PageHelper+mybatis+阿里云，count(0)报错

渺万里层云 2017-03-02 06:01:09

最近用了springboot+mybatis+阿里云，分页用了插件PageHelper，但出现一个问题
PageHelper.startPage((int pageNum, int pageSize) {
return startPage(pageNum, pageSize, true);
}

代码里设置：PageHelper.startPage(page.getPageNum(), page.getPageSize());

page.getPageNum()初始值=1，page.getPageSize()初始值=10。
执行如下查询：
orderList = cyOrderInfoService.queryCyOrderInfoList(cyOrder);
错误：SELECT count(0) FROM (SELECT DISTINCT info.order_id orderId, info.user_id userId FROM newcyerp_cy_order_info info WHERE info.order_id = ?) table_count
改成count（1）就没问题：SELECT count(0) FROM (SELECT DISTINCT info.order_id orderId, info.user_id userId FROM newcyerp_cy_order_info info WHERE info.order_id = ?) table_count
这可可能哪里出了问题呢？
报错console输出：
