com.github.binarywang.wxpay.bean.entpay.EntPayRequest#storeMap中brandId空指针异常

[lzb-forever]

简要描述

com.github.binarywang.wxpay.bean.entpay.EntPayRequest#storeMap
brandId非必填但在storeMap中brandId.toString()是否会容易出现空指针异常

模块版本情况

• WxJava 模块名: 微信支付
• WxJava 版本号: v4.8.0

详细描述

在使用sdk企业付款到零钱时，为了方便重试或者为了记录日志，会在每次调用api后保存请求参数与响应参数，使用jackson以json字符串入库但现在因为brandId的问题无法转为json字符串，会报空指针异常
