Coverting map into a json schema

Question

I want to create the json schema of the following:

My java pojo looks like:

public class Filter {

    Map<String, Object> 
    Map<String, Integer> sort;
    int offset = -1;
    int limit = -1;
    List<String> responseFields;
}

My sample json looks like:

{
  "terms": {
    "foo":"bar",
    "foo1":1
  },
  "sort": {
    "foo": 1
  },
  "offset": 1,
  "limit": 25,
  "responseFields": ["foo", "foo1"]
}

I'm stuck at creating the json-schema for the terms and order fields. Can anyone please let me know how i could mode this?

Answer 1

Map<String, ???> can be described with { "type": "object", "additionalProperties": ??? }.

{
  "type": "object",
  "properties": {
    "terms": { "type": "object" },
    "sort": {
      "type": "object",
      "additionalProperties": { "type": "integer" }
    },
    "offset": { "type": "integer" },
    "limit": { "type": "integer" },
    "responseFields": {
      "type": "array",
      "items": { "type": "string" }
    }
  }
}
