WebMvcConfigurationSupport 拦截器失效

Question

class WebMvcConfig extends WebMvcConfigurationSupport {

@Override
protected void addInterceptors(InterceptorRegistry registry) {

    registry.addInterceptor(new SecurityIntercepter(ac)).excludePathPatterns("/tokens").addPathPatterns("/**");
    super.addInterceptors(registry);
}

}
这里面添加拦截器，拦截不到url。请问原因

使用的是xml零配置之WebMvcConfigurationSupport，也就是相当于MVC的配置文件。里面重写了addInterceptors。
