为什么有两种方法来处理Spring中的静态资源（addResourceHandlers和容器的默认Servlet）

①

  @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        LOGGER.debug("configureDefaultServletHandling");
        configurer.enable();
    }

②

@Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/**").addResourceLocations( "/static/");
    }
