import org.springframework.aop.MethodBeforeAdvice;

public class BuyAdvice implements MethodBeforeAdvice {

	Logger log = Logger.getLogger(BuyAdvice.class.getName());

	SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss E");

	public void before(Method arg0, Object[] arg1, Object arg2)
			throws Throwable {

		log.info(df.format(new Date()) + "  方法:" + arg0.getName() + " 被调用"
				+ ",传递的参数列表是:" + Arrays.toString(arg1));
