package action;


import dao.AccountDAO;
import model.Account;

public class LoginAction{
    private Account account;
    private AccountDAO accountDao;

    
    public void setAccount(Account account)
    {
        this.account=account;
    }
    public Account getAccount ()
    {
        return account;
    }
    public void setAccountDao(AccountDAO accountDao)
    {
        this.accountDao = accountDao;
    }
    public AccountDAO getAccountDao()
    {
        return this.accountDao;
    }
    
    public String execute() 
    {
        System.out.print(accountDao.toString());
/报错         System.out.print([b]accountDao[/b].toString()+"name:"+account.getName()+"password:"+account.getPassword());
        if ([b]accountDao[/b].isValid(account.getName(),account.getPassword())==true) return "success";
        else return "fail";
    }
}

在AccountDAO中我自己实现的代码
public boolean isValid(final String name,final String password) {
        [b]Session session=getHibernateTemplate().getSessionFactory().openSession();[/b]
        Criteria tmp=session.createCriteria(Account.class);
        List result = tmp.add(Restrictions.eq("name", name))
                         .add(Restrictions.eq("password", password))
                         .list();
        if(result.size()>0) {
            return true;
        } else {
            return false;
        }    
    }
