RMI之HelloWorld尝试

时间:2022-06-18 01:37:22

服务器端代码如下:

IHello接口:

import java.rmi.Remote;
import java.rmi.RemoteException; public interface IHello extends Remote { /**
* @return return hellowold
* @throws java.rmi.RemoteException
*/
public String helloWorld() throws RemoteException; /**
* @param someBodyName
* @return say hello to somebody
* @throws java.rmi.RemoteException
*/
public String sayHelloToSomeBody(String someBodyName) throws RemoteException;
}

Hello实现:

import java.net.MalformedURLException;
import java.rmi.AlreadyBoundException;
import java.rmi.Naming;
import java.rmi.RemoteException;
import java.rmi.registry.LocateRegistry;
import java.rmi.server.UnicastRemoteObject; /**
* @ClassName: HelloImpl
* @Description: TODO
* @author: Dorothy
* @Date: 2014-12-21 00:00:13
*/
public class HelloImpl extends UnicastRemoteObject implements IHello {
/**
*
* @throws RemoteException
*/
public HelloImpl() throws RemoteException {
} /**
*
* @return return Hello World!
* @throws java.rmi.RemoteException
*/
public String helloWorld() throws RemoteException {
return "Hello World!";
} /**
*
* @param someBodyName
* @return say Hello to somebody
* @throws java.rmi.RemoteException
*/
public String sayHelloToSomeBody(String someBodyName) throws RemoteException {
return "Hello " + someBodyName + "!";
} public static void main(String args[]) { try { IHello rhello = new HelloImpl();
LocateRegistry.createRegistry(8888);
Naming.bind("rmi://localhost:8888/RHello",rhello); System.out.println(">>>>>INFO:Binding Successfully!");
} catch (RemoteException e) {
e.printStackTrace();
} catch (AlreadyBoundException e) {
e.printStackTrace();
} catch (MalformedURLException e) {
e.printStackTrace();
}
}
}

客户端代码如下:

import java.net.MalformedURLException;
import java.rmi.Naming;
import java.rmi.NotBoundException;
import java.rmi.RemoteException; /**
* @ClassName: HelloClient
* @Description: TODO
* @author: Dorothy
* @Date: 2014-12-21 00:06:08
*/
public class HelloClient {
public static void main(String args[]){
try {
IHello rhello =(IHello) Naming.lookup("rmi://localhost:8888/RHello");
System.out.println(rhello.helloWorld());
System.out.println(rhello.sayHelloToSomeBody("Dorothy"));
} catch (NotBoundException e) {
e.printStackTrace();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (RemoteException e) {
e.printStackTrace();
}
}
}

同时IHello接口定义,在客户端也要有。

在linux机器之间测试通过,windows和linux之间不成功,以后有时间再看为什么~
