使用Springfox为OASP4j生成Swagger.json（Spring启动）cxf Rest服务

时间：2018-06-12 14:58:17

标签： maven spring-boot cxf swagger springfox

我正在尝试为我们基于OASP4J的项目生成一个swagger.json。它使用spring boot和Apache cxf服务框架来开发Rest服务。 我已经尝试了不同的教程，但似乎没有任何工作。 主要问题是生成了文件，但api列表为空。每个休息服务都在此路径下localhost:8081/attivazioni/services/rest/general/v1/

SpringBootApp.java 

@SpringBootApplication(exclude = { EndpointAutoConfiguration.class })
@EntityScan(basePackages = { "\"it.lispa.sire.attivazioni" }, basePackageClasses = { AdvancedRevisionEntity.class })
@EnableSwagger2
@EnableGlobalMethodSecurity(jsr250Enabled = true)
public class SpringBootApp {

  /**
   * Entry point for spring-boot based app
   *
   * @param args - arguments
   */
  public static void main(String[] args) {

    SpringApplication.run(SpringBootApp.class, args);
  }
}

JerseyConfig.java 

@Component
@ApplicationScope("/attivazioni")
public class JerseyConfig extends ResourceConfig {

  public JerseyConfig() {

    BeanConfig swaggerConfig = new BeanConfig();
    swaggerConfig.setBasePath("/attivazioni");
    SwaggerConfigLocator.getInstance().putConfig(SwaggerContextService.CONFIG_ID_DEFAULT, swaggerConfig);

    packages(getClass().getPackage().getName(), ApiListingResource.class.getPackage().getName());
  }

}

CombinedSwaggerResourcesProvider.java 

@Component
@Primary
public class CombinedSwaggerResourcesProvider implements SwaggerResourcesProvider {

  @Resource
  private InMemorySwaggerResourcesProvider inMemorySwaggerResourcesProvider;

  @Override
  public List<SwaggerResource> get() {

    SwaggerResource jerseySwaggerResource = new SwaggerResource();
    jerseySwaggerResource.setLocation("/attivazioni/swagger.json");
    jerseySwaggerResource.setSwaggerVersion("2.0");
    jerseySwaggerResource.setName("Jersey");

    return Stream.concat(Stream.of(jerseySwaggerResource), this.inMemorySwaggerResourcesProvider.get().stream())
        .collect(Collectors.toList());
  }

}

ServiceConfig.java 

@Configuration
@EnableWs
@ImportResource({ "classpath:META-INF/cxf/cxf.xml" })
public class ServiceConfig extends WsConfigurerAdapter {

  /** Logger instance. */
  private static final Logger LOG = LoggerFactory.getLogger(ServiceConfig.class);

  /** The services "folder" of an URL. */
  public static final String URL_FOLDER_SERVICES = "services";

  public static final String URL_PATH_SERVICES = "/private/" + URL_FOLDER_SERVICES;

  public static final String URL_FOLDER_REST = "/rest";

  public static final String URL_FOLDER_WEB_SERVICES = "/ws";

  public static final String URL_PATH_REST_SERVICES = URL_PATH_SERVICES + "/" + URL_FOLDER_REST;

  public static final String URL_PATH_WEB_SERVICES = URL_PATH_SERVICES + "/" + URL_FOLDER_WEB_SERVICES;

  @Value("${security.expose.error.details}")
  boolean exposeInternalErrorDetails;

  @Inject
  private ApplicationContext applicationContext;

  @Inject
  private ObjectMapperFactory objectMapperFactory;

  @Bean(name = "cxf")
  public SpringBus springBus() {

    return new SpringBus();
  }

  @Bean
  public JacksonJsonProvider jacksonJsonProvider() {

    return new JacksonJsonProvider(this.objectMapperFactory.createInstance());
  }

  @Bean
  public ServletRegistrationBean servletRegistrationBean() {

    CXFServlet cxfServlet = new CXFServlet();
    ServletRegistrationBean servletRegistration = new ServletRegistrationBean(cxfServlet, URL_PATH_SERVICES + "/*");
    return servletRegistration;
  }

  @Bean
  public Server jaxRsServer() {

    // List<Object> restServiceBeans = new
    // ArrayList<>(this.applicationContext.getBeansOfType(RestService.class).values());
    Collection<Object> restServices = findRestServices();
    if (restServices.isEmpty()) {
      LOG.info("No REST Services have been found. Rest Endpoint will not be enabled in CXF.");
      return null;
    }
    Collection<Object> providers = this.applicationContext.getBeansWithAnnotation(Provider.class).values();

    JAXRSServerFactoryBean factory = new JAXRSServerFactoryBean();
    factory.setBus(springBus());
    factory.setAddress(URL_FOLDER_REST);
    factory.setServiceBeans(new ArrayList<>(restServices));
    factory.setProviders(new ArrayList<>(providers));
    return factory.create();
  }

  private Collection<Object> findRestServices() {

    return this.applicationContext.getBeansWithAnnotation(Path.class).values();
  }

  @Bean
  public RestServiceExceptionFacade restServiceExceptionFacade() {

    RestServiceExceptionFacade exceptionFacade = new RestServiceExceptionFacade();
    exceptionFacade.setExposeInternalErrorDetails(this.exposeInternalErrorDetails);
    return exceptionFacade;
  }

}

我认为你需要创建一个Docket bean，如下所示：

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    @Bean
    public Docket publicApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.foo.bar"))
                .paths(PathSelectors.ant("/api/**"))
                .build()
                .securitySchemes(Collections.singletonList(new BasicAuth("basic")))
                .apiInfo(apiInfo());
    }

    private ApiInfo apiInfo() {
        return new ApiInfo(
                "REST Service API",
                "V1 Service API endpoints",
                "1",
                "Terms of Service",
                new Contact("Digital Support", "www.foo.bar", "digitalsupport@foo.bar"),
                "Apache 2.0",
                "http://www.apache.org/licenses/LICENSE-2.0.html",
                Collections.<VendorExtension>emptyList()
        );
    }
}

我在一个独立的配置类中使用它，而不是将它放在主要的spring-boot应用程序类中。

除了这个配置之外，唯一的一点是对控制器方法的一些注释：@ApiOperation(value = "Get Paged Accounts. Requires ADMIN Role", produces = MediaType.APPLICATION_JSON_UTF8_VALUE)

请参阅cxf swagger example project，以便从具有Swagger Annotations的CXF Rest服务生成swagger.json。您需要添加cxf-rt-rs-service-description-swagger maven依赖项并将Swagger2Feature添加到JAXRSServerFactoryBean（在您的情况下，您必须设置为factory.setFeatures(new Swagger2Feature())）
