Mongo string query to MongoTemplate (java, springframework) - java

i have query
db.getCollection('collectionName').aggregate([
{
$project: {
'_id':1,
'arrayField': {
$filter: {
input: '$arrayField',
as: 'arrayField',
cond: { $or: [
{$eq: [ [LUUID("********-****-****-****-************")],['$$arrayField._id'] ] },
{$eq: [ [LUUID("********-****-****-****-************")],['$$arrayField._id'] ] }
] }
}
}
}
}])
How will it look in MongoTemplate? And it is possible to rewrite the cond?


cond rewritten as:
db.getCollection('collectionName').aggregate([
{
$project: {
'_id':1,
'arrayField': {
$filter: {
input: '$arrayField',
as: 'arrayField',
cond:
{ "$setIsSubset": [
{ "$map": {
"input": ["$$arrayField._id"],
"as": "el",
"in": "$$el"
}},
[ LUUID("********-****-****-****-************") ,LUUID("********-****-****-****-************")],
]}
}
}
}
}])

Is there a mongodb query to merge fields in a specific mongodb document

So,suppose I have a document like :
{
"country": "USA",
"capital": "Washington DC",
"language": "English",
"other": {
"China": {
"capital": "Shanghai",
"language": "Chinese"
},
"Spain": {
"capital": "Madrid",
"language": "Spanish"
}
}
}
Now I want to return my document as:
{
"country": "USA",
"capital": "Washington DC",
"language": "English",
}
when I choose the country as "USA" but when I have the country set as "Spain", then I want my mongodb query to return the document as:
{
"country": "Spain",
"capital": "Madrid",
"language": "Spanish",
}
The fields should merge in accordance with the country specified in the "other" field.
How can I achieve this?

Try this one:
country = "Spain"
db.collection.aggregate([
// Make a uniform structure (why do you have 'USA' and 'other'?)
{ $replaceRoot: { newRoot: { $mergeObjects: ["$other", { USA: { capital: "$capital", language: "$language" } }] } } },
{ $project: { countries: { $objectToArray: "$$ROOT" } } },
{
$set: {
countries: {
$filter: {
input: "$countries",
cond: { $eq: ["$$this.k", country] }
}
}
}
},
{
$replaceRoot: {
newRoot: {
$mergeObjects: [
{ country: { $first: "$countries.k" } },
{ $first: "$countries.v" }]
}
}
}
])

Java Jolt bazaarvoice nested array

I am using Jolt to transform data from

But it doesn't work properly. What have i missed?

Figured it out.

Java Driver representation of Mongodb aggregation

I have the following aggregation which Im not able to figure out how to represent in Java/Springboot mongodb driver.
db.metric.aggregate([
{ $match: { "key.runid":1} },
{ "$project": {
"data": {
"$filter": {
"input": { "$objectToArray": "$$ROOT.metricData" },
"cond": { "$ne": [ "$$this.k", "_id" ] }
}
}
}},
{ "$unwind": "$data" },
{ "$group": {
"_id": "$data.k",
"v": { "$avg": "$data.v" }
}},
{ "$sort": { "_id": 1 } },
{ "$group": {
"_id": null,
"data": { "$push": { "k": "$_id", "v": "$v" } }
}},
{ "$replaceRoot": {
"newRoot": { "$arrayToObject": "$data" }
}}
])
I have attempted the following but being new to this Im not able to figure out how to write the filter for the data field :
Aggregation aggregation = newAggregation(
match(getCriteriaForMetricKey(keys)),
project("data", ""));
Can someone help me out.

Please help.

JSONSimple. AS Simple as it gets. Try it! https://www.mkyong.com/java/json-simple-example-read-and-write-json/

If I understood correctly what you mean, you can do somthing like this :
public class EntiteFile extends Serializable{
private List<Entite<Filed>> entites;
....
}
public class Entite<Filed> extends Serializable {
private List<Filed> fileds;
}
public clas Value extends Serializable {
private String value;
....
}
public class Filed extends Serializable {
private String name;
private List<Value> values ;
.....
}
and to read you're file you can use :
EntiteFile entities = mapper.readValue(getJsonFile(nameFile), EntiteFile.class);
for(Entite entite : entities.getEntites ){
for(Field field : Fields ){
if("detected-by".equals(field.getName())){
field.setName("Reported by");
for(Value value : field.getValues){
value.setValue("Adwait");
}
}
}
}
...
