Question

我想应用多个条件查询运算符来根据时间戳获取数据

public List<Notification> getNotificationByTime(long notificationTime) {

    return mongoTemplate.find(new Query(Criteria.where("createdAt").lte(notificationTime).
        orOperator(Criteria.where("updatedAt")
            .lte(notificationTime)).orOperator(Criteria.where("failureTime").gt(3))
            ), Notification.class);
  }

例外

Answer 1

public List<Notification> getNotificationByTime(long notificationTime) {

    return mongoTemplate.find(new Query(Criteria.where("createdAt").lte(notificationTime),
        Criteria.where("updatedAt").lte(notificationTime)),Criteria.where("failureTime").gt(3)
            ), Notification.class);
  }

这必须工作。括号内的所有内容都会被删除：）

Answer 2

public List<Notification> getNotificationByTime(long notificationTime) {

return mongoTemplate.find(new Query(new Criteria().andOperator(
    new Criteria().orOperator(
      Criteria.where("createdAt").lte(notificationTime),
      Criteria.where("updatedAt").lte(notificationTime)
    ),
    Criteria.where("failureTime").gt(3)), 
    Notification.class);
}

认为这必须很好。

如何在MongoTemplate中使用多个orOperator
