Debugging Field Injection With NetBeans - Another Reason To Delete Setters 📎
@Stateless
public class LegacyDataSourceConsumer {
@Inject @Legacy
DataSource ds;
}
You can inject resources, EJBs or CDI managed beans directly into fields since Java EE 5 and so for about 5 years. Setters or specific "injector" methods are optional.
With NetBeans you can easily debug the injection with a field breakpoint. You only have to click on the grey bar left the editor to enable a field breakpoint.
You should see a triangle:
By clicking on the triangle and choosing Field Breakpoint -> Properties you can setup additional behavior. The default behavior "Stop On: Field Access Or Modification" is perfect for Dependency Injection debugging. The current thread will stop (probably in a business method) at injection time. So: delete your setters and enjoy Java EE :-).
