For my project I've built a resource and a little set of annotation to
easily expose a REST api which uses JSON as message format. The goal is
to map custom methods to a specific path and extract their parameters
from the URL path or from the request body. For example:
public class TestRestResource extends AbstractRestResource {
/**
* Method invoked for GET requests and URLs like '<resource path>/5'
* The id parameter is automatically extracted from URL
*/
@MethodMapping("{id}")
public void testMethodInt(int id){
....
}
/**
* Method invoked for POST requests and URLs like '<resource path>/5'
* The id parameter is automatically extracted from URL
* The person parameter is automatically deserialized from request
body (which is JSON)
* The returned object is automatically serialized to JSON and
written in the response
*/
@MethodMapping(value = "{id}", httpMethod = HttpMethod.POST)
public Person testMethodPostComplex(int id, @JsonBody Person person){
....
return person;
}
...
I'm porting the code in a public repository here:
https://github.com/bitstorm/Wicket-rest-annotations
I will send a message when I will finish to organize the code.
Right.
The original idea was to create an IRequestHandler that knows how to read
such annotations and execute the proper method of IResource passing the
correct arguments.
But this will take time to implement. So I think it will be easier to just
use your favorite rest library and wrap it in WicketSessionFilter to
provide access to Application and Session thread locals.
