1，客户端

public static void main(String\[\] args) \{  
Map<String, String> map = new HashMap<String, String>();  
        map.put("1", "bb");  
        map.put("2", "cc你好，接收到了没");  
        map.put("3", "dd");  
       JSONObject jsonObject = JSONObject.fromObject(map);  
        post(jsonObject, "url");  
\}

/\*\*  
\* post方式提交推送数据  
\* @param request  
\* @return  
\*/  
public static String post(JSONObject json,String url) \{  
HttpClient client = new DefaultHttpClient();  
HttpPost post = new HttpPost(url);  
post.addHeader("Content-type","application/json; charset=utf-8");  
post.setHeader("Accept", "application/json");  
//post.setEntity(new StringEntity(json.toString(), Charset.forName("UTF-8")));  
//post.addHeader("Authorization", "Basic YWRtaW46");  
String result = "";  
try \{  
StringEntity s = new StringEntity(json.toString(), "UTF-8");  
s.setContentEncoding(new BasicHeader(HTTP.CONTENT\_TYPE,"application/json"));  
post.setEntity(s);  
// 发送请求  
HttpResponse httpResponse = client.execute(post);  
// 获取响应输入流  
InputStream inStream = httpResponse.getEntity().getContent();  
BufferedReader reader = new BufferedReader(new InputStreamReader(inStream, "UTF-8"));  
StringBuilder strber = new StringBuilder();  
String line = null;  
while ((line = reader.readLine()) != null)  
strber.append(line + "\\n");  
inStream.close();  
result = strber.toString();  
System.out.println(result);  
if (httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC\_OK) \{  
System.out.println("请求服务器成功，做相应处理");  
\} else \{  
System.out.println("请求服务端失败");  
\}  
\} catch (Exception e) \{  
System.out.println("请求异常");  
throw new RuntimeException(e);  
\}  
return result;  
\}

2.接收数据

//test接收数据  
@RequestMapping("test")  
@ResponseBody  
public Map<String, String> test(HttpServletRequest request) throws IOException\{  
System.out.println("jinru=================");  
//后台接收  
request.setCharacterEncoding("UTF-8");  
BufferedReader br = new BufferedReader(new InputStreamReader(request.getInputStream(),"UTF-8"));  
String line = null;  
StringBuilder sb = new StringBuilder();  
while((line = br.readLine())!=null)\{  
   sb.append(line);  
\}  
// 将资料解码  
String reqBody = sb.toString();  
System.out.println("reqBody==="+reqBody);  
return null;  
\}
