我在这里问了一个关于最新spring框架,基于代码的配置的问题

初始化

public class AppInitializer extends
        AbstractAnnotationConfigDispatcherServletInitializer {

    public class MvcConfig extends WebMvcConfigurerAdapter {
        @Bean
        public InternalResourceViewResolver viewResolver() {
            InternalResourceViewResolver resolver = new InternalResourceViewResolver();
            resolver.setPrefix("/WEB-INF/jsp/");
            resolver.setSuffix(".jsp");
            return resolver;
        }

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