1 Introduction

It is targeted at developers who want to structure the web service layer of an application in a JSR 311 compatible way but still want to continue to use Grails' powerful features such as GORM, automated XML and JSON marshalling, Grails services, Grails filters and so on. This plugin is an alternative to Grails' built-in mechanism for implementing RESTful web services.

Features

• Makes the JSR 311 (JAX-RS) available to Grails applications for developing RESTful web services.
• New Grails artefact types, Resource and Provider, for JAX-RS classes.
• JAX-RS Resource classes under grails-app/resources are auto-detected and can be modified at runtime.
• JAX-RS Provider classes under grails-app/providers are auto-detected and can be modified at runtime.
• Extended Grails command line interface
• Create new resources and unit test templates via grails create-resource <resource name>.
• Generate ready-to-use resources from domain objects via grails generate-resources <domain class name>.
• Scaffolding
• Generate RESTful service interfaces for Grails domain objects.
• Content negotiation support for XML and JSON representations.
• Ability to use any Grails feature within JAX-RS resources and providers such as:
• GORM can be used for interacting with persistent domain objects.
• Grails filters for intercepting requests to JAX-RS resources. ( Deprecated )
• Grails services which can be auto-injected by name.
• Entity providers
• Domain object providers that convert between Grails domain objects and XML or JSON representations.
• Support classes for developing custom entity providers.
• Support for content negotiation based on the Accept request header.
• Easy integration testing of JAX-RS resources and providers.
• Plugin users may choose between Jersey and Restlet as JAX-RS implementations by means of configuration.
• jaxrs applications can be deployed to Google App Engine (GAE).
