java - The type WebMvcConfigurerAdapter is deprecated

Question

I just migrate to spring mvc version 5.0.1.RELEASE but suddenly in eclipse STS WebMvcConfigurerAdapter is marked as deprecated

public class MvcConfig extends WebMvcConfigurerAdapter {
  @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
        // to serve static .html pages...
        registry.addResourceHandler("/static/**").addResourceLocations("/resources/static/");
    }
  ....
  }

How can i remove this!

Answer 1

Since Spring 5 you just need to implement the interface WebMvcConfigurer:

public class MvcConfig implements WebMvcConfigurer {

This is because Java 8 introduced default methods on interfaces which cover the functionality of the WebMvcConfigurerAdapter class

See here:
