我遇到项目迁移问题。 我使用 Netbeans 7.4 创建了一个Web应用程序，使用来自netbeans库和其他自制库的 Jersey 2 ， JSF 2 。 现在，我使用 maven 转移到 Netbeans 8.1 来管理库依赖项。新旧网络应用都使用 Tomcat 7
使用旧的源码，我使用multipart的webservices工作正常。对于新版本，请求似乎是空的。
以下是代码（旧版和新版的 SAME 代码，但新代码现在使用maven）：
@POST
@Produces("application/pdf")
@Path("produce/{checksum}")
@RolesAllowed("admin")
public Response produce(@Context HttpServletRequest request, @PathParam("checksum") String checksum, @Context SecurityContext sc) {
l.info(String.format("Produce request by user %s received at %s ", sc.getUserPrincipal().getName(), new Date()));
try {
File tempInputXml = File.createTempFile("input", ".xml");
File tempZip = File.createTempFile("zip", ".zip");
List<Part> parts = new ArrayList(request.getParts());
l.info(String.format("%d parts", parts.size()));
InputStream inputStream = null;
if (parts.isEmpty()) {
l.info("No part in the request, try other way");
inputStream = request.getInputStream();
} else {
Part firstPart = parts.get(0);
l.info(String.format("ContentType part 0: %s", firstPart.getContentType()));
try (OutputStream os = new FileOutputStream(tempZip)) {
IOUtils.copy(firstPart.getInputStream(), os);
}
}
...
byte[] pdfContent = ....;
return Response.ok(pdfContent).build();
}
request.getParts().isEmpty()始终为true，而旧版本则为<dependencies>

。
这是新版本的pom.xml：
File temp = ...;
String md5 = md5Sum(temp);
String realUrl = "http://localhost:8080/soft/api/ws/produce/" + md5;
HttpPost httppost = new HttpPost(realUrl);
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.addBinaryBody("xml", temp);
HttpEntity multipart = builder.build();
httppost.setEntity(multipart);
HttpResponse response = httpclient.execute(httppost);
这是客户端代码（我不能遗憾地改变它）
FormDataMultiPart当我尝试使用@Context HttpServletRequest时，客户端会收到415 HTTP错误。使用旧版本的PsiFile psiFile = e.getData(CommonDataKeys.PSI_FILE);
if (psiFile instanceof PsiJavaFile) {
PsiClass[] classes = ((PsiJavaFile) psiFile).getClasses();
// and so on
}
，它工作正常
我的错误在哪里？
