Mybatis传递多个参数

　　 <!--

使用HashMap传递多个参数

parameterType 可以是别名或完全限定名 ,map->java.util.Map,这两个都是可以的

-->

<selectid="selectBlogByMap"parameterType="map"resultType="Blog">

SELECT t.ID, t.title, t.content

FROM blog t

WHERE t.title = #{h_title}

AND t.content =#{h_content}

</select>

<!-- 使用JavaBean传递多个参数 -->

<selectid="selectBlogByBean"parameterType="Blog"resultType="Blog">

SELECT t.ID, t.title, t.content

FROM blog t

WHERE t.title = #{title}

AND t.content =#{content}

</select>
