Springfox swagger-ui.html unable to infer base URL - Caused by missing cookies

Add in the security config -- following URLS that are skipped for authentication ::

private static final String[] AUTH_WHITELIST = {        "/swagger-resources/**",        "/swagger-ui.html",        "/v2/api-docs",        "/webjars/**"};@Overridepublic void configure(WebSecurity web) throws Exception {    web.ignoring().antMatchers(AUTH_WHITELIST);}

Adding below annotation at the spring boot class resolved this issue for me.

@EnableSwagger2

I am using swagger version

 <version>2.9.2</version>

SEE EDIT BELOW

Do you use spring security?

If yes, probably you skip some resources like this (right?):"/swagger-resources/**","/swagger-ui.html","/v2/api-docs","/webjars/**"

Try to change it "/swagger-resources/**" to "**/swagger-resources/**".

My specific security config for swagger is:

private static final String[] AUTH_LIST = {        // -- swagger ui        "**/swagger-resources/**",        "/swagger-ui.html",        "/v2/api-docs",        "/webjars/**"};@Overrideprotected void configure(HttpSecurity http) throws Exception {    http    .authorizeRequests().antMatchers(AUTH_LIST).authenticated()    .and()    .httpBasic().authenticationEntryPoint(swaggerAuthenticationEntryPoint())    .and()    .csrf().disable();}@Beanpublic BasicAuthenticationEntryPoint swaggerAuthenticationEntryPoint() {    BasicAuthenticationEntryPoint entryPoint = new BasicAuthenticationEntryPoint();    entryPoint.setRealmName("Swagger Realm");    return entryPoint;}

If you need/want I can send a sample project to GitHub to you know more about my security/swagger configs.

EDIT 2018/04/10

This problem is caused by a wrong version in springfox. See this issue on github to solve the problem.
