1、外部数据交换平台接口描述文档1．XML文件的导出和解析1，把数据包装成XML文件：示例：VoucherBrowseView.java建立输出流out=newPrintWriter(newFileWriter(dir+"/"+filename));输出到文件：象输出普通文本文件一样printxml(out,sep+sep+"");printxml(out,sep+sep+sep+""+(headvo.getDwbm()==null?"":headvo.getDwbm())+"");printxml(out,

2、sep+sep+sep+""+(headvo.getLbjc()==null?"":headvo.getLbjc())+"");printxml(out,sep+sep+sep+""+(headvo.getKjnd()==null?"":headvo.getKjnd())+"");printxml(out,sep+sep+sep+""+(headvo.getKjqj()==null?"":headvo.getKjqj())+"

3、cher_id>");printxml(out,sep+sep+sep+""+headvo.getFdjs()+"");printxml(out,sep+sep+sep+""+(headvo.getZdrq()==null?"":headvo.getZdrq())+"");2，发送文档到指定URL地址：a)获得连接publicURLConnectiongetConnection(Stringurl){//url=://webserver地址/servlet/nc.bs

4、.pfxx.manualload.ServletForXchange。URLConnectionconnection=null;try{//通过URL地址获得连接URLrealURL=newURL(url);URLConnectionconn=realURL.openConnection();//设置连接属性conn.setRequestProperty("Content-type","text/xml");connection=(URLConnection)conn;connection.setDoOutput(true);connection.setRequestM

5、ethod("POST");}catch(MalformedURLExceptionmex){mex.printStackTrace();}catch(ProtocolExceptionpex){pex.printStackTrace();}catch(IOExceptioniex){iex.printStackTrace();}returnconnection;}b)发送文档：publicvoidsendFile(Filefile){try{//获得一个输出流PrintWriterout=newPrintWriter(connection.getOutputStrea

6、m());//从文件获得输入BufferedReaderin1=newBufferedReader(newInputStreamReader(newFileInputStream(file),"gb2312"));//循环获得文件中的内容，并out发出Strings;while((s=in1.readLine())!=null){out.println(s);out.flush();}//关闭输出流out.close();}catch(Exceptionex){ex.printStackTrace();}}1，接收XML文档示例，从请求流中获得XML文档对象public

7、StreamToDoc(ServletRequestreq)throwsDTDCheckException{DOMParserparser=newDOMParser();try{//**获得InputStream对象，转换成InputSource*/InputStreamis=((InputStream)req.getInputStream());InputSourceinSrc=newInputSource(is);//**解析InputSource获得交换文档的Document对象*/parser.parse(inSrc);doc=p
