Log4j and AOP, how to get actual class name
提问by davioooh
I'm implementing a logger as an aspect using Spring AOP and Log4J, but I've noticed that the class name in log file is always the LoggerAspectclass name, so... is there a way to trace the actual class name in my log?
我正在使用 Spring AOP 和 Log4J 将记录器作为一个方面来实现，但我注意到日志文件中的LoggerAspect类名始终是类名，所以......有没有办法在我的日志中跟踪实际的类名?

@Around("execution(* com.mycontrollerpackage.*.*(..))")
public Object aroundWebMethodE(ProceedingJoinPoint pjp) throws Throwable {
String packageName = pjp.getSignature().getDeclaringTypeName();
String methodName = pjp.getSignature().getName();
long start = System.currentTimeMillis();
if(!pjp.getSignature().getName().equals("initBinder")) {
logger.info("Entering method [" + packageName + "." + methodName + "]");
}
Object output = pjp.proceed();
long elapsedTime = System.currentTimeMillis() - start;
if(!methodName.equals("initBinder")) {
logger.info("Exiting method [" + packageName + "." + methodName + "]; exec time (ms): " + elapsedTime);
}
return output;
}

this is easier:
这更容易：
pjp.getTarget().getClass()
回答by Nitul
Use: pjp.getTarget().getClass().getCanonicalName()
使用：pjp.getTarget().getClass().getCanonicalName()
Also, to add logs at class level of which method is being exexuted instead using logger of advice class, use class level logger within advice method, as below
此外，要在正在执行的方法的类级别添加日志而不是使用建议类的记录器，请在建议方法中使用类级别记录器，如下所示
Logger logger = Logger.getLogger(pjp.getTarget().getClass().getCanonicalName());
