Estoy tratando de configurar hibernatebundle con guice / dropwizard y necesito ayuda. Estoy usandohubspot / dropwizard-guice / 0.7.0 Biblioteca de terceros además de lib libra asistente.

El siguiente código obviamente no funcionará y necesita ayuda para resolverlo. ¿Cómo reescribo esto para que hibernatebundle y, en última instancia, session factory, se inyecte automáticamente a cualquier bean que lo necesite?

MyApplication.java

public class MyApplication extends Application<MyAppConfiguration> {

    private final HibernateBundle<MyAppConfiguration> hibernateBundle = new HibernateBundle<MyAppConfiguration>(MyModel.class) {
        @Override
        public DataSourceFactory getDataSourceFactory(MyAppConfiguration configuration) {
            return configuration.getDataSourceFactory();
        }
    };

    @Override
    public void initialize(Bootstrap<MyAppConfiguration> bootstrap) {
        bootstrap.addBundle(hibernateBundle);  // ???

        bootstrap.addBundle(
            GuiceBundle.<MyAppConfiguration>newBuilder()
                    .addModule(new MyAppModule())
                    .enableAutoConfig(getClass().getPackage().getName())
                    .setConfigClass(MyAppConfiguration.class)
                    .build()
        );
    }

}   

MyAppModule.java

public class MyAppModule extends AbstractModule {

    @Provides
    public SessionFactory provideSessionFactory(MyAppConfiguration configuration) {
            // really wrong as it creates new instance everytime.
        return configuration.getHibernateBundle().getSessionFactory(); // ???
    }

}

MyAppConfiguration.java

public class MyAppConfiguration extends Configuration {
    @Valid
    @NotNull
    private DataSourceFactory database = new DataSourceFactory();

    @JsonProperty("database")
    public DataSourceFactory getDataSourceFactory() {
        return database;
    }

    @JsonProperty("database")
    public void setDataSourceFactory(DataSourceFactory dataSourceFactory) {
        this.database = dataSourceFactory;
    }

        // ???
    public HibernateBundle<MyAppConfiguration> getHibernateBundle() {
        return new HibernateBundle<MyAppConfiguration>(MyModel.class) {
            @Override
            public DataSourceFactory getDataSourceFactory(MyAppConfiguration configuration) {
                return database;
            }
        };
    }

}
