我无法理解简单的事情。我有一个处理套接字输入的类。我有一个捕获子句:
public class EntryPoint implements Runnable {
private Socket socket = null;
private BufferedReader br = null; // receives data from the destination
...
public void run() {
String command = null; // buffer for holding one request from command line
StringReader commandReader = null; // stream for reading command
try {
while (!socket.isClosed() && (command = br.readLine()) != null) {
try {
command = command.trim();
commandReader = new StringReader(command);
Request req = JAXB.unmarshal(commandReader, Request.class);
commandReader.close();
dispatcher.sendRequest(req);
} catch(DataBindingException ex) {
response.sendResponse(SystemMessageFactory.INVALID);
response.sendResponse(SystemMessageFactory.SOCKET_SHUTDOWN);
}
}
} catch (SocketException e) {
System.out.println("Socket Exception");
} catch (IOException e) {
Logger.getLogger("server").log(Level.SEVERE,
"Error reading the command input of the client!", e);
}
}
}
当对等方突然关闭套接字时，会发送连接重置。堆栈跟踪是:
16.07.2013 1:39:51 EntryPoint run
SEVERE: Error reading the command input of the client!

这怎么可能？我都抓到两次了! SocketException 在其自己的 catch 子句和 IOException catch 子句中被捕获。但什么也没发生!它不会捕获套接字异常。我该如何处理它以及造成这种行为的原因是什么？
最佳答案
SocketException 要么不是 java.net 中的那个。 检查您的导入。
或者您没有运行您认为的代码。
