swagger2的页面报错：Unable to infer base url…

和spring-security配置有关

解决办法：.antMatchers(“/v2/api-docs”, “/configuration/ui”, “/swagger-resources”, “/configuration/security”, “/swagger-ui.html”, “/webjars/**”,”/swagger-resources/configuration/ui”,”/swagge‌​r-ui.html”).permitAl‌​l()

1，问题的思考，是否是有还有其它的配置请求进行拦截；检查配置。

2，登录的拦截器；

3，MVC中的messageConverts;
