Stuck on AOP with AspectJ/Java

I've been looking forward to posting on the Big Moose Saloon, need help, probably something simple I'm missing...

I am working through Spring Into Action 3, on page 132 (4.5 of that unit) I'm working through an Aspect J example.

This is made up of 4 different file, CriticismEngine(Interface), CriticismEngineImpl(implmentation), JudgeAspect(AspectJ Aspect), Preformance(contains main method), and my Spring configuration, spring-idol.xml

here is the Error:

Now the four files:




and now my Spring configuration XML:

So, basically, when the bean with ID eddie preforms (that part of program works fine, just does a println of property values listed, criticismEngine is supposed to write criticism after the "preformance".

Let me know if anything else is needed, thanks!


public static final String mySignature = "yet to be written...";

looks like the problem lies here:

This is saying that there is a property on CriticismEngineImpl, called criticisms and you want to set a List<String> on it. So it expects the following:

You could actually leave it as a String[] if you wanted to and it should still work. Spring will figure it out. The reason it was failing is the setter name needs to match the property in the XML (minus the 'set' prefix)

Wow, I feel foolish for even asking a question with such a simple answer. The problem here was tunnel vision, the originally posted code was almost a direct copy from the book, this is the third error I have found in this book. I defined the property in the configuration file, obviously I need to inject those values, but for some reason I just didn't connect it.

Thank you very much,

I agree. Here's the link:
