京东支付RSA公钥

public static String decrypt(String rsaPubKey, String strDesKey, String encrypt) {
    String reqBody = "";

    try {
        reqBody = ThreeDesUtil.decrypt4HexStr(RSAUtil.decryptBASE64(strDesKey), new String(Base64.decodeBase64(encrypt), "UTF-8"));
        String inputSign = JdPayXmlUtil.getXmlElm(reqBody, SIGN);
        reqBody = JdPayXmlUtil.addXmlHead(reqBody);
        reqBody = JdPayXmlUtil.fomatXmlStr(reqBody);
        String genSignStr = JdPayXmlUtil.delXmlElm(reqBody, SIGN);
        boolean verifyResult = VerifySignatureUtl.decryptMerchant(genSignStr, inputSign, rsaPubKey);
        if(!verifyResult) {
            logger.error("verify signature failed");
            throw new RuntimeException("verify signature failed");
        } else {
            return reqBody;
        }
    } catch (Exception var7) {
        logger.error("data decrypt failed");
        throw new RuntimeException("data decrypt failed");
    }
}

京东 解密方法第一个参数rsaPubKey， 是京东平台给对接方  生成好的公钥
