Criteria already contains 'xxx ：

• mongodb查询报错详情如下:

org.springframework.data.mongodb.InvalidMongoDbApiUsageException: Due to limitations of the com.mongodb.BasicDocument, you can't add a second '_id' expression specified as '_id : Document{{$in=[1000090]}}'. Criteria already contains '_id : 1000090'.

• 报错的原因是因为前面已经用了_id字段查询了又用了_id,语句如下:

Criteria.where("_id").in(id).and("_id").in(userIdArray);

• 解决方案可以使用andOperator语句

new Criteria().andOperator(Criteria.where("_id").is(id),
                            Criteria.where("_id").in(userIdArray));
