HTTP Status 415 - Unsupported Media Type

server 代码：

@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(
@FormDataParam("file") InputStream uploadedInputStream,
@FormDataParam("file") FormDataContentDisposition fileDetail) {
System.out.println("uploadFile start");


String uploadedFileLocation = "E://uploaded/"
+ fileDetail.getFileName();


writeToFile(uploadedInputStream, uploadedFileLocation);


String output = "File uploaded to : " + uploadedFileLocation;
System.out.println("uploadFile end");
return Response.status(200).entity(output).build();
}

测试代码：

结果总是报：

HTTP Status 415 - Unsupported Media Type

type Status report

message Unsupported Media Type

description The server refused this request because the request entity is in a format not supported by the requested resource for the requested method.

Apache Tomcat/7.0.39

google 了很多原因如下：

要包含jersey-multipart.jar 和 mimepull.jar  并且要和 jersey-server.jar 版本一致。

调了很据还是会出现以上问题。最后在tomcat的webapps\HTTPtest\WEB-INF\lib里边没有发现Reference Library 里的jar包！

原来我把jar包放在了项目根目录的lib文件夹里了而没有放在WEB-INF文件夹里的lib文件夹里。

改后过段问题解决。
