使用JavaConfig的话,可以在配置类的类级别上通过使用EnableAspectJ-AutoProxy注解启用自动代理功能。
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 Audience {
//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");
}
}
