上载文件停止，并在套接字异常上出现意外的 EOF 读取

java tomcat spring spring-mvc

有时，当我尝试在我的远程vps上上传文件时，我得到这个异常（上传过程停止在60%）

06-Jan-2016 11:59:36.801 SEVERE [http-nio-54000-exec-9] org.apache.catalina.core.StandardWrapperValve.invoke Servlet.service() for servlet [mvc-dispatcher] in context with path [] threw exception [Request processing failed;
nested exception is org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request;
nested exception is org.apache.commons.fileupload.FileUploadBase$IOFileUploadException: Processing of multipart/form-data request failed. Unexpected EOF read on the socket]
with root cause
 java.io.EOFException: Unexpected EOF read on the socket

并且在连接中丢失了，就像服务器关闭一样，我得到Google ChromeERR_CONNECTION_ABORTED

我在春季mvc上传这样的文件

public void save_file(MultipartFile upfile , String path){

        try {

            File fichier = new File( path ) ;
            byte[] bytes = upfile.getBytes();
            BufferedOutputStream stream = new BufferedOutputStream(new FileOutputStream( fichier ));
            stream.write(bytes);
            stream.close();
            System.out.println( "You successfully uploaded " + upfile.getOriginalFilename() + "!" );

        } catch (Exception e) {
            System.out.println( "You failed to upload " + upfile.getOriginalFilename() + " => " + e.getMessage() ); ;
        }

}

我的控制器：

@RequestMapping(value = "/administration/upload", method = RequestMethod.POST)
public String Upload_AO_journal(
        @ModelAttribute  UploadForm uploadForm,
                Model map , HttpServletRequest request, HttpSession session ) throws ParseException, UnsupportedEncodingException {

我的豆子

public class UploadForm {

    ...
    public MultipartFile scan;

那么如何解决这个问题呢？

答案 1

你试过直播吗？

JSP 代码：

<form method="POST" onsubmit="" ACTION="url?${_csrf.parameterName}=${_csrf.token}" ENCTYPE="multipart/form-data">

控制器：

 @RequestMapping(
        value = "url", method = RequestMethod.POST
)
public void uploadFile(
        @RequestParam("file") MultipartFile file
) throws IOException {

 InputStream input = upfile.getInputStream();
 Path path = Paths.get(path);//check path
 OutputStream output = Files.newOutputStream(path);
 IOUtils.copy(in, out); //org.apache.commons.io.IOUtils or you can create IOUtils.copy

}

所有这些都适用于春季4.0和春季安全性。

其次，您应该检查http连接是否超时。Chrome 不支持该配置。所以你可以使用火狐，并在这里关注 http://morgb.blogspot.com.es/2014/05/firefox-29-and-http-response-timeout.html。

不确定 upfile 上的 getBytes（）方法。更合适的方法是使用 InputStream，它将管理任何大小的文件，并在必要时进行缓冲。像这样：

public void save_file(MultipartFile upfile , String path){

    try {
        File fichier = new File( path ) ;
        BufferedOutputStream stream = new BufferedOutputStream(new FileOutputStream( fichier ));
        InputStream is = upfile.getInputStream();
        byte [] bytes = new byte[1024];
        int sizeRead;
        while ((sizeRead = is.read(bytes,0, 1024)) > 0) {
            stream.write(bytes, 0, sizeRead);
        }
        stream.flush();
        stream.close();
        System.out.println( "You successfully uploaded " + upfile.getOriginalFilename() + "!" );

    } catch (Exception e) {
        System.out.println( "You failed to upload " + upfile.getOriginalFilename() + " => " + e.getMessage() ); ;
    }

}
