Question

I have a Swagger config like this

@EnableSwagger2
@Configuration

    @Bean
    public Docket api() {
        List

        

Answer 1

Support for Authorization: Bearer [JWT_TOKEN] header is working as of version 2.9.2

Added the following dependencies to build.gradle

compile("io.springfox:springfox-swagger2:2.9.2") {
    exclude module: 'mapstruct' // necessary in my case to not end up with multiple mapstruct versions
}
compile "io.springfox:springfox-bean-validators:2.9.2"
compile "io.springfox:springfox-swagger-ui:2.9.2"

Configured Swagger via

@Configuration
@EnableSwagger2
@Import(springfox.bean.validators.configuration.BeanValidatorPluginsConfiguration.class)
public class SwaggerConfiguration {

    public static final String AUTHORIZATION_HEADER = "Authorization";
    public static final String DEFAULT_INCLUDE_PATTERN = "/api/.*";
    private final Logger log = LoggerFactory.getLogger(SwaggerConfiguration.class);

    @Bean
    public Docket swaggerSpringfoxDocket() {
        log.debug("Starting Swagger");
        Contact contact = new Contact(
            "Matyas Albert-Nagy",
            "https://justrocket.de",
            "matyas@justrocket.de");

        List<VendorExtension> vext = new ArrayList<>();
        ApiInfo apiInfo = new ApiInfo(
            "Backend API",
            "This is the best stuff since sliced bread - API",
            "6.6.6",
            "https://justrocket.de",
            contact,
            "MIT",
            "https://justrocket.de",
            vext);

        Docket docket = new Docket(DocumentationType.SWAGGER_2)
            .apiInfo(apiInfo)
            .pathMapping("/")
            .apiInfo(ApiInfo.DEFAULT)
            .forCodeGeneration(true)
            .genericModelSubstitutes(ResponseEntity.class)
            .ignoredParameterTypes(Pageable.class)
            .ignoredParameterTypes(java.sql.Date.class)
            .directModelSubstitute(java.time.LocalDate.class, java.sql.Date.class)
            .directModelSubstitute(java.time.ZonedDateTime.class, Date.class)
            .directModelSubstitute(java.time.LocalDateTime.class, Date.class)
            .securityContexts(Lists.newArrayList(securityContext()))
            .securitySchemes(Lists.newArrayList(apiKey()))
            .useDefaultResponseMessages(false);

        docket = docket.select()
            .paths(regex(DEFAULT_INCLUDE_PATTERN))
            .build();
        watch.stop();
        log.debug("Started Swagger in {} ms", watch.getTotalTimeMillis());
        return docket;
    }


    private ApiKey apiKey() {
        return new ApiKey("JWT", AUTHORIZATION_HEADER, "header");
    }

    private SecurityContext securityContext() {
        return SecurityContext.builder()
            .securityReferences(defaultAuth())
            .forPaths(PathSelectors.regex(DEFAULT_INCLUDE_PATTERN))
            .build();
    }

    List<SecurityReference> defaultAuth() {
        AuthorizationScope authorizationScope
            = new AuthorizationScope("global", "accessEverything");
        AuthorizationScope[] authorizationScopes = new AuthorizationScope[1];
        authorizationScopes[0] = authorizationScope;
        return Lists.newArrayList(
            new SecurityReference("JWT", authorizationScopes));
    }
}

Access the ui via http://host:port/<context-root>/swagger-ui.html

Press Authorize all requests and enter Bearer [JWT_TOKEN]

Voila your next requests will have the JWT header

Answer 2

For a quick solution, I configured my docket with a global parameter authorization header in my swaggerConfig class.

    @Configuration
    @EnableSwagger2
    public class SwaggerConfig {
      private static final Set<String> DEFAULT_PRODUCES_CONSUMES = new HashSet<String>(Arrays.asList("application/json"));
    
      @Bean
      public Docket api() {
        ParameterBuilder parameterBuilder = new ParameterBuilder();
        parameterBuilder.name("Authorization")
                .modelRef(new ModelRef("string"))
                .parameterType("header")
                .description("JWT token")
                .required(true)
                .build();
        List<Parameter> parameters = new ArrayList<>();
        parameters.add(parameterBuilder.build());
        return new Docket(DocumentationType.SWAGGER_2).apiInfo(DEFAULT_API_INFO)
            .produces(DEFAULT_PRODUCES_CONSUMES)
            .consumes(DEFAULT_PRODUCES_CONSUMES)
            .select()
            .build()
            // Setting globalOperationParameters ensures that authentication header is applied to all APIs
            .globalOperationParameters(parameters);
      }
    }

Wrote a small post authorization-field-in-swagger-ui about this.

Answer 3

Your code is correct.

There is a bug in springfox-swagger-ui/springfox-swagger2 version 2.8.0 and it seems 2.9.2 as well. I suspect you are using a version effected by this bug.

I simply downgraded to 2.7.0 and it worked perfectly.

Answer 4

For swagger version 2.9.2

1. Create a SwaggerConfig class.

   @Bean
   public Docket api() {
       return new Docket(DocumentationType.SWAGGER_2)
               .select()
               .apis(RequestHandlerSelectors.any())
               .paths(PathSelectors.any())
               .build()
               .apiInfo(apiInfo())
               .securitySchemes(Arrays.asList(apiKey()));
   }
   
   private ApiInfo apiInfo() {
       return new ApiInfoBuilder()
               .title("Sig-Predict REST API Document")
               .description("work in progress")
               .termsOfServiceUrl("localhost")
               .version("1.0")
               .build();
   }
   
   private ApiKey apiKey() {
       return new ApiKey("jwtToken", "Authorization", "header");
   }
   

   2. Then annotate each API you would like to send this Authorization header to with:

      @ApiOperation(value = "", authorizations = { @Authorization(value="jwtToken") })
