问题查询工作正常但没有限制和跳过，它正在一次获取所有记录。请指出我做错了什么。MongoDB集合{"_id":ObjectId("559666c4e4b07a176940c94f"),"postId":"559542b1e4b0108c9b6f390e","user":{"userId":"5596598ce4b07a176940c943","displayName":"User1","username":"user1","image":""},"postFor":{"type":"none","typeId":""},"actionType":"like","isActive":1,
我正在尝试查找附近的地点。下面的代码工作正常。但是我无法根据给定的纬度、经度获得实际的位置距离。Criteriacriteria=newCriteria("coordinates").near(newPoint(searchRequest.getLat(),searchRequest.getLng()));Queryquery=newQuery();query.addCriteria(criteria);query.addCriteria(criteriaName);query.limit(5);Listls=(List)mongoTemplate.find(query,Place.c
我有这样的匹配标准-Criteriacriteria=newCriteria().and("paidMobileMetadata").in(metadataList).and("localDate").gt(startDate).lte(endDate);现在我想得到字段的总和，说“钱”属于上述标准，而不对某些字段进行分组。早些时候我遇到了同样的问题，我必须在某个字段上对这个匹配标准进行分组，我是这样做的-Aggregationagg=Aggregation.newAggregation(Aggregation.match(newCriteria().and("paidMobileMe
我在尝试使用聚合对象将我在mongodb中的查询转换为SpringDataMongoDb时遇到了问题。我在mongo中有以下文档:{"_id":ObjectId("596ce468798b61179c6442bb"),"_class":"com.test.model.User","name":"Oi","surName":"Alo","workLogs":[{"_id":ObjectId("596ce468798b61179c6442bc"),"day":1,"month":1,"year":2017,"timeEntrance":"8:00","lunchLeave":"12:00"
我有以下来自https://github.com/Apress/def-guide-to-mongodb/tree/master/9781484211830/The%20Definitive%20Guide%20to%20MongoDB的bson和json文件$ls.aggregation.bsonaggregation.metadata.jsonmapreduce.bsonmapreduce.metadata.jsonstorage.bsontext.json如何将它们导入MongoDB？我尝试将它们中的每一个都导入为一个集合，但失败了:$mongorestore-dtest-cag
我有一个MondoDB聚合管道，它通过聚合所有Sales来输出每日收入:Sale.aggregate([{$project:{day:{$substr:['$createdAt',0,10],},},},{$group:{_id:'$day',earnings:{$sum:'$pricing.earnings'},},},{$sort:{_id:1}},{$project:{date:'$_id',earnings:'$earnings',},},{$group:{_id:null,stats:{$push:'$$ROOT'},}},{$project:{stats:{$map:{//
我正在尝试获取已排序的不同字段的列表:publicListgetDistinctValues(Stringcollection,StringfieldName){Queryquery=newQuery();query.with(newSort(Sort.Direction.ASC,fieldName));returnmongoTemplate.findDistinct(query,fieldName,collection,Object.class);}但不应用排序。有什么办法可以用mongoTemplate来实现吗？spring-boot-starter-data-mongodb:2.
我正在使用spring-data-mongodb，我想使用游标进行聚合操作。MongoTemplate.stream()获取查询，因此我尝试创建聚合实例，使用Aggregation.toDbObject()DbObjectem>，使用DbObject创建了一个BasicQuery，然后调用stream()方法。这将返回一个空游标。调试spring-data-mongodb代码显示MongoTemplate.stream()使用FindOperation，这让我觉得spring-data-mongodb不支持流聚合操作。有没有人能够使用spring-data-mongodb流式传输聚合查
我在MongoDB中有这个查询:db.emailGroup.aggregate([{"$lookup":{"from":"link","localField":"_id","foreignField":"emailGroupId","as":"link"},},{"$unwind":"$link"},{"$match":{'link.originalLink':""}},{"$group":{_id:'$_id',link:{$push:'$link'}}},{"$project":{"size":{"$sum":{"$map":{"input":"$link","as":"l","i
我的MongoDb集合如下{"_id":ObjectId("5a187babdbf0a03cdca0d0bc"),"aggregationDate":"2017-10-31","ipaddress":"10.65.66.184","first":{"count":3},"second":{"count":2},"third":{"count":3},}{"_id":ObjectId("5a187babdbf0a03cdca0d0bd"),"aggregationDate":"2017-10-31","ipaddress":"10.65.66.182","first":{"count":
