Why server complaining about aspectOf is missing?

I am currently trying to inject Spring bean in AspectJ like the code shown below, anyhow I the server (WAS Liberty Profile) keep complaining the method aspectOf is missing. May I know how could I solve this problem?

application-context.xml

<aop:aspectj-autoproxy/>
<import resource="/context-file-A.xml"/>

context-file-A.xml

<bean id="loggingAspect" class="com.huahsin.LoggingAspect" factory-method="aspectOf">

JAVA code

@Aspect
public class LoggingAspect {
   ...
}

AspectJ needs to weave both - your aspect class and the target class.

Weaving your aspect class

Weaving the target class

  • adds calls to those methods.

This is a common error when wiring up aspect classes. It means that your aspect class, in this case LoggingAspect has not been converted into an aspect which can be applied.

2 methods to weave your class into an aspect are using the AJDT Eclipse plugin or the Maven AspectJ compiler plugin.

There are 3 ways to weave aspects:

  • Compile-time weaving: compile either target source or aspect classes via dedicated aspectj compiler;
  • Post-compile weaving: inject aspect instructions to already compiled classes (Can be applied to JAR files)
  • Load-time weaving: inject aspect instructions to the byte code during class loading, i.e. load instrumented class instead of the 'raw' one;

Before an aspect class can be applied to a class it first need to be 'weaved' into an aspect.

An weaved aspect class will have these static methods added.

The problem is that your AspectJ weaving process isn't working. So you're calling the aspectOf method on an ordinary Java class and not an AspectJ class.

A simple way to test this:

  1. Weave with a tool like the Eclipse plugin AJDT
  2. Create a simple JUnit test with Spring.
  3. Finally make it work inside WAS.
