().equals("en")) {
invocation.setReturnValue(null);
}
}
};
for (Method m : receiver.getInterface().getMethods()) {
if (m.getName().equals("get"))
receiver.adviseMethod(m, advice);
}
}
The basic idea was that a method called "get" on the service called
"PersistentLocale" returns null if the return value from the implementation is
"en", but actually nothing happens.
Any ideas what I’m doing wrong?
Best,
Rafael
