我无法让它工作:db.library.update({categories:{$all:['/movie/action','/movie/comedy'],$nin:['/movie/cartoon']},location:{$geoWithin:{$centerSphere:[[48.8574946,2.3476296000000048],50/6378.1]}}},{$setOnInsert:{categories:['/movie/action','/movie/comedy'],location:{type:'Point',coordinates:[48.8574946,2.3
我有这个文件集:[{"name":"name1","data":[{"numbers":["1","2","3"]}]},{"name":"name2","data":[{"numbers":["2","5","3"]}]},{"name":"name3","data":[{"numbers":["1","5","2"]}]},{"name":"name4","data":[{"numbers":["1","4","3"]}]},{"name":"name5","data":[{"numbers":["1","2"]}]}]当作为参数传递的数组是data.numbers的子集时，我想获
假设我有一些名为candidates的集合。我想在此集合中的所有字段上创建一个text索引。在mongo中，我知道我可以这样做db.candidates.createIndex({"$**":"text"},{name:"TextIndex"})这是我的javapojo或实体。@Document(collection="candidates")publicclassCandidate{@IdprivateStringid;privateStringfirstName;privateStringlastName;//Otherstuff:removedforbrevity}现在如何在ja
我在MongoDB中有一组数据对象-[{"status":"passed","version":"124","value":6},{"status":"passed","version":"123","value":10},{"status":"failed","version":"123","value":16}]我想以这样的格式获取它-[{version:124,"series":[{"name":"passed","value":6}]},{version:123,"series":[{"name":"passed","value":10},{"name":"failed","v
如果没有传递查询参数，我将尝试从我的Mongo集合中返回所有文档。目前我有3个可选的查询参数可以由用户传递。localhost:3000/api/projects//shouldreturnallprojects.Currentlythisisreturning[]localhost:3000/api/projects?id=1//shouldreturnprojectswithidof"1".Workingproperly.localhost:3000/api/projects?name=myproject//shouldreturnprojectswithnameof"myproj
我有如下文档Document{BigDecimaloriginalPriceBigDecimaldiscounPrice}现在我想得到结果，其中[originalPrice-discountPrice]的结果以分页方式从最大差异到最小差异。有没有一种方法可以使用springdatamongodb来实现这一点，而不必在第三个字段中保存差异而不是查询第三列？更新:根据@HbnKing的回答，我使用spring-data-mongodb尝试了以下操作，但现在出现错误ProjectionOperationprojectionOperation=project("originalPrice","
带有MongoDB的Spring数据1.0.0.M3。spring怎么可以映射这个类:importorg.springframework.data.document.mongodb.index.IndexDirection;importorg.springframework.data.document.mongodb.mapping.Document;@DocumentpublicclassEnumsMapper{privateIndexDirectiond=IndexDirection.ASCENDING;}这个失败了:importorg.springframework.data.d
我需要在文档的字段数组中插入一些元素。好吧……我知道Mongo有原子更新。推送……事实是我需要在很多文档中做这个插入。情况如下(我需要为每个用户名插入一个角色数组):publicoverridevoidAddUsersToRoles(string[]usernames,string[]roleNames){foreach(stringroleinroleNames){if(!this.RoleExists(role)){thrownewProviderException(String.Format("Therole'{0}'wasnotfound.",role));}}//Howtog
我使用SpringData(1.3.0.RC1)访问我们的MongoDB，对于一些新查询，我想使用聚合框架。在mongoshell中，命令是:db.spotreports.aggregate({"$unwind":"$pd"},{"$group":{"_id":"$pd.PDch","base":{$sum:"$pd.aBL"},"uplift":{$sum:"$pd.up"}}}){"result":[{"_id":5,"base":529133,"uplift":21516},...我使用的Spring代码是:Aggregationagg=Aggregation.newAggreg
我无法将以下mongodb聚合操作转换为SpringDataAggregationOperation。我正在使用SpringDataMongoDB1.3.2版本。db.ads.aggregate({$group:{_id:"$adId",req:{$sum:1},imp:{$sum:{$cond:[{$eq:["$imped",true]},1,0]}},click:{$sum:{$cond:[{$eq:["$clked",true]},1,0]}},bid:{$sum:{$cond:[{$eq:["$clked",true]},"$bid",0]}}}});我停在这里:Aggrega
