编辑:我解决了我的问题:
while(!finish.equals("readline")){
publish(finish);
finish = Main.in.readLine();
}
必须改为:
while(true){
publish(finish);
finish = Main.in.readLine();
}
老问题:
我正在用 Java 编写一个聊天应用程序,我制作了一个简单的 Gui,它运行良好。但现在我已经重写了收集聊天消息的部分,使其成为线程安全的。登录时,服务器将聊天中的所有消息推送到客户端,这很好用。在那一刻之后,GUI继续响应,我可以发送命令并且它们到达服务器但是没有调用过程方法,所以没有返回任何内容。我究竟做错了什么?
这是我正在谈论的代码:
package Client;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;
import java.net.UnknownHostException;
import java.util.List;
import javax.swing.SwingWorker;
public class ChatReceiver extends SwingWorker<Void, String> {
@Override
protected Void doInBackground() {
try {
Main.echoSocket = new Socket(Main.ip, 4444);
Main.out = new PrintWriter(Main.echoSocket.getOutputStream(), true);
Main.in = new BufferedReader(new InputStreamReader(
Main.echoSocket.getInputStream()));
} catch (UnknownHostException e) {
System.err.println("Don't know about host.");
} catch (IOException e) {
System.err.println("Couldn't get I/O for "
+ "the connection to: localhost.");
}
publish("Sending Login-Request...");
Main.out.println("login");
try {
String text = Main.in.readLine();
String status = Main.in.readLine();
publish("Receiving: " + text + " " + status);
if(status.equals("readline") && text.equals("ready")){
String finish = "logging in...";
Main.out.println(Main.name + " SZUTKEY");
while(!finish.equals("readline")){
publish(finish);
finish = Main.in.readLine();
}
}else{
throw new RuntimeException("Fuck it login died!");
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
@Override
protected void process(List<String> chats) {
Main.printTest("xxx");
for(String s : chats.toArray(new String[0])){
Main.printTest("called");
Main.printTest(s);
}
Main.textField.validate();
Main.textField.repaint();
}
}
这在我的 Gui 中被调用:
loginAction = new AbstractAction("Login") {
/**
*
*/
private static final long serialVersionUID = -3279591081543889275L;
@Override
public void actionPerformed( ActionEvent arg0 ) {
name = JOptionPane.showInputDialog("Please input your Chatname");
ip = JOptionPane.showInputDialog("Please input the Chatserver-IP", "localhost");
(chat = new ChatReceiver()).execute();
}
};
