查看控制台的时候发现查询条件in后面空了

再看mybatis的判空条件，只有!=null，还需要再加一个and purchaseIdList.size() > 0

<if test="purchaseIdList != null and purchaseIdList.size() > 0"> and purchase_id in 
                <foreach item="purchaseId" collection="purchaseIdList" open="(" separator="," close=")" index="index">
                    #{purchaseId}
                </foreach>
            </if>
