Example for schema written in YAML and files to validate in JSON

[hasant73]

Hi there,

I have a quite complicated schema from my customer with a lot of references inside and I'm struggling to find a library that works with it.
Could you please give a example that accepts a YAML file as a schema and a JSON file as data to be validated.

My code looks like this so far:

ObjectMapper yamlReader = new ObjectMapper(new YAMLFactory());
Object obj = yamlReader.readValue(openAPIFile, Object.class);
ObjectMapper jsonWriter = new ObjectMapper();
String jsonSchemaStr = jsonWriter.writeValueAsString(obj);

ObjectMapper jsonReader = new ObjectMapper();
JsonNode node = jsonReader.readValue(inputFile, JsonNode.class);

// convert the schemas to json
JsonSchemaFactory factory = JsonSchemaFactory.getInstance(SpecVersion.VersionFlag.V4);
JsonSchema jsonSchema = factory.getSchema(jsonSchemaStr);
Set<ValidationMessage> validationMessage = jsonSchema.validate(node);
for (ValidationMessage v : validationMessage) {
  LOGGER.error(v.toString());
}
if (!validationMessage.isEmpty()) {
  throw new RuntimeException("Validation error");
}

Thanks you

Hi @hasant73, what about checking out how we are using it in our project with YAML schemas and JSON data validation?
Next to that, this project itself also has Unit tests with examples as well, checkout doc/quickstart.md for example.

This is how we're using it, in our project:
