IBatis 簡易框架搭建
一、練習框架
ibatis主要dll介紹sql
| 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框架數據庫 |
二、IBatisDao
一、DaoBase.cs Ibatis接口的封裝

} #endregion } }
二、SqlMapperCreater.cs 初始化Ibatis操做類
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; } } }
三、IBatisDataAccess
一、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); } } }
四、IBatisEntity
一、EntityBase.cs 實體基類
namespace IBatisEntity { /// <summary> /// 實體基類 /// </summary> [Serializable] public class EntityBase { // Fields protected EntityBase OldValue; protected EntityStateEnum _entityState = EntityStateEnum.Unchanged; /// <summary> /// 實體的數據版本,默認爲未改變 /// </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> /// 在實體與數據表作相互轉換時,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> /// 新增的可是未加入任何table中 /// </summary> Detached = 5 } }
二、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; } } }
五、IBatisApp界面層訪問
一、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 }); } } }
六、xml文件配置
一、providers.config 提供了一些支持的數據庫版本信息

二、sqlMap.config sqlmap的基本信息
<?xml version="1.0" encoding="utf-8"?> <sqlMapConfig xmlns="http://ibatis.apache.org/dataMapper" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" > <!-- Rem : If used via a DataAccess context, properties tag will be ignored --> <!--數據庫配置參數 屬性--> <properties resource="Config//DataBase.config"/> <settings> <!--setting useStatementNamespaces="false"/--> <setting cacheModelsEnabled="true"/> <setting validateSqlMap="false"/> </settings> <providers resource="config//providers.config"/> <database> <provider name="oracleClient2.0"/> <dataSource name="${DatabaseName}" connectionString="Data Source=${DataSource}; User ID=${UserID}; Password=${Password}"/> </database> <alias> <typeAlias alias="ArrayList" type="System.Collections.ArrayList,mscorlib"/> </alias> <sqlMaps> <!--===== sqlMap文件=======--> <sqlMap resource="config//TableEntity.xml"/> </sqlMaps> </sqlMapConfig>
三、DataBase.config 數據庫連接字符串
<?xml version="1.0" encoding="utf-8" ?> <settings> <!-- 定義4個屬性，在sqlMap.config中調用 --> <add key="DatabaseName" value="DatabaseName"/> <add key="DataSource" value="DataSource"/> <add key="UserID" value="UserID"/> <add key="Password" value="Password"/> </settings>
四、TableEntity.xml 具體操做的xml
<?xml version="1.0" encoding="UTF-8" ?> <sqlMap namespace="TableEntity" xmlns="http://ibatis.apache.org/mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <alias> <typeAlias alias="TableEntity" type="IBatisEntity.TableEntity" /> <!--<typeAlias alias="TableEntity.Key" type="long" />--> </alias> <resultMaps> <resultMap id="TableEntity_AllColumns" class="TableEntity"> <result property="ID" column="ID" /> <result property="COL_1" column="COL_1" /> <result property="COL_2" column="COL_2" /> <result property="COL_3" column="COL_3" /> <result property="REFRESH_DATE" column="REFRESH_DATE" /> </resultMap> </resultMaps> <parameterMaps> <parameterMap id="TableEntityParam" class="HashTable"> <parameter property="ID" column="ID" direction="Input" /> <parameter property="COL_1" column="COL_1" direction="Input" /> <parameter property="COL_2" column="COL_2" direction="Input" /> <parameter property="COL_3" column="COL_3" direction="Input" /> <parameter property="REFRESH_DATE" column="REFRESH_DATE" direction="Input" /> </parameterMap> </parameterMaps> <statements> <insert id="TableEntity_Insert" parameterClass="TableEntity" resultClass="int"> <!-- 按照規範序列應該爲[TABLE]_S --> <selectKey property="ID" type="pre" resultClass="long"> select pto_kit_s.nextval as value from dual </selectKey> INSERT INTO A_TEST_1 (ID, COL_1, COL_2, COL_3) VALUES (#ID#, #COL_1#, #COL_2#, #COL_3#) </insert> <select id="TableEntity_Select" parameterClass="TableEntity" resultMap="TableEntity_AllColumns"> select id, col_1, col_2, col_3, refresh_date from scp.A_TEST_1 t where id=#ID# </select> <select id="TableEntity_Select_Datatable" parameterClass="TableEntity"> select id, col_1, col_2, col_3, refresh_date from A_TEST_1 t where id=#ID# </select> </statements> </sqlMap>
