java RMI
RMI入门1.定义接口
package com.test.rmi;
import java.rmi.Remote;
import java.rmi.RemoteException;
public interface RMITest extends Remote {
long getPerfectTime()throws RemoteException;
}
2.实现接口，定义服务类
package com.test.rmi;
import java.rmi.Naming;
import java.rmi.RemoteException;
import java.rmi.server.UnicastRemoteObject;
public class RMITestImp extends UnicastRemoteObject implements RMITest {
protected RMITestImp() throws RemoteException {
super();
}
public long getPerfectTime() throws RemoteException {
return System.currentTimeMillis();
}
public static void main(String[] args) {
if(System.getSecurityManager()==null){
System.out.println("security manager");
System.setSecurityManager(new SecurityManager());
}
try {//创建远程对象的一个或多个实例
RMITestImp rt =new RMITestImp();
System.out.println("hello");
Naming.rebind("Hello", rt);//把hello注册到RMI注册服务器上，命名为Hello
System.out.println("bind OK");
} catch (Exception e) {
}
}
}
3.定义客户端类
