我收到此错误：

ClientAbortException：java.net.SocketException：软件导致连接中止：套接字写入错误

当我尝试下载文件时。这是我的代码：

@RequestMapping("/download")
public String download( Long id, HttpServletResponse response) {

     Version vers=metier.findVersion(id);
     InputStream file= new ByteArrayInputStream(vers.getFileVersion());    
     try {
        response.setHeader("Content-Disposition", "inline;filename=\"" +vers.getFileName()+ "\"");
        OutputStream out = response.getOutputStream();
        IOUtils.copy(file,out);

        out.flush();
        out.close();

    } catch (IOException e) {
        e.printStackTrace();}
    return null;
}

下载成功，但我收到此错误：

我正在使用Spring MVC，Hibernate。有人可以帮我解决这个问题吗？

Answer 1

您正在关闭ServletOutputStream。 AFAIK这不是必需的，可能会导致您看到的消息。尝试发表评论out.close()。

通常情况下，如果您没有打开流，则无需关闭它。 Tomcat应该为您解决这个问题。

Answer 2

尝试以下代码。用以下代码替换您的代码。注释关闭和齐平。它适用于我的情况。

response.setContentType( "text/html" );
response.addHeader( "Content-Disposition", "inline; filename=" + file.getName() );
response.addHeader( "Content-Length", Long.toString( file.length() ) );
IOUtils.copy(file, response.getOutputStream());
//out.flush();
//out.close();

Answer 3

尝试以下代码。用以下代码替换您的代码。评论同花顺。它适用于我的情况。

＆＃13;

response.setContentType( "text/html" );
response.addHeader( "Content-Disposition", "inline; filename=" + file.getName() );
response.addHeader( "Content-Length", Long.toString( file.length() ) );
IOUtils.copy(file, response.getOutputStream());
//out.flush();
out.close();

＆＃13;

我想在很多情况下，因为他们不知道close（）也会调用flush（），所以他们想要安全。

无论如何，使用缓冲流应该使手动刷新几乎是多余的。
