Spring AOP Log4j

Spring-aop.xml – I am AOPing all packages using the pointcut.

Import this XML into your main spring xml

Next is the source for the performance logging advice

package com.test.common;

import java.lang.reflect.Method;

import org.springframework.aop.AfterReturningAdvice;
import org.springframework.aop.MethodBeforeAdvice;
import org.apache.log4j.Logger;

public class PerformanceLoggingAdvice implements MethodBeforeAdvice, AfterReturningAdvice {
    /** Time in milliseconds */
 long startTime = 0;

 /** Time in milliseconds */
 long finishTime = 0;

 protected static final Logger loggerObj =Logger.getLogger(PerformanceLoggingAdvice.class);
 
    public PerformanceLoggingAdvice() {
    }

    @Override
    public void afterReturning(Object returnValue,
  Method method, Object[] args, Object target) throws Throwable {
 finishTime = System.currentTimeMillis();
 double totalDuration = finishTime - startTime;
 loggerObj.info("Finished executing method " + method.getName()
  + " on object " + target.getClass().getName() + " in "
  + totalDuration / 1000 + " seconds.");
    }

    @Override
    public void before(Method method, Object[] args,
  Object target) throws Throwable {
 startTime = System.currentTimeMillis();
 loggerObj.info("Executing method " + method.getName()
  + " on object " + target.getClass().getName());
    }

}
