经多方查找，是在登录拦截器把所有的请求都拦截过滤掉了，导致swagger的静态资源访问不了;

解决

把swagger的静态资源解除拦截：

.excludePathPatterns("/swagger-resources/**", "/swagger-ui.html/**");
@Override
public void addInterceptors(InterceptorRegistry registry) {
    registry.addInterceptor(loginInterceptor).addPathPatterns("/**")
            .excludePathPatterns("/swagger-resources/**", "/swagger-ui.html/**");
}

总结

以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
