Yeah, they're a little bit annoying, you'll need the jakarta.annotation dependency.
Not that preferably you won't need these annotations at all.
If you really need to close a resource as the component shuts down, okay fine, but it's not that common.
As much as possible, PostConstruct should be replaced by doing it in the constructor, like, during construct.
