cor*_*067 1 java multithreading loops
所以,这就是我所拥有的.这是一个使用线程连接到多个客户端的服务器程序.截至目前,该主循环几乎是无限的.假设客户端向ServerThread发送了shutdown命令.ServerThread是否能够访问主类,突破循环并到达程序的末尾?
我尝试在ServerThread中调用isRunning = false,但这似乎不起作用.
public class Server
{
public static boolean isRunning = true;
public static void main(String[] args)
{
// init stuff
try {
serverSocket = new ServerSocket(27647);
} catch (IOException e) {
println("Could not listen on port 27647");
}
while(isRunning)
{
Socket clientSocket = null;
try{
clientSocket = serverSocket.accept();
} catch(IOException e) {
println("Could not connect to client");
}
ServerThread serv = new ServerThread(clientSocket);
serv.start();
}
try {
serverSocket.close();
} catch (IOException e1) { }
}
}

你需要使isRunning变为volatile,你必须关闭serverSocket以取消阻塞接受线程.我建议你有一个方法
public void close() throws IOException {
isRunning = false;
serverSocket.close();
}

如果你从任何线程调用它,线程几乎会立即停止.
