常见Pointcout
1.NameMatchMethodPointcut

NameMatchMethodPointcut pointcut =new NameMatchMethodPointcut();
pointcut.setMappedName("matches");
//或多个方法
pointcut.setMappedNames(new String[]{"matches","isRuntime"});

2.JdkRegexpMethodPointcut、Perl5RegexpMethodPointcut

JdkRegexpMethodPointcut pointcut=new JdkRegexpMethodPointcut();
pointcut.setPattern(".*match.*");
//或者
pointcut.setPatterns(new String[](".*match.*",".*matches"});

3.AnnotationMatchingPointcut

@ClassLevelAnnotation
public class GenericTargetObject{
   @MethodLevelAnnotation
   public void method1(){....};
   public void method2(){....};
}

只匹配Class

AnnotationMatchingPointcut pointcut=new AnnotationMatchingPointcut(
   ClassLevelAnnotation.class);

或者用静态方法

AnnotationMatchingPointcut pointcut=AnnotationMatchingPointcut.forClassAnnotation(
   ClassLevelAnnotation.class);

只匹配Method

AnnotationMatchingPointcut pointcut=new AnnotationMatchingPointcut(
   MethodLevelAnnotation.class);

或者用静态方法

AnnotationMatchingPointcut pointcut=AnnotationMatchingPointcut.forMethodAnnotation(
   MethodLevelAnnotation.class);

匹配Class及Method

AnnotationMatchingPointcut pointcut=new AnnotationMatchingPointcut(
   ClassLevelAnnotation.class,MethodLevelAnnotation.class);
