我有一个简单的网络应用程序，它只有一个接受数据文件并将其保存到服务器的 Servlet。我正在使用“ apache commons FileUpload ”库。文件上传在我的本地服务器上工作正常（我将 Glassfish 用于我的开发和生产服务器）。我可以上传任何大小的文件。这是我的内存信息：

-XX:MaxPermSize=512m
-Xmx1024m

这是我的 servlet 的代码：

...
public void doPost(HttpServletRequest request, HttpServletResponse response)  throws ServletException, IOException {
    log.info("Let's try to do something with your request");
    getMultipartRequestFile(request);
}

// Handling uploaded file with commons-fileupload library
private void getMultipartRequestFile(HttpServletRequest request){

    if(!ServletFileUpload.isMultipartContent(request))          // if not is multi part then exit this function
        return;

    FileItemFactory factory = new DiskFileItemFactory();        // Create a factory for file items
    ServletFileUpload upload = new ServletFileUpload(factory);  // Create a new file upload handler

    //Create a progress listener
    ProgressListener progressListener = new ProgressListener(){
        private long megaBytes = -1;
           public void update(long pBytesRead, long pContentLength, int pItems) {
               long mBytes = pBytesRead / 1000000;
               if (megaBytes == mBytes) {
                   return;
               }
               megaBytes = mBytes;
               if (pContentLength == -1) {
                   log.info("So far, " + dec.format(pBytesRead/1024.0/1024.0) + " have been read.");
               } else {
                   log.info("So far, " + dec.format(pBytesRead/1024.0/1024.0) + "\tof " + dec.format(pContentLength/1024.0/1024.0));
               }
           }
    };
    upload.setProgressListener(progressListener);

    // Parse the request
    try {
        List items = upload.parseRequest(request);

        // Process the uploaded items
        Iterator iter = items.iterator();
        while (iter.hasNext()) {
            FileItem item = (FileItem) iter.next();

            if (item.isFormField()) {
                processFormField(item);
            } else {
                processUploadedFile(item);
            }
        }
    } 
    catch (FileUploadException e) {
        e.printStackTrace();
    }
}

// this is where all magic with the file will happen
private void processUploadedFile(FileItem item){

    if (!item.isFormField()) {

        String fieldName = item.getFieldName();
        String fileName = item.getName();
        String contentType = item.getContentType();
        boolean isInMemory = item.isInMemory();
        long sizeInBytes = item.getSize();

        log.info("Field name: " + fieldName + "\nFile Name: " + fileName + "\nContent type: " +contentType+ "\nSize: " + dec.format(sizeInBytes/1024.0/1024.0));

        // write uploaded file to hdd
        File uploadedFile = new File(FILES_FOLDER + fileName);  

        try {
            item.write(uploadedFile);           
            log.info("File location: " + FILES_FOLDER + fileName);

        } catch (Exception e) {
            log.warning("File cannot be writtet to the disc");
            e.printStackTrace();
        }
    }
}
...

这是带有错误的输出：

这是我还尝试添加到我的 domain.xml 的内容：

<http-listener acceptor-threads="1" address="0.0.0.0" blocking-enabled="false" default-virtual-server="server" enabled="true" family="inet" id="http-listener-1" port="8080" security-enabled="false" server-name="" xpowered-by="true">
          <property name="maxPostSize" value="0"/> <!-- 0 means no max -->
          <property name="proxiedProtocols" value="ws/tcp"/>
</http-listener>

知道为什么会这样

检查两者上 glassfish 服务器的版本。我遇到了同样的问题，并发现 apache commons 文件上传在 glassfish 服务器 3.1.2 上存在问题。当我升级到服务器版本 3.1.2.2（构建 5）时，文件上传功能工作正常。

请参考以下问题http://java.net/jira/browse/GLASSFISH-18444

我只能推测。您是否在两台服务器上使用相同版本的库/容器？您能否嗅探您的文件上传（使用 apache 工具 - 不记得名称）并检查它是否正确上传？您可以在 servlet 中手动抓取上传的正文并检查 servlet 过滤器/默认请求解析器是否没有损坏？

我在这里也发现了这个问题。基本上它指出上传期间的套接字超时导致异常。

java.lang.IllegalStateException: PWC4662: Request header is too large

您需要配置 HTTP 连接器以使用更大的缓冲区。

在 HTTP 监听器的设置中应该有一个参数“maxPostSize”。
