我的項目是客戶機/服務器的客戶端發送對象到服務器，服務器響應，所有通過RMIRMI客戶UnmarshalException
客戶端項目
//接口
public interface RMI_INTERFACE extends Remote
{
public int Add(Employee e) throws RemoteException;
}
//我需要發送的類
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;
}
}
//客戶端
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());
}
}
}
//服務器項目
//接口 公共接口RMI_INTERFACE擴展遠程 {
public int Add(Employee e) throws RemoteException;
}
//類，我將它發送和接收它 公共類員工實現Serializable { int ID;
String Name;
int Salary;
public Employee(int id,String name,int salary)
{
ID=id;
Name =name;
Salary=salary;
}
}
//類來保存所有接收到的對象 公共類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;
}
}
//服務器 公共類RMI_SERVER擴展了UnicastRemoteObject實現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();
}
}
當我運行客戶端出現此錯誤：java.rmi.UnmarshalException：無法識別的方法哈希：方法沒有t由遠程對象支持
