建行的查询接口不如招行那么全面，建行没有提供按单订单号查询，而且如果你查询的日期没有一笔成功的订单会直接返回一个html告诉你没有信息，并且如果你跨天查询，订单很多很多，他也会返回一个html告诉你订单太多了，无法显示，所以鲁炬这里选择的是，每次只查一天的数据，如果是时间段就用程序分割成一天一天的去查，下面是选择用xml格式查询的解析核心代码。

private List queryOrderInfoByCcb(String orderDate) {

List list = new ArrayList();

String baseUrl = "https://ibsbjstar.ccb.com.cn/app/ccbMain?";

String MERCHANTID = this.getBankCono();

String BRANCHID = this.getBankBranchid();

String POSID = this.getBankPosId();

String ORDERDATE = orderDate;

String BEGORDERTIME = "00:00:00";

String ENDORDERTIME = "23:59:59";

String BEGORDERID = this.getBankPwd();

String ENDORDERID = "9999999999";

String QUPWD = "******";

String TXCODE = "410405";

String SEL_TYPE = "3";

String OPERATOR = "001";

String bankURL = "";

String result = "";

String param = "MERCHANTID=" + MERCHANTID + "&BRANCHID=" + BRANCHID + "&POSID=" + POSID + "&ORDERDATE=" + ORDERDATE

+ "&BEGORDERTIME=" + BEGORDERTIME + "&ENDORDERTIME=" + ENDORDERTIME + "&BEGORDERID=" + BEGORDERID

+ "&ENDORDERID=" + ENDORDERID + "&QUPWD=" + QUPWD + "&TXCODE=" + TXCODE + "&SEL_TYPE=" + SEL_TYPE

+ "&OPERATOR=" + OPERATOR + "&bankURL=" + bankURL + "&result=" + result + "&MAC=";

String tmp = "MERCHANTID=" + MERCHANTID + "&BRANCHID=" + BRANCHID + "&POSID=" + POSID + "&ORDERDATE=" + ORDERDATE

+ "&BEGORDERTIME=" + BEGORDERTIME + "&ENDORDERTIME=" + ENDORDERTIME + "&BEGORDERID=" + BEGORDERID

+ "&ENDORDERID=" + ENDORDERID + "&QUPWD=&TXCODE=" + TXCODE + "&SEL_TYPE=" + SEL_TYPE + "&OPERATOR=" + OPERATOR;

String strMD5 = ByteUtil.byteToChar(MD5Ccb.encode(tmp.getBytes()));

String xml = null;

try {

String url = baseUrl + param + strMD5;

log.debug("发送建行查询http请求:"+url);

xml = HttpClientUtil.getHtml(url);

} catch(IOException e) {

String msg = "建行对账文件获取HTTP访问失败,异常信息：" + e.getMessage();

log.error(msg);

throw new RuntimeException(msg);

}

if(xml.contains("您所在查询的IP地址有误")){

String msg = "查询日期:"+orderDate+"-建行对账系统提示信息:您所在查询的IP地址被限制访问，请联系建行将服务器地址加入到访问列表中后再进行对账操作。";

log.error(msg);

throw new RuntimeException(msg);

}

//根据查询条件未找到记录或记录太多

if(xml.contains("根据查询条件未找到记录或记录太多")){

String msg = "查询日期:"+orderDate+"-建行对账系统提示信息:根据查询条件未找到记录或记录太多,请修改查询日期。";

log.error(msg);

return list;

//throw new RuntimeException(msg);

}

xml = xml.trim();

log.debug("建行对账文件HTTP获取成功:xml长度:" + xml.length());

StringReader stringReader = new StringReader(xml);

Document doc = null;

try {

doc = new SAXReader().read(stringReader);

} catch(DocumentException e) {

String msg = "建行对账文件XML解析失败,异常信息：" + e.getMessage();

log.error(msg);

log.error("xml内容:"+xml);

throw new RuntimeException(msg);

}

Element element = doc.getRootElement();

List orders = element.elements();

for(Element el : orders) {

List orderContexts = el.elements();

double money = 0;//金额

String orderNum = null;//订单号

String orderStatus = null;//订单状态

for(Element orderEl : orderContexts) {

//log.debug(orderEl.getName() + " - " + orderEl.getText());

if("ORDERID".equals(orderEl.getName())) {

orderNum = orderEl.getText();

}

if("AMOUNT".equals(orderEl.getName())) {

money = Double.valueOf(orderEl.getText());

}

if("STATUS".equals(orderEl.getName()) && "成功".equals(orderEl.getText())) {

orderStatus = "0";

}

}

if(money != 0 && !StringUtils.isBlank(orderNum) && !StringUtils.isBlank(orderStatus)) {

OrderInfo orderInfo = new OrderInfo();

orderInfo.setTradeDate(orderDate);

orderInfo.setDealDate(orderDate);

orderInfo.setMoney(money);

orderInfo.setOrderNum(orderNum);

orderInfo.setOrderStatus(orderStatus);

list.add(orderInfo);

}

}

log.debug("解析建行对账文件成功：订单明细条数：" + list.size());

/*for(OrderInfo orderInfo : list) {

log.debug("解析建行对账文件成功：订单明细：" + orderInfo.toString());

}*/

log.debug("建行对账文件XML解析完毕！");

return list;

}

对HttpClient的封装，HttpClientUtil看这里
