Question

我在mongo存储库中有以下查询：

@Query("{ 'lastKnownLocation' : { $near : ?0}, 'username' : { $exists: true },
'lastActiveTime' : { $gte: ?1 }, 'id' : { $ne: ?2 }, 
$or: [ { 'hideAccountInPeopleNearby': false }, 
{ 'hideAccountInPeopleNearby': { $exists: false} } ] }")
List<Account> findTop6ByLastKnownLocationNearAndUsernameExistsAndLastActiveTimeBeforeAndId
NotAndHideAccountInPeopleNearbyFalse(Point lastKnownLocation, LocalDate lastActiveTime, 
String id);

它返回以下错误：

com.mongodb.MongoQueryException: Query failed with error code 2 and error message 'error

这里出了什么问题？如果我删除方法上方的@Query（并添加boolean exists参数），则会正确返回值。但是，我需要查询能够返回hideAccountInPeopleNearby为false或null的值。

Answer 1

原来解决方案只是将$near更改为$nearSphere

无法使用@Query
