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

  • This question is similar to: creating Hashmap from a JSON String. If you believe it’s different, please edit the question, make it clear how it’s different and/or how the answers on that question are not helpful for your problem. Commented Mar 24 at 13:34
  • No my question is for a json which contains list of key value pair. The key is a complex type and the value is Integer type Map<ComplexDataClass,Integer> fileObjects = mapper.readValue(jsonString, new TypeReference<Map<ComplexDataClass,Integer>>(){}); Commented Mar 24 at 13:51
  • @TanyaBhandari The key issue is that your "json string" does not contain valid JSON; it's something else that's not JSON. Commented Jul 16 at 11:05
