vertx-json-validator

A simple JSON schema validator for the Vert.x world. This JSON validator is well adapted to be used in conjunction with Vert.x (https://vertx.io). At the moment it supports Draft 4, Draft 6 or Draft 7, and Java8+.

When to use this: There are a few good JSON schema validators out there, I was looking for a decent one that can integrate against Vert.x, yet ended empty handed. It’s simple to integrate and quite fast. The code includes a few samples of usage, so you just need to put the dependencies into your classpath, write a few simple lines of code, and that’s it!

Depedencies: vertx-core-3.x jackson-annotations-2.9.8 jackson-core-2.9.8 jackson-databind-2.9.8 netty-buffer-4.1.30.Final accessors-smart-1.2 asm-5.0.4 json-path-2.4.0 json-smart-2.3 slf4j-api-1.7.25 vertx-response (optional)

A quickstart:

String goodObjectJson_IV = "{\n" + " "fruits": [ "apple", "orange", "pear" ],\n" + " "vegetables": [\n" + " {\n" + " "veggieName": "potato",\n" + " "veggieLike": true\n" + " },\n" + " {\n" + " "veggieName": "broccoli",\n" + " "veggieLike": false\n" + " }\n" + " ]\n" + "}";

String schemaObjectData_IV = "{\n" + " "$id": "https://example.com/arrays.schema.json\",\n" + " "$schema": "http://json-schema.org/draft-07/schema#\",\n" + " "description": "A representation of a person, company, organization, or place",\n" + " "type": "object",\n" + " "properties": {\n" + " "fruits": {\n" + " "type": "array",\n" + " "items": {\n" + " "type": "string"\n" + " }\n" + " },\n" + " "vegetables": {\n" + " "type": "array",\n" + " "items": { "$ref": "#/definitions/veggie" }\n" + " }\n" + " },\n" + " "definitions": {\n" + " "veggie": {\n" + " "type": "object",\n" + " "required": [ "veggieName", "veggieLike" ],\n" + " "properties": {\n" + " "veggieName": {\n" + " "type": "string",\n" + " "description": "The name of the vegetable."\n" + " },\n" + " "veggieLike": {\n" + " "type": "boolean",\n" + " "description": "Do I like this vegetable?"\n" + " }\n" + " }\n" + " }\n" + " }\n" + "}";

        schema = new JsonObject(schemaObjectData_IV);
        sc = JsonSchemaResolver.resolveSchema(schema.getMap());
        
        Result result = JsonSchema.conformsSchema(new JsonObject(goodObjectJson_IV),sc);
        assertTrue(result.result());  

Have fun!
