ibatis中resultMap和resultClass(Mybatis的resultType)的区别

resultMap和resultClass指的是在 select查询中的返回数据类型

resultMap取值

一、resultMap必须和我们之前定义<resultMap id="accountMerchantDistribution"的Id相同

 <resultMap id="accountMerchantDistribution" class="com.sfbest.bean.AccountMerchantDistribution" >

    <result column="id" property="id" jdbcType="int" />

    <result column="merchant_number" property="merchantNumber" jdbcType="int" />

    <result column="province" property="province" jdbcType="int" />

    <result column="city" property="city" jdbcType="int" />

    <result column="county" property="county" jdbcType="int" />

    <result column="distribute_times" property="distributeTimes" jdbcType="int" />

    <result column="pay_cash" property="payCash" jdbcType="int" />

  </resultMap>

 <resultMap id="accountMerchantDistribution" class="com.sfbest.bean.AccountMerchantDistribution" >

  </resultMap> 重复使用占有优势

二、resultClass取值

1.resultClass="int"

2.resultClass="com.sfbest.product.bean.ProductPicture"

3.resultClass="string"

4.resultClass="long"

5.resultClass="java.util.HashMap"

三、parameterClass指的是select save update delete   SQL语句的where执行条件

parameterClass可以的取值

1、parameterClass="int"

2、parameterClass="map"     

3、parameterClass="com.sfbest.bean.AccountMerchantDistribution"
