各位注意的nonce字段是response body里面的，并不是验签里面的wechatpayNonce字段，wechatpayNonce字段是回调中 request.getHeader("Wechatpay-Nonce")获取的;nonce字段是回调中@RequestBody(required = false) String data，data.nonce的字段

1）商户号： 161187795
2）商户名称：陕西车佰度
3）问题描述：GET 获取平台证书列表，需要对请求到的json密文进行解密，解密时报
解密时报javax.crypto.AEADBadTagException: Tag mismatch!
使用的是官网示例的AESUtil工具https://pay.weixin.qq.com/wiki/doc/apiv3/wechatpay/wechatpay4_2.shtml
根据官网https://pay.weixin.qq.com/wiki/doc/apiv3/wxpay/faq/chapter1_3.shtml给出的问题定位
1、使用了错误的API v3密钥，如使用了其他商户号的密钥，或者使用了APIv2的APIKey。
2、密文不正确。请检查提交解密的密文和收到的密文。注意报文中的密文经过了Base64编码。
3、解密时接口遗漏传入附加数据（associated_data）。
进行排查后都没有问题，但还是报javax.crypto.AEADBadTagException: Tag mismatch!异常
4）错误提示：
javax.crypto.AEADBadTagException: Tag mismatch!
