<select id="queryList" resultType="com.performancetest.modules.ptest.entity.StressTestSlaveEntity" >

        <where>
            <if test="slaveName != null and slaveName.trim() != ''">
                slave_name like concat('%', #{slaveName}, '%')
            </if>
            <if test="status != null">
                `status` = #{status}
            </if>
            <if test="slaveIds != null and slaveIds.isEmpty()==false">
                slave_id in
　　　　　　　　　　

--                 collection為要迭代的變量，item為單個元素

<foreach item="slaveId" collection="slaveIds" open="(" separator="," close=")"> #{slaveId} </foreach> </if> </select>
