Swagger2 UI Resource mapping and API Documentation is missing

1.5k Views Asked by At

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: [email protected]

And finally this is a log from my application when I launch swagger2 html page http://localhost:8080/swagger-ui.html#/

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.
