启动终端时客户端启动 RMIregistry 不起作用

Question

每当我尝试运行java时，我都可以打印出系统已启动，但不能打印出导出和绑定

import java.rmi.server.UnicastRemoteObject;  //!! To use the UnicastRemoteObject
import java.rmi.registry.LocateRegistry;    //!! To use the LocateRegistry
import java.rmi.registry.Registry; //!! To use the Registry



public class Server {
    public static void main(String[] args) {
        try {
        //!! Set Hostname Server using JavaProperty
        System.setProperty("java.rmi.server.hostname"," 127.0.0.1");
        System.out.println("The server is running");




        //!! Here we can define API or product objects
        //!! Creating Objects
        ProductImp p1 = new ProductImp ("Ak-47", "Assault-Rifle", 200.0);
        ProductImp p2 = new ProductImp ("M249", "Light-Machine Gun", 4087.0);
        ProductImp p3 = new ProductImp ("P90", "Sub Machine Gun", 2350.0);
        ProductImp p4 = new ProductImp ("P2000", "Semi-automatic Pistol", 560.47 );
        
        //!! Exporting Objects using UnicastRemoteObject class
        
        Product stub1 = (Product) UnicastRemoteObject.exportObject(p1, 0);
        Product stub2 = (Product) UnicastRemoteObject.exportObject(p2, 0);
        Product stub3 = (Product) UnicastRemoteObject.exportObject(p3, 0);
        Product stub4 = (Product) UnicastRemoteObject.exportObject(p4, 0);

        //!! Register the Exported in the RMI registry
        //!! Client will use the name  to get those objects

        //!! Get the registry to the object
        Registry registry = LocateRegistry.getRegistry("127.0.0.1", 9100);
        
        registry.bind("Assault", stub1);
        registry.bind("LMG", stub2);
        registry.bind("SMG", stub3);
        registry.bind("Semi Pistol", stub4);

        System.out.println("Exporting and Binding done...");

    } catch (Exception e) {
       System.out.println("Some server error ..." + e);
    }
 }    
}

我正在尝试学习RMI

我已经添加了java bin文件夹的环境变量路径 并添加了防火墙入站规则java.exe

我期望打印（导出和绑定完成...） 还预计使用cmd输入start rmiregistry 9100不会关闭

使用应用程序 TCPView 查看所有使用的端口并更改我的客户端和服务器端口
