我有一个Spring MVC REST服务,应该接收混合的mime内容.控制器定义为
@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";
}
当我测试上面我得到以下错误：
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

如果我更改@Consumes注释以便它使用@Consumes(“multipart / form-data”)而不是@Consumes(“multipart / mixed”),那么它可以工作.我需要做什么才能让它与multipart / mixed一起使用？
以下是我使用客户端将内容发送到REST服务的方式.
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);
我一直在努力解决这个问题,所以任何帮助都将不胜感激.
谢谢
最佳答案
您是否检查了请求的内容类型？我相信您将客户端发送到REST服务的客户端是发布multipart / form-data请求.
要了解如何发送多部分/混合请求,您应该在http://www.w3.org/Protocols/rfc1341/7_2_Multipart.html查看多部分内容类型的文档,第7.2.1节建议应该指定和使用边界.
基本上,您需要按照以下要点进行多部分/混合请求.
在标题中包含边界
Content-Type: multipart/mixed;boundary=gc0p4Jq0M2Yt08jU534c0p
请求中的每个部分都应该有–boundary
--gc0p4Jq0M2Yt08jU534c0p
最后一部分应包括 – 边界 –
--gc0p4Jq0M2Yt08jU534c0p--
