还有使用JAVA的RMI实现客户端和服务器端通信的方法吗？

packagecom.rmi;
importlombok.AllArgsConstructor;
importlombok.Data;
importjava.io.Serializable;
@Data@AllArgsConstructorpublicclassUserimplementsSerializable {
privatestaticfinallongserialVersionUID=2159427410483687648L;
privateIntegerid;
privateStringusername;
}

packagecom.rmi;
importjava.rmi.Remote;
importjava.rmi.RemoteException;
publicinterfaceUserServiceextendsRemote {
UserselectUserById(IntegeruserId) throwsRemoteException;
}

packagecom.rmi;
importjava.rmi.RemoteException;
importjava.rmi.server.UnicastRemoteObject;
publicclassUserServiceImplextendsUnicastRemoteObjectimplementsUserService {
publicUserServiceImpl() throwsRemoteException {
    }
@OverridepublicUserselectUserById(IntegeruserId) throwsRemoteException {
System.out.println("用户管理服务接收到客户端请求，请求参数 userId = "+userId);
// 模拟假数据返回returnnewUser(userId, "张三");
    }
}

packagecom.rmi;
importjava.net.MalformedURLException;
importjava.rmi.AlreadyBoundException;
importjava.rmi.Naming;
importjava.rmi.RemoteException;
importjava.rmi.registry.LocateRegistry;
publicclassPublish {
publicstaticvoidmain(String[] args) throwsRemoteException {
UserServiceuserService=newUserServiceImpl();
try {
// 对外暴露的服务端口LocateRegistry.createRegistry(8888);
// 对外暴露的服务地址Naming.bind("rmi://localhost:8888/userService", userService);
System.out.println("服务发布成功！");
        } catch (AlreadyBoundExceptione) {
e.printStackTrace();
        } catch (MalformedURLExceptione) {
e.printStackTrace();
        }
    }
}

packagecom.rmi;
importjava.net.MalformedURLException;
importjava.rmi.Naming;
importjava.rmi.NotBoundException;
importjava.rmi.RemoteException;
publicclassUserController {
publicstaticvoidmain(String[] args) {
try {
UserServiceuserService= (UserService) Naming.lookup("rmi://localhost:8888/userService");
Useruser=userService.selectUserById(1);
System.out.println("远程服务调用成功，返回值信息为："+user);
        } catch (NotBoundExceptione) {
e.printStackTrace();
        } catch (MalformedURLExceptione) {
e.printStackTrace();
        } catch (RemoteExceptione) {
e.printStackTrace();
        }
    }
}
