JSON duplicate key, validate using java(spring)

Question

[
    {
    "id" : "Unique_Id25",
    "firstName" : "Test Name",
    "firstName" : "Test Name 2",
    }
]

Above I have an example of a duplicate key, firstName. I use Postman and it warns that a duplicate key exists, but the POST request passes as I don't currently validate for it.

So I'm asking if there's a cool java/spring way of checking for this duplicate and throwing an exception.

Otherwise I'll try to build these JSON keys into an array and looping through.

I've been using http://json-schema-validator.herokuapp.com/ to test but no success are validating duplicate key elements. — Darren Broderick DBro, Jun 17 '16 at 08:38

@Autowired
ObjectMapper jsonObjectMapper;

Use ObjectMapper to enable duplicate detection

jsonObjectMapper.enable(JsonParser.Feature.STRICT_DUPLICATE_DETECTION);
