Springboot2.1.1下的自定义拦截器而静态资源不能访问的问题

1.项目结构

2.自定义拦截器

public class LoginHandlerlnterceptor implements HandlerInterceptor {
    //目标方法执行之前
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        Object loginname = request.getSession().getAttribute("loginname");
        if(loginname==null||loginname.equals("")){
            //未登录，返回登陆界面
            request.setAttribute("msg","没有权限，请先登陆");
            //返回登陆page并且相应
           // response.sendRedirect("/index.html");
            request.getRequestDispatcher("/").forward(request,response);
            return false;
        }else
        {
            //已经登陆,放行
            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 {

    }
}

3.拦截器加入mvc

public class Mymvc implements WebMvcConfigurer {
    //注册拦截器
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        //springboot1已经做好了静态资源映射了，可以访问到
        registry.addInterceptor(new LoginHandlerlnterceptor()).addPathPatterns("/**").excludePathPatterns("/", "/user/logins", "/login.html").excludePathPatterns("/img/**",
                "/css/**", "/webjars/**");
    }

}
