Json schema validation in Spring REST APIs

stackoverflow.com › questions › 34858709 › json-schema-validation-in-spring-rest-apis

If you take a look at JSON schema site, there are only two libraries for validation in Java.

The one that Jorge Campos suggested is mature, but looking for new maintainer: https://github.com/fge/json-schema-validator
Second one is relatively new: http://github.com/everit-org/json-schema

I was recently in situation where I had to choose one or the other and I picked first option. It is being used also by Rest Assured library under the hood.

How To Perform JSON Schema Validation

July 8, 2024 - Next, let's talk about the properties block inside the JSON Schema. The following block states that bookingid should be in the root object and its type should be integer . Hence, in response, it is expected that the value in this field should be an integer only. So, in case this type is changed to any other data type like String ,Object ,longor float, schema validation will fail and we would be able to identify the issue in the schema right away.

Fix

JsonSchemaFactory.getInstance(VersionFlag.V7).getSchema(schemaPath.getInputStream());

Remove the s from https for the URI of draft-07.

The URI for draft-07 is http://....

The URI used to identify a schema dialect is not necessarily network addressable... in other words, "It's just a string", which should match completely.
