spring: @Pointcut给重复的注解/切点定义表达式

Posted 2020-10-21 穆晟铭

代码如下：

package ch2.test;

import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.AfterThrowing;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Aspect;


@Aspect
public class Audience {

	
	//表演之前：观点手机
	@Before("execution(** ch2.test.Performance.perform(..))")
	public void silenceCellPhones()
	{
		System.out.println("silenCellPhones");
	}
	
	//表演之前：就座
	@Before("execution(** ch2.test.Performance.perform(..))")
	public void takingSeats()
	{
		System.out.println("take seats");
	}
	
	//表演之后：鼓掌
	@AfterReturning("excuttion(** ch2.test.Performance.perform(..))")
	public void applause()
	{
		System.out.println("clap clap clap !!!");
	}
	
	//表演失败：退票
	@AfterThrowing("execution(** ch2.test.Performance.perform(..))")
	public void demandRefund()
	{
		System.out.println("demanding a refund");
	}
}
