Dynamically Generate the JSON Schema from the JSON file in JAVA without using the POJO

Question

Any suggestions for getting the JPATH's for the input JSON file. Basically a tree structure of the JSON schema from the JSON file

Answer 1

You should be okay to use JsonParser this way;

First, get the JSON file content as a String. (Say jsonString )
Then code something like this;

JsonParser parser = new JsonParser();
JsonObject o = parser.parse(jsonString).getAsJsonObject();

Once you have the JSON Object, you can use the JsonPath library to get what you may need.

Hope this helps!

Json file or string to JsonNode, then

JsonSchemaInferrer.newBuilder()
  .setSpecVersion(SpecVersion.DRAFT_06).build()
