    public static <T, R>  String getFieldName(SerializationFunction<T, R> function) {
        Method method = null;
        try {
            method = function.getClass().getDeclaredMethod("writeReplace");
            method.setAccessible(true);
            SerializedLambda serializedLambda = (SerializedLambda) method.invoke(function);
            String methodName = serializedLambda.getImplMethodName();
            return methodName.substring(3);
        } catch (NoSuchMethodException | InvocationTargetException | IllegalAccessException e) {
            throw new RuntimeException(e);
        }
    }

@FunctionalInterface
public interface SerializationFunction<T, R> extends Function<T, R>, Serializable {
}

例如：String propertyName = xxx.getFieldName(类名::getXXX);
