调用webservice
准备条件:请求调用的方法、参数、请求的URL路径必须知道
private static String getSoapRequest(String areaCode,String content, String infoType, String reportDate) {StringBuilder sb = new StringBuilder();sb.append("<?xml version=\"1.0\" encoding=\"utf-8\"?>"+ "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" "+ "xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" "+ "xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">"+ "<soap:Body>"//请求调用的方法+"<pushDateInfo xmlns=\"http://shcholBestWebservice.ffti.com\">"+"<DateInfo>"//这种方式传的是一个对象，根据请求报文格式也可以直接传一个string参数+ "<areaCode>" + areaCode + "</areaCode>"+ "<content>" + content + "</content>"+ "<infoType>" + infoType + "</infoType>"+ "<reportDate>" + reportDate + "</reportDate>"+"</DateInfo>"+"</pushDateInfo>"+ "</soap:Body></soap:Envelope>");return sb.toString();}private static InputStream getSoapInputStream(String areaCode,String content, String infoType, String reportDate)throws Exception {try {String soap = getSoapRequest( areaCode, content,infoType,reportDate);if (soap == null) {return null;}//System.out.println(soap);//请求的URL路径URL url = new URL("URL地址");URLConnection conn = url.openConnection();conn.setUseCaches(false);conn.setDoInput(true);conn.setDoOutput(true);conn.setRequestProperty("Content-Length", Integer.toString(soap.length()));conn.setRequestProperty("Content-Type", "text/xml; charset=utf-8");conn.setRequestProperty("SOAPAction","");OutputStream os = conn.getOutputStream();OutputStreamWriter osw = new OutputStreamWriter(os, "utf-8");osw.write(soap);osw.flush();osw.close();InputStream is = conn.getInputStream();return is;} catch (Exception e) {e.printStackTrace();return null;}}
接下来要做的就是对获取到的输入流做一些操作，如把输入流进行包装读取其中的报文
BufferedReader br = new BufferedReader(new InputStreamReader(is));StringBuffer sb = new StringBuffer();String message = "";while((message=br.readLine())!=null){sb.append(message);}return sb.toString();
说明：如果响应报文是包含命名空间格式的，解析使用dom4j配合xpath的api进行。
