hello Mkyong, currently i am using Embedded document design in mongodb. and i want to use it with spring data how can i do that
I am working on java application using mongo, I want to check if there is any other option to remove documents from collection after some time period… I checked createIndex option for implementing TTL .. but it needs timestamp column to be present in collection, is there any other way to implement TTL with timestamp column and createIndex option ?

Hello Mkyong!
I want to build a search panel, in which I will put name and it will show me all data from database related to that name.
I want to create that in java with database Mongodb
Hello Mkyong,
Is there any way to use multi update in same array object using java.
{
“_id” : ObjectId(“58859d758c0f1c0c385a2f42”),
“medications” : [
{
“id” : 23.0,
“name” : “A”,
“type” : “B”
},
{
“id” : 41.0,
“name” : “C”,
“type” : “D”
},
{
“id” : 41.0,
“name” : “C”,
“type” : “D”
}
]
}
db.tutorial.update({ “medications.id”: 41.0 },{“$set”:{“medications.$.name”:”Test”}},{“multi”:true})
above query is updating only one element in array
please help me soon.
Can you please share an example with MondoDB and Hibernate ?
I have this query in JS
arrStrudent = db.students.aggregate([{$project:{scores: {$filter: {input: “$scores”,as: “item”,cond: { $eq: [“$$item.type”, “homework”]}}}}},{“$unwind”: “$scores”},{ $sort : { _id : 1, scores: 1 } },{$project : { “scores.score” :1} }]);null;
var tmpId = -1;
while (arrStrudent.hasNext()) {v = arrStrudent.next();if (v._id != tmpId) {print(v._id + “==>” + v.scores.score);tmpId = v._id;db.students.update({ _id : v._id},{ $pull: { scores: { score : v.scores.score }}})}}
arrStrudent.close();
this is to remove lowest score within the scores array of student collections.
===============
Now I want do same in Java, can you help me with aggregate query ? I worte something like this, and this doesnt work.
AggregateIterable iterable = db.getCollection(“students”).aggregate(asList(
new Document(“$project”, new Document(“scores”, new Document(“$filter”, new Document(“input”,”$scores”).append(“as”, “item”).append(“cond”, new Document(“$eq”,new Document(“$$item.type”, “homework”))))))
));
=================
student collection looks like this.
{“_id” : 19,”name” : “Gisela Levin”,”scores” : [{“type” : “exam”,”score” : 44.51211101958831},{“type” : “quiz”,”score” : 0.6578497966368002},{“type” : “homework”,”score” : 93.36341655949683}]}
