1、DefaultPointcutAdvisor 顾问

@Bean
public DefaultPointcutAdvisor getDefaultPointcutAdvisor() {
	DefaultPointcutAdvisor advisor = new DefaultPointcutAdvisor();

	//基于注解类的方法拦截
	advisor.setPointcut(new AnnotationMatchingPointcut(null, Log.class));
	advisor.setAdvice(new CustomMethodInterceptor());
	
//        NameMatchMethodPointcut pointcut = new NameMatchMethodPointcut();
//    	pointcut.addMethodName("show2");
	
//        JdkRegexpMethodPointcut pointcut = new JdkRegexpMethodPointcut();
//        pointcut.setPattern(".*show2.*");
	
//        AspectJExpressionPointcut pointcut = new AspectJExpressionPointcut();
//        pointcut.setExpression("execution(* com.seasy..*Impl.*(..))");
	
	return advisor;
}

 

2、RegexpMethodPointcutAdvisor 顾问

@Bean
public RegexpMethodPointcutAdvisor getRegexpMethodPointcutAdvisor() {
	//基于正则表达式的方法拦截
	RegexpMethodPointcutAdvisor advisor = new RegexpMethodPointcutAdvisor();
	advisor.setPattern(".*show2.*");
	advisor.setAdvice(new CustomMethodInterceptor());
	
	return advisor;
}

 

3、NameMatchMethodPointcutAdvisor 顾问

@Bean
public NameMatchMethodPointcutAdvisor getNameMatchMethodPointcutAdvisor() {
	//基于方法名的方法拦截
	NameMatchMethodPointcutAdvisor advisor = new NameMatchMethodPointcutAdvisor();
	advisor.addMethodName("show2");
	advisor.setAdvice(new CustomMethodInterceptor());
	return advisor;
}

 

4、AspectJExpressionPointcutAdvisor 顾问

@Bean
public AspectJExpressionPointcutAdvisor getAspectJExpressionPointcutAdvisor() {
	//基于切点语言的方法拦截
	AspectJExpressionPointcutAdvisor advisor = new AspectJExpressionPointcutAdvisor();
	advisor.setExpression("execution(* com.seasy..*Impl.*(..))");
	advisor.setAdvice(new CustomMethodInterceptor());
	return advisor;
}

 

5、ComposablePointcut 切入点

@Bean
public DefaultPointcutAdvisor getComposablePointcutAdvisor() {
	DefaultPointcutAdvisor advisor = new DefaultPointcutAdvisor();
	
	//组合切入点
	//union：并集, intersection：交集
	ComposablePointcut pointcut = new ComposablePointcut(ClassFilter.TRUE, new StaticMethodMatcher() {
		@Override
		public boolean matches(Method method, Class<?> targetClass) {
			return method.getName().equals("show");
		}
	});
	pointcut.union(new StaticMethodMatcher() {
		@Override
		public boolean matches(Method method, Class<?> targetClass) {
			return method.getName().equals("show3");
		}
	});
	
	advisor.setPointcut(pointcut);
	advisor.setAdvice(new CustomMethodInterceptor());
	
	return advisor;
}
