Using Spring AOP to profile application

1. Create java class:

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.aspectj.lang.ProceedingJoinPoint;

public class MyProfiler
{
  Log logger = LogFactory.getLog(getClass());
 
  public MyProfiler () {
    this.logger.info("Initialized");
  }
 
  public Object methodResponseTime(ProceedingJoinPoint call) throws Throwable
  {
    Long startime = Long.valueOf(System.currentTimeMillis());
    try { Long responseTime;
      return call.proceed();
    } finally {
      Long responseTime = Long.valueOf(System.currentTimeMillis() - startime.longValue());
      this.logger.info(String.valueOf(call.getSignature().toLongString()) + "::Response Time::" + responseTime);
    }
  }
}

 2. Spring context: create and configure spring to profile all methods in specified class

<beans xmlns="http://www.springframework.org/schema/beans"

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

       <bean id="schedulerProfiler" class="X.X.MyProfiler" />

       <aop:config>

              <aop:aspect ref=" MyProfiler ">

                           expression="execution(* com.X.business.myBusiness.*(..))" />
