Groovy to collect and remove duplicates from a complex json structure - recursion

Question

this is my first question at Stack Overflow, so, firstly, Hello colleagues and many thanks in advance.
I have this json input message I'm dealing with, but I cannot find the key to get the message I need for further processing

For a known id ("Payer_161185" or "ShiptoInc_161185") and a given value ("100563692") we need to extract all repetitions of businessEntities.codes of all UIDs and after get the list, remove duplicates.
For example, for "ShiptoInc_161185", the desired output would be:
{ "salesAreas": ["HU50_HU50_10_10","HU50_HU50_20_20"]}
This output is the list of salesAreas for the given value 100563692 into all the id = ShiptoInc_161185
Other case that I would like to solve is:
How could I add the id instead of text salesAreas?. Something like this {"Payer_111":["HU50_HU50_10_10","HU50_HU50_30_20"],"Payer_222":["HU40_HU40_10_10","HU20_HU20_30_20"]}. This means the id wouldn't be provided, just the prefix Payer_
Your help is appreciated.
***I solved the second requirement
def data = new JsonSlurper().parseText(body);
def bModelsIdFiltered = data.results.groups.organizations.businessModels
.collect { it[0] }.flatten()
.findAll { it.id.contains('Payer_') }
def nList = [];
def rembM = bModelsIdFiltered.each{
it.businessEntities.codes.each { code ->
nList.add(code.plus(it.id))
}
}
println "nl " + nList;
def codesFiltered = nList
.findAll { '100563692' in it }
return codesFiltered;

Answer 1

If the structure is rigid and i understood the task correctly (namely, you should find codes that have value 100563692 in the same array), you can doing it like that:
class FindCodesSpec extends Specification {
def testString = '''<insert_your_string_here>'''
def flattenOnce(List array) {
return array.inject([]) { res, el -> res + el }
}
def findCodes(String message, String id, String code) {
def data = new JsonSlurper().parseText(message)
def bModelsIdFiltered = data.results.groups.organizations.businessModels
.collect { it[0] }.flatten()
.findAll { it.id == id }
def codesFiltered = flattenOnce(bModelsIdFiltered.businessEntities.codes)
.findAll { code in it }
def uniqueCodes = codesFiltered.flatten().unique() - code
return JsonOutput.toJson(['salesAreas': uniqueCodes])
}
def 'run test'() {
expect:
'''{"salesAreas":["HU50_HU50_10_10","HU50_HU50_20_20"]}''' == findCodes(testString, 'ShiptoInc_161185', '100563692')
}
}
