对于html文件的处理在启动类增加InternalResourceViewResolver 视图解析
    @SpringBootApplication
    @EnableWebMvc
    @EnableRabbit
    public class MallPortalApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(MallPortalApplication.class, args);
        }
    
        @Bean
        public InternalResourceViewResolver setupViewResolver(){
            InternalResourceViewResolver resolver = new InternalResourceViewResolver();
            resolver.setPrefix("/templates/");
            resolver.setSuffix(".html");
            return resolver;
    
        }
    
    }

对于静态文件的处理是增加如下配置实现WebMvcConfigurer 类
    
    @Configuration
    @EnableWebMvc
    public class MvcConfig implements WebMvcConfigurer {
        @Override
        public void addArgumentResolvers(List<HandlerMethodArgumentResolver> resolvers) {
            resolvers.add(new PageArgumentResolver());
        }
    
        /**
         *  视图跳转控制器
         * 无业务逻辑的跳转 均可以以这种方法写在这里
         * @param registry
         */
        public void addViewControllers(ViewControllerRegistry registry) {
            registry.addViewController("/index").setViewName("index");
        }
    
    //最主要的是在这里
        @Override
        public void addResourceHandlers(ResourceHandlerRegistry registry) {
    
            //告知系统static 当成 静态资源访问
            registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/");
            registry.addResourceHandler("/preview/static/**").addResourceLocations("classpath:/static/");
        }
    }
