我在 Mongo 中的文档结构是这样的:
My document structure in Mongo is like this :
db.user.find()
db.user.find()
{ "_id" : ObjectId("560fa46930a8e74be720009a"), "createdAt" : ISODate("2015-10-03T09:47:56.333Z"), "message" : "welcome", } { "_id" : ObjectId("560fa46930a8e723e720009a"), "createdAt" : ISODate("2015-10-03T09:48:25.048Z"), "message" : "thank you" }当我在 Mongo Shell 中使用以下查询在两个给定时间戳之间查找文档时,我得到了正确的结果:
When I use the below query in my Mongo Shell to find documents between two given timestamps, i get the right result :
db.user.find({createdAt:{$gte:ISODate("2015-10-03T09:40:25.048Z"),$lte:ISODate("2015-10-03T09:50:56.333Z")}})我在我的 REST 服务中使用 MongoRepository 和 Spring 来处理 Java 驱动程序.以下是用户存储库:
I am using MongoRepository with Spring in my REST service to work with the Java driver. Below is the user repository:
public interface UserRepository extends MongoRepository<User, String> { ArrayList<User> findbyCreatedAtBetween(Date d1, Date d2); }当我在我的服务中调用 make 以下调用时,它不返回任何结果userRepository.findbyCreatedAtBetween(2015-10-03T09:40:25.048Z, 2015-10-03T09:50:29.006Z)
When I call make the following call in my service, it does not return any result userRepository.findbyCreatedAtBetween(2015-10-03T09:40:25.048Z, 2015-10-03T09:50:29.006Z)
但是,当我将 d1 作为前一天给出时,它会返回结果:userRepository.findbyCreatedAtBetween(2015-10-02T09:40:25.048Z, 2015-10-03T09:50:29.006Z)
However it returns the result when I give d1 as previous day : userRepository.findbyCreatedAtBetween(2015-10-02T09:40:25.048Z, 2015-10-03T09:50:29.006Z)
有关如何解决此问题的任何想法?请帮忙!
Any ideas on how I can resolve this? Please help!
推荐答案细分下来,正在对 MongoDB 数据库执行带有关键字 Between 的查询,逻辑结果为 {"createdAt" : {"$gt" : d1, "$lt" : d2}} 所以你有可能没有得到包含 createdAt 日期的文档给定的日期范围即 d1 Breaking it down, the query with the keyword Between is being executed against the MongoDB database with the logical result {"createdAt" : {"$gt" : d1, "$lt" : d2}} so there is a chance that you are not getting the documents that have the createdAt date inclusive within the given date range i.e. d1 < createdAt < d2 since the given date range does not satisfy the criteria. For reference these are some of the interpretations on the query methods: 查询方法支持的关键字 作为一种解决方法,您可能需要使用 @Query 注释.我尚未对此进行测试,但您可能想尝试以下自定义查询实现示例: As a workaround, you may want to use the @Query annotation. I haven't tested this but you may want to try the following custom query implementation example: 如果以上方法对您不起作用,请创建一个自定义接口和您的实现类来执行自定义查询.例如,创建一个接口,其名称附加 Custom: If the above doesn't work for you, create a custom interface and your implementation class to execute the custom query. For example, create an interface with a name that appends Custom: 修改UserRepository,增加要扩展的UserRepositoryCustom接口: Modify the UserRepository and add the UserRepositoryCustom interface to be extended: 创建您的实现类来实现UserRepositoryCustom 接口中定义的方法. Create your implementation class to implement the methods defined in UserRepositoryCustom interface.
