一、项目情况：spring-boot+mongodb+dubbo。
二、问题：调用dubbo服务并使用spring-data-mongodb的gte，lte时间段比较查询，
@Reference(retries = 1) private FunctionService functionService; //dubbo服务
//mongodb gte、lte查询
Date beginOfToday = DateUtils.getBeginOfToday();
Date endOfToday = DateUtils.getEndOfToday();
Criteria criteria = Criteria.where(Function.FIELD_CREATED_TIME).gte(beginOfToday).lte(endOfToday);
List<Function> todayFunctionList= functionService.find(new Query(criteria));
报错信息如下：

三、本应用中使用gte，lte查询没问题
@Autowired private FunctionTagService functionTagService;//本应用的Service
//mongodb gte、lte查询 Date beginOfToday = DateUtils.getBeginOfToday(); Date endOfToday = DateUtils.getEndOfToday(); Criteria criteria = Criteria.where(FunctionType.FIELD_CREATED_TIME).gte(beginOfToday).lte(endOfToday); List<FunctionTag> tagList = functionTagService.find(new Query(criteria));
四、问题分析
先记录一下问题，猜想是dubbo在序列化gte、lte请求参数时的bug。有空研究....有大神知道的话烦请告知下，多谢。
