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

【中文标题】java.net.SocketException：软件导致连接中止：套接字写入错误[重复]【英文标题】：java.net.SocketException: Software caused connection abort: socket write error [duplicate] 【发布时间】：2012-01-05 00:51:55 【问题描述】：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，它工作得很好，但是当我附加一个更大的（> 1mb）zip 文件时，它返回错误“java.net.SocketException：软件导致连接中止：套接字写入错误”并且我的应用程序挂起。
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]);
另外，有没有什么方法可以使用 javamail 更快地附加文件？发送附加消息花费了太多时间。

如果附件很小，它可以工作，但需要 10 到 11 分钟才能发送邮件
我正在使用 Jfilechooser 选择要附加的文件
【问题讨论】：
您是否有权访问您要发送到的邮件服务器？它很可能会拒绝数据并关闭您的连接。另外，我们能看到“socket write error”的完整堆栈跟踪吗？ 我正在使用 gmail 服务器发送邮件，当我附加小型文件时它工作得很好。但是当我尝试附加更大的文件时它会出错。我已经粘贴了完整的堆栈跟踪。 【参考方案1】：服务器可能正在超时连接，因为它花费的时间太长 将消息发送到服务器。打开session debugging和协议 trace 可能会提供更多信息。
压缩文件存储在哪里？是在JavaMail所在的本地磁盘上吗 应用程序正在运行吗？
【讨论】：
嗨，我已将堆栈跟踪添加到我的问题中。我正在使用 jfilechooser 从本地磁盘中选择 zip 文件 将您对 Transport.send 的调用替换为对 msg.writeTo(new BufferedOutputStream(new FileOutputStream("msg.txt"))) 的调用。如果这与发送消息一样慢，那么问题在于读取您的 zip 文件和/或构建消息（不太可能）。 如果速度很快，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，以及它愿意多快接受您的邮件。网络级协议跟踪可能会帮助您找出延迟在哪里。 10分钟发送一条消息是不正常的。 我下载了网络跟踪软件，我无法理解，但它给出了一条消息，因为应用层的 SMTP 服务器响应慢，网络层的 TCP 响应慢。这是发送消息延迟的确切原因吗？ 对不起，我不知道那是什么意思。我可能需要查看网络跟踪的更多详细信息才能了解它告诉您的内容。以上是关于java.net.SocketException：软件导致连接中止：套接字写入错误[重复]的主要内容，如果未能解决你的问题，请参考以下文章
