creating POJO's as REST parameters

[Scott McMasters <sc...@gmail.com>]

Hello, all,

Is there any way to have Wink automatically create an instance of a POJO
and copy HTTP request parameter values, say, via BeanUtils, to a service
method parameter?

I'm thinking of something like this:

@POST
public void save(MyBean bean)
{
}

Thanks,

Scott McMasters

Hi Scott,

You can absolutely do what your asking.

First, for your MyBean, you want to look into creating custom Providers. You can create a custom provider for MyBean that is created from the request body. You should be able to find that documentation wth some google searches. You can also use the @HeaderParam annotation to get your header values. 

You can reasonably have a classes such as:

@Path(“/test")
public class MyService {

   	@GET
   	@Consumes(MediaType.APPLICATION_JSON)
	public String get(MyBean bean, @HeaderParam("Referer") String referer) {
     		...
   	}
}
@Provider
@Consumes(MediaType.APPLICATION_JSON)
public final class MyBeanProvider implements MessageBodyReader<MyBean>{

	@Override
	public MyBean readFrom(Class<MyBean> type, Type genericType, Annotation[] annotations,
			MediaType mediaType, MultivaluedMap<String, String> headers, InputStream inputStream) throws IOException {

		//Code to build and return MyBean using request input stream

	}


	@Override
	public boolean isReadable(Class<?> type, Type genericType, Annotation[] annotations, MediaType mediaType) {
		return true;
	}


	@Override
	public long getSize(ANFRestResource instance, Class<?> type, Type genericType, Annotation[] annotations,
			MediaType mediaType) {
		return -1;
	}

}


Cheers

Darin
