Spring.net的初次使用(1)--关于Dao类

大家注意修改 其中的日志操作的代码 可以将其注释


我将其中一写代码贴出来 UserDao.cs

using System;
using System.Collections.Generic;
using System.Text;
using System.Collections;
using Ivan.Spring.Model;
using Spring.Data.NHibernate;
namespace Ivan.Spring.Dao
{
    IUserDao接口#region IUserDao接口
    /**//// <summary>
    /// IUserDao接口
    /// </summary>
    public interface IUserDao : IDao
    {
        IList GetAllUsers();
    }
    #endregion

    public class UserDao : DaoBase, IUserDao
    {
        public UserDao()
        {
            //
            // TODO: 在此处添加构造函数逻辑
            //
        }
        public override Type GetEntityType()
        {
            return typeof(User);
        }
        public IList GetAllUsers()
        {
            try
            {
                string query = String.Format("FROM User user ");
                return HibernateTemplate.Find(query);
                //return this.HibernateTemplate.FindByNamedQueryAndNamedParam("GetAllAdvicesList",null,null);
            }
            catch (Exception ex)
            {
                PrintErrLog("GetAllUsers Error!", ex);
                return null;


            }
            //return null;
        }
    }
}

IDao.cs

using System;
using System.Collections;
using System.Collections.Generic;
using System.Text;
using Ivan.Spring.Model;
using Spring.Data.NHibernate;

namespace Ivan.Spring.Dao
{
    /**//// <summary>
    /// 实体对象数据访问接口
    /// </summary>
    public interface IDao
    {

        // Methods
        bool DeleteObject(Entity entity);
        IList GetAllObjectsList();
        Type GetEntityType();
        //string GetTableHead();
        Entity Load(object ID);
        Entity SaveObject(Entity entity);
        bool UpdateObject(Entity entity);


    }
}
