java.net.SocketException: Connection reset和java.net.SocketException: Broken Pipe之间的区别是什么？

我想弄清楚这两个例外的原因是什么。我们的服务器上出现以下错误，基本上是基于SOAP的Web服务。当我尝试中止客户端调用我看到的异常是Broken pipe ...

以下是我们的堆栈跟踪，感谢任何帮助！

Answer 1

这些是TCP协议级别的错误条件。它们都基本上意味着另一方关闭了TCP连接。不同之处在于发生的沟通阶段。

Answer 2

读取或写入时可能会发生“连接重置”。 '断管'只能在写字时出现。两者都是由写入已经被另一端关闭的连接引起的，或者是由于其他原因而被重置的。

Answer 3

当对等方关闭连接时（即在另一方持有连接的应用程序），会出现Connection reset和Broken pipe。

在写作（见java.net.SocketOutputStream）或阅读（见java.net.SocketInputStream）时可能会发生{p> Connection reset。

Broken pipe出现在java.net.SocketException

的Native方法中

java.net.SocketException: Broken pipe
    at java.net.SocketOutputStream.socketWrite0(Native Method)
    at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:92)

因此，Broken pipe发生在较低的沟通水平，正如Michael Borgwardt所建议的那样。

在大多数情况下，我在向客户端浏览器发送大型PDF时看到此错误，并且用户在获取整个文档之前杀死了浏览器（在这种情况下，我只是忽略了错误，因为这是用户选择关闭它浏览器，没有什么可以纠正的）。但也可能是其他原因（例如EJP suggests more reason related to data communication protocols）。

Answer 4

两者似乎都指向类似的情况 - 远程套接字不再可用于写入。

最近通过我的实验，我发现当我的服务器在Unix环境中时，就会发生Broken管道，我终止了客户端。

015-06-26 10:53:51,028-0400 [ERROR][WS-ASync] (Handler.java:1168) Exception while writing ClientAbortException:  java.net.SocketException: Broken pipe

    at org.apache.tomcat.util.buf.ByteChunk.append(ByteChunk.java:371)
    at org.apache.catalina.connector.OutputBuffer.writeBytes(OutputBuffer.java:438)

然而，当服务器在Windows上运行时，我看到连接重置异常

2015-06-26 09:11:31,491 ERROR [WS-ASync] (Handler.java:1168) - Exception while writing ClientAbortException:  java.net.SocketException: Connection reset by peer: socket write error

java.net.SocketException有什么区别：Connection reset和java.net.SocketException：Broken Pipe？
