<!-- 返回HashMap结果 类型-->  
    <!-- 如果想返回JavaBean,只需将resultType设置为JavaBean的别名或全限定名 -->  
    <!-- TypeAliasRegistry类初始化时注册了一些常用的别名，如果忘记了别名可以在这里面查看 -->  
    <select id="selectBlogRetHashMap" parameterType="int" resultType="map">  
        SELECT id AS "id", title AS "title", content AS "content" FROM Blog WHERE id = #{id}  
    </select>
