使用JPA分页查询时，每页10条数据，当总数据不超过10条时，查询没问题，当总数据超过10条时，就报错了，错误信息：

java代码：
controller层：

    public Page<ProjectOrder> page(@RequestBody PagingQueryParams<ProjectOrder> params) {
        params.fetch(ProjectOrder_.CUSTOMER);
        params.fetch(String.format("%s.%s", ProjectOrder_.PROJECT, Project_.PROJECT_CATEGORY));
        params.fetch(ProjectOrder_.ACCOUNT);
        return wechatProjectOrderService.page(params);
    }

service：

    @Override
    @Transactional(readOnly = true)
    public Page<ProjectOrder> page(PagingQueryParams<ProjectOrder> params) {
        return projectOrderRepository.findAll(params);
    }

gradle依赖：

implementation 'com.dameng:Dm8JdbcDriver18'
implementation 'com.dameng:DmDialect-for-hibernate5.3'
implementation 'com.alibaba:druid'

达梦驱动和方言版本：

dependency("com.dameng:Dm8JdbcDriver18:8.1.1.49")
dependency("com.dameng:DmDialect-for-hibernate5.3:8.1.1.49")

hibernate版本：

id 'org.hibernate.orm' version '6.1.7.Final'

很急，之前数据少没发现这个问题，现在数据多了就出现这个问题了，望各位大神解答一下
