spring: @Pointcut给重复的注解/切点定义表达式

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");
	}
}

　　

2.Pointcut

org.aspectj.lang.annotation.Pointcut;

 package ch2.test;

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

 @Aspect
 public class Audience2 {

     //定义命名的切点
     @Pointcut("execution(** ch2.test.Performance.perform(..))")
     public void Performance(){}

     //表演开始之前:关闭手机
     @Before("Performance()")
     public void silenCellPhones()
     {
         System.out.println("silen cell phones");
     }

     //表演开始之前：入座
     @Before("Performance()")
     public void takingSeats()
     {
         System.out.println("take seats");
     }

     //表演开始之后：鼓掌
     @AfterReturning("Performance()")
     public void applause()
     {
         System.out.println("clap clap clap");
     }

     //表演结束之后：表演失败退票
     @AfterThrowing("Performance()")
     public void demandRefund()
     {
         System.out.println("demand refund");
     }

 }
