我正在尝试创建一个服务器来发送基于另一个类的计算结果的消息。
我的问题是,由于计算结果来自另一个类,我如何让服务器暂停直到结果准备好,我应该如何将结果传递给我的服务器类并发送结果?
public class MyServer {
ServerSocket providerSocket;
Socket connection = null;
static ObjectOutputStream out;
ObjectInputStream in;
String message;
public static String myServerSend;
BufferedReader data = new BufferedReader(data);
MyServer() {}
void run() {
try {
providerSocket = new ServerSocket(2013, 10);
System.out.println("Waiting for connection");
connection = providerSocket.accept();
out = new ObjectOutputStream(connection.getOutputStream());
out.flush();
in = new ObjectInputStream(connection.getInputStream());
do {
try {
message = (String) in.readObject();
System.out.println("server receive>" + message);
// HERE IS MY QUESTION
// myServerSend is the result from other class,
//How can I pause the server here till myServerSend is ready???????
sendMessage(myServerSend);
} catch (ClassNotFoundException classnot) {
System.err.println("Data received in unknown format");
}
} while (!message.equals("bye"));
} catch (IOException ioException) {
ioException.printStackTrace();
}
}
//write msg into ObjectOutputStream
public static void sendMessage(String msg) {
try {
out.writeObject(msg);
out.flush();
System.out.println("server send>" + msg);
} catch (IOException ioException) {
ioException.printStackTrace();
}
}
