使用java发送HTTP请求

 public class Test {
     public static void main(String[] args) {
         BufferedReader in = null;
         String result = "";
         try {
             String path = "http://127.0.0.1:6666/webapp/servlet/workItemServlet?method=gotWorkItem&dataTime=05-01";
             URL realUrl = new URL(path);
             URLConnection connection = realUrl.openConnection();
             connection.setRequestProperty("accept", "*/*");
             connection.setRequestProperty("connection", "Keep-Alive");
             connection.setRequestProperty("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
             connection.connect();
             in = new BufferedReader(new InputStreamReader(connection.getInputStream(), "UTF-8"));
             String line;
             while ((line = in.readLine()) != null) {
                 result += line;
             }
             List<Object> list = JsonUtil.toObjectList(result, Object.class);
             for (Object obj : list) {
                 System.out.println(obj.toString());
             }
         } catch (Exception e) {
             System.out.println("12345 workItem find error");
         } finally {
             try {
                 if (in != null) {
                     in.close();
                 }
             } catch (Exception e2) {
                 e2.printStackTrace();
             }
         }
     }
