myhabits where in foreach

myhabits传入参数：类，其中类中包含字符串数组String[]

当查询where in String[]时

<select id="selectData" parameterType="DataDay"<!-- 类名 -->
        resultMap="DataResult">
       select * from
        data_day
        <where>
            <if test="selectStringName != null  and selectStringName!= ‘‘ and selectStringName.length!=0 ">
                and selectName in
                <foreach collection="selectStringName" <!-- 注意此处要写这个字符串数组的名称 -->

                    item="selectStringName"

 open="(" separator="," close=")"> #{selectStringName} </foreach>
            </if>
        </where>
    </select>

如果写成 collecton=“array”，会报错There is no getter for property named ‘array‘ in ‘class ...
