廢話不多，直接上代碼！

 1     /**
 2      * 
 3      * @param httpUrl
 4      * @param reqInfo
 5      * @return
 6      */
 7     public static StringBuffer sendPost(String httpUrl, RequestInfoDTO reqInfo) {
 8         try {
 9             logger.info("請求地址 --->" + httpUrl);
10             PostMethod postMethod = new
 
 PostMethod(httpUrl);
11             HttpClient httpClient = new HttpClient(); 
12             String requestJson = com.bocins.springcloud.util.JsonUtils.obj2Json(reqInfo);
13             logger.info("請求參數轉json --->" + requestJson);
14             postMethod.setRequestEntity(new StringRequestEntity(requestJson, "text/xml", "GBK"));
 
15             httpClient.executeMethod(postMethod);
16             BufferedReader reader = null;
17             reader = new BufferedReader(new InputStreamReader(postMethod.getResponseBodyAsStream(),"UTF-8"));
18             String lines;
19             StringBuffer sb = new StringBuffer("");
20             while
 
((lines = reader.readLine()) != null){
21                 lines = new String(lines.getBytes());
22                 sb.append(lines); 
23             }
24             logger.info("服務調用返回結果 --->" + sb);
25             return sb;
26         }catch(Exception e){
27             logger.info("****************服務調用出錯****************",e);
28         }
29         return null;
30     }

HttpClient請求地址並攜帶參數
