Run code immediately after PersistFilter init.

[ale]

Hello.

I need to run a piece of code immediately after it has run PersistFilter.

The only way is to write my own PersistFilter? Is this a good aproach ?

@Singleton
public final class PersistFilter implements Filter {
  private final UnitOfWork unitOfWork;
  private final PersistService persistService;

  @Inject
  public PersistFilter(UnitOfWork unitOfWork, PersistService persistService) {
    this.unitOfWork = unitOfWork;
    this.persistService = persistService;
  }

  public void init(FilterConfig filterConfig) throws ServletException {
    persistService.start();
   
    service1.start();    // <--- SOMETHING LIKE THIS

    service2.start();
  }
...

Another thought is to use guice's AOP and write a method interceptor for PersistenceService.   Or figure out a way to wrap the persistence service.

I think the real question though is why does it need to initialize RIGHT after?  The answer to this question will likely lead you towards the answer to "how".

I have a service that need information from the database.

PersistentService.start();

TemplateEngineService.start();

...

@Inject TemplateEngine(TemplateDao templateDao) {

}
