401 unauthorized page for swagger?

I am enable swagger2 by @EnableSwagger2. However, when I try to hit "/swagger-ui.html", it first hit my Authentication Filter. Then, I wrote the following code to bypass the authentication check

String resourcePath = new UrlPathHelper().getPathWithinApplication(httpRequest);
if ("/swagger-ui.html".equalsIgnoreCase(resourcePath)) {
     filterChain.doFilter(request, response);
}

I can see the filterChain.doFilter(request, response); was hit. However, when I let the debug go, it returns a page with information below

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Unauthorized, status=401).
No message available

Any idea, guys?

I had same problem in my project then, first add config file into project

package bla.bla.conf;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class Swagger2Config {
    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2).select()
                .apis(RequestHandlerSelectors
                        .basePackage("bla.bla.controllers"))
                .paths(PathSelectors.any())
                .build();
    }

}

and add this code block to you WebSecurityConfig

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().mvcMatchers(HttpMethod.OPTIONS, "/**");
    web.ignoring().mvcMatchers("/swagger-ui.html/**", "/configuration/**", "/swagger-resources/**", "/v2/api-docs","/webjars/**");
}

my problem fixed

Think you can add your ownWebSecurityConfig extends WebSecurityConfigurerAdapter, than override configure(WebSecurity web) method and there put web.ignoring().antMatchers("/swagger-ui.html") ofc annotate that class with @Configuration

I have the same error and I add this code inside the class websecurityConfig

 @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.cors().and().csrf().disable()
                .exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
                .authorizeRequests().antMatchers("/api/auth/**").permitAll() 
                .antMatchers("/api/test/**").permitAll() // permit the class of test
                .antMatchers("/**").permitAll() // permit all the routers after swagger-ui.html
                .anyRequest().authenticated();

        http.addFilterBefore(authenticationJwtTokenFilter(), UsernamePasswordAuthenticationFilter.class);
    }
