Using Revolver bundle

Bootstrap

        bootstrap.addBundle(new RevolverBundle<ApiConfiguration>() {

            @Override
            public RevolverConfig getRevolverConfig(ApiConfiguration apiConfiguration) {
                return apiConfiguration.getRevolver();
            }

            @Override
            public PersistenceProvider getPersistenceProvider() {
                return new InMemoryPersistenceProvider();
            }
        });
