Swagger2 UI Resource mapping and API Documentation is missing - spring

Question

This is a Spring Boot project.
I have added Spring Fox a Swagger 2 based API documentation tool to my .pom file and I have
configured it but for some reason (my guess is the resource mapping is not working properly)
The basic part of the confguration is there but when I have added more specific configuration,
like my contact or description of the API -> this part is not showing.
This is my Swagger configuration class:
#Component
#PropertySource("classpath:springFoxdocumentation.yml")
#EnableSwagger2
#EnableWebMvc
public class SpringFoxConfig implements WebMvcConfigurer {
#Value("${api.common.version}")
private static String apiVersion;
#Value("${api.common.title}")
private static String apiTitle;
#Value("${api.common.description}")
private static String apiDescription;
#Value("${api.common.termsOfServiceUrl}")
private static String apiTermsOfServiceUrl;
#Value("${api.common.license}")
private static String apiLicense;
#Value("${api.common.licenseUrl}")
private static String apiLicenseUrl;
#Value("${api.common.contact.name}")
private static String apiContactName;
#Value("${api.common.contact.url}")
private static String apiContactUrl;
#Value("${api.common.contact.email}")
private static String apiContactEmail;
#Bean
public Docket apiDocumentation(){
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(RequestHandlerSelectors.any())
.paths(PathSelectors.any())
.build()
.globalResponseMessage(RequestMethod.GET, Collections.emptyList())
.apiInfo(new ApiInfo(
apiVersion,
apiTitle,
apiDescription,
apiTermsOfServiceUrl,
new Contact( apiContactName, apiContactUrl,apiContactEmail),
apiLicense,
apiLicenseUrl,
Collections.emptyList()
));
}
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("swagger-ui.html")
.addResourceLocations("classpath:/META-INF/resources/");
registry.addResourceHandler("/webjars/**")
.addResourceLocations("classpath:/META-INF/resources/webjars/");
}
}
I know that I shouldn't have there the resource handler method, but since I have assumed that this problem is caused by resource mapper I have added it int the code (but it didn't help)
And this is my .yml file under resources folder
api:
common:
version: 1.0.0
title: Ticket Manager
description: Ticket Manager server as a simple REST API for managing ticket and Incidents
termsOfServiceUrl: LINK FOR TERMS OF SERVICE
license: This is a Open Source Licensed product
licenseUrl: LINK FOR LICENSE URL
contact:
name: opensourcedev
url: URL FOR OPENSOURCEDEV
email: sample#gmail.com
And finally this is a log from my application when I launch swagger2 html page http://localhost:8080/swagger-ui.html#/

Answer 1

There are two issues in your code. First of all, #Value does not work on static fields. So all your springfox declared fields are null. Spring never set values in them.
If you remove the static from your fields , Spring will tell you that it doesn't find the properties like api.common.version or api.common.title. Because #PropertySource does not load yml files. It is declared in official documentation.
But there are workaround, you can follow this source here to use yml files with #PropertySource.
