Wildfly Jakarta EE 10 多部分表格缺失

Question

在从 Wildfly 25 升级到 Wildfly 27（及更高版本）的过程中，我们不再看到多部分表单。

请求部分为空（见下面底部）。所以，我不知道它在哪里被吃掉。

这是 web.conf

这是我想查看多部分数据的地方。

    @MultipartForm
    public void parsePostRequestInputs(HttpServletRequest request, InputValidation validator) throws IOException
    {
        _filesToUpload = new HashMap<String, Part>();

        if (request.getContentType().contains("urlencoded"))
        {
            //
            // read the request
            //
            Map<String, String[]> params = request.getParameterMap();
            _entries = new String[params.keySet().size()];
            int pos = 0;
            for (String param : params.keySet()) {
               _entries[pos] = param + "=" + URLDecoder.decode(params.get(param)[0], StandardCharsets.UTF_8);
               pos++;
            }
        }
        else
        {
            _log.debug("Checking for multipart.");

            try {
                request.getParts();
            } catch (Exception e) {
                _entries = new String[0];
                return;
            }

            try
            {
                final Collection<Part> parts = request.getParts();
                List<String> temp = new ArrayList<String>();
                for (final Part part : parts)
                {
                    String fileItemFieldName = part.getSubmittedFileName();
                    if (!(fileItemFieldName.startsWith("fileUpload")))
                    {
                        temp.add(part.getName() + "=" + fileItemFieldName);
                    }
                    else
                    {
                        String index = part.getName().substring(10);
                        _filesToUpload.put(index, part);

                        String fileItemName = part.getName();
                        if (fileItemName.length() > 30)
                        {
                            fileItemName = fileItemName.substring(0, 30);
                        }
                        temp.add("uploadPixName" + index + "=" + fileItemName);
                    }
                }
                _entries = temp.toArray(new String[temp.size()]);
            }
            catch (FileUploadException | ServletException e)
            {
                _log.error("There was an issue uploading files for the POST request. " + e);
            }
        }
    }

请求在调试器中看起来像这样：

request = {HttpServletRequestImpl@16372} "HttpServletRequestImpl [ POST /esg/client ]"
 exchange = {HttpServerExchange@16383} "HttpServerExchange{ POST /esg/client}"
 originalServletContext = {ServletContextImpl@16384} 
 servletContext = {ServletContextImpl@16384} 
 attributes = null
 servletInputStream = null
 reader = null
 cookies = null
 parts = null
 asyncStarted = false
 asyncContext = null
 queryParameters = null
 parsedFormData = null
 formParsingException = null
 characterEncoding = null
 readStarted = false
 sessionCookieSource = null

我们所有的多部分数据请求都会发生这种情况。这也许是最简单的要求。如果我们将 get 与 URL 编码一起使用，一切都会正常。有什么想法多部分数据去了哪里吗？

看来多部分 servlet 需要定义多部分配置（或有适当的注释）。我不确定何时需要这样做。然而，它出现在我们从 Wildfly 26 到 Wildfly 27 的迁移中。

通过修改我的 web.xml 来定义多部分配置，一切开始工作。

<servlet>
    <display-name>ESG Client Servlet</display-name>
    <servlet-name>esg.ClientServlet</servlet-name>
    <servlet-class>com.oberon.esg.client.ClientServlet</servlet-class>
    <load-on-startup>4</load-on-startup>
    <multipart-config>
        <location>/tmp</location>
        <max-file-size>20848820</max-file-size>
        <max-request-size>418018841</max-request-size>
        <file-size-threshold>1048576</file-size-threshold>
    </multipart-config>
</servlet>
