java rmi 两种方式 固定端口设置

2. Registry  绑定方式
3. UserManagerImpl userManager=new UserManagerImpl(); 
4.             UserManagerInterface userManagerI=(UserManagerInterface)UnicastRemoteObject.exportObject(userManager,0); //固定端口设置
5.             // Bind the remote object's stub in the registry 
6.             Registry registry = LocateRegistry.createRegistry(2001); 
7.             registry.rebind("userManager", userManagerI); 
8.             System.out.println("server is ready"); 

   获取对象

Registry reg = LocateRegistry.getRegistry("localhost");
        stub = (Payment) reg.lookup("Mortgage");

Naming 绑定对象

public class Server extends java.rmi.server.UnicastRemoteObject implements aRemoteInterface{
    public Server(int port) {
         super(port);
    }
    ....
    Naming.bind(uniqueName, this);
    ....
}
Naming获取对象

Naming.lookup()

 

固定端口这只

1. publicclass SMRMISocket extends RMISocketFactory {
2. public Socket createSocket(String host, int port) throws IOException{
3. returnnew Socket(host,port);
4. }
5. public ServerSocket createServerSocket(int port) throws IOException {
6. if (port == 0)
7. port = 10990; //不指定就随机分配了
8. returnnew ServerSocket(port);
9. }
10. }

在实例化UnicastRemoteObject的子类前加入一下代码：

 

try {
RMISocketFactory.setSocketFactory(new SMRMISocket());
} catch (Exception ex) {
}
