Thank you for the clean tutorial.
In the third option when i did the following

@Autowired
VehicleService vehicleService;

I get this error:
Could not autowire. There is more than one bean of 'VehicleService' type.
Beans:
(AppConfiguration.java)
(AppConfiguration.java)

Thanks for this wonderful tutorial. Is there any way to load values directly from properties and internally added to DTO getter / setter methods?

[MiguelRomero-djxq]

Its all good man, great tutorial. Another topic would be spring security

[itlearner]

Thank you for such a good tutorial. Just a small question, how would you do if there is a parametrised constructor in VehicleTestService instead of @Autowired? thanks!

[ДимитърРусков]

Great tutorial, but please increase the font size of the IDE!

[surajdhembre]

can we always replace qualifier with conditionalonproperty annotation?

[Runnable]

Have you thought to make a really good udemy course on spring and spring boot ?

[TESkyrimizer]

Honestly man I keep looking into this and it talks about reducing coupling but I still don't get why all these extra steps are necessary. Is there a for dummies version available i am dying

[surajdhembre]

can you tell me the difference between Qualifier and ConditionalOnProoperty please

[shadabmohammad]

When ur explaining you should zoom in into intellij or increase font size

[susanthkakarla]

isn't it easier to use primary instead of making qualifier?

[alxdm]

very small screen, please zoom nxt time
