Do you mean you want a service that acts like a "prototype" bean in
Spring? You could create a new scope as Thiago suggests but you are likely
to end up with a service that creates a new underlying object for every
method call - and that probably isn't what you want.
I suggest simply creating a service that is a Factory; maybe something
like this:
public final class AppModule {
public static void bind(ServiceBinder binder) {
binder.bind(ConnectionFactory.class, ConnectionFactoryWithPool.
class);
}
}
public interface ConnectionFactory {
Connection createConnection();
}
public class ConnectionFactoryWithPool implements ConnectionFactory {
....
public Conection createConnection() {
return pool.getConnection();
}
}
public class MyPage {
@Inject
private ConnectionFactory connectionFactory;
public void myAction() {
Connection connection = connectionFactory.createConnection();
try {
...
} finally {
connection.close();
}
}
}
