我们java.net.SocketException: Connection reset在日志中看到频繁但间歇性的 错误.我们不确定Connection reset错误实际来自何处,以及如何进行调试.
该问题似乎与我们尝试发送的邮件无关.请注意,消息不是 connection reset by peer.
有关此异常的典型原因可能是什么的建议,以及我们如何进行？
这是一个代表性的堆栈跟踪(com.companyname.mtix.sms是我们的组件):

我的servlet程序是
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition","attachment;filename="+filename);
FileInputStream in = new FileInputStream(new File(filepath));
ServletOutputStream output=response.getOutputStream();
byte[] outputByte=new byte[4096];
while(in.read(outputByte,0,4096)!=-1){
output.write(outputByte,0,4096);//error indicates in this line

in.close();
output.flush();
output.close();
如何解决这个问题？
我正在尝试将图像从Java桌面应用程序发送到J2ME应用程序.问题是我得到了这个例外:
java.net.SocketException: Software caused connection abort: socket write error
我在网上四处看看,尽管这个问题并不罕见,但我无法找到具体的解决方案.我在传输之前将图像转换为字节数组.这些是分别在桌面应用程序和J2ME上找到的方法
public void send(String ID, byte[] serverMessage) throws Exception
{
//Get the IP and Port of the person to which the message is to be sent.
String[] connectionDetails = this.userDetails.get(ID).split(",");
Socket sock = new Socket(InetAddress.getByName(connectionDetails[0]), Integer.parseInt(connectionDetails[1]));
OutputStream os = sock.getOutputStream();

我怎么解决这个问题？
我试图中止套接字连接,以便另一端的客户端将获得"WSAECONNABORTED(10053)软件导致连接中止".轮询连接时出现错误消息.
Close()和Shutdown()将正常断开连接.我不想要一个优雅的断开连接.我想做一次Abort,以便客户感觉到出了什么问题.
谢谢,
编辑:我正在编写服务器编码,我想中止套接字连接客户端
所有。我已经遇到了几天的问题，这是详细信息堆栈信息：
org.springframework.dao.RecoverableDataAccessException:

; SQL …我想忽略/静音的例外如下：
Resolved exception caused by handler execution: org.apache.catalina.connector.ClientAbortException: java.net.SocketException: Software caused connection abort: socket write error
并且仅在我使用 Firefox 访问应用程序时引起。
欢迎任何想法。
在@CodeRider 的回答之后，我编辑了我的异常处理程序并使用了以下条件 if(exception instanceof ClientAbortException && response.isCommitted()){return null;}
当我处于调试模式时，我可以看到我确实返回了 null 而不是 super.doResolveException()。
但是，我仍然可以在控制台中看到该异常。这是完整的堆栈跟踪：

我已经做了一些挖掘尝试修复这个奇怪的Socket异常,但无济于事.
一些论坛解决方案建议为Hibernate实现一个c3p0连接池.没有问题.
其他人建议禁用AV和防火墙(!!),因为这些可能会干扰套接字连接.没有问题.
我用Hibernate标记了这个问题,因为我不确定hibernate是什么原因,但Hibernate调用(运行查询)会出现异常.应用程序中的其他Hibernate代码工作正常.Hibernate版本是3.2.

非常感谢帮助.这有点奇怪.

这基本上是图片:我有一个服务器和一个客户端(通过localhost操作).服务器为每个连接创建一个客户端线程.这个新线程在读取等待来自客户端的消息时阻塞.随意,我可以通过GUI停用服务器,GUI将(从主线程)"断开"发送到客户端,然后关闭输出流,唤醒被阻止的客户端线程,然后通过关闭套接字完成(我认为在关闭输出流之后这种关闭是不必要的,但无论如何).
客户端:连接请求后,它会休眠10秒,写入断开连接消息并通过char读取答案字符.
问题:
在该10秒客户端休眠时间内停用服务器后,客户端从服务器正确读取"断开连接"消息.但是,如果我只为每个char读取添加一个虚拟打印(在while循环内),则最终读取的结果会发生变化.有时它会正确读取服务器的"断开连接",有时会读取"disco"或类似的变体,并抛出此异常:
"Java异常:"软件导致连接中止:recv失败"
有关添加少量打印件的原因有何建议可以创建此结果？我会假设另一端有一个封闭的套接字对读取消息没有影响.我发现有关recv错误的其他线程提到超时,我猜测在使用localhost时应该不会发生这种情况？
我正在TCP上创建一个java客户端/服务器应用程序,我们有两个套接字:
我在Server中创建了两个ServerSockets,以便
通过接受ServerSockets 来创建Socket One和Two
.
首先,客户端通过第一个Socket发送一些字节,
以便它可以告诉服务器它需要哪个文件.
然后服务器通过第二个套接字将文件发送到客户端.
客户端收到文件后,尝试向服务器发送一个Transfer Done Message.
在那里,我得到了关闭套接字的异常.
但是我直到现在才关闭套接字.
我只关闭发送文件的缓冲区.
即使我在发送文件后尝试再次打开socketInputStream,错误仍然是相同的.
此外,如果我不关闭发送文件的缓冲区,客户端将不会获取该文件.
服务器异常
返回消息中的错误 - java.net.SocketException:socket已关闭
客户端例外
服务器响应 - java.net.SocketException:软件导致连接中止:套接字写入错误
我究竟做错了什么？
