Java 无法在Weblogic服务器上使用Fileupload Multipart

在docker上请求Weblogic 12.2.1.4-dev中的servlet部分时出现阻塞异常。（请注意，这在Wildfly服务器上工作）

我使用的Java代码是：

import javax.servlet.http.*;

protected void doPut(HttpServletRequest request, HttpServletResponse response) throws IOException {
    ...
    Collection<Part> parts = request.getParts();
    ...
}

我也面临同样的问题

WebLogic核心库中FileUpload的servlet实现仅允许“POST”方法下的多部分请求：

如果此验证失败，它将引发异常，包括与实际错误没有任何关系的消息：

    if (!isMultipart())
      throw new ServletException("The request content-type is not a multipart/form-data"); 

---

因此，我将方法从PUT切换到POST。

是否使用方法request.getContentType（）检查容器中到达请求的内容类型值@RokProdan request.getContentType（）：“多部分/表单数据；边界=----WebKitFormBoundaryDMBJ9xysJG9IK0D”您使用的是哪个版本的Servlet API？您的servlet类是否如中所述使用@MultipartConfig进行注释？我使用的是：

javax.servlet-api v3.1.0

，我的servlet类有以下两个注释：

@WebServlet（value=“/service”，loadOnStartup=1）@MultipartConfig（location=“/tmp”，fileSizeThreshold=1024*1024，maxFileSize=1024*1024*30，maxRequestSize=1024*1024*5*5）

请注意，文件上载在Widlfly服务器上运行正常

    if (!isMultipart())
      throw new ServletException("The request content-type is not a multipart/form-data");
