spring5，ViewResolver 怎么排除其他资源如html

开源之夏第三届火热来袭，高校学生参与赢万元奖金！>>>

web项目里，页面用fk，ViewResolver配置了fk的后缀，但是还另外想访问html资源，该如何配置。

@Bean
public ViewResolver viewResolver(){
   InternalResourceViewResolver resolver = new InternalResourceViewResolver();
   resolver.setPrefix("/WEB-INF/");
   resolver.setSuffix(".ftl");
   resolver.setExposeContextBeansAsAttributes(true);
   return resolver;
}

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
   registry.addResourceHandler("/statics/**").addResourceLocations("/WEB-INF/statics/");
}

@RequestMapping
public String index(){
   return "statics/index.html";
}

上面配置之后，再访问statics/下的xx.html文件实际会被解析成xx.html.ftl ,还需要怎么配置才能正常访问html文件呢
