远程控制台java环境设置方法 远程调用java

1，实现Remote 接口
public interface ExecuteTaskI extends Remote{
  
  long getCurrentTime() throws RemoteException;}

2，
public class ExecuteTask extends UnicastRemoteObject implements ExecuteTaskI {
 /**
   * 序列化编号
   */
  private static final long serialVersionUID = 5106682387234335126L; public ExecuteTask() throws RemoteException {
   super();
  } @Override
  public long getCurrentTime() throws RemoteException {
   System.out.println("successfully");
   return System.currentTimeMillis();
  }
  
  
 }3，
public static void main(String[] args) throws AlreadyBoundException {
   //System.setSecurityManager(new RMISecurityManager());
   try {
    ExecuteTask exec = new ExecuteTask();
    LocateRegistry.createRegistry(8889);
    Naming.rebind("//10.30.12.141:8889/Detop", exec);
    
   } catch (RemoteException e) {
    e.printStackTrace();
   } catch (MalformedURLException e) {
    e.printStackTrace();
   }
  }4，
public static void main(String[] args) {
   try {
    String url = "//10.30.12.141:8889/Detop";
    ExecuteTaskI RmiObject = (ExecuteTaskI) Naming.lookup(url);
    System.out.println("获取当前时间 :" + RmiObject.getCurrentTime());
   } catch (RemoteException rex) {
    System.out.println("Error in lookup: " + rex.toString());
   } catch (java.net.MalformedURLException me) {
    System.out.println("Malformed URL: " + me.toString());
   } catch (java.rmi.NotBoundException ne) {
    System.out.println("NotBound: " + ne.toString());
   } }
