json-schema-validator
A JSON Schema validation implementation in pure Java, which aims for correctness and performance, in that order
JSON Schema validation online validate your json data against a json schema
I've a json schema like this:
{
"$schema": "http://json-schema.org/draft-04/schema#",
"title": "Operation",
"description": "The schema of an operation",
"type": "object",
"properties": {
"id":{
"description": "Unique identifier of the service",
"type": "string"
},
"description":{
"type": "string"
},
"dateDebut":{
"type": "string",
"format": "date-time"
},
"dateFin":{
"type": "string",
"format": "date-time"
}
}
}
How can I say in my schema that the dateFin must be greater than the dateDebut ?

I am building a JSON for a REST web service. The schema however has grown to over 1300 lines and I want to split it up across multiple files. I am unit testing my schema against a folder of JSON sample responses using json-schema-validator version 2.1.8.
I know you have import types defined in your current file like { "$ref": "#/definitions/MyBool" }, however if I wanted to move the definition of MyBool to another file, like Common.schema.json, how would I reference it then?
I tried { "$ref": "Common.schema.json/definitions/MyBoolean" }, { "$ref": "./Common.schema.json/defintion/MyBoolean" }, and { "$ref": "file://./Common.schema.json/definitions/MyBoolean" } but none of them work.
The answer on "Does JSON Schema validation in common-js utils support references?" seems like it should work but I can't seem to get the syntax right.
I'm loading the schema with:
JsonNode mySchema = JsonLoader.fromReader( new InputStreamReader( JsonSchemaTest.class.getResourceAsStream( "/json/schema/MySchema.schema.json" ) ) );
and then validating it with:
JsonSchemaFactory.byDefault().getValidator().validate( schema, new InputStreamReader( getClass().getResourceAsStream( "/json/sample/MyJsonSample.json" ) ) ).isSuccess();
FWIW MyBool looks like:
"MyBool": {
"type": "object",
"properties": {
"value" :{
"type": "string",
"enum": [ "true", "false", "file not found" ]
}
},
"required": ["value"],
"additionalProperties": false
}
When I don't try to extract MyBool, the schema validates all my JSON samples correctly.
The exception I receive is:
com.github.fge.jsonschema.core.exceptions.ProcessingException: fatal: unable to dereference URI "file:/Common.schema.json/definitions/MyBool#"
level: "fatal"
uri: "file:/Common.schema.json/definitions/MyBool#"

I have a Json schema as below , when i validate it on a online validatior like http://jsonschemalint.com/draft4/# it says its valid.I changed "type" to "object" , "array" , "string" and kept the rest of the structure same .still it says valid schema. My understanding was when
type=object there should be "properties"
when type=array there should be"items"
{
"title": "Example Schema",
"type": "string",
"properties": {
"firstName": {
"type": "string"
},
"lastName": {
"type": "string"
}
},
"required": [
"firstName",
"lastName"
]
}

How does jsonschema work?
My assumption is that they convert the raw json strings they see into the python type that is listed in say jsonschema.Draft4Validator.DEFAULT_TYPES and see if it can be converted. If the convert is successful, then validation proceeds.
If that's the case, each of the types in python in DEFAULT_TYPES must have a "from string" method that converts a string to that type.
Is my understanding of jsonschema correct?

I'm working with Spring Boot and REST Assured to test REST APIs. I was trying the example with JSON schema validation but it throws this error:
java.lang.IllegalArgumentException: Schema to use cannot be null
According to documentation, the schema should be located in the classpath. My example schema is located there. Here is my project structure and example schema location:
Here is my code. Without schema validation it works fine.

If you specify elements in the input file that is configured as a requirement in the schema, it is validating OK.
And if you append the “maxItems”: 1, it does not care if you add another element in the input file, the validator still look at this as a valid input file.
i.e:
Schema:
{
"$schema": "http://json-schema.org/draft-04/schema#",
"type": "object",
"properties": {
"Books": {
"type": "object",
"minItems": 1,
"properties": {
"Book": {
"type": "object",
"minItems": 1,
"maxItems": 1,
"properties": {
"Author": {
"type": "string",
"minItems": 1,
"maxItems": 1
}
},
"required": ["Author"]
}
},
"required": ["Book"]
}
},
"required": ["Books"]
}
InputFile:
{
"Books": {
"Book": {
"Author": "Andreas",
"Author": "Geir"
}
}
}
Shouldn't this be a invalid inputfile?

I need to write the JSON Schema based on the specification defined by http://json-schema.org/. But I'm struggling for the required/mandatory property validation. Below is the JSON schema that I have written where all the 3 properties are mandatory but In my case either one should be mandatory. How to do this?.
{
"id": "http://example.com/searchShops-schema#",
"$schema": "http://json-schema.org/draft-04/schema#",

How can I set Multiple type in a JsonSchema.
The description field in the below example I want it to be JsonSchemaType.String or JsonSchemaType.null.
{PropertyNames.Id, new JsonSchema { Type = JsonSchemaType.Integer, Required = true }},
{PropertyNames.Description, new JsonSchema { Type = JsonSchemaType.String, Required = true }}
Also, I have an array which consists of Integers and float.
result[PropertyNames.Metrics] = new JsonSchema { Type = JsonSchemaType.Array, Required = true, Items = new List<JsonSchema> { new JsonSchema() { Type = JsonSchemaType.Integer } } };
The validation fails as it expects integer but receives float. Can I do something like Type = JsonSchemaType.Integer "or" JsonSchemaType.Float

We are using Spring Integration to process a JSON payload passed into a RESTful endpoint. As part of this flow we are using a filter to validate the JSON:
.filter(schemaValidationFilter, s -> s
.discardFlow(f -> f
.handle(message -> {
throw new SchemaValidationException(message);
}))
)
This works great. However, if the validation fails we want to capture the parsing error and return that to the user so they can act on the error. Here is the overridden accept method in the SchemaValidationFilter class:
@Override
public boolean accept(Message<?> message) {
Assert.notNull(message);
Assert.isTrue(message.getHeaders().containsKey(TYPE_NAME));
String historyType = (String)message.getHeaders().get(TYPE_NAME);
JSONObject payload = (JSONObject) message.getPayload();
String jsonString = payload.toJSONString();
try {
ProcessingReport report = schemaValidator.validate(historyType, payload);
return report.isSuccess();
} catch (IOException | ProcessingException e) {
throw new MessagingException(message, e);
}
}
What we have done is in the catch block we throw a MessageException which seems to solve the problem. However this seems to break what a filter should do (simply return a true or false).
Is there a best practice for passing the error details from the filter to the client? Is the filter the right solution for this use case?
Thanks for your help!

I'm trying to create a JSON schema that allows for a nullable attribute. For example, I want the following JSON to be valid:
{
"some_name" : null
}
with the following schema:
{
"type": "object",
"properties": {
"some_name": {
"type": [
"string",
null
],
"maxLength": 100
}
}
}
However, it's invalid as it thinks that "null" can't have a maxLength. Is there a good way to do this? I wish there was a "nullable" attribute, or something of the sort!
