<!-- 模糊查询  -->    <select id="findPersons" parameterClass="com.tq365.vo.Person" resultMap="person_result">        select * from t_person        <dynamic prepend="where">            <isNotEmpty prepend="and" property="personname">                personname like '%$personname$%'            </isNotEmpty>            <!--此为精确查询,模糊查询写成like '%$value$%',#XX#,#将其在sql中表现为'XX'            <isNotEmpty prepend="and" property="personname">                (personname like #personname#)            </isNotEmpty>            -->            <!--             <isNotEmpty prepend="AND" property="address">               (address like #address#)             </isNotEmpty>             -->        </dynamic>    </select>
