RestTemplate访问Spring MVC restFul接口

在Spring MVC中，访问restful接口： 

RestTemplate restTemplate=new RestTemplate();  SimpleClientHttpRequestFactory requestFactory = new SimpleClientHttpRequestFactory();  //设置连接超时时间  requestFactory.setConnectTimeout(1000);  //设置读取超时时间  requestFactory.setReadTimeout(1000);  restTemplate.setRequestFactory(requestFactory);   JSONObject json=new JSONObject(param);  HttpHeaders httphead=new HttpHeaders();   httphead.setContentType(MediaType.parseMediaType("application/json; charset=UTF-8"));  httphead.add(HttpHeaders.ACCEPT,MediaType.APPLICATION_JSON.toString()); ;  HttpEntity<String> entity=new HttpEntity<String>(json.toString(),httphead);  String types= restTemplate.postForObject(url, entity,String.class);

设置头文件信息，以json格式传送
