How do you use Java 1.6 Annotation Processing to perform compile time weaving?
- by Steve
I have created an annotation, applied it to a DTO and written a Java 1.6 style annotationProcessor. I can see how to have the annotationProcessor write a new source file, which isn't what I want to do, I cannot see or find out how to have it modify the existing class (ideally just modify the byte code). The modification is actually fairly trivial, all I want the processor to do is to insert a new getter and setter where the name comes from the value of the annotation being processed.
My annotation processor looks like this;
@SupportedSourceVersion(SourceVersion.RELEASE_6)
@SupportedAnnotationTypes({ "com.kn.salog.annotation.AggregateField" })
public class SalogDTOAnnotationProcessor extends AbstractProcessor {
@Override
public boolean process(final Set<? extends TypeElement> annotations, final RoundEnvironment roundEnv) {
//do some stuff
}
}
