Java 将文件上载到Spring时，net:：ERR_连接中止的可能原因是什么

pI am使用plupload（plupload.com）jQuery插件将图像文件AJAX到JavaSpring服务器。我尝试了服务器端RESTful控制器端点的不同实现。我附上了处理文件上传url的具体方法。任何帮助都将不胜感激。多谢各位

@RequestMapping(value = "/pictureUpload", method = RequestMethod.POST )
public @ResponseBody 
String productPictureUploadPost(@RequestBody MultipartFile multipartFile) {
    HomeController.logger.info("In method productPictureUploadPost in SettingsPanelController. : Entering");
    String orgName = multipartFile.getOriginalFilename();

    String filePath = "/my_uploads/" + orgName;
    File dest = new File(filePath);
    try {
        multipartFile.transferTo(dest);
    } catch (IllegalStateException e) {
        e.printStackTrace();
        return "File uploaded failed:" + orgName;
    } catch (IOException e) {
        e.printStackTrace();
        return "File uploaded failed:" + orgName;
    }
    HomeController.logger.info("In method productPictureUploadPost in SettingsPanelController. Exiting : " + "File uploaded:" + orgName);   
    return "File uploaded:" + orgName;
}

我还附加了servlet.xml多部分解析器声明

<bean class="org.springframework.web.multipart.support.StandardServletMultipartResolver"/>

在文件上载的上下文中，当HTTP服务器未完全读取客户端的HTTP请求正文并在上载过程中中止连接时，会发生

net:：ERR_CONNECTION_ABORTED

。这通常发生在上载的文件太大时，服务器继续读取请求并提前失败是没有意义的

中止连接意味着客户端在收到响应之前上传文件不会浪费带宽，但会触发上述错误

HTTP提供了提前终止连接的功能，

Expect:100 continue

请求头和

100 continue

响应状态，您可以在此处阅读：

不幸的是，大多数浏览器不会在文件上载（）期间发送它

---

但是，由于您在客户端使用Flash/Silverlight进行上传，我建议您考虑让您的上传小部件向服务器发送

Expect:100 continue

。

您从哪里得到错误？在浏览器中，通过firebug。看起来不像是Spring错误。可能是浏览器设置或防火墙问题，我只是在寻找一些类似问题的经验，以便在排除故障时缩小范围。

$(document).ready(function() {
$("#uploader").plupload({
    // General settings
    runtimes: 'html5,flash,silverlight,html4',

    url: "/pictureUpload",

    // Maximum file size
    max_file_size: '1000mb',

    // User can upload no more then 20 files in one go (sets multiple_queues to false)
    max_file_count: 3,

    // Specify what files to browse for
    filters: [
        { title: "Image files", extensions: "jpg,jpeg,gif,png" }
    ],

    // Rename files by clicking on their titles
    rename: true,

    // Sort files
    sortable: true,

    // Enable ability to drag'n'drop files onto the widget (currently only HTML5 supports that)
    dragdrop: true,

    // Views to activate
    views: {
        list: true,
        thumbs: true, // Show thumbs
        active: 'thumbs'
    },
