我只是迁移到Spring 5.0.1.RELEASEMVC 版本，但突然在Eclipse STS中将WebMvcConfigurerAdapter标记为已弃用

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/");
    }
  ....
  }

我该如何删除！
