As of Spring 5.3 in favor of implementing HandlerInterceptor and/or AsyncHandlerInterceptor directly.

Spring doc

So,

extends HandlerInterceptorAdapter -> implements HandlerInterceptor 

However, Java 8 added the concept of default methods in interfaces. Naturally, the Spring team updated the framework to make full use of the new Java language features. Since Spring 5 with Java 8 baseline allows default methods, the adapter class HandlerInterceptorAdapter is no longer required. Now All the methods defined inside HandlerInterceptor are default methods-

Use instead

public class CustomHandlerInterceptor implements HandlerInterceptor{ // override default methods } 

Earlier - HandlerInterceptor and HandlerInterceptorAdapter In the first one we need to override all three methods: preHandle(), postHandle() and afterCompletion(), In the second we may implement only required methods.

Now in latest version , we can implement directly handlerInterceptor no need of adaptor we may implement only required methods.
