A simple EDSL (Embedded Domain-Specific Language) for configuring the Apache CXF implementation of JSR-311.
Provides a configured JAXRSServerFactoryBean instance that you can use to start a Server in any particular way you need.
Resources and providers will be created with Guice, then they will have the normal CXF/JAX-RS injections performed on them.
Example:
protected void configure() {
serve().atAddress("/rest");
publish(LibraryResource.class);
readAndWriteBody(JAXBElementProvider.class);
readAndWriteBody(JSONProvider.class);
mapExceptions(ApplicationExceptionMapper.class);
}guice-cxf supports injecting Jax-Rs resource with dependencies bound in Guice.
@Path("foo");
public class LibraryResource {
@Inject private BookService service;
@GET
public Books search(@QueryParam("q") String q){
return service.findBooks(q);
}
// [...]
}You can also enable injecting sub-resources instead of creating them manually;
protected void configure(){
bind(BookResource.class).in(REQUEST);
}@Path("foo");
public class LibraryResource {
// [...]
@Injected
@Path("{id}")
public BookResource getBook(@PathParam("id") String id){
throw new UnsupportedOperationException("will be implemented by Guice");
}
}Finally you can inject @Context dependencies (HttpHeaders, Request, UriInfo etc.), provided you are in appropriate scope (there is a special REQUEST scope provided for Jax-Rs requets).
public class BookTitleResolver {
@Inject
private HttpHeaders headers;
public String resolveTitleFor(String id){
return getBook(id).getTitleForLanguage(headers.getLanguage());
}
// [...]
}To create a server do:
injector.getInstance(JAXRSServerFactoryBean.class).create();The current version is well tested and working, although not all CXF features can be configured yet (you can always set them on the provided JAXRSServerFactoryBean instance).
See the Features page for a more complete list.
