架构师之httpclient---------------httpurlconnection的post连接action

1.前言.
   如题.
2.代码.
   HttpURLConnection 连接servlet例子,servlet也可以是封装的action,能取到request就可以了.
  

    public static void main(String[] args) throws IOException {  
            String r = AnalysisXML.getXml(); //要传入的xml字符串  
            String path ="http://localhost:8080/axis/services/bxserver";  
            java.net.URL url = new java.net.URL(path);    
            // 打开连接  
            HttpURLConnection connection = (HttpURLConnection) url  
                    .openConnection();  
            // 设置是否向connection输出，因为这个是post请求，参数要放在  
            // http正文内，因此需要设为true  
            connection.setDoOutput(true);  
            connection.setDoInput(true);  
            connection.setRequestMethod("POST");  
            // Post 请求不能使用缓存  
            connection.setUseCaches(false);  
            connection.setInstanceFollowRedirects(true);  
            connection.setRequestProperty("Content-Type",  
                    "text/xml");  
            connection.connect();   
            DataOutputStream out = new DataOutputStream(connection  
                    .getOutputStream());  
            out.writeBytes(r);   
            out.flush();    
            out.close();  
            BufferedReader reader = new BufferedReader(new InputStreamReader(  
                    connection.getInputStream()));  
            String line;  
            System.out.println("=============================");  
            System.out.println("Contents of post request");  
            System.out.println("=============================");  
            while ((line = reader.readLine()) != null) {  
                System.out.println(line);  
            }  
            System.out.println("=============================");  
            System.out.println("Contents of post request ends");  
            System.out.println("=============================");  
            reader.close();  
            connection.disconnect();  
        }  

Servlet中获取流信息：

[java] view plaincopyprint?在CODE上查看代码片派生到我的代码片

    String resultXml = "";  
            boolean resultStr = true;  
            String XMLData = null;  
            StringBuffer tempStringBuffer = new StringBuffer();  
            String tempString = null;   
            BufferedReader reader = request.getReader();  
            while ((tempString = reader.readLine()) != null){  
                tempStringBuffer.append(tempString);  
            }   
            XMLData = tempStringBuffer.toString();
