Castle.ActiveRecord 使用 存储过程 返回实体类

 

 
这几日就在研究这个问题
寻遍网上,也没找到个解决方法只有 在NHibernate里执行存储过程
里面操作NHibernate的一点方法
于是动手写成了以下这个类

当然,只能保证测试可以通过,可能还有很多问题,要一个一个解决

namespace ChAlumna.CastleExt
{
    using Castle.ActiveRecord;
    using Castle.ActiveRecord.Framework;
    using Castle.ActiveRecord.Framework.Config;
    using System;

    using NHibernate;
    using NHibernate.Cfg;
    using NHibernate.Expression;
    using System.Collections.Generic;
    using System.Text;
    using System.Data;
    public class Execute
    {
        /**//// <summary>
        /// 使用存储过程填充实体类,邹健,2008 1 24
        /// </summary>
        /// <typeparam name="T">实体类</typeparam>
        /// <param name="spname">存储过程名</param>
        /// <param name="idict">参数字典</param>
        /// <returns>一个实体类Ilist</returns>
        public static IList<T> GetList<T>(string spname, IDictionary<String, Object> idict) {
            Type type = typeof(T);
            //Chsword.DoDataBase d = new Chsword.DoDataBase();
            StringBuilder sp = new StringBuilder();
            foreach (string key in idict.Keys) {
                sp.AppendFormat(":{0},", key);
            }
            if (sp.Length != 0)
                sp.Length--;
            string map = String.Format(@"<sql-query name='{0}'>
<return class='{1}'/>
exec {0} {2}
</sql-query>",
             spname,
             type.Name,
             sp.ToString()
             );

            Execute.CreateQueryMapping(type, map);//创建一个SQL-Query
            ISessionFactoryHolder holder = ActiveRecordMediator.GetSessionFactoryHolder();

            ISession session = holder.CreateSession(type);
            IQuery query = session.GetNamedQuery(spname);

            foreach (string key in idict.Keys) {
                query = query.SetParameter(key, idict[key]);
            }
            return query.List<T>();
        }
        /**//// <summary>
        /// 创建一个Sql-Query
        /// </summary>
        /// <param name="type">类型,做为Key</param>
        /// <param name="xml">Sql-Query结点</param>
        public static void CreateQueryMapping(Type type, string xml) {
            ISessionFactoryHolder holder = ActiveRecordMediator.GetSessionFactoryHolder();
            Configuration config = holder.GetConfiguration(holder.GetRootType(type));

            //    xml = ;
            config.AddXmlString(
                string.Format("<hibernate-mapping xmlns='{0}' assembly='{1}' namespace='{2}'>{3}</hibernate-mapping>",
                             Configuration.MappingSchemaXMLNS,
                             type.Assembly.FullName,
                             type.Namespace,//命名空间
                             xml//内容即<Sql-Query />
                        )
                    );
            //return config.NamedSQLQueries.Count.ToString();
        }
}
}

 

使用方法如下

            IDictionary<string,object> p=new Dictionary<string,Object>();//参数
            p.Add("userid", 10000);//参一
            p.Add("id", 17002);//参二
            p.Add("groupid", 51);//参三
            PropertyBag.Add("list",
                ChAlumna.CastleExt.Execute.GetList<LogToAccount>(//执行
                "Note_Select", p
                ));
PropertyBag.Add是MonoRail里的一个系统字典,这里测试很正常

但是,有以下不中足(我想到的)

参数还不能实现out
不能用Many One来关联类,只能按存储过程中的字段来建一个新类,或将原实体类扩展
困了,想不出来了,有兴趣的同学自己试试吧
