找不到適用於響應類型和內容類型的HttpMessageConverter

我試圖使用spring rest模板獲取ResponseEntity，如下所示。我得到下面的錯誤，找不到適用於響應類型和內容類型的HttpMessageConverter

Caused by: org.springframework.web.client.RestClientException: Could not extract response: no suitable HttpMessageConverter found for response type [interface org.springframework.security.oauth2.common.OAuth2AccessToken] and content type [application/json;charset=ISO-8859-1]

代碼：

ResourceOwnerPasswordResourceDetails resource = new ResourceOwnerPasswordResourceDetails(); 

     resource.setAccessTokenUri("https://.../oauth2/token"); 
     resource.setUsername("u"); 
     resource.setPassword("p"); 
     resource.setClientSecret(".....s"); 
     resource.setClientId("....i"); 
     resource.setGrantType("password"); 
     List<String> scopes = new ArrayList<String>(2); 
     scopes.add("write"); 
     scopes.add("read"); 
     resource.setScope(scopes); 
     OAuth2RestTemplate oAuthRestTemplate = new OAuth2RestTemplate(resource); 

    try{ 
     SSLUtil.turnOffSslChecking(); 
     ResponseEntity<String> result = oAuthRestTemplate.getForEntity("https:......." + "/api/version", String.class); 
     System.out.println(result); 
      } catch (RestClientException e) {   
      e.printStackTrace(); 
     }

我試着設置介質類型爲application/JSON作爲this post.But還是同樣的錯誤。

完全跟蹤：

您需要添加MappingJackson2HttpMessageConverter並添加內容類型爲application/json的頭。見here

我使用spring3。試過這個..'List >轉換器= oAuthRestTemplate.getMessageConverters（）; （HttpMessageConverter 轉換器：轉換器）if（轉換器instanceof MappingJackson2HttpMessageConverter）{...} ..'但是不能工作。春天3有沒有關於獲取resttemplate的鏈接？ – NaaN
