如何使用RestTemplate請求POST，使用用戶密碼授權

Question

有人可以告訴我如何使用RestTemplate來使用Authorization發佈HttpEntity對象。

public class FifthWay extends Thread { 

    public void run() { 
     String plainCreds = "anuj:khare"; 
     byte[] plainCredsBytes = plainCreds.getBytes(); 
     byte[] base64CredsBytes = Base64.encodeBase64(plainCredsBytes); 

     String base64Creds = new String(base64CredsBytes); 
     HttpHeaders headers = new HttpHeaders(); 
     headers.add("Authorization", "Basic " + base64Creds); 

     HttpEntity<String> postRequest = new HttpEntity<String>("FifthWay",headers); 

     RestTemplate rt = new RestTemplate(); 
     rt.getMessageConverters().add(new MappingJackson2HttpMessageConverter()); 
     rt.getMessageConverters().add(new StringHttpMessageConverter()); 

     String postUri = new String("http://169.194.48.182:8080/trade-capture-service/deals/persist"); 

     ResponseEntity<String> responseForPost = rt.exchange(postUri,HttpMethod.POST, postRequest, String.class); 
     String responseStringForPost = responseForPost.getBody(); 
     System.out.println(responseStringForPost); 
    } 

}

客戶端使用下面的代碼

@Controller 
@RequestMapping("/deals") 
public class RestController { 
... 
... 
@RequestMapping(value = "/check", method = RequestMethod.GET) 
    public @ResponseBody 
    String justACheck() { 
     System.out.println("It Works"); 
     return "It works"; 
    }

獲得這樣的錯誤：

Exception in thread "Thread-4" org.springframework.web.client.HttpClientErrorException: 415 Unsupported Media Type 

OR

Exception in thread "Thread-4" org.springframework.web.client.HttpClientErrorException: 400 Bad Request 

請幫

這裏是RestTemplate交換的例子：

RestTemplate restTemplate = new RestTemplate(); 
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter()); 
HttpHeaders requestHeaders = new HttpHeaders(); 
final HttpEntity entity = new HttpEntity(restCanvas, requestHeaders); 
return restTemplate.exchange(canvasAddUrl + value, HttpMethod.POST, entity, Integer.class); 

這裏canvasAddURL是你想用的上下文路徑調用URL。如果你想添加一個cookie，lemme知道，我已經刪除了該代碼，因爲它大部分時間沒有必要。這個返回值是ResponseEntity<Integer>。一探究竟。
