所以，我正在开发一个 java 应用程序，它将使用 API (multipart/form-data 和 json) 发送它时，我收到错误 500: POST request for "https://xxx.xxxx.xx.xxx/xx/ xxxxx”导致 500（内部服务器错误）customresponseerror 说：无法提取响应：没有找到适合响应类型 [java.lang.String] 和内容类型 [text/html;charset=utf-8] 的 HttpMessageConverter
这是我的代码：
@Controller
public class ActionController {
private String interactions;
private HttpHeaders createHeaders( ){
return new HttpHeaders(){
{
String auth = "xxxx@xxxxx" + ":" + "xxxxxxxxx";
byte[] encodedAuth = Base64.encode(
auth.getBytes(Charset.forName("US-ASCII")) );
String authHeader = "Basic " + new String( encodedAuth );
set( "Authorization", authHeader );
}
};
}
@RequestMapping(value = "/createcontent", method = RequestMethod.GET)
@ResponseBody
public ResponseEntity<String> sendCreateContent() throws MalformedURLException, IOException, ParseException {
RestTemplate restTemplate = new RestTemplate();
HttpHeaders httpHeaders = createHeaders();
List<MediaType> acceptableMediaTypes = new ArrayList<MediaType>();
acceptableMediaTypes.add(MediaType.APPLICATION_JSON);
httpHeaders.setAccept(acceptableMediaTypes);
httpHeaders.setContentType(MediaType.MULTIPART_FORM_DATA);
MultiValueMap<String, Object> cnt = new LinkedMultiValueMap<String, Object>();
ContentDTO contentDTO = new ContentDTO();
contentDTO.setExternal_id("CNT1");
contentDTO.setTemplate_type_id(103);
contentDTO.setChannel_id("CHN1");
contentDTO.setTitle("Conteudo1");
contentDTO.setText("Conteudo teste 1");
RulesDTO rules = new RulesDTO();
SimpleDateFormat publish_date = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss-SSS");
java.util.Date pdate = publish_date.parse("2013-12-28 11:18:00-030");
java.sql.Timestamp pubdate = new java.sql.Timestamp(pdate.getTime());
rules.setPublish_date(pubdate);
SimpleDateFormat expiration_date = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss-SSS");
java.util.Date edate = expiration_date.parse("2014-12-28 11:18:00-030");
java.sql.Timestamp expdate = new java.sql.Timestamp(edate.getTime());
rules.setExpiration_date(expdate);
rules.setNotify_publish(true);
rules.setNotify_expiration(false);
rules.setHighlihted(true);
contentDTO.setRules(rules);
InteractionsDTO interactions = new InteractionsDTO();
interactions.setAllow_comment(true);
interactions.setAuto_download(false);
contentDTO.setInteractions(interactions);
cnt.add("content", "contentDTO");
cnt.add("file", "text.txt");
HttpEntity<MultiValueMap<String, ContentDTO>> request = new HttpEntity<MultiValueMap<String, ContentDTO>>(httpHeaders);
List<HttpMessageConverter<?>> messageConverters = new ArrayList<HttpMessageConverter<?>>();
FormHttpMessageConverter converter = new FormHttpMessageConverter();
messageConverters.add(converter);
CustomResponseErrorHandler errorHandler = new CustomResponseErrorHandler();
restTemplate.setMessageConverters(messageConverters);
restTemplate.setErrorHandler(errorHandler);
HttpEntity<String> response2 = restTemplate.exchange("https://xxx.xxxx.xx.xxx/xx/xxxx", HttpMethod.POST, request, String.class);
String response3 = null;
return null;
}
}
以防万一有人想查看我的 ContentDTO、InteractionsDTO 和 RulesDTO，它遵循这个结构（上图），并创建了“getter 和 setter”和“超级类的构造函数”。
结构：
content={
"external_id": 1000,
"template_type_id": 103,
"channel_id": 226,
"title": "Título do Conteúdo",
"text": "Descrição do Conteúdo",
"rules": {
"publish_date": "2012-07-20T11:18:00-03:00",
"expiration_date": "2012-08-25T11:18:00-03:00",
"notify_publish": true,
"notify_expiration": false,
"highlighted": true
},
"interactions": {
"allow_comment": true,
"auto_download": false
}
}
有人可以帮助我吗？
