Answer 1

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

Spring doc

So,

extends HandlerInterceptorAdapter -> implements HandlerInterceptor

the link is dead, I'm upgrading from srpring-boot 2.1.2 to 3.0.1 and bumping into issues importing org.springframework.web.servlet.handler.HandlerInterceptorAdapter – Fundamentalism

Answer 2

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- https://docs.spring.io/spring-framework/docs/5.3.9/javadoc-api/org/springframework/web/servlet/HandlerInterceptor.html

Use instead

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

Answer 3

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.
