对于我的一些Java NIO连接,当我有一个SocketChannel.write(ByteBuffer)调用时,它抛出一个IOException:"Broken pipe".
什么原因导致"管道破裂",更重要的是,是否有可能从该状态恢复？如果它无法恢复,似乎这是一个好的迹象,表明发生了不可逆转的问题,我应该简单地关闭这个套接字连接.这是一个合理的假设吗？是否曾经有一段时间,当IOException套接字连接仍然在第一个地方正确连接时(而不是某个时候失败的工作连接)会发生这种情况？
在一个侧面说明,它是明智的做法始终调用SocketChannel.isConnected()在尝试之前SocketChannel.write(),如果是这样,可以同时假设该连接是"破",如果两者都应该被关闭SocketChannel.isConnected(),并SocketChannel.isConnectionPending()都false？
谢谢!
我有一个我想要写入HttpServletResponse的InputStream.这种方法由于使用byte []而花费的时间太长
InputStream is = getInputStream();
int contentLength = getContentLength();
byte[] data = new byte[contentLength];
is.read(data);
//response here is the HttpServletResponse object
response.setContentLength(contentLength);
response.write(data);
在速度和效率方面,我想知道什么是最好的方法.
在catalina.out我的日志中,我Tomcat7收到由第三方库引起的错误,该库以以下内容开头:
INFO: An error occurred in processing while on a non-container thread. The connection will be closed immediately
java.net.SocketException: Broken pipe
at java.net.SocketOutputStream.socketWrite0(Native Method)
at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:113)
在非容器线程中发生错误的真正含义是什么？
我试图通过Thread从我的应用程序代码中生成一个新的异常来获取类似的日志消息:
new Thread(){
@Override
public void run() {
Integer.parseInt("boom");
}
}.start();
但它导致了
Exception in thread "Thread-28" java.lang.NumberFormatException: For input string: "boom"
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
at java.lang.Integer.parseInt(Integer.java:492)
at java.lang.Integer.parseInt(Integer.java:527)
at ...
所以问题是:当我看到顶部引用的日志时,它意味着什么？在非容器线程中发生错误是什么意思？我该如何重新创建呢？
我在我的服务器上上传了我的war文件,它在部署后完美运行,但一段时间后它显示异常.我正在使用struts2和hibernate

Caused by: …当我尝试将数据发送到客户端浏览器时,我收到此异常.我使用apache POI lib生成一个Excel文件,如下例所示:
workbook = generateData();
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition", "attachment; filename=" + this.filename);
out = response.getOutputStream();
workbook.write(out);
这适用于少量数据,但每次我尝试使用大量数据时它都无法工作.应用程序需要超过30秒才能生成数据,这是否太长,我可以阻止这种情况吗？
