好运哥电子面单签名工具类
由于好运哥官方并不直接提供对接sdk，签名文档写的也非常一般，开发人员对接比较麻烦，我根据文档自己编写了签名工具，有需要的可以直接使用，让开发更快一步。当然工具类中有些是不需要的可以自己删除下，我比较懒。下面是具体的类：
package com.x3.plug.waybill.utils;
import com.x3.base.core.exception.BusinessException;
import com.x3.base.core.util.JsonUtil;
import com.x3.plug.waybill.entity.PostAddr;
import com.x3.plug.waybill.request.WayBillCreateRequest;
import org.springframework.util.StringUtils;
import java.security.MessageDigest;
import java.util.*;
