我已经使用RMI创建了一个服务器和客户端程序。但是,无论何时我在命令提示符中启动rmiregistry并运行我的服务器后,都会抛出端口已被使用的错误。只有我自己启动了rmiregistry。我已经从netstat检查过了。
服务器代码:
public class Server implements Runnable, Linker{
private static Server server = null;
private static Linker l = null;
private String name = null;
public Server(){}
public void setName(String name){
this.name = name;
}
public String getName(){
return name;
}
public void run(){
while(!("Andy").equalsIgnoreCase(name)){
}
}
public static void createStub(){
try{
server = new Server();
l = (Linker) UnicastRemoteObject.exportObject(server, 1099);
Registry registry = LocateRegistry.getRegistry();
registry.bind("Link", l);
System.out.println("Ready");
}
catch(Exception e){
e.printStackTrace();
}
}
public static void main(String[] args) {
// TODO Auto-generated method stub
createStub();
Thread t = new Thread(server);
}
}
客户端代码:
public class Client implements Runnable{
private Scanner sc = new Scanner(System.in);
private Linker linker = null;
public void loadStub(){
try{
Registry registry = LocateRegistry.getRegistry(1099);
linker = (Linker) registry.lookup("Link");
}catch(Exception e){
}
}
public void run(){
String ip = null;
while(sc.hasNext()&&!(ip = sc.nextLine()).equalsIgnoreCase(":q")){
try {
linker.setName(ip);
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
public static void main(String...args){
Client client = new Client();
client.loadStub();
Thread t = new Thread(client);
t.start();
}
}
异常:
java.rmi.server.ExportException: Port already in use: 1099; nested exception is:
java.net.BindException: Address already in use: JVM_Bind
