Managing "hundreds" of classes with "hundreds" of methods with multiple annotations

[adenysenko]

Is there a way to manage "hundreds" of classes with "hundreds" of methods with multiple annotations?

[ryantenney]

What exactly do you mean by "manage"?

[adenysenko]

I mean configure "metrics" to collect in centralized way without having annotate at the method level.

[ryantenney]

There isn't, methods need to be annotated individually. If you're looking for a bulk approach I'd strongly consider using spring-aop. You would have to write a class which implements org.aopalliance.intercept.MethodInterceptor, but then you'd be able to instrument all your classes in a couple lines of XML:

    <bean id="metricsInterceptor" class="com.foo.MetricsMethodInterceptor" />
    <aop:config>
        <aop:advisor advice-ref="metricsInterceptor" pointcut="execution(public * com.foo.service..*(..))" />
    </aop:config>

It looks like the interceptor you are describing has similar functionality to your MeteredMethodInterceptor, TimedMethodInterceptor ....
Is it possible to reuse them?

[ryantenney]

Instances of the MeteredMethodInterceptor, etc in this project are all specific to one class and scan its methods for annotations. You'd do better to start from scratch.
