本文介绍如何在Spring框架下，通过AOP技术实现方法级别的性能统计，包括统计方法执行时间，并记录方法名、类名及运行时长。

<aop:aspectj-autoproxy proxy-target-class="true" />


<bean id="_sar_advisor_auto_proxy_creator"
class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator">
<property name="advisorBeanNamePrefix" value="_sar_" />
<property name="usePrefix" value="true" />
<property name="proxyTargetClass" value="true" />

</bean>

@Component
@Aspect
public class AccessTimeStatisticAdvice {

protected Log logger = org.apache.commons.logging.LogFactory.getLog(getClass());

@Around("within(@org.springframework.stereotype.Controller *)")
public Object doBasicProfiling(ProceedingJoinPoint pjp) throws Throwable {
logger.info("-------------------------------进入统计时间------------------------");
String className =pjp.getTarget().getClass().getName();
String methodName = pjp.getSignature().getName();
long startTime = System.currentTimeMillis();
Object object = pjp.proceed();// 执行该方法
long endTime = System.currentTimeMillis();
long duration = endTime - startTime;

logger.info("startTime:"+new Date().toLocaleString()+" className:"+className+" methodName:"+methodName+" runTime:"+duration);
logger.info("-------------------------------退出统计时间---------------------------");
return object;
}

}

Object[] args = pjp.getArgs();
Class[] argsClazz = new Class[args.length];
//Controller中所有方法的参数，前两个分别为：Request,Response
argsClazz[0] = HttpServletRequest.class;
argsClazz[1] = HttpServletResponse.class;
//第三个为保存中的上传的Model
if (args.length == 3) {
argsClazz[2] = args[2].getClass();
}
