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

我正在创建一个应用程序来发送带有附件的邮件。当我附加一个小的zip文件时，它工作正常，但当我附加一个较大的（>1mb）zip文件时，它返回错误“java.net.SocketException:软件导致的连接中止：套接字写入错误”，我的应用程序挂起

我附加文件的代码是：

 protected void addAtachments(String[] attachments, Multipart multipart)
            throws MessagingException, AddressException {
            System.out.println("attaching");
        for (int i = 0; i <= attachments.length - 1; i++) {
            String filename = attachments[i];

            MimeBodyPart attachmentBodyPart = new MimeBodyPart();
            //use a JAF FileDataSource as it does MIME type detection
            DataSource source = new FileDataSource(filename);
            attachmentBodyPart.setDataHandler(new DataHandler(source));
            attachmentBodyPart.setFileName(filename);
            //add the attachment
            multipart.addBodyPart(attachmentBodyPart);
                 System.out.println("attachment added: " +attachments[i]);
        }

如果附件很小，它可以工作，但发送邮件需要10到11分钟

我正在使用Jfilechooser选择要附加的文件

服务器可能正在超时连接，因为连接时间太长 将消息发送到服务器。打开并关闭协议 跟踪可能提供更多信息

zip文件存储在哪里？是在本地磁盘上，JavaMail

应用程序正在运行？

您有权访问要发送到的邮件服务器吗？很可能是它拒绝了数据，并关闭了你的连接。另外，我们可以看到“套接字写入错误”的完整堆栈跟踪吗？我正在使用gmail服务器发送邮件，当我附加小文件时，它工作正常。但当我尝试附加大文件时，它会出错。我已粘贴了完整的堆栈跟踪。嗨，我已将堆栈跟踪添加到我的问题中。我正在使用JFileChooser从本地磁盘选择zip文件，将对Transport.send的调用替换为对msg.writeTo的调用（new BufferedOutputStream（new FileOutputStream（“msg.txt”））。如果这与发送消息一样慢，那么问题在于读取zip文件和/或构造消息（不太可能）。如果这很快，那么问题在于发送消息所涉及的网络通信。这可能是名称服务查找邮件服务器名称的延迟；尝试将邮件服务器的名称替换为其IP地址。或者问题可能出在您的邮件服务器上，以及它接受您的邮件的速度有多快。网络级协议跟踪可能会帮助您找出延迟的位置。10分钟发送一条消息是不正常的。我下载了网络跟踪软件，我不能理解太多，但它给出了一条消息，作为应用层SMTP服务器慢响应和网络层TCP慢响应。这就是邮件发送延迟的原因吗？对不起，我不知道这是什么意思。我可能需要查看网络跟踪的更多细节，以了解它告诉您的内容。
