> {code:java}
> ClassPool pool = ClassPool.getDefault();
> CtClass superclass = pool.getCtClass(AbstractEntity.class.getName());
> CtClass cc = pool.makeClass("com.rapid.develop.entity.Ponit", superclass);
> ClassFile ccFile = cc.getClassFile();
> ConstPool constpool = ccFile.getConstPool();
> AnnotationsAttribute attr = new AnnotationsAttribute(constpool, AnnotationsAttribute.visibleTag);
> Annotation entityAnno = new Annotation("Entity", constpool);
> Annotation tableAnno = new Annotation("Table", constpool);
> tableAnno.addMemberValue("name", new StringMemberValue("test", ccFile.getConstPool()));
> attr.addAnnotation(entityAnno);
> attr.addAnnotation(tableAnno);
> ccFile.addAttribute(attr);
> Class clazz = cc.toClass();
> Object o = clazz.newInstance();
> assertTrue(o.getClass().getName().equals("com.rapid.develop.entity.Ponit"));
> // annotations length = zero
> java.lang.annotation.Annotation[] annotations = clazz.getDeclaredAnnotations();
> assertEquals(2, annotations.length); 
> {code}
> I used javassist to add annotation for class， I saw these annotations were added to class file.
> But I can't get them using java API clazz.getDeclaredAnnotations() and clazz.getAnnotations()
