How to change basePath for Springfox Swagger 2.0

Question

I'm running a service, where Swagger UI is accessible at:

http://serviceURL/swagger-ui.html

However, it is behind a proxy, such as:

http://proxyURL/serviceName

Generated URLs by Swagger UI are looking like:

http://proxyURL/

instead of the actual URL with the serviceName as suffix. As far as I get it, this means manipulating the basePath property. As per documentation:

A swagger API documentation can no longer describe operations on different base paths. In 1.2 and earlier, each resource could have had a separate basePath. In 2.0, the basePath equivalents (schemes+host+basePath) are defined for the whole specification.

@Api(basePath) is deprecated, and it doesn't say what to use and how to use it. How to make the paths generated by Swagger appear properly?

I'm using Spring Boot, Springfox Swagger and annotations.

@Bean
public Docket newsApi(ServletContext servletContext) {
    return new Docket(DocumentationType.SWAGGER_2).pathProvider(new RelativePathProvider(servletContext) {
        @Override
        public String getApplicationBasePath() {
            return "/serviceName" + super.getApplicationBasePath();
        }
    }).host("proxyURL");
}
