1.编写远程方法接口
import java.rmi.Remote;
import java.rmi.RemoteException;
public interface MyRemote extends Remote{
public String sayHello(int year) throws RemoteException;
}
2.编写实现类
import java.rmi.Naming;
import java.rmi.RemoteException;
import java.rmi.server.UnicastRemoteObject;
import com.XXX.RemoteInterface.MyRemote;
/*java version "1.7.0_80"
*Java(TM) SE Runtime Environment (build 1.7.0_80-b15)
*Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)
*远程服务实现
*/
@SuppressWarnings("serial")
public class MyRemoteImpl extends UnicastRemoteObject implements MyRemote{
public String sayHello(int year) throws RemoteException {
return "I invoking this Method names sayHello() in "+year;
}
//此处为空的构造方法
public MyRemoteImpl() throws RemoteException { }
public static void main(String[] args){
try {
MyRemote service = new MyRemoteImpl();
Naming.rebind("/MyRemote/RemoteHello", service);
} catch (Exception e) {
e.printStackTrace();
}
}
}
3.编写客户端调用方法
import java.rmi.Naming;
import com.XXX.RemoteInterface.MyRemote;
/*
* 调用远程服务
*/
public class MyRemoteClient {
public static void main(String[] args){
new MyRemoteClient().go();
}
public void go(){
try {
MyRemote service = (MyRemote)Naming.lookup("rmi://127.0.0.1/MyRemote/RemoteHello");
String s = service.sayHello(2018);
System.out.println(s);
} catch (Exception e) {
e.printStackTrace();
}
}
}
3.1 打开cmd . cd 定位到项目classes 目录运行 rmic com.XXX.Remote.MyRemoteImpl 生成 MyRemoteImpl_Stub.class3.2 cmd 里在 classes目录下 执行 rmiregistry命令
3.3 启动 MyRemoteImpl 的 main()方法;
3.4 启动MyRemoteClient 的 main()方法;
控制台打印:“I invoking this Method names sayHello() in 2018”
远程方法调用成功
