Configuring AspectJ aspects using Spring IoC with JavaConfig?

Question

According to Spring\'s Documentation Configuring AspectJ aspects using Spring IoC in order to configure an aspect for Spring IOC, the following has to be added to the xml co

Answer 1

Turns out that there is an org.aspectj.lang.Aspects class to provide for specifically this purpose. It appears that the aspectOf() method is added by the LTW which is why it works fine in XML configuration, but not at compile time.

To get around this limitation, org.aspectj.lang.Aspects provides a aspectOf() method:

@Bean
public com.xyz.profiler.Profiler profiler() {
    com.xyz.profiler.Profiler profiler = Aspects.aspectOf(com.xyz.profiler.Profiler.class);
    profiler.setProfilingStrategy(jamonProfilingStrategy()); // assuming you have a corresponding @Bean method for that bean
    return profiler;
}

Hope this helps someone else in the future.

Answer 2

Is there an equivalent way of writing this using JavaConfig?

Almost always.

@Bean
public com.xyz.profiler.Profiler profiler() {
    com.xyz.profiler.Profiler profiler = com.xyz.profiler.Profiler.aspectOf();
    profiler.setProfilingStrategy(jamonProfilingStrategy()); // assuming you have a corresponding @Bean method for that bean
    return profiler;
}

The factory-method is explained in the documentation in Instantiation with a static factory method.
