Groovy script to compare 2 JSON array objects - json

Question

I am trying to find the best way to compare 2 JSON Array objects using Groovy script.
JSON Obj1 =
{
"PO":
[
{
"OrderNumber": "12345",
"Location": "US",
}
{
"OrderNumber": "11223",
"Location": "US",
}
]
}
JSON Obj2 = {
"ResultPO":
[
{
"OrderNumber": "12345_00001",
"Location": "US",
"Customer": "ABC"
}
{
"OrderNumber": "98765_00002",
"Location": "US",
"Customer": "XYZ"
}
]
}
I need to return the JSON Output as below after finding the obj1 value in obj2 where OrderNumber is key identifier.
{
"ResultPO":
[
{
"OrderNumber": "12345_00001",
"Location": "US",
"Customer": "ABC"
}
]
}
Below is the sample code I have tried using JsonSlurper and findall but not able to get desired outcome.
def builder
def filterJson
filterJson = Obj2.findAll(){ it.OrderNumber.substring(0,4) == Obj1.OrderNumber.text()}
builder = new JsonBuilder(filterJson)

Answer 1

Try this one:
class OrderFilterSpec extends Specification {
def str1 = """{"PO":[
{"OrderNumber": "12345","Location": "US"},
{"OrderNumber": "11223","Location": "US"}
]}"""
def str2 = """{"ResultPO":[
{"OrderNumber": "12345_00001","Location": "US","Customer": "ABC"},
{"OrderNumber": "98765_00002","Location": "US","Customer": "XYZ"}
]}"""
def slurper = new JsonSlurper()
def buildResult(String first, String second) {
def (parsed1, parsed2) = [slurper.parseText(first), slurper.parseText(second)]
def filteredOrders = parsed2.ResultPO.findAll {
it.OrderNumber[0..4] in parsed1.PO.collect { it.OrderNumber }
}
return [ResultPO: filteredOrders]
}
def 'test order filtering'() {
expect:
buildResult(str1, str2) == [ResultPO: [[OrderNumber: '12345_00001', Location: 'US', Customer: 'ABC']]]
}
}
