Have a look at my answer here with a solution for this:

Validating json payload against swagger file - json-schema-validator

It's based on using the library: https://github.com/bjansen/swagger-schema-validator. It allows to check your json against the definitions contained in the swagger schema.

try (InputStream inputStream = schemaLocation.getInputStream()) {
            SwaggerValidator validator = SwaggerValidator.forJsonSchema(new InputStreamReader(inputStream));
            ProcessingReport report = validator.validate(message, "/definitions/Pet");
            return report.isSuccess();
        } catch (IOException e) {
            logger.error("IOException", e);
            return false;
        } catch (ProcessingException e) {
            e.printStackTrace();
            return false;
        }
