生活随笔
收集整理的這篇文章主要介紹了
IBatis 简易框架搭建
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
1、練習框架
?ibatis主要dll介紹
| IBatisNet.Common.dll | 由DataAccess和DataMapper組成的共享程序集 |
| IBatisNet.Common.Logging.Log4Net.dll | Log4Net集成記錄器，和Log4Net配合使用 |
| IBatisNet.DataMapper.dll | DataMapper主要框架 |
| IBatisNet.DataAccess.dll | DataAccess框架 |
2、IBatisDao?
1、DaoBase.cs Ibatis接口的封裝

object paramObject, Action<object, object, IList<TableEntity>> action){return SqlMap.QueryWithRowDelegate<TableEntity>(tag, paramObject, new RowDelegate<TableEntity>(action));}#endregion} }2、SqlMapperCreater.cs 初始化Ibatis操作類
public class SqlMapperCreater{protected static ISqlMapper m_sqlMap = null;public static ISqlMapper SqlMap{get{if (m_sqlMap == null){string fileName = "Config\\sqlMap.config";DomSqlMapBuilder builder = new DomSqlMapBuilder();m_sqlMap = builder.Configure(fileName);}return m_sqlMap;}}}3、IBatisDataAccess?
1、TableAccess.cs 數據庫訪問層
namespace IBatisDataAccess {public class TableAccess : DaoBase<TableEntity>{public object Insert(TableEntity obj){return base.Insert("TableEntity_Insert", obj);}public IList<TableEntity> Select(TableEntity obj){return base.Select("TableEntity_Select", obj);}public IList<TableEntity> SelectWithRowDelegate(TableEntity obj){return base.QueryWithRowDelegate("TableEntity_Select", obj, new Action<object, object, IList<TableEntity>>(RowDelegate));}public DataTable GetDataTable(TableEntity obj){return base.GetDataTable("TableEntity_Select_Datatable", obj);}public void RowDelegate(object obj, object parameterObject, IList<TableEntity> list){TableEntity tb = obj as TableEntity;tb.COL_1 = 77;list.Add(tb);}} }4、IBatisEntity
1、EntityBase.cs 實體基類
namespace IBatisEntity {/// <summary>/// 實體基類/// </summary>[Serializable]public class EntityBase{// Fieldsprotected EntityBase OldValue;protected EntityStateEnum _entityState = EntityStateEnum.Unchanged;/// <summary>/// 實體的數據版本,默認為未改變/// </summary>public EntityStateEnum EntityState{get { return _entityState; }set { _entityState = value; }}/// <summary>/// 默認構造函數/// </summary>protected EntityBase(){}/// <summary>/// 實現克隆接口/// </summary>/// <returns></returns>public virtual object Clone(){MemoryStream serializationStream = new MemoryStream();BinaryFormatter formatter = new BinaryFormatter();formatter.Serialize(serializationStream, this);serializationStream.Position = 0;return formatter.Deserialize(serializationStream);}/// <summary>/// 在實體與數據表做相互轉換時,制定表的列名稱模式/// </summary>public enum ColumnNameEnum{/// <summary>/// 數據庫對應列名稱/// </summary>DBName = 1,/// <summary>/// 實體對應字段名稱/// </summary>PropertyName = 2}}/// <summary>/// 實體版本枚舉/// </summary>public enum EntityStateEnum{/// <summary>/// 新增/// </summary>Added = 1,/// <summary>/// 被修改/// </summary>Modified = 2,/// <summary>/// 被刪除/// </summary>Deleted = 3,/// <summary>/// 未修改/// </summary>Unchanged = 4,/// <summary>/// 新增的但是未加入任何table中/// </summary>Detached = 5} }2、TableEntity.cs 實體類
namespace IBatisEntity {[Serializable]public class TableEntity : EntityBase{public long ID { get; set; }public int COL_1 { get; set; }public int COL_2 { get; set; }public int COL_3 { get; set; }public DateTime REFRESH_DATE { get; set; }} }5、IBatisApp界面層訪問
1、Form1.cs
namespace IBatisApp {public partial class Form1 : Form{public Form1(){InitializeComponent();}private void button1_Click(object sender, EventArgs e){TableAccess tableAccess = new TableAccess();object a = tableAccess.Insert(new TableEntity() { COL_1 = -1, COL_2 = -2, COL_3 = -3, REFRESH_DATE = DateTime.Now });MessageBox.Show(a.ToString());}private void button2_Click(object sender, EventArgs e){TableAccess tableAccess = new TableAccess();IList<TableEntity> a = tableAccess.Select(new TableEntity() { ID = 66 });a = tableAccess.SelectWithRowDelegate(new TableEntity() { ID = 66 });MessageBox.Show(a.Count.ToString());DataTable dt = tableAccess.GetDataTable(new TableEntity() { ID = 66 });}} }6、xml文件配置
1、providers.config 提供了一些支持的數據庫版本信息
