我创建了一个在iReport中成功运行的报告。在本报告中，我使用了两个参数：start_date和end_date，但是当它在JasperReports Server上运行时，会出现异常，其中（start_date和end_date）参数未在查询中设置，您可以看到以下异常：

例外情况如下：

The server has encountered an error. Please excuse the inconvenience.

我知道问题出在哪里，查询中cast()函数的问题，当我删除此报告时执行得很好，但是当我删除cast()函数时，引用 [B@65c9658f 来自d_time列

解决方案是我在sql查询中使用 convert 函数而不是cast函数。在转换函数中，我使用了utf8格式，现在它适用于我，使用utf8也可以与 cast 函数一起使用，你可以尝试。

您可以看到查询如下：

SELECT
request_for_vehicle_managament_details.date r_date,
replace(CONVERT(group_concat(concat(request_for_vehicle_managament_details.start_time," - ",
request_for_vehicle_managament_details.end_time)) USING utf8 ),',',' ') as d_time,
driver_master.first_name as name
FROM
request_for_vehicle_magament
INNER JOIN request_for_vehicle_managament_details ON request_for_vehicle_magament.pk = request_for_vehicle_managament_details.request_for_vehicle_magament_pk
INNER JOIN vehicle_master ON request_for_vehicle_managament_details.vehicle_master_pk = vehicle_master.pk
INNER JOIN driver_master ON vehicle_master.driver_master_pk = driver_master.pk
where  request_for_vehicle_magament.date_from >= $P{start_date} and  request_for_vehicle_magament.date_to <= $P{end_date}
group by request_for_vehicle_managament_details.date
