使用注解进行简化aop的配置
切点是run方法
Car.java
package com.lubby.bean;
import org.springframework.stereotype.Component;
@Component("car")
public class Car {
public void run(){
System.out.println("Car is running....");
}
}
DoSomething.java
package com.lubby.bean;
import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.AfterThrowing;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.stereotype.Component;
@Component
@Aspect
public class DoSomething {
@Pointcut("execution(* com.lubby.bean.Car.run(..))")
private void run() { }
@Before("run()")
public void prepare() {
System.out.println("checking the car");
}
@After("run()")
public void stop() {
System.out.println("stopping the car to stoping place....");
}
@AfterThrowing("run()")
public void fix() {
System.out.println("fixing thr car....");
}
