外汇牌价趋势波动图
实现本文程序的几个关键技术：
1、趋势波动图的数据源，来自于中国建设银行官方提供的实时外汇牌价，共有13个币种的现钞买入卖出价和现汇买入卖出价，每2分钟对外公布一次最新价格。
2、本程序的对外展示使用了highstock.js
3、远程向建行官网读取报文数据时，使用了java编写的jsoup解析器。
我们通过访问中国建设银行官网，在其“外汇行情”栏目可以看到如下的牌价信息页面：
我们通过查看页面javascript源代码，经过分析，可以找到如下代码
var shpjBody_HTML=""; var sqpjBody_HTML=""; var link='/cn/home/news/jshckpj.xml'; $.ajax({ type:"POST", url:link, async:true, dataType:"xml", success:function(ResponseText){ //更新时间插入 var AVL_DT = $($(ResponseText).find('AVL_DT').first()).text(); var TIMESTAMP = $($(ResponseText).find('TIMESTAMP').first()).text(); $(ResponseText).find('ReferencePriceSettlement').each(function () { //币别 var CM_CURR_COD = $(this).find('CM_CURR_COD').text(); if (CM_CURR_COD==1) CM_CURR_COD = $(this).find('SELL_OUT_CURR_TYPE').text(); //现汇买入汇率 var FXR_XCH_BUYIN = $(this).find('FXR_XCH_BUYIN').text(); //现汇卖出汇率 var FXR_XCH_SELLOUT = $(this).find('FXR_XCH_SELLOUT').text(); //现钞买入汇率 var FXR_CUR_BUYIN = $(this).find('FXR_CUR_BUYIN').text(); //现钞卖出汇率 var FXR_CUR_SELLOUT = $(this).find('FXR_CUR_SELLOUT').text(); //shpjBody_HTML += "<tr><td>"+CM_CURR_NAME+"</td><td>"+FXR_XCH_BUYIN+"</td><td>"+FXR_XCH_SELLOUT+"</td></tr>"; //sqpjBody_HTML += "<tr><td>"+CM_CURR_NAME+"</td><td>"+FXR_CUR_BUYIN+"5</td><td>"+FXR_CUR_SELLOUT+"</td></tr>"; getCMCURRName(CM_CURR_COD, FXR_XCH_BUYIN, FXR_XCH_SELLOUT, false); getCMCURRName(CM_CURR_COD, FXR_CUR_BUYIN, FXR_CUR_SELLOUT, true); });
按上述ajax调用的url找到http://forex.ccb.com/cn/home/news/jshckpj.xml 经过分析，后台主机每隔2分钟便更新一次该xml，其报文格式如下

各个节点含义如下
CM_CURR_COD 币种
FXR_XCH_BUYIN 现汇买入价
FXR_XCH_SELLOUT 现汇卖出价
FXR_CUR_BUYIN 现钞买入价
FXR_CUR_SELLOUT 现钞卖出价
综上，我们便有了实现实时汇率趋势波动图的数据源基础，我们通过jsoup来远程获取该报文并解析：
private void fxread(){ String actualUrl = null; actualUrl = "http://forex.ccb.com/cn/home/news/jshckpj.xml"; Document doc = null; try { doc = Jsoup.connect(actualUrl).get(); } catch (IOException e) { System.out.println("远程获取汇率牌价失败" + e); } String avl_dt = ""; String timestamp = ""; Elements AVL_DT = doc.getElementsByTag("AVL_DT"); Elements TIMESTAMP = doc.getElementsByTag("TIMESTAMP"); avl_dt = AVL_DT.first().html(); timestamp = TIMESTAMP.first().html(); Elements eles = doc.getElementsByTag("ReferencePriceSettlement"); Iterator ite = eles.iterator(); while(ite.hasNext()){ Element ele = (Element)ite.next(); String CM_CURR_COD = ele.getElementsByTag("CM_CURR_COD").first().html(); String FXR_XCH_BUYIN = ele.getElementsByTag("FXR_XCH_BUYIN").first().html(); String FXR_XCH_SELLOUT = ele.getElementsByTag("FXR_XCH_SELLOUT").first().html(); String FXR_CUR_BUYIN = ele.getElementsByTag("FXR_CUR_BUYIN").first().html(); String FXR_CUR_SELLOUT = ele.getElementsByTag("FXR_CUR_SELLOUT").first().html(); HashMap hm = new HashMap(); hm.put("AVL_DT", avl_dt); hm.put("TIMESTAMP", timestamp); hm.put("CM_CURR_COD", CM_CURR_COD); hm.put("FXR_XCH_BUYIN", FXR_XCH_BUYIN); hm.put("FXR_XCH_SELLOUT", FXR_XCH_SELLOUT); hm.put("FXR_CUR_BUYIN", FXR_CUR_BUYIN); hm.put("FXR_CUR_SELLOUT", FXR_CUR_SELLOUT); DBTools.insertfx(hm); //将牌价记录保存到数据库 } }
之后，我们将每天的牌价记录组装成json格式返回给前台的highstock.js控件做展示即可。

关于highstock的详细使用，有官方文档，这里不再叙述。唯一需要说明的是上述json格式中的时间为UTC时间的毫秒数，我们计算的时候在返回之前，要按照东八区的北京时间来显示，那么就必须加上8小时了。
javascript代码如下，这里使用了jquery的getJSON方法:
