早上在摸索QueryDSL,MongoDB和Java8提供的时间类的结合使用时，突然出现了这个问题。
根据错误日志可以看出这是找不到LocalDateTime类型的bson编解码器(MongoDB使用BSON作为存储结构)而抛出的异常。
下面这个解决方案可以最快捷地绕过这个坑。

解决方案
这个问题是在使用between条件查询时出现的：qe.time.between(time,time.plusDays(1l))
将between拆分成before和after组合的条件即可正常使用:qe.time.after(time).and(qe.time.before(time.plusDays(1l))
