RestEasy - UnsupportedMediaTypeException：无法使用内容类型

Question

我有一个应该接收混合MIME内容的弹簧MVC REST服务。如果我改变@Consumes注释，以便它使用@Consumes("multipart/form-data")而不是@Consumes("multipart/mixed")然后它

17:18:58,456 WARN [org.jboss.resteasy.core.SynchronousDispatcher] (http--127.0.0.1-8080-1) Failed executing POST services/createMime: org.jboss.resteasy.spi.UnsupportedMediaTypeException: Cannot consume content type

：控制器被定义为

@POST 
    @Path("/createMime") 
    @Consumes("multipart/mixed") 
    @ResponseStatus(HttpStatus.OK) 
    public String createMime(@Context ServletContext servletContext, MultipartInput input) throws MyRestException { 

     logger.info("Processing /createMime"); 

     return "TEST"; 
    } 

当我测试上面我碰到下面的错误。我需要做些什么来使它与多部分/混合工作？

以下是我如何使用客户端将内容发送到REST服务。

HttpClient httpclient = new DefaultHttpClient(); 
     HttpPost httppost = new HttpPost("http://localhost:8080/MyRestService/rest/services/createMime"); 

     Scanner scanner = 
      new Scanner(new File("header.xml")).useDelimiter("\\Z"); 
      String messageHeader = scanner.next(); 
      scanner.close(); 

     FileBody bin = new FileBody(new File("myImage.jpg")); 
     StringBody header = new StringBody(messageHeader.toString()); 

     MultipartEntity reqEntity = new MultipartEntity(); 
     reqEntity.addPart("header", header); 
     reqEntity.addPart("payload", bin); 
     httppost.setEntity(reqEntity); 

     HttpResponse response = httpclient.execute(httppost); 

我一直在挣扎与此相当长的一段时间，所以任何帮助将不胜感激。

感谢

尝试使用javax.ws.rs.core.MediaType字符串中，而不是把。它避免了可能的输入错误

Answer 2

您是否检查了请求的内容类型？我相信你的客户发送内容到REST服务是发布multipart/form-data请求。

要了解如何发送multipart/mixed request，您应该查看multipart内容类型的文档http://www.w3.org/Protocols/rfc1341/7_2_Multipart.html，第7.2.1节建议应指定和使用boundary。

基本上，你需要按照下面的要求做出multipart/mixed请求。

包括在报头中

Content-Type: multipart/mixed;boundary=gc0p4Jq0M2Yt08jU534c0p 

的边界中的每个请求的部分的应具有--boundary

--gc0p4Jq0M2Yt08jU534c0p 

最后部分应包括--boundary--

--gc0p4Jq0M2Yt08jU534c0p--
