Spring AOP XML配置及註解配置

一.XML配置切面類

1.日誌切面類

//切面類註解配置加兩個註解
@Aspect
@Component
public class LoggerAspect {
    public Object log(ProceedingJoinPoint joinPoint) throws Throwable {
        System.out.println("start log:" + joinPoint.getSignature().getName());
        Object object = joinPoint.proceed();
        System.out.println("end log:" + joinPoint.getSignature().getName());
        return object;
    }
}

2.業務類

//業務類
@Component
public class ProductService {
    public void doSomeService(){
        System.out.println("doSomeService");
    }
}

3.spring.xml
