[Rest] How to unmarshall objects in controller?

[leadpumper]

Hello everyone,

In the ItemsController (with @Controller annotation) I have a method with the @RequestMapping(value="/items", method=RequestMethod.GET) annotation. It adds an attribute to a Model and returns a view name. This view is a org.springframework.web.servlet.view.xml.Marshalli ngView with the marshaller property set to a org.springframework.oxm.jaxb.Jaxb2Marshaller. This all works fine.

Now for the RequestMethod.POST part. In the same controller I have a method public String post(RestItem restItem) with the @RequestMapping(value="/items", method=RequestMethod.POST) annotation.

The restItem is sent by the client but not unmarshalled before calling the controller. It's properties are all null. This makes sense, I didn't configure an unmarshaller equivalent of org.springframework.oxm.jaxb.Jaxb2Marshaller anywhere.

Where do I configure this?? What property to set? Or do I need to unmarshall myself?

With kind regards,

Jurrie

Don't you just hate it when you get your answer just after posting to a forum?

The answer is to read the documentation: Spring Reference 15.3.2.5 Mapping the request body with the @RequestBody annotation

In short: configure a org.springframework.web.servlet.mvc.annotation.Ann otationMethodHandlerAdapter and set its messageConverters property to contain a org.springframework.http.converter.xml.Marshalling HttpMessageConverter with your marshaller and unmarshaller. Then your @RequestBody annotation magically works
