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：

建立链接....

发送报文:<?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><v_110>111.11</v_110</CardRequest>

关闭连接
