spring+httpClient调用别人服务

首先，在spring的配置需要调用的url，例如：
[java]
<bean id="adManager" class="com.jd.hotel.manager.index.impl.AdManagerImpl">
<property name="adUrl" value="${hotel.ad.url}"/>
</bean>
在Manger调用的时候set注入进来

[java]
private List<GroupProduct> getData() throws Exception{
       Map<String, String> paraMap = new HashMap<String, String>();
       paraMap.put("action", "max_team_five_city_hotel_team_info");
       String result = httpClientUtilManager.executeHttpRequestByGetType(groupProductUrl, paraMap);
       List<GroupProduct> groupProducts = convertData(result);
       return groupProducts;
   }

executeHttpRequestByGetType方法：
[java]
/**
     * get方式提交
     *
     * @param url
     * @param keyValueMap
     * @return
     */
    public String executeHttpRequestByGetType(String url, Map<String, String> keyValueMap) {
        HttpClient client = new HttpClient();
        StringBuffer sb = new StringBuffer(url);
        PostMethod postMethod = null;
        try {
            //设置请求参数
            if (keyValueMap != null) {
                Iterator it = keyValueMap.entrySet().iterator();
                if (keyValueMap.size() > 0) {
                    sb.append("?");
                    while (it.hasNext()) {
                        Map.Entry<String, String> entry = (Map.Entry<String, String>) it.next();
                        sb.append(entry.getKey() + "=" + entry.getValue() + "&");
                    }
                    sb.deleteCharAt(sb.length()-1);
                }

            }
            postMethod = new PostMethod(sb.toString());
            log.debug("query uri ===============" + postMethod.getURI());
            postMethod.getParams().setParameter(HttpMethodParams.RETRY_HANDLER, new DefaultHttpMethodRetryHandler());
            postMethod.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "gbk");
            //todo:设置超时时间
            postMethod.getParams().setParameter(HttpMethodParams.SO_TIMEOUT, 200000);
            int statusCode = client.executeMethod(postMethod);
            if (statusCode != HttpStatus.SC_OK) {
                log.info("request '" + url + "' failed,the status is not 200,status:" + statusCode);
                return "";
            }
            String responseBody = postMethod.getResponseBodyAsString();
            return responseBody;
        } catch (Exception e) {
            log.error("发生异常！请检查网络和参数", e);
        } finally {
            if(postMethod!=null){
               postMethod.releaseConnection();
            }
        }
        return null;
    }
}

convertData方法：
[java]
private List<GroupProduct> convertData(String result) throws Exception{
       List<GroupProduct> groupProducts = new ArrayList<GroupProduct>();
       if(result==null || "".equals(result)){
           return groupProducts;
       }
       try {
           ArrayList<HashMap> hashMaps = (ArrayList<HashMap>) JSONUtil.deserialize(result);
           for (HashMap map : hashMaps) {
               GroupProduct groupProduct = new GroupProduct();
               groupProduct.setCityName(map.get("hotel_city").toString());
               groupProduct.setDesc(map.get("title").toString());
               groupProduct.setOldPrice(map.get("market_price").toString());
               groupProduct.setPrice(map.get("team_price").toString());
               groupProduct.setImgUrl(map.get("image").toString());
      &nbs
