java环境，按demo写的代码，比对了几遍字段没有发现错误，商户名称和结算银行账户开户名称也是一样的，能帮忙看看是哪里的问题吗
遇到相同的问题，请问解决了吗
merchant_name 是不是有符号？
bank_account_info/account_name 要用平台证书进行加密，你用的是不是商户证书加的密？
public String encrypt(String str) {X509Certificate wechatpayCertificate = verifier.getValidCertificate();try {return RsaCryptoUtil.encryptOAEP(str, wechatpayCertificate);} catch (IllegalBlockSizeException e) {}verifier是AutoUpdateCertificatesVerifier：verifier = new AutoUpdateCertificatesVerifier(new WechatPay2Credentials(mchId,new PrivateKeySigner(mchSerialNum, merPrivateKey)), apiv3Key.getBytes(DEFAULT_CHARSET));}StringEntity entity = new StringEntity(params);entity.setContentType("application/json;charset=utf-8");httpPost.setEntity(entity);httpPost.setHeader("Accept", "application/json");httpPost.setHeader("Wechatpay-Serial", wechatPaySerial);
