servlet读取xml格式的post数据

服务器端代码：

rundata.getModuleInfo().setLayoutTemplate(null); HttpServletRequest request = rundata.getRequest(); HttpServletResponse response = rundata.getResponse(); PrintWriter printWriter = null; ServletInputStream sis = null; String xmlData = null; try { printWriter = response.getWriter(); // 取HTTP请求流 sis = request.getInputStream(); // 取HTTP请求流长度 int size = request.getContentLength(); // 用于缓存每次读取的数据 byte[] buffer = new byte[size]; // 用于存放结果的数组 byte[] xmldataByte = new byte[size]; int count = 0; int rbyte = 0; // 循环读取 while (count < size) { // 每次实际读取长度存于rbyte中 rbyte = sis.read(buffer); for(int i=0;i<rbyte;i++) { xmldataByte[count + i] = buffer[i]; } count += rbyte; } xmlData = new String(xmldataByte, "UTF-8");

客户端代码：

HttpClient httpClient = new HttpClient(); String xmlData = getInput(); int xmlDataLength = xmlData.getBytes("UTF-8").length; PostMethod method = new PostMethod(url); method.setRequestBody(xmlData); method.setRequestHeader("Content-type", "text/xml; charset=UTF-8"); if (xmlDataLength < Integer.MAX_VALUE) { method.setRequestContentLength(xmlDataLength); } else { method.setRequestContentLength(EntityEnclosingMethod.CONTENT_LENGTH_CHUNKED); } try { int statusCode = httpClient.executeMethod(method); System.out.println("返回码： " + statusCode); if(statusCode != HttpStatus.SC_OK) { return; } System.out.println("输出:"); System.out.println(method.getResponseBodyAsString()); } catch (IOException e) { e.printStackTrace(); } finally { method.releaseConnection(); }

说明：

文件xml文件必须是utf-8形式，否则会有编码问题
