java URL实现调用其他系统发送报文并获取返回数据

模拟本系统通过Url方式发送报文到目标服务器，并获取返回数据：（实现类）

 import java.io.BufferedOutputStream;
 import java.io.BufferedReader;
 import java.io.InputStream;
 import java.io.InputStreamReader;
 import java.io.OutputStream;
 import java.io.OutputStreamWriter;
 import java.net.URL;
 import java.net.URLConnection;
 
 public class BlazeSao {
 
     public static void callBlaze(String url ,String data) throws Exception{
         URL u = new URL(url);
         System.out.println("建立链接....");
         //获取连接对象
         URLConnection uc = u.openConnection();
         uc.setDoOutput(true);
         //获取输出流对象
         OutputStream raw = uc.getOutputStream();
         OutputStream buffered = new BufferedOutputStream(raw);
         OutputStreamWriter out = new OutputStreamWriter(buffered, "UTF-8");
 
         System.out.println("发送报文:"+data);
         out.write(data);
 
         out.flush();
         System.out.println("关闭连接");
         out.close();
         //获取到返回数据的输入流
         InputStream is = uc.getInputStream();
         BufferedReader br = new BufferedReader(new InputStreamReader(is,"UTF-8"));
         String line = "";
         StringBuffer blzRspXml = new StringBuffer();
         System.out.println("获取返回数据:");
         while((line = br.readLine()) != null){
             //读取返回数据，分行读取
             System.out.println(line.trim());
             blzRspXml.append(line.trim());
         }
     }
 
     public static void main(String args[]){
 
         //目标服务器地址
         String url1 = "http://10.14.30.242:9080/RES/Rule";
         //发送的报文
         String data1 = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><CardRequest><SEQ_TIME_STAMP>2014325170152799504</SEQ_TIME_STAMP><TYPE>1</TYPE><v_101>-999998</v_101><v_102>0.002740</v_102><v_109>111.11</v_109></CardRequest>";
         try {
             BlazeSao.callBlaze(url1,data1);
         } catch (Exception e) {
             e.printStackTrace();
         }
     }
 
 }

输出日志：
