How to define order of method interceptors in Guice?

Question

Sometimes there\'s a need to know the order of method interceptors that intercept a method call in Guice. A simple example scenario would be to use guice-persist provided @Trans

Answer 1

Guice invokes the interceptors in the order in which they were registered. So if you define them something like this:

bindInterceptor(any(), annotatedWith(Retry.class), retryInterceptor);
bindInterceptor(any(), annotatedWith(Transactional.class), transactionalInterceptor);

or

bindInterceptor(any(), annotatedWith(Retry.class), retryInterceptor, transactionalInterceptor);

the retryInterceptor will be executed before the transactionalInterceptor.

Same applies if you have multiple modules - the interceptors from first module are executed before the interceptors of the seconds module and so on.
