当在Spring AOP中应用通知时，如何获得定义为切入点的方法的调用堆栈/调用者？

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.springframework.stereotype.Component;

@Aspect
@Component
public class MyAspect {

    @Before("execution(* com.example.MyClass.myMethod(..))")
    public void beforeAdvice(JoinPoint joinPoint) {
        String className = joinPoint.getSignature().getDeclaringType().getSimpleName();
        String methodName = joinPoint.getSignature().getName();
        System.out.println("调用者：" + className + "." + methodName);
    }
}
