How to set the order of json properties when sending a Map object

Question

I am sending a HashMap object as response from my RestController.

@GetMapping("/balance")
    public Map<String, Object>  fetchAccountsByBalance(){
         Map<String, Object> response = new HashMap<>();
         response.put("records", totalNumberOfRecords);
         response.put("pages", totalPages);
         response.put("data", pageResponse.getContent());
}

How to control the order of JSON properties when returning a Map object?

Looking at your code, I would suggest, instead of returning a map, you should return an object say Page. And in Page class, define 3 variables records,pages, and data .That is more concise and will maintain order — Ashishkumar Singh, Aug 31 '21 at 05:22

LinkedHashMap maintains insertion order:

Map<String, Object> response = new LinkedHashMap<>();
