How to generate dynamic JSON from database table records in Java 8

Question

I have below database table having records, table rows can have various string records, pattern of records is like showed in table.

"domainVal", "idVal", "versionVal" - these are constants no dynamic but all other keys are dynamic, can have any string.

payment[] This is JsonArray in JSON

I want to generate dynamic JSON from these kind of records.

1. I tried to create POJO but as records values are not constant it could be any string so can't create exact POJO,

2. Tried to create Java collection to fit these records in java collection and can create json from Java collection but could not figure-out how to parse these records and can store in Java collection.

Table -

domain	id	version
identifier.domainKey	identifier.idKey	identifier.versionKey
payload.account.domain	payload.account.id	payload.order.version.version
payload.order.domain	payload.order.id	payload.order.version.dealVersion
payload.customer.customerType.domain	payload.customer.customerType.id	payload.customer.customerType.version
payload.payment[].deal.domain	payload.payment[].deal.id	payload.payment[].deal.version
payload.payment[].dealType.domain	payload.payment[].dealType.id	payload.payment[].dealType.version

Expected Json from above table -

{
"identifier": {
    "domainKey": "domainVal",
    "idKey": "idVal",
    "versionKey": "versionVal"
},
"payload": {
    "account": {
        "domain": "domainVal",
        "id": "idVal",
        "version": "versionVal"
    },
    "order": {
        "domainKey": "domainVal",
        "idKey": "idVal",
        "version": {
            "dealVersion": "versionVal"
        }
    },
    "customer": {
        "customerType": {
            "domain": "domainVal",
            "id": "idVal",
            "version": "versionVal"
        }
    },
    "payment": [
        {
            "deal": {
                "domain": "domainVal",
                "id": "idVal",
                "version": "versionVal"
            }
        },
        {
            "dealType": {
                "domain": "domainVal",
                "id": "idVal",
                "version": "versionVal"
            }
        }
    ]
}

}

Please someone share me a java code/Algorithm for this..

A simple recursion method would help me, Or Is there any standard library to do this
