Question

我有一个属于Web应用程序的表单，其中包含一个“文件”字段来上传pdf文件。（spring 3环境，多部分文件上传）上传文件在测试环境（所有浏览器）中都能正常工作，并且只适用于生产环境中的Firefox（文件上传导致连接重置异常，特别是低互联网连接客户端浏览器）

按下提交按钮几秒后抛出以下异常:(浏览器是在Windows环境中运行的IE / Chrome，但不是Firefox）

以下是网络应用程序代码和配置：

spring multipart resolver配置：

控制器：

/**      
 * this controller handles file upload and save files to dao.
     * @author Christophe.Dumonet@ifma.fr
     * @param request
 * @param documentFormBean
 * @param result
 * @param file
 * @return
 */
@RequestMapping(value = "/save", method = RequestMethod.POST)
public ModelAndView save(HttpServletRequest request,
        @Valid DocumentFormBean documentFormBean,BindingResult result,
        @RequestParam("file") MultipartFile file) {
    ResourceBundle bundle = ResourceBundle.getBundle("messages", request.getLocale());

    Map<String,Object> map = new HashMap<String, Object>();

    map.put("documentFormBean", new DocumentFormBean());
    map.put("documentList", documentDao.findAllForaDepot(Long.parseLong((String) request.getParameter("depot"))));
    map.put("depot", depotDao.find(Long.parseLong((String) request.getParameter("depot"))));

    //Handle too many documents attached : how many documents attached to this depot now ? throw an error to UI.
    @SuppressWarnings("rawtypes")
    List documentAttached = documentDao.findAllForaDepot(Long.parseLong((String) request.getParameter("depot")));
    if (documentAttached != null && documentAttached.size() >= Integer.parseInt(SpringPropertiesUtil.getProperty("Depot.maximum.file.number.authorized"))){
        map.put("MaximumFileNumberReached", bundle.getString("Depot.maximum.file.number.errormessage"));
        return new ModelAndView("ajoutDocumentsRapport", map);
    }

    //handle file empty or not pdf
    if (result.hasErrors() || (file.isEmpty()) || !file.getContentType().contains("pdf")) {
        map.put("errors", result);

        if (file.isEmpty()) map.put("ErrorMessageFileEmpty", bundle.getString("view.addrapport.error.fileisempty"));

        if (!file.getContentType().contains("pdf")) map.put("ErrorMessageFileTypeNotPDF", bundle.getString("view.addrapport.error.filetype.onlypdf"));
        return new ModelAndView("ajoutDocumentsRapport", map);
    } else{


    try {
        //Blob blob = Hibernate.createBlob(file.getInputStream());
        //cause Hibernate.createBlob is deprecated, use a LobHelper interface instead.
        org.hibernate.Session se = (org.hibernate.Session)depotDao.getHibernateTemplate().getSessionFactory().getCurrentSession();
        LobHelper lh = se.getLobHelper();
        Blob blob = lh.createBlob(file.getBytes());

        Document newDocument = new Document();
        newDocument.setDescription(documentFormBean.getDescription());
        newDocument.setContentType(file.getContentType());
        newDocument.setFilename(file.getOriginalFilename());
        newDocument.setContent(blob);
        newDocument.setDepot(depotDao.find(Long.parseLong((String) request.getParameter("depot"))));
        documentDao.save(newDocument);
        map.put("documentList", documentDao.findAllForaDepot(Long.parseLong((String) request.getParameter("depot"))));
        } catch (IOException e) {
        e.printStackTrace();
    }

    return new ModelAndView("ajoutDocumentsRapport",map);
    }
}

Tomcat 6 AJP连接器连接器配置：（原始配置是：）

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443"/>

（也试过这个：）

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443"
             connectionTimeout="120000" maxThreads="1000"
            minSpareThreads="50" maxSpareThreads="100" enableLookups="false"
            acceptCount="150" address="127.0.0.1"
            useBodyEncodingForURI="true"
            compression="on"
            compressionMinSize="1024"
            compressableMimeType="text/html,text/xml"
            connectionUploadTimeout="3600000"
            disableUploadTimeout="true"
    />

Apache 2虚拟主机配置：

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www
    Timeout 3600
    ProxyPass / ajp://localhost:8009/
    ProxyPassReverse / ajp://localhost:8009/
    ProxyTimeout 3600

    <Proxy *>
    Order deny,allow
    Allow from all
    </Proxy>

    <Directory /var/www/>
            Options -Indexes FollowSymLinks MultiViews
            AllowOverride None
            Order allow,deny
            allow from all
    </Directory>

     ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
     ErrorLog ${APACHE_LOG_DIR}/error.log
     LogLevel warn
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

这种例外的可能原因是什么？
文件上传时的连接重置通常意味着客户端中止发送...那么什么？任何帮助将不胜感激。 Christophe D.

Answer 1

您是否可以在客户端和服务器之间捕获tcpdump，并查看谁正在重置连接。我们的应用程序中有一个类似的问题，它是一个防火墙，正在放弃连接。 apache [LimitRequestBody]中还有另一个设置，即在文件上传达到该限制后中止上传。在这两种情况下，来自apache和mod-jk的日志在这些情况下调试并不是很清楚。
