Spring ws payloadvalidatinginterceptor example
With the Spring WS plugin, this is as simple as entering the following command: There are three important things to point out about the endpoint implementation.First, the name of the endpoint is important when it comes to which XML document payloads will be routed to this endpoint.There are several ways to get it done: - using xjc compiler - using Maven 2.x/3.x plugin (I lean towards this one and use it all the time) Ok, so we have our Java classes (with JAXB2 annotations), generated from our WSDL. Request Payload; import org.server.endpoint.annotation. Response Payload; import org.soap.server.endpoint.annotation. Soap Action; @Endpoint public class User Profile Endpoint There are a few important things to mention: - @Endpoint annotation tells Spring Web Services that we have web service endpoint - @Soap Action annotation (on the methods) tells Spring Web Services that method in question is responsible to handle particular SOAP action - @Response Payload and @Request Payload annotations tell Spring Web Services to extract payload from SOAP message, deserialize it to Java classes (using JAXB2 binding), and match input/output parameters against declared handlers (methods) That's pretty much it to make things work!As picture describes, we have User Profile Service web service with User Profile operations which accepts User Profile Request as input and returns User Profile Response. Spring Web Services takes care about all boiler-plate code and allows to concentrate on what really matters - implementation. Aside from very basic features, Spring Web Services allows to configure response/request validation (against XSD schema). Inspired by the Spring Web Services project (see Spring WS), the Spring Web Services (WS) plugin support the provision and consumption of best practice, contract-first web services in your Grails applications.For more on why contract-first web services are considered a best practice, see in why contract first .
To override the default endpoint payload mapping strategy, all you have to do is provide the request Element static property that contains the name of the element you expect in the root of the documents that you want to route to your endpoint: WS-Security is the standard mechanism for providing secure web services.By convention, an endpoint is routed all documents that have a root payload element that marches the endpoint's name, without the Endpoint bit, and in the indicated namespace.As of version 0.2.2 you can now override this default behaviour an indicate a specific element name for the incoming request document.NOTE: As of 0.2.3 the Spring WS plugin does not come packaged with the Functional Test plugin.This was due to problems with packaging the plugin into a war when it depended on plugins that only had 'test' scope.

Unfortunately, contract first web services have a, largely undeserved, reputation for being a touch tricky to implement, however this plugin intends to make it as easy as possible to employ these best practices.
