I am trying to validate a json payload against a swagger file that contains the service agreement. I am using the json-schema-validator(2.1.7) library to achieve this, but at the moment it's not validating against the specified patterns or min/max length.
Java Code:
public void validateJsonData(final String jsonData) throws IOException, ProcessingException {
ClassLoader classLoader = getClass().getClassLoader();
File jsonSchemaFile = new File (classLoader.getResource("coachingStatusUpdate.json").getFile());
String jsonSchema = new String(Files.readAllBytes(jsonSchemaFile.toPath()));
final JsonNode dataNode = JsonLoader.fromString(jsonData);
final JsonNode schemaNode = JsonLoader.fromString(jsonSchema);
final JsonSchemaFactory factory = JsonSchemaFactory.byDefault();
JsonValidator jsonValidator = factory.getValidator();
ProcessingReport report = jsonValidator.validate(schemaNode, dataNode);
System.out.println(report);
if (!report.toString().contains("success")) {
throw new ProcessingException (
report.toString());
}
}
Message I am sending through

As you can see I am sending through a correlationID of -1, which should fail validation, but at the moment is's returning as successful:
com.github.fge.jsonschema.report.ListProcessingReport: success
json-schema-validator seems to work with pure JSON Schema only. OpenAPI Specification uses an extended subset of JSON Schema, so the schema format is different. You need a library that can validate specifically against OpenAPI/Swagger definitions, such as Atlassian's swagger-request-validator.
I suggest using this library, which worked for me:
https://github.com/bjansen/swagger-schema-validator
Example:
invalid-pet.json
{
"id": 0,
"category": {
"id": 0,
"name": "string"
},
"named": "doggie",
"photoUrls": [
"string"
],
"tags": [
{
"id": 0,
"name": "string"
}
],
"status": "available"
}
My SchemaParser:
@Component
public class SchemaParser {
private Logger logger = LoggerFactory.getLogger(getClass());
public boolean isValid(String message, Resource schemaLocation) {
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;
}
}
}
A test:
@Test
void shouldFailValidateWithPetstoreSchema() throws IOException {
final Resource validPetJson = drl.getResource("http://petstore.swagger.io/v2/swagger.json");
try (Reader reader = new InputStreamReader(validPetJson.getInputStream(), UTF_8)) {
final String petJson = FileCopyUtils.copyToString(reader);
final boolean valid = schemaParser.isValid(petJson, petstoreSchemaResource);
assertFalse(valid);
}
}
