srping boot的web项目，添加登录拦截器后，页面样式文件消失了，怎么办？

[procedure123]

@Configuration
public class MyMvcConfig extends WebMvcConfigurerAdapter {

    @Bean //将组件注册在容器
    public WebMvcConfigurerAdapter webMvcConfigurerAdapter(){
        WebMvcConfigurerAdapter adapter = new WebMvcConfigurerAdapter() {
         

            //注册拦截器
            @Override
            public void addInterceptors(InterceptorRegistry registry) {
                //super.addInterceptors(registry);

               registry.addInterceptor(new LoginHandlerInterceptor()).addPathPatterns("/**")
                        .excludePathPatterns("/","/admininfo/login");
            }
        };
        return adapter;
    }

}

如上述代码，添加了一个mvc配置类，并注册了一个登录拦截器。然后不经过登录页面直接访问数据展示页面，页面的CSS样式消失了，如果规规矩矩的从登录页进入系统，CSS样式还是正常。这是什么原因？
拦截器定义如下

public class LoginHandlerInterceptor implements HandlerInterceptor {
    //目标方法执行之前
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        Object user = request.getSession().getAttribute("name");
        if(user == null){
            //未登陆，返回登陆页面

            request.getRequestDispatcher("/").forward(request,response);
            return false;
        }else{
            //已登陆，放行请求
            return true;
        }

    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {

    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {

    }
}

.excludePathPatterns("/","/admininfo/login", "/static/**");

因为你拦截了css，js，你得放行静态资源。
