在Spring中使用RMI公开多个对象

public interface MyRemoteService extends Remote {
    String hello(String name) throws RemoteException;
    int add(int a, int b) throws RemoteException;
}

public class MyRemoteServiceImpl extends UnicastRemoteObject implements MyRemoteService {
    public MyRemoteServiceImpl() throws RemoteException {
        super();
    }

    @Override
    public String hello(String name) throws RemoteException {
        return "Hello, " + name + "!";
    }

    @Override
    public int add(int a, int b) throws RemoteException {
        return a + b;
    }
}

<bean id="myRemoteService" class="com.example.MyRemoteServiceImpl" />

<bean class="org.springframework.remoting.rmi.RmiServiceExporter">
   <property name="serviceName" value="MyRemoteService" />
   <property name="service" ref="myRemoteService" />
   <property name="serviceInterface" value="com.example.MyRemoteService" />
   <property name="registryPort" value="1099" />
</bean>

MyRemoteService service = (MyRemoteService) Naming.lookup("rmi://localhost:1099/MyRemoteService");
String result = service.hello("World");
System.out.println(result);
