My configuration looks like this:

& lt; dependency & gt;
      & Lt; groupId & gt; io.springfox & lt; / groupId & gt;
      & Lt; artifactId & gt; springfox-swagger-ui & lt; / artifactId & gt;

      & Lt; scope & gt; compile & lt; / scope & gt;
    & lt; / dependency & gt;
//P.S. & Lt; swagger.docs.version & gt; 2.9.2 & lt; /swagger.docs.version>

@ Configuration

  @Bean

    return new BCryptPasswordEncoder (12);
  }
  @Override

    resolvers.add (new AuthenticationPrincipalArgumentResolver ());
  }

}

According to the documentation, bean and dependency pom enough, but when I turn on the link localhost: 8080 / swagger-ui.html does not show anything ((

The security config I pointed antMathers ( "/ swagger-ui.html") permitAll ();.

This is what comes out:

As you can see from the screenshots, let me in the country, but the page is completely blank

(All controllers on the spot)

UPD : / v2 / api-docs work, give json

Do not operate the following URLs (404):

app_root / v2 / swagger-ui /
app_root / swagger-ui /

Chtosh)

allow URL /swagger-ui.html was not enough. That’s what decided my question:

@ Override
  public void configure (WebSecurity web) throws Exception {
    web.ignoring (). antMatchers ( "/ v2 / api-docs",
        "/ Configuration / ui",
        "/ Swagger-resources / **",
        "/ Configuration / security",
        "/Swagger-ui.html",
        "/ Webjars / **");
  }

it I overdered in the SpringSecurity config and everything worked

Answer 2, Authority 67%

I have in one of the projects /swagger-ui.html did not work because of the dependence

& lt; dependency & gt;
  & lt; groupid & gt; org.apache.tomcat.Embed & lt; / groupid & gt;
  & lt; artifactid & gt; Tomcat-Embed-Jasper & lt; / artifactid & gt;
  & lt; scope & gt; compile & lt; / scope & gt;
& lt; / dependency & gt;

If it is not possible to fix it, you can download Swagger UI and download it as static files (https://github.com/swagger-api/swagger-ui/release/tag/v3.47.1 Directory Dist )

But generally I recommend to watch OpenAPI
