As setting the url via application.properties is not supported with the current release (2.0.4) i had to implement a Workaround until this PR get merged and release.

With this change it will be possible to set the api-docs url in the config without activating QueryConfig to be able to load the api-docs directly on loading the swagger ui.

HotFix/Workaroung:

springdoc: swagger-ui: disable-swagger-default-url: true

@Bean @Primary @ConditionalOnMissingBean @Lazy(false) SwaggerIndexTransformer indexPageTransformer(SwaggerUiConfigProperties swaggerUiConfig, SwaggerUiOAuthProperties swaggerUiOAuthProperties, SwaggerUiConfigParameters swaggerUiConfigParameters, SwaggerWelcomeCommon swaggerWelcomeCommon, ObjectMapperProvider objectMapperProvider) { return new FixingSwaggerIndexTransformer(swaggerUiConfig, swaggerUiOAuthProperties, swaggerUiConfigParameters, swaggerWelcomeCommon, objectMapperProvider); }

`
public class FixingSwaggerIndexTransformer extends SwaggerIndexPageTransformer {
/**
* Instantiates a new Swagger index transformer.
*
* @param swaggerUiConfig the swagger ui config
* @param swaggerUiOAuthProperties the swagger ui o auth properties
* @param swaggerUiConfigParameters the swagger ui config parameters
* @param swaggerWelcomeCommon the swagger welcome common
* @param objectMapperProvider the object mapper provider
*/
public FixingSwaggerIndexTransformer(SwaggerUiConfigProperties swaggerUiConfig, SwaggerUiOAuthProperties swaggerUiOAuthProperties,
SwaggerUiConfigParameters swaggerUiConfigParameters, SwaggerWelcomeCommon swaggerWelcomeCommon, ObjectMapperProvider objectMapperProvider) {
super(swaggerUiConfig, swaggerUiOAuthProperties, swaggerUiConfigParameters, swaggerWelcomeCommon, objectMapperProvider);
}

@Override
protected String overwriteSwaggerDefaultUrl(String html) {
    return html.replace(Constants.SWAGGER_UI_DEFAULT_URL, swaggerUiConfig.getUrl());
}

}
