Can you make a crash course on Microservices too ? Really love to learn from your experience and way of explaining things. You really inspire me to teach others. Thank you for being there Mr. Vega.

Hi Dan, this is fantastic!! A lot of of these detailed information is hard to be found easily. With most of the tutorials and examples online, they only tell you what/how to do, but not why. Thank you!!

Thank you. Best explanation. I've been hearing those terms and using them, but I never took the time to understand what they mean. Beans put methods in the application context, mostly used with the @Configuration annotation. @Component put classes into the application context. You are awesome!

Nice job. A couple of quick comments: 1. I had no idea that IntellIJ had a Spring view. Seems obvious in retrospect, but thanks for that. 2. I'm surprised you didn't autowire the `RestTemplateBuilder` into the `@Bean` method rather than instantiate it yourself. The builder is available in the application context already, so make it an argument to your configuration method and it'll be autowired in automatically. 3. Even though autowiring works as long as you have only a single constructor in a class, I usually add `@Autowired` anyway, partly as documentation, and partly as protection in case someone else adds a default constructor, at which point the automatic autowiring wouldn't work any more. Just a thought. :)

@Dina-Barbur Жыл бұрын

thank you, Dan! would you please tell about @component vs @repository. Both annotations are used in infrastructure layer of any REST app (storage or repository packages). I'm slightly confused by such diversity.

@FranklyTerrible 5 ай бұрын

Not going to lie, this example about beans only confused me more. How does Spring make that vague connection to the Resttemplate method? That seems like dark magic to me...

@user-zw3kc8qd1z 4 ай бұрын

I have been working on Spring projects and gathered some valuable knowledge! Spring basically has the so-called IoC container, which is associated with the dependency injection system it has been integrated with. In simple words, instead of trying to make new objects with the keyword "new" like "new User();", Spring will automatically inject this dependency for you. This can be done in 3 ways: through field, constructor or setter injection. That's it. Also, by default, the instances provided by spring are singleton, namely, only one instance is provided for the entire application context, which of course can be changed if you want.

@enesb4797 4 ай бұрын

should we not use "new" keyword in classes even if they are just regular classes and not beans or components? let's say I have a helper class for math operations, shouldn't I use "new" keyword in its dependencies? (since you said you should stay away from using "new" keyword 6:54)

@anyname8803 Жыл бұрын

Hello Dan, defining beans with @Bean annotation isn't truly an inversion of control, since we are returning a new bean explicitly with the "new" keyword like so: @Bean public SomeObject myBean(){ return NEW SomeObject() } Please correct my understanding. Thanks

Wait why don't we just make all the methods in Controler and Service static and then we don't need beans for them? I mean why even initialize a Controller class?

spring boot and all that thing of beans are bullshit dude it isn't declarative, I builded an application with jax-rs and it hasn't all this "magic things" of the spring runtime handling all the instances in the limbo, jax-rs (now called jakarta-rs) gives you more freedom.
