graphql-java-extended-validation

Enables validation rules like @Size and @Pattern to be defined directly in GraphQL schema language, providing a clear, schema-first approach inspired by Java Bean Validation.

Supports Java Expression Language in @Expression directive, allowing access to validation context variables for advanced rule definitions beyond simple constraints.

Integrates with ResourceBundleMessageInterpolator for localized error messages, enabling custom templates and locale-specific validation feedback as described in the documentation.

Uses ValidationSchemaWiring to automatically enhance data fetchers with validation, minimizing code changes and aligning with graphql-java's extensible design.

Allows implementation of custom ValidationRule interfaces, providing flexibility to add project-specific validation logic alongside standard directives.
