一、項目情況：spring-boot+mongodb+dubbo。

二、問題：調用dubbo服務并使用spring-data-mongodb的gte，lte時間段比較查詢，

@Reference(retries = 1) private FunctionService functionService; //dubbo服務
//mongodb gte、lte查詢
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));

報錯信息如下：

?

三、本應用中使用gte，lte查詢沒問題

@Autowired private FunctionTagService functionTagService;//本應用的Service
//mongodb gte、lte查詢 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、問題分析

先記錄一下問題，猜想是dubbo在序列化gte、lte請求參數時的bug。有空研究....有大神知道的話煩請告知下，多謝。
