Transform array to sub-values using jolt

I'm struggling to trans my input response to a specific output using jolt, below is my example
The input that describe my message
{
"firstAttribute": true,
"secondAttribute": "12",
"data": {
"propertyKey1": "1",
"propertyKey2": [
"a"
],
"propertyKey3": "2",
"propertyKey4": "3",
"propertyKey_test": [
"option1",
"option2",
"option3"
],
"propertyKey5": "4",
"propertyKey6": "87.0"
},
"Keytest1": "value1",
"KeyTest2": "value2"
}
The used jolt Spec
[
{
"operation": "shift",
"spec": {
"data": {
"propertyKey2": {
"0": "propertyKey2"
},
"*": {
"#": "data.&"
}
},
"*": {
"#": "&"
}
}
}
]
My actual output after a jolt transfomration
{
"firstAttribute" : true,
"secondAttribute" : "12",
"data" : {
"propertyKey1" : "1",
"propertyKey3" : "2",
"propertyKey4" : "3",
"propertyKey_test" : [ "option1", "option2", "option3" ],
"propertyKey5" : "4",
"propertyKey6" : "87.0"
},
"propertyKey2" : "a",
"Keytest1" : "value1",
"KeyTest2" : "value2"
}
The desired output is to convert every array fields to separated fields such as propertyKey_test as below
{
"firstAttribute" : true,
"secondAttribute" : "12",
"data" : {
"propertyKey1" : "1",
"propertyKey3" : "2",
"propertyKey4" : "3",
"propertyKey_test": "option1",
"propertyKey5" : "4",
"propertyKey6" : "87.0"
},
"propertyKey2" : "a",
"Keytest1" : "value1",
"KeyTest2" : "value2"
}
Any help would be appreciated. Thanks in advance
PS: we can receive a dynamic array fields (ex: today we have propertyKey_test:["option1","option2","option3"] tomorrow we could receive another array field for example new_field:["a","b","c"].
My goal is to check everytime if the field is an array and take just the first element as described above

The current desired output is not a valid JSON value, since there may not exist more than one attribute with identical key within a common object. But, if you need to differentiate the components of the "propertyKey_test" array, then using the indexes of the array as below might be preferred such as
[
{
"operation": "shift",
"spec": {
"data": {
"propertyKey2": {
"0": "&1"
},
"*": {
"#": "&2.&"
},
"propertyKey_*": {
"*": {
"#": "&3.&2&1"
}
}
},
"*": {
"#": "&"
}
}
}
]
in order to get
{
"firstAttribute" : true,
"secondAttribute" : "12",
"data" : {
"propertyKey1" : "1",
"propertyKey3" : "2",
"propertyKey4" : "3",
"propertyKey_test0" : "option1",
"propertyKey_test1" : "option2",
"propertyKey_test2" : "option3",
"propertyKey5" : "4",
"propertyKey6" : "87.0"
},
"propertyKey2" : "a",
"Keytest1" : "value1",
"KeyTest2" : "value2"
}
as output.

How to update multiple fields(array field and normal field) in a single document of mongo db at a time using JAVA?

I want to update request fields only in an array using java.This is my existing document in mongo db:
{
"_id": "6691e5068dwe335w42cb0a699650f",
"Opportunity_Owner": "Self",
"Account_Name": "IC",

},
{
"id": "1557389978181",
"Notes": "Spoken to Bobby."
},
{
"id": "1557389990159",
"Notes": "plan to call on 29/Apr"
}
],
"createdBy": "2c18b8dbb7d74a41a66f53a90117480a",
"createdDate": "1562911250917"
}
Request payload:
{
"_id" : "6691e5068dwe335w42cb0a699650f",
"Stage_Status" : "I",
"1555556059584" : [
{
"id" : "1557389940585",
"Notes" : "updated note 123"
}
]
}
I am trying to update "Stage_Status" and "1555556059584.Notes" at a time using $set.I am able to update "Stage_Status" but "1555556059584" array is going to reset with what i have updated with last one.
expected output:
{
"_id" : "6691e5068dwe335w42cb0a699650f",
"Opportunity_Owner" : "Self",
"Account_Name" : "IC",
"Lead_Source" : "Callbox",
"Opportunity_Name" : "name1 ",
"Stage" : "Proposal",
"Stage_Status" : "I",
"1555570551211" : [],
"1555556165153" : [],
"1555556059584" : [
{
"id" : "1557389940585",
"Notes" : "updated note 123"
},
{
"id" : "1557389945398",
"Notes" : "Hi Bobby "
},
{
"id" : "1557389978181",
"Notes" : "Spoken to Bobby."
},
{
"id" : "1557389990159",
"Notes" : "plan to call on 29/Apr"
}
],
"createdBy" : "2c18b8dbb7d74a41a66f53a90117480a",
"createdDate" : "1562911250917"
}
can any one please help me to figure it out in java.

I guess you wanted to update Stage_Status and 1555556059584.Notes at Once .
here is a demo about it
> db.student.find()
{ "_id" : ObjectId("5d2c09ea8ed60ae70d3dd76b"), "name" : "bigbang", "courses" : [ { "name" : "en", "classRoom" : "9001" }, { "name" : "math", "classRoom" : "1001" } ] }
> db.student.update({name:'bigbang','courses.name':'en'},{ $set: {'courses.$.classRoom':'1009',name :"course"} })
WriteResult({ "nMatched" : 1, "nUpserted" : 0, "nModified" : 1 })
> db.student.find()
{ "_id" : ObjectId("5d2c09ea8ed60ae70d3dd76b"), "name" : "course", "courses" : [ { "name" : "en", "classRoom" : "1009" }, { "name" : "math", "classRoom" : "1001" } ] }
the java demo is like this
collection.updateOne(and(eq("Stage_Status","A"),eq("1555556059584.id","1557389940585")),new Document("$set" ,new Document("Stage_Status","YOUR_NEW_VALUE").append("1555556059584.$.Notes","YOUR_NEW_VALUE")));
you must set the 1555556059584.id to let the diver know which element to be update .

