converted json result structure not same as source - json

Question

i have test case to compare against the source kept in Kafka message.
I noticed the structured is not same.
no missing field, but the structure is not arranged in the same sequence.
how do i make the result converted same as the source structure?
code to retrieve the message, then decode the base64 format and prettyprint the result.
def responseList = new JsonSlurper().parseText(consumeMessage.getResponseText())
println('response text: \n' + JsonOutput.prettyPrint(JsonOutput.toJson(responseList)))
def decoded = new JsonSlurper().parseText(new String(responseList[0].value.decodeBase64()))
println('response decoded text: \n' + JsonOutput.prettyPrint(JsonOutput.toJson(decoded)))
below is the result printed at console
2019-11-20 16:36:44.934 DEBUG oingDRToAllocationVerification-DynamicID - 10: decoded = JsonSlurper().parseText(new java.lang.String(responseList[0].value.decodeBase64()))
2019-11-20 16:36:44.945 DEBUG oingDRToAllocationVerification-DynamicID - 11: println("response decoded text:
" + JsonOutput.prettyPrint(JsonOutput.toJson(decoded)))
response decoded text:

Answer 1

As json.org says:
An object is an unordered set of name/value pairs.
So, different JSON methods/libraries might order them in a different way. You shouldn't rely on order of name/value pairs when working with JSON.
(If order is very important to you, you might try using suggested solution from this post.)
