Resttemplate Webサービスのcomsumingのレスポンスタイプの問題

Question

次のREST Webサービスを記述しました。

ここでRestTemplateを使用してこのWebサービスを使用したいと思っています。しかし、restTemplate.exchange（？）の戻り値の型はどういうものかわかりません。

@RequestMapping(value = "/customercontact/transid/{brokerid}", method = RequestMethod.GET) 
     public ResponseEntity<HashMap<String, String>> getTransactionIdWithPublicKey(@PathVariable("brokerid") String brokerid){ 
     HashMap<String, String> transactionid = customerService.getTransactionid(brokerid); 
      if(transactionid != null) 
       return new ResponseEntity<HashMap<String, String>>(transactionid,HttpStatus.OK); 
      else 
       return new ResponseEntity<HashMap<String, String>>(HttpStatus.NOT_FOUND); 

     } 
public void doGet(HttpServletRequest request, 
          HttpServletResponse response) throws IOException 
     { 

RestTemplate restTemplate = new RestTemplate(); 
      HttpHeaders requestHeaders = new HttpHeaders(); 
      requestHeaders.add("SM_USER", "wbrokere"); 
      MultiValueMap<String, String> body = new LinkedMultiValueMap<String, String>(); 
      HttpEntity<?> httpEntity = new HttpEntity<Object>(body, requestHeaders); 
      ResponseEntity<String> responseobj = restTemplate.exchange("http://127.0.0.1:24000/webbroker/getusername", HttpMethod.GET, httpEntity,?); 
    } 

Answer 1

HashMap.class

ResponseEntity<HashMap> responseobj = `restTemplate.exchange("http://127.0.0.1:24000/webbroker/getusername", HttpMethod.GET, httpEntity,HashMap.class);` 
responseobj.getBody(); //To get the body of the response entity 

はのpom.xmlにJaksonの依存関係を追加するには、RESTサービスの中で使用したのと同じタイプ
