2.请求对账参数实体类

public class WXPayCheckAccountEntity {

    String appid= Constants.WXZN_WXAPP_ID; //公众账号ID
    String mch_id=Constants.WXZN_WXMCH_ID;//商户号

3.对账入库方法

        //加上秘钥
        String stringSignTemp= MD5Utils.getMD5Upper(signString+"&key="+ Constants.WXZN_WX_KEY);//注：key为商户平台设置的密钥key

        entit=new WXPayCheckAccountEntity(nonce_str,yesterday,stringSignTemp);

        String result= HttpUtil.sendDataUTF8(url,entit.getXml());
        System.out.println(result);
