Mybatisplus 使用二级缓存遇到的问题

使用mp的分页插件时，开启二级缓存，查询报错 Caused by: java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

### SQL: SELECt COUNT(*) FROM eam_ass_class s RIGHT JOIN eam_ass_class m ON s.pid = m.ass_cl_cde RIGHT JOIN (SELECt t.ass_cl_cde AS l_class, t.ass_cl_nm AS l_class_na FROM eam_ass_class t WHERe t.pid = '0' AND t.`status` = '1') l ON m.pid = l.l_class WHERe s.`status` = '1' AND m.`status` = '1'
### Cause: java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

猜测可能是查询到的数据数据总数没有找到对应接收实体，所以报错，暂时的解决办法是创建page对象时，声明不查询总数，第四个参数--false

Page page = new Page<>(pageNum, pageSize,0L,false);

至于使用分页插件并且查询总数时，如何使用二级缓存还没有找到方法，仅于此记录一下
