Signature sig = pjp.getSignature();MethodSignature msig = null;if (!(sig instanceof MethodSignature)) {    throw new IllegalArgumentException("该注解只能用于方法");}msig = (MethodSignature) sig;Object target = pjp.getTarget();Method currentMethod = target.getClass().getMethod(msig.getName(), msig.getParameterTypes());
