1、AOP基本搭建：

<dependency>
    <groupId>org.springframework</groupId>

    <version>4.3.8.RELEASE</version>
</dependency>  

@Configuration
@ComponentScan(value = "com.aop.test")
@EnableAspectJAutoProxy
public class ConfigAOP {
}

@Aspect
@Component
public class LogAspects {
    @Pointcut("execution( public int com.aop.test.MathCaculator.div(..))")
    public void pointcut(){
    }
    @Before("pointcut()")
    public void logstart(JoinPoint joinPoint){
        System.out.println("@Before      aop方法執行開始。。。。獲取方法名:"+joinPoint.getSignature().getName()+
        "獲取方法的引數列表:" +Arrays.asList(joinPoint.getArgs()));
    }
    @After("pointcut()")
    public void logEnd(){

    }
    @AfterReturning("pointcut()")
    public void logReturn(){
        System.out.println("@AfterReturning:   aop方法返回");
    }
    @AfterThrowing(value = "pointcut()",throwing = "exception")
    public void logException(Exception exception){
        System.out.println("@AfterThrowing    列印aop方法異常資訊：");
    }
}

@Component

    public int div(int a,int b) throws Exception {
        System.out.println("除法的方法主體");
        return a/b;
    }
}

public class Main {
    public static void main(String[] args) throws Exception {
        AnnotationConfigApplicationContext annotationConfigApplicationContext=new AnnotationConfigApplicationContext(ConfigAOP.class);
        System.out.println("容器初始化成功");

    }
}
