How to inject a DAO class (component) into REST resource filter Edited

[Vikash Kumar]

I am writing a REST filter for one my rest api class. I want to do authorization in the rest filter and annotate all the REST services I need to apply authorization check on. Here's the Rest Resource Filter code:

@Scanned
@Component
public class AuthorizationFilter implements ResourceFilter {

 private MyActibeObjectDao myActibeObjectDao;
 
 @Inject
 public AuthorizationFilter(MyActibeObjectDao myActibeObjectDao) {
    this.myActibeObjectDao = myActibeObjectDao;
 }

 
 @Override
 public ContainerRequestFilter getRequestFilter() {
 
   return new ContainerRequestFilter() {
    @Override
    public ContainerRequest filter(ContainerRequest request) {
      ...
      /* Fetch admin users from AO */
      String[] admins = myActibeObjectDao.getAdminUsers();
      /* If not in the admins then throw Exception */
      throw new WebApplicationException(
             Response.status(Response.Status.FORBIDDEN)
             .entity("You are not authorized to this operation!")
             .build());
    }
  };
 }

...
 
}

Here's my REST class:

 @GET
 @AnonymousAllowed
 @Produces(MediaType.APPLICATION_JSON)
 @Path("/settings/{userId}")
 @ResourceFilters(AuthorizationFilter.class)
 public Response retrieveTableMetaData(@PathParam("userId") Integer userId) {
 /* To Do: */

} 

The problem is, I am getting null value in 

myActibeObjectDao

Any pointer will be of great help in this regards.

Thank you!
