Question

我的项目是客户端/服务器，客户端将对象发送到服务器并且服务器响应，所有这些都是由RMI

客户项目

//界面

public interface RMI_INTERFACE extends Remote
{

public int Add(Employee e) throws RemoteException;
}

//我需要发送它的类

public class Employee implements Serializable
{
int ID;

String Name;

int Salary;

public Employee(int id,String name,int salary) 
{
    ID=id;

    Name =name;

    Salary=salary;
}


}

//客户端

public class RMI_CLIENT 
{

public RMI_CLIENT() 
{

}

public static void main(String[] args) {    
    try {


         String name = "RMI_INTERFACE";
        Registry registry = LocateRegistry.getRegistry("localhost",5000);
        RMI_INTERFACE si = (RMI_INTERFACE) registry.lookup(name);

        int ii;

        for (Integer i=0 ;i<10;i++)
        {
            Employee e= new Employee(i,  "employee"+i.toString() , i*1000+100);

            ii=si.Add(e);
            System.out.println(ii);

        }

       // int pi = si.Get_Salary(s);


    } catch (Exception e) {
        System.err.println(e.getCause());
    }
}
}

//服务器项目

//界面公共接口RMI_INTERFACE扩展了Remote {

public int Add(Employee e) throws RemoteException;
}

//我将发送并接收它的类公共类Employee实现Serializable { int ID;

String Name;

int Salary;

public Employee(int id,String name,int salary) 
{
    ID=id;

    Name =name;

    Salary=salary;
}


}

//用于保存所有收到的对象的类公共课Maneger {

static Employee [] employee_arr = new Employee[10];

static int i=0;

Maneger (Employee e)
{
    employee_arr[i]=e;

    i++;

}

public int Get_Index ()
{
    return i;
}
}

//服务器公共类RMI_SERVER扩展UnicastRemoteObject实现RMI_INTERFACE {

RMI_SERVER() throws RemoteException 
{
      super();
}

/**
 * @param args the command line arguments
 */
public static void main(String[] args) {
    try {
        // TODO code application logic here         

        String name = "RMI_INTERFACE";
        RMI_INTERFACE si = new RMI_SERVER();        
        Registry registry = LocateRegistry.createRegistry( 5000 );
         registry.rebind(name, new RMI_SERVER() );
        System.out.println("Server is running ...");




    } 
    catch (Exception e) {
        System.err.println("ComputeEngine exception:");
    }



}

@Override
public int Add(Employee e) throws RemoteException {

    Maneger m =new Maneger(e);

    return m.Get_Index();

}


}

当我运行客户端时出现此错误：java.rmi.UnmarshalException：无法识别的方法哈希：远程对象不支持的方法

Answer 1

您已更改远程对象或远程接口，但尚未重新编译并重新部署所有受影响的.class文件。
