我尝试在tomcat本地服务器上使用spring框架编写我的网站。我尝试添加css到我的html文件。Css文件似乎被链接到服务器上，但devtools显示它是空的。你知道我会错过什么吗?
EDIST很抱歉发了照片，下次我会知道的。我留下了我想显示的最小值。

文件结构devtools on server, index.css view
您在/WEB-INF/css文件夹中的静态资源不是由Spring提供的，因此对http://example.com/app/css/index.css的请求返回404错误。
需要修改addResourceHandlers方法:
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/files/**")
.addResourceLocations("/WEB-INF/pdf/");
registry.addResourceHandler("/css/**")
.addResourceLocations("/WEB-INF/css/");
}
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/**")
.addResourceLocations("classpath:/META-INF/resources/", "classpath:/resources/", "classpath:/static/", "classpath:/public/", "/");
}
