Spring AOP 进行统一日志处理

java代码：

import org.apache.log4j.LogManager;
import org.apache.log4j.Logger;
import org.aspectj.lang.ProceedingJoinPoint;

public class GenericLoggerBean {

	private static Logger logger = LogManager.getLogger(GenericLoggerBean.class);

	public Object invoke(ProceedingJoinPoint joinPoint) throws Throwable {
		System.out.println(joinPoint.getTarget().getClass());
		logger.warn("Beginning method : " +  joinPoint.getTarget().getClass() + "." + joinPoint.getSignature().getName()+ "()");
		long startTime = System.currentTimeMillis();
		try{
			Object result = joinPoint.proceed();
			return result;
		}catch(Exception e){
			logger.warn(  joinPoint.getTarget().getClass() + "." + joinPoint.getSignature().getName() + "() invoke error" );
			logger.warn("error info ["+e.getMessage()+"]");
		}finally{
			logger.warn("Ending method : " + joinPoint.getTarget().getClass() + "." + joinPoint.getSignature().getName() + "()");
			logger.warn("Method invocation time : " + (System.currentTimeMillis() - startTime) + " ms.");			
		}
		return null;
	}

}
