JAX-RS: OPTIONS for every Resource
ajax, java, jax-rs, jersey
Solution
UPDATE 09/12/2013: THIS DOES NOT WORK. Using this all @GET/@DELETE/@POST/@PUT are not working any more.
Finally I solved my problem. I created a super class `OptionsResource`, from which all resources inherit. This resoruce contains:
// Match root-resources
@OPTIONS
@PermitAll
public Response options() {
return Response.status(Response.Status.NO_CONTENT).build();
}
// Match sub-resources
@OPTIONS
@Path("{path:.*}")
@PermitAll
public Response optionsAll(@PathParam("path") String path) {
return Response.status(Response.Status.NO_CONTENT).build();
}
An example:
@Path("/test")
public class TestResource extends OptionsResource {
@GET
@Produces("text/plain;charset=UTF-8")
public Response index() {
return Response.status(Status.OK).entity("works").build();
}
}
This matches:
- curl -I -X OPTIONS http://myhost.com/test
- curl -I -X OPTIONS http://myhost.com/test/asd/aasd/12/
- etc.
Problem
I am using a JAX-RS interface with XMLHttpRequest (XHR). Due to the XHR preflight, XHR send always OPTIONS before calling the real resource. Now I have dozens of methods and I need the OPTIONS for every resoruce. Is there any way to do this automatically? I dont want to write dozens of methods like: ``` @OPTIONS @Path("/{id}") @PermitAll public Response optionsById() { return Response.status(Response.Status.NO_CONTENT).build(); } @OPTIONS @Path("/{id}/data") @PermitAll public Response optionsByData() { return Response.status(Response.Status.NO_CONTENT).build(); } ```
