今天在学习Spring Boot 的时候发现了这样一个问题，当我登录的时候发现页面的样式没有了，一开始不知所措，揭下来慢慢寻找问题的所在，想了想是不是静态资源被拦截了，于是我修改了以下代码
修改之前:
//注册拦截器
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new LoginHandlerInterceptor()).addPathPatterns("/**")
.excludePathPatterns("/","/login.html","/user/login");
}
修改之后:
//注册拦截器
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new LoginHandlerInterceptor()).addPathPatterns("/**")
.excludePathPatterns("/","/login.html","/user/login","/asserts/**","/webjars/**");
}
页面的样式恢复了
