使用Spring AOP并在日志文件中获取相应的类名

Question

我将Spring AOP用于日志记录。一切都在工作，但在日志中，我只得到了方面类的名称。我希望打印出相应的类名。下面是代码片段。以下代码需要做哪些更改才能满足我的需求。

    logger.info("After executing method : " + joinPoint.getSignature().getName());
    logger.info("***************************************************************************");
}

@Before("execution(* com.app.c2pc..*.*(..))")
public void logBefore(JoinPoint joinPoint) {

    logger.info("***************************************************************************");
    logger.info("Before executing method : " + joinPoint.getSignature().getName());
}

@Around("execution(* com.app.c2pc..*.*(..)) && !execution(* com.app.c2pc.login.LoginController.*(..)) ")
public Object logAround(ProceedingJoinPoint pjp) throws Throwable {

    long start = System.currentTimeMillis();
    Object clazz = pjp.getTarget().getClass().getName();
    String methodName = pjp.getSignature().getName();
    logger.info("Entering Class " + clazz + " With Method Name " + methodName);
    Object[] obj = pjp.getArgs();
    int i = 0;
    try {
        for (Object o : obj) {
            logger.info(++i + " : Parameter Name :" + (null != o ? o.toString() : ""));
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    Object output = pjp.proceed(pjp.getArgs());

    logger.info("Excecution Completed for method : " + methodName + " in Class : " + clazz + " with result "
            + output);
    long elapsedTime = System.currentTimeMillis() - start;
    logger.info("Execution time for method : " + methodName + " in Class : " + clazz + " : " + elapsedTime
            + " milliseconds.");
    return output;
}

@AfterThrowing(pointcut = "execution(* com.app.c2pc..*.*(..))", throwing = "error")
public void logAfterThrowing(JoinPoint joinPoint, Throwable error) {

    logger.info("Exception thrown by method : " + joinPoint.getSignature().getName());
    logger.info("Exception name : " + error);
}

@AfterReturning(pointcut = "execution(* com.app.c2pc..*.*(..))", returning = "result")
public void logAfterReturning(JoinPoint joinPoint, Object result) {

    logger.info("Method : " + joinPoint.getSignature().getName() + " returned value is : " + result);
}

可以使用“joinpoint.getTarget().getClass().getName（）”获得完全限定的类名，如“com.abc.pqr.myClass”

您可以使用“joinpoint.getTarget().getClass().getSimpleName（）”只获取类名，比如“MyClass”。
