sqlMap的配置

 

<sqlMap id=”Product”>
<cacheModel id=”productCache” type=”LRU”>
<flushInterval hours=”24”/>
<property name=”size” value=”1000” />
</cacheModel>
<typeAlias alias=”product” type=”com.ibatis.example.Product” />
<parameterMap id=”productParam” class=”product”>
<parameter property=”id”/>
</parameterMap>
<resultMap id=”productResult” class=”product”>
<result property=”id” column=”PRD_ID”/>
<result property=”description” column=”PRD_DESCRIPTION”/>
</resultMap>
<select id=”getProduct” parameterMap=”productParam” resultMap=”productResult” cacheModel=”product-cache”>
select * from PRODUCT where PRD_ID = ?
</select>
</sqlMap>

 虽然框架为您做了很多工作，为了完成一个简单的查询操作，依然需要做很多。别担心，下面是一个简洁版本。

<sqlMap id=”Product”>
<select id=”getProduct” parameterClass=” com.ibatis.example.Product”
resultClass=”com.ibatis.example.Product”>
select
PRD_ID as id,
PRD_DESCRIPTION as description
from PRODUCT
where PRD_ID = #id#
</select>
</sqlMap>
