How can I not have to search for a user every time in Spring?

Question

Java

In general, every time I access a controller in Spring, I have to look for a user, create an object, and already work with it. Those. let's say I go to /profile, I pull out the name of the authorized user, I look for it in the Base, if everything is fine, then I work with it. I click on /index, then again I have to look for the user in the database, create an object and again build a page for it. How to avoid searching and creating a new object?

If you are using Spring Security, then the current authorized user is in the SecurityContextHolder, we get it like this:

(UserWrapper) SecurityContextHolder.getContext().getAuthentication().getPrincipal()
