<?xml version="1.0" encoding="utf-8" ?>
<sqlMap namespace="Ibatis" xmlns="http://ibatis.apache.org/mapping" xmlns:xls="http://www.w3.org/2001/XMLSchema-instance">
  <resultMaps>
    <resultMap id="blogcontent" Class="StudyDemo.Model.Blog">
      <result property="Id" column="Id" />
      <result property="No" column="TestNo"/>
      <result property="Title" column="TestTitle"/>

    </resultMap>
  </resultMaps>
  <statements>
    <sql id="order">
      order by Id desc
    </sql>
    <select id="selectAllBlog" resultMap="blogcontent">
      select * from blogcontent
      <inclued refid="order"/>
    </select>
    <select id="selectAllBlogOrderbyNodesc" resultMap="blogcontent" parameterClass="StudyDemo.Model.Blog" extends="selectAllBlog">
      where TestNo =#No#
      <include refid="order"/>
    </select>
    <insert id="InsertBlogContent" resultMap="blogcontent">
      Insert Into BlogContent (TestNo,TestTitle,TestContent) values(#No#,#Title#,#Content#)
      <selectKey  type="post" resultClass="int" property="Id">
        select CAST(@@IDENTITY as int) as Id
      </selectKey >
    </insert>
    <update id="UpdateBlogContent" resultMap="blogcontent">
      update blogcontent set testNo=#No#,TestTitle=#Title#,TestContent=#Content# where Id=#Id#
    </update>
    <delete id="deleteBlogContent" resultMap="blogcontent">
      delete from blogcontent where id=#Id#
    </delete>
  </statements>
</sqlMap>

以上是映射配置文件

 下面是SqlMap.config 文件

<?xml version="1.0" encoding="utf-8"?>
<sqlMapConfig xmlns="http://ibatis.apache.org/dataMapper" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <properties resource="../../config/properties.config"/>
  <settings>
    <setting useStatementNamespaces="false"/>
  </settings>
  <providers  resource="providers.config"/>
  <database>
    <provider name="sqlServer2008"/>
    <dataSource name="test" connectionString="server=GSHC-LIWC8;uid=sa; pwd=111111;database=Test"/>
  </database>
  <sqlMaps>
    <sqlMap  resource="../../config/test/BlogContent.xml"/>
  </sqlMaps>
</sqlMapConfig>
