服务器的接口如果是springmvc，客户端除了用springmvc提供的RestTemplate请求，如下：
public class RestClient {private static Logger logger = Logger.getLogger(RestClient.class);@SuppressWarnings({ “rawtypes”, “unchecked” })public static Object post(String url, Map<String, Object> message) {Object result = null;try {RestTemplate rest = new RestTemplate();MultiValueMap<String, Object> param = new LinkedMultiValueMap();for(Entry<String, Object> entry : message.entrySet()) {param.add(entry.getKey(), entry.getValue());}result = rest.postForObject(url, param, String.class);} catch (Exception e) {logger.error(“发送消息发生异常”+e);}return result;}}
还可以用httpclient发送请求，，如下:
package import javaimport javaimport javaimport orgimport orgimport orgimport orgimport orgimport orgpublic class DownloadResourcesTest {public static void main(String[] args) {String url = “http://localhost:8080/xxx-web/xxx.mvc?apikey=1”;HttpClient client = new DefaultHttpClient(); HttpPost httpPost = new HttpPost(url); InputStream is = null;InputStreamReader isr = null;BufferedReader br = null;try {httpPost.addHeader(“city”, “010”);httpPost.addHeader(“version”, “2”);HttpEntity entity = new StringEntity(“<infos><info spid=\”188\” hash=\”4a0fd9704eb1432892cbc19742811b63\”>” +”</info><info spid=\”1601\” hash=\”4e7b8894b8bc4d4eac22dffd85f28a68\”></info></infos>”);httpPost.setEntity(entity);HttpResponse response = client.execute(httpPost);System.out.println(response.getStatusLine());is = response.getEntity().getContent();isr = new InputStreamReader(is, “UTF-8”);br = new BufferedReader(isr);StringBuffer buf = new StringBuffer();String line;while (null != (line = br.readLine())) {buf.append(line).append(“\n”);}System.out.println(buf.toString());} catch (Exception e) {e.printStackTrace();}}}
人生难免有挫折，但你是逃避不了的，一定要去面对它
