IBatis 简易框架搭建

1、练习框架

ibatis主要dll介绍

IBatisNet.Common.dll	由DataAccess和DataMapper组成的共享程序集
IBatisNet.Common.Logging.Log4Net.dll	Log4Net集成记录器，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接口的封装

2、SqlMapperCreater.cs 初始化Ibatis操作类

    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 数据库访问层

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)
        {

            tb.COL_1 = ;
            list.Add(tb);
        }
    }
}

4、IBatisEntity

1、EntityBase.cs 实体基类

namespace IBatisEntity
{
    /// <summary>
    /// 实体基类
    /// </summary>
    [Serializable]
    public class EntityBase
    {
        // Fields
        protected EntityBase OldValue;

        protected EntityStateEnum _entityState = EntityStateEnum.Unchanged;
        /// <summary>
        /// 实体的数据版本,默认为未改变
        /// </summary>
        public EntityStateEnum EntityState
        {
            get { return _entityState; }
            set { _entityState = value; }
        }

        /// <summary>
        /// 默认构造函数
        /// </summary>
        protected EntityBase()
        {

        }

        /// <summary>
        /// 实现克隆接口
        /// </summary>
        /// <returns></returns>
        public virtual object Clone()
        {
            MemoryStream serializationStream = new MemoryStream();
            BinaryFormatter formatter = new BinaryFormatter();
            formatter.Serialize(serializationStream, this);
            serializationStream.Position = ;
            return formatter.Deserialize(serializationStream);
        }

        /// <summary>
        /// 在实体与数据表做相互转换时,制定表的列名称模式
        /// </summary>
        public enum ColumnNameEnum
        {
            /// <summary>
            /// 数据库对应列名称
            /// </summary>
            DBName = ,
            /// <summary>
            /// 实体对应字段名称
            /// </summary>
            PropertyName =
        }
    }

    /// <summary>
    /// 实体版本枚举
    /// </summary>
    public enum EntityStateEnum
    {
        /// <summary>
        /// 新增
        /// </summary>
        Added = ,
        /// <summary>
        /// 被修改
        /// </summary>
        Modified = ,
        /// <summary>
        /// 被删除
        /// </summary>
        Deleted = ,
        /// <summary>
        /// 未修改
        /// </summary>
        Unchanged = ,
        /// <summary>
        /// 新增的但是未加入任何table中
        /// </summary>
        Detached =
    }
}

2、TableEntity.cs 实体类

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界面层访问

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 = -, COL_2 = -, COL_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 =  });

            a = tableAccess.SelectWithRowDelegate(new TableEntity() { ID =  });
            MessageBox.Show(a.Count.ToString());

            DataTable dt = tableAccess.GetDataTable(new TableEntity() { ID =  });
        }
    }
}

6、xml文件配置

1、providers.config 提供了一些支持的数据库版本信息

  <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>

3、DataBase.config 数据库链接字符串

<?xml version="1.0" encoding="utf-8" ?>
<settings>

    <!--  定义4个属性，在sqlMap.config中调用 -->
    <add key="DatabaseName" value="DatabaseName"/>
    <add key="DataSource" value="DataSource"/>
    <add key="UserID" value="UserID"/>
    <add key="Password" value="Password"/>

</settings>

4、TableEntity.xml 具体操作的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_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">
      <!--     按照规范序列应该为[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>
