WireBox AOP supports the concept of self aspect bindings. This means that we can make things even simpler by letting the Aspect you build control what class and methods it will match against. This is great, one less thing to remember when developing the code. So let's start with the code first:

/**
* @classMatcher any
* @methodMatcher annotatedWith:transactional
*/
component name="TransactionAspect" implements="coldbox.system.aop.MethodInterceptor"{

    function init(){ return this; }

    function invokeMethod(required invocation) output=false{

        // Let's do the around advice now:
        transaction {
            // execute the method or other aspects in a transaction
            return arguments.invocation.proceed();
        }

    }
}

That's it! Our transaction aspect is done and it will also bind itself to ANY class and ANY method that has the transactional annotation. Then you just map it:

mapAspect("TransactionAspect").to("model.aspects.MyTransactionAspect");

We are done now, by mapping the aspect WireBox detects the two annotations classMatcher and methodMatcher and binds it for you. WOW, but where did you get that from? Well, the component has two annotations:

How cool is that! My aspect can determine the matching for me already.

Overiding Bindings

One thing to note about self binding aspects is that you can also override their matching by using the autoBind argument in the mapAspect() method call. So if you wanted to override the class and method matching on this aspect you would do this:

Create a classMatcher annotation on the component with the following DSL values:

Create a methodMatcher annotation on the component with the following DSL values:
