HttpClient+json发送和接收参数——基于struts2或者ssh等框架

json操作需要的jar包：http://blog.csdn.net/bestcxx/article/details/49977333

发送方：

//模拟-查询支付情况-请求的方法test1()：
public void test1(){

  try {
  //创建连接
  HttpClient httpclient = new DefaultHttpClient();
  // 设置Cookie的兼容性       
  httpclient.getParams().setParameter(ClientPNames.COOKIE_POLICY, CookiePolicy.BROWSER_COMPATIBILITY);        
  httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
  httpclient.getParams().setParameter("http.protocol.content-charset","utf-8");  
  httpclient.getParams().setParameter(HTTP.CONTENT_ENCODING, "utf-8");  
  httpclient.getParams().setParameter(HTTP.CHARSET_PARAM, "utf-8");  
  httpclient.getParams().setParameter(HTTP.DEFAULT_PROTOCOL_CHARSET,"utf-8");
  // 15秒连接不上则失败       
  httpclient.getConnectionManager().closeIdleConnections(15, TimeUnit.SECONDS);  
 
  HttpPost httppost = new HttpPost("http://***/test2.do");                                                                        //这里路径设置为你自己的，比如127.0.0.1:8080/项目名/请求.do
 
  //创建JSON类型对象
  JSONObject json1=new JSONObject();
 
  //向JSON对象中放入json类型的数据
  json1.put("name", "李明1");
  json1.put("age", "10");
 
  HttpResponse response;
 
  StringEntity entity = new StringEntity(json1.toString(),"utf-8");//解决中文乱码问题    
  entity.setContentEncoding("UTF-8");    
            entity.setContentType("application/json");
  httppost.setEntity(entity);
response = httpclient.execute(httppost);

String result=EntityUtils.toString(response.getEntity(),"utf8");
result = StringUtils.isNotBlank(result) ? result : "noSuccess";
System.out.println(result);              //显示返回的json串

JSONObject jsonResult=JSONObject.fromObject(result);
System.out.println(jsonResult.get("name"));  //获取json中的参数
