我尝试使用RMI,这是服务器端代码。一开始它可以正常工作而没有任何异常,但是现在已经出现了三次错误,每当我尝试运行下面的代码时,都会得到一些错误。
代码如下:
import java.rmi.server.UnicastRemoteObject;
/**
* Created by elyas on 12/11/14 AD.
*/
public class LogicImplement extends UnicastRemoteObject implements Logic
{
public LogicImplement() throws Exception
{
java.rmi.registry.LocateRegistry.createRegistry(6060);
java.rmi.Naming.rebind("Object1",this);
}
@Override
public int sum(int a, int b) throws Exception
{
int result = a + b;
System.out.println("ana sum executed");
return result;
}
public static void main(String[] args)
{
try
{
LogicImplement logicImplement = new LogicImplement();
} catch (Exception e)
{
e.printStackTrace();
}
}
}
错误信息如下:我试图将Object1更改为例如Object2,但仍然会出现错误,我还更改了端口号...解决方案是什么?
