HttpClientUtil 工具类 中 用 HttpPost 方式，表单提交参数 来 向 Jersey框架 发送请求 直接 上代码

//maven 添加========================

//post 提交方法

public static String getdoPost(String url, Map<String, String> mapdata) {
   CloseableHttpResponse response = null;
   CloseableHttpClient httpClient = HttpClients.createDefault();
   // 创建httppost
   HttpPost httpPost = new HttpPost(url);
   try {
      // 设置提交方式
      httpPost.addHeader("Content-type", "application/x-www-form-urlencoded");
      // 添加参数
      List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
      nameValuePairs.add(new BasicNameValuePair("data", mapdata.toString()));
      httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs,"UTF-8"));
　　　　//防止中文参数乱码设置
      InputStream contents = httpPost.getEntity().getContent();
      InputStreamReader inputStreamReader = new InputStreamReader(contents, "UTF-8");
      BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
      String readLine = bufferedReader.readLine();
      URLDecoder.decode(readLine, "UTF-8");
      // 执行http请求
      response = httpClient.execute(httpPost);
      // 获得http响应体
      HttpEntity entity = response.getEntity();
      if (entity != null) {
         // 响应的结果
         String content = EntityUtils.toString(entity, "UTF-8");
         return content;
      }
   } catch (Exception e) {
      e.printStackTrace();
   }
   return "获取数据错误";
}





//Jersey 接口 接收方法

@POST
@Path("/ceshi")
@Produces("application/json")
public Response saveWbzlAudit (@FormParam("data")JSONObject data) throws JSONException{

String userid=data.get("userid").toString();
String billno=data.get("sex").toString();

}