How to get the Content from Specific Field from JSONObject Data

i want to get from this JSONObject Data , the content of field "_source",
JSONObject jsonObj =
{
"hits" : [
{
"_index" : "try1",
"_type" : "_doc",
"_id" : "1",
"_score" : 1.0,
"_source" : {
"target" : {
"br_id" : 0,
"wo_id" : 2,
"process" : [
"element 1",
"element 2"
]
},
"explanation" : {
"an_id" : 1311,
"pa_name" : "micha"
},
"text" : "hello world"
}
}
]
}
the Result should be like bellow ,
String result =
{
"target" : {
"br_id" : 0,
"wo_id" : 2,
"process" : [
"element 1",
"element 2"
]
},
"explanation" : {
"an_id" : 1311,
"pa_name" : "micha"
},
"text" : "hello world"
}
I tried this , but it always could not recognize the "_source" field,
JSONObject main = jsonObj.getJSONObject("hits");
JSONObject content = main.getJSONObject("_source");
JSONObject field = content.getJSONObject("target");
JSONObject["_source"] not found
JSONObject["target"] not found
Please any suggestion or Advices, so i can get the Content from "_source" as Result?
thx.

_source is inside of JSONArray hits, so first get the JSONArray
JSONArray main = jsonObj.getJSONArray("hits");
And then get the first JSONObject from array
JSONObject obj = main.getJSONObject(0);
JSONObject source = obj.getJSONObject("_source"); //now get the _source

This is not hard if you use some tools to generate the code from json strings.Like this one:http://jsongen.byingtondesign.com/.
I'm sure there are more useful tools to do this work.

How to decode this nested JSON string?

i tried many times to decode nested JSON string which consist of nested Array , i used GSON() to do that. and it's worked , but the problem is about objects inside this array don't be decoded from json, so i want your help :
JSON String :
{ "data" : { "current_condition" : [ { "cloudcover" : "75",
"humidity" : "87",
"observation_time" : "03:16 AM",
"precipMM" : "1.5",
"pressure" : "991",
"temp_C" : "11",
"temp_F" : "52",
"visibility" : "7",
"weatherCode" : "293",
"weatherDesc" : [ { "value" : "Patchy light rain" } ],
"weatherIconUrl" : [ { "value" : "http://cdn.worldweatheronline.net/images/wsymbols01_png_64/wsymbol_0033_cloudy_with_light_rain_night.png" } ],
"winddir16Point" : "SSW",
"winddirDegree" : "210",
"windspeedKmph" : "30",
"windspeedMiles" : "19"
} ],
"request" : [ { "query" : "London, United Kingdom",
"type" : "City"
} ],
"weather" : [ { "date" : "2014-01-03",
"precipMM" : "6.9",
"tempMaxC" : "10",
"tempMaxF" : "50",
"tempMinC" : "5",
"tempMinF" : "41",
"weatherCode" : "293",
"weatherDesc" : [ { "value" : "Patchy light rain" } ],
"weatherIconUrl" : [ { "value" : "http://cdn.worldweatheronline.net/images/wsymbols01_png_64/wsymbol_0017_cloudy_with_light_rain.png" } ],
"winddir16Point" : "SW",
"winddirDegree" : "220",
"winddirection" : "SW",
"windspeedKmph" : "33",
"windspeedMiles" : "21"
} ]
} }
my Code to decode this JSON :
HashMap HashMap = new Gson().fromJson(json, HashMap.class);
and it's output :
{data={request=[{query=London, United Kingdom, type=City}],
current_condition=[{cloudcover=75, humidity=87, observation_time=03:16
AM, precipMM=1.5, pressure=991, temp_C=11, temp_F=52, visibility=7,
weatherCode=293, weatherDesc=[{value=Patchy light rain}],
weatherIconUrl=[{value=http://cdn.worldweatheronline.net/images/wsymbols01_png_64/wsymbol_0033_cloudy_with_light_rain_night.png}],
winddir16Point=SSW, winddirDegree=210, windspeedKmph=30,
windspeedMiles=19}], weather=[{date=2014-01-03, precipMM=6.9,
tempMaxC=10, tempMaxF=50, tempMinC=5, tempMinF=41, weatherCode=293,
weatherDesc=[{value=Patchy light rain}],
weatherIconUrl=[{value=http://cdn.worldweatheronline.net/images/wsymbols01_png_64/wsymbol_0017_cloudy_with_light_rain.png}],
winddir16Point=SW, winddirDegree=220, winddirection=SW,
windspeedKmph=33, windspeedMiles=21}]}}
so i want an ideal method to give me ability to enter this nested HashMap array and it's values , because my method don't give me ability to call nested values from this array
Thank you ,

as the string represents a Hashmap inside another Hashmap you can use some thing like,
HashMap<String, HashMap> hashMap = new Gson().fromJson(json, HashMap.class);

It's worked after i did this method :
Type type = new TypeToken< HashMap<String, HashMap<String, ArrayList<com.google.gson.internal.LinkedTreeMap>>>>() {}.getType();
HashMap<String, HashMap<String, ArrayList<com.google.gson.internal.LinkedTreeMap>>> hashMap = new Gson().fromJson(API.getJSON(), type);
com.google.gson.internal.LinkedTreeMap hash = hashMap.get("data").get("current_condition").get(0);
System.out.println(" "+hash.get("humidity")+" ");
i know that your answers and my first method are true , but as i told you that i want to enter the entry nested array list inside this Json
