I have a jsonString which is a list of key value pairs.

[
 {"id": "123", "url": "ghi"} : 2,
 {"id": "456", "url": "def"} : 3
]

How to convert to HashMap. Maps:

Key - {"id": "123", "url": "ghi"} value - 2 Key - {"id": "456", "url": "def"} value - 3

The key issue here is that the Key is a composite type and not a simple datatype
