Spring Boot AOP Code Review Java

This might be a silly question, but Currently developing a Spring Boot application where code reviews are pivotal for maintaining quality... During our last review, it was pointed out that our use of annotations for validation might not be optimal. We’ve used `@Valid` along with custom validators, but feedback suggested that we explore how to leverage Aspect-Oriented Programming (AOP) to handle validation more effectively. Here’s a snippet of our current implementation: ```java @RestController public class UserController { @PostMapping("/users") public ResponseEntity<User> createUser(@Valid @RequestBody User user) { // logic to save user } } ``` The idea is to add a layer that intercepts requests before they hit the controller, which could streamline our validation process. Additionally, I’ve come across mentions of using custom filters to manage cross-cutting concerns like logging and error handling. I started experimenting with a simple filter: ```java @Component public class RequestLoggingFilter implements Filter { @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { // Log request details chain.doFilter(request, response); } } ``` The challenge arises with how to combine these two strategies without complicating the flow or making it less readable. Community recommendations point to best practices that suggest keeping the controller thin, but I’m unsure how far to go with this. Would implementing AOP for validation and using filters simultaneously hinder performance? Are there any specific pitfalls to be aware of? Any insights on balancing code readability with a clean architecture would be greatly appreciated. I’m using Spring Boot version 2.5.4 and looking for ways to enhance our review process without sacrificing maintainability. I'd really appreciate any guidance on this. How would you solve this?
