Spring @Configuration Annotation - What are Proxy Bean Methods?

In this tutorial, you will learn about a property of the @Configuration annotation proxyBeanMethods. This property is set to true by default but as you will learn there are situations where you might want to set this to false.

Great insight! Even though we cannot make this behaviour default, it *feels* like it should be default. Personally I’m against any “magic” in code. I like things concise and transparent and I don’t mind writing a little more code instead of using the “magic.”

I always wondered about this but didn't dig much. Thanks for making it clear!

[MisterJuviva]

The explanation is clear.
You made a small typing error in the description @Configuration :)
Thank you for the tutorial !

It's really useful information. FYI - Spring uses its own folk of CGLIB within spring-core.

So cool, thanks for the video!
So, what was the decision to introduce the proxies in the past?
Is it considered to be a bad practice now?
What are the situations when we cannot avoid proxies?

[urisimchoni]

One thing I don't get - The CGLib proxy installs a wrapper around the conf class, but doesn't modify the class itself (or so we're told in the Spring-AOP documentation, maybe I'm mixing two use cases for CGLib). So when we call restTemplate() from runService(), how does Spring make us go through the proxy (in comparison, the AOP docs specifically indicate that calls from one method of the class to another aren't being proxied)?

thanks! great tutorial. Dan why you don't ever use Lombok in your videos? Is it for a better understanding of what's going on? Or it is bcoz some annotations don't work well with Spring? (IDEA sometimes suggests me avoid @Data for entities)

[IvanRandomDude]

Maybe proxyBeanMethods should be set to false by default and then give us warning to enable it if we use bean methods inside config class. If in fact it can improve performance....

Thanks for the cool insight!!!. If possible can you come up with @Transactional annotation specially with R2DBC. Thanks once again.

Why don't u use the intellij itself to initialize an spring boot project? It also adds dependencies automatically. Everything in intelij 🎉

Can you make a video where a user cannot view and edit information of another user even when they have same role and authority using spring security and a relational database … I looked at many YouTube channels but they also haven’t showed it .. Can you please make a video ? Thank you so very much !

[marouaniAymen]

Thanks, I learned something new. But I noticed that the appearance of IntelliJ is different from the classic, is it a new version or a theme ?

[vipinkoul]

Nice tutorial. As you were mentioning of "native..", could you please elaborate what does it mean in the context of this tutorial or where it's applicable ? what does it actually mean, like by flipping flag proxyBeanMethods to false does it mean the "code" would run natively, what does it mean?

Question about @Bean public methods. Does IntelliJ not offer to remove the public modifier? Both Spring Tool Suite and the OpenRewrite best practices recipe will remove it, for reference:

Remove public modifier from @Bean methods. They no longer have to be public visibility to be usable by Spring.
