在进行springboot的web项目实战,在添加登陆拦截器之前，前台页面样式引用是好的，添加之后css样式加载不到了。
解决报错的方法：分别放开对报错静态资源的拦截
报错拦截器代码

@Bean
    public WebMvcConfigurer webMvcConfigurer() {
        WebMvcConfigurer wmc = new WebMvcConfigurer() {
            @Override
            public void addViewControllers(ViewControllerRegistry registry) {
                registry.addViewController("/").setViewName("index");
                registry.addViewController("/index.html").setViewName("index");
                registry.addViewController("/main.html").setViewName("dashboard");
                }
                //注册拦截器
            @Override
            public void addInterceptors(InterceptorRegistry registry) {
                //静态资源*.css,*.js，因springboot已经做好资源映射，所以无需处理静态资源
                registry.addInterceptor(new LoginHandlerInterceptor()).addPathPatterns("/**")
                        .excludePathPatterns("/index.html","/user/login","/");
            }
        };
        return wmc;

正确拦截器代码：

@Bean
    public WebMvcConfigurer webMvcConfigurer() {
        WebMvcConfigurer wmc = new WebMvcConfigurer() {
            @Override
            public void addViewControllers(ViewControllerRegistry registry) {
                registry.addViewController("/").setViewName("index");
                registry.addViewController("/index.html").setViewName("index");
                registry.addViewController("/main.html").setViewName("dashboard");
                }
                //注册拦截器
            @Override
            public void addInterceptors(InterceptorRegistry registry) {
                //静态资源*.css,*.js，因springboot已经做好资源映射，所以无需处理静态资源，注意放开报错的静态资源
                registry.addInterceptor(new LoginHandlerInterceptor()).addPathPatterns("/**")
                        .excludePathPatterns("/index.html","/user/login","/","/webjars/**","/img/**","/**/*.css","/**/*.svg");
            }
        };
        return wmc;
