SpringData MongoDB和条件查询出错，其中相同的字段出现两次

标签： mongodb criteria spring-data-mongodb

我有以下查询来从集合中获取文档：

public List<Event> findSubEventsBetweenDates(Event parentEvent, LocalDate lowerDate, LocalDate upperDate) {

    return mongo.find(query(
            where("parentEvent").is(parentEvent)
                    .and("startDate").gte(lowerDate)
                    .and("startDate").lt(upperDate)
            ), Event.class);
}

抛出执行此异常时：

当未使用两个LocalDate标准之一时，不会发生此问题，例如

public List<Event> findSubEventsBetweenDates(Event parentEvent, LocalDate lowerDate, LocalDate upperDate) {

    return mongo.find(query(
            where("parentEvent").is(parentEvent)
                    .and("startDate").gte(lowerDate)
                    //.and("startDate").lt(upperDate)
            ), Event.class);
}

两者中的哪一个被注释掉都没关系。所以问题必须是，同一领域有两个标准。有人暗示我吗？

2 个答案:

答案 0 :(得分：3)

使用

new Criteria().andOperator(
    where("parentEvent").is(parentEvent), 
    where("startDate").gte(lowerDate), 
    where("startDate").lt(upperDate))

代替。

答案 1 :(得分：0)

如果您将LocalDate更改为String，则会发现更明确的错误消息。

match(where("registerTime").gte(start.toString()).and("registerTime").lt(end.toString()))

然后在这种情况下错误消息是

org.springframework.data.mongodb.InvalidMongoDbApiUsageException: Due to limitations of the com.mongodb.BasicDBObject, you can't add a second 'registerTime' expression specified as 'registerTime : { "$lt" : "2017-06-11"}'. Criteria already contains 'registerTime : { "$gte" : "2017-06-10"}'.
