如何将swagger与jersey + spring-boot融为一体

标签: java spring-boot jersey swagger swagger-ui

我使用springboot + jersey进行web restful实现。现在我要将swagger整合到我们的应用程序中。我做了以下。

@Configuration
@EnableSwagger2
public class JerseyConfiguration extends ResourceConfig {

    public JerseyConfiguration(){
        register(HelloworldAPI.class);
        configureSwagger();
    }

    private void configureSwagger() {
        BeanConfig beanConfig = new BeanConfig();
        beanConfig.setVersion("1.0.2");
        beanConfig.setSchemes(new String[]{"http"});
        beanConfig.setHost("localhost:8080");
        beanConfig.setBasePath("/");
        beanConfig.setResourcePackage("com.cooltoo.api");
        beanConfig.setPrettyPrint(true);
        beanConfig.setScan(true);
    }
}

我在build.gradle上添加了以下依赖:

compile('io.springfox:springfox-swagger2:'+springfoxSwaggerVersion)
compile('io.springfox:springfox-petstore:'+springfoxSwaggerVersion)
compile('io.springfox:springfox-swagger-ui:'+springfoxSwaggerVersion)
compile('io.swagger:swagger-jersey2-jaxrs:1.5.8')

我能够启动网络应用程序,但我徘徊哪个网址是昂首阔步?我尝试使用http://localhost:8080http://localhost:8080/swaggerhttp://localhost:8080/swagger-ui.html。但是没有一个可以被访问。

如果使用Spring MVC而不是JAX-RS实现来实现端点,我认为@EnableSwagger2注释和springfox依赖项将起作用。

几个月前我在博客上发表了这篇文章,Microservices using Spring Boot, Jersey Swagger and Docker

基本上,如果您需要记录Jersey实施的端点,则需要:

1) 确保您的Spring Boot应用程序通过以下方式扫描位于特定软件包中的组件(即com.asimio.jerseyexample.config):

@SpringBootApplication(
    scanBasePackages = {
        "com.asimio.jerseyexample.config", "com.asimio.jerseyexample.rest"
    }
)

2)Jersey配置类实现:

package com.asimio.jerseyexample.config;
...
@Component
public class JerseyConfig extends ResourceConfig {

    @Value("${spring.jersey.application-path:/}")
    private String apiPath;

    public JerseyConfig() {
        // Register endpoints, providers, ...
        this.registerEndpoints();
    }

    @PostConstruct
    public void init() {
        // Register components where DI is needed
        this.configureSwagger();
    }

    private void registerEndpoints() {
        this.register(HelloResource.class);
        // Access through /<Jersey's servlet path>/application.wadl
        this.register(WadlResource.class);
    }

    private void configureSwagger() {
        // Available at localhost:port/swagger.json
        this.register(ApiListingResource.class);
        this.register(SwaggerSerializers.class);

        BeanConfig config = new BeanConfig();
        config.setConfigId("springboot-jersey-swagger-docker-example");
        config.setTitle("Spring Boot + Jersey + Swagger + Docker Example");
        config.setVersion("v1");
        config.setContact("Orlando L Otero");
        config.setSchemes(new String[] { "http", "https" });
        config.setBasePath(this.apiPath);
        config.setResourcePackage("com.asimio.jerseyexample.rest.v1");
        config.setPrettyPrint(true);
        config.setScan(true);
    }
}

3)使用JAX-RS(Jersey)和Swagger注释的资源实现:

package com.asimio.jerseyexample.rest.v1;
...
@Component
@Path("/")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
@Api(value = "Hello resource", produces = "application/json")
public class HelloResource {

    private static final Logger LOGGER = LoggerFactory.getLogger(HelloResource.class);

    @GET
    @Path("v1/hello/{name}")
    @ApiOperation(value = "Gets a hello resource. Version 1 - (version in URL)", response = Hello.class)
    @ApiResponses(value = {
        @ApiResponse(code = 200, message = "Hello resource found"),
        @ApiResponse(code = 404, message = "Hello resource not found")
    })
    public Response getHelloVersionInUrl(@ApiParam @PathParam("name") String name) {
        LOGGER.info("getHelloVersionInUrl() v1");
        return this.getHello(name, "Version 1 - passed in URL");
    }
...
}

4)确保您的应用程序的Spring Boot配置文件区分Spring MVC(用于执行器端点)和Jersey(用于资源)端点:

<强> application.yml

...
# Spring MVC dispatcher servlet path. Needs to be different than Jersey's to enable/disable Actuator endpoints access (/info, /health, ...)
server.servlet-path: /
# Jersey dispatcher servlet
spring.jersey.application-path: /api
...

我建议使用依赖关系并启动。在Spring Boot中使用Swagger相当容易,但是要与Jersey一起使用时可能会很棘手。

我们要做的第一件事是配置Swagger以与Jersey一起使用并按如下所示更新您的Jersey配置。

Jersey Config是我们需要进行所有配置的地方

import io.swagger.jaxrs.config.BeanConfig;
import io.swagger.jaxrs.listing.ApiListingResource;
import io.swagger.jaxrs.listing.SwaggerSerializers;

import javax.annotation.PostConstruct;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;

import org.glassfish.jersey.server.ResourceConfig;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
    @Component
    @ApplicationPath("/api")
    public class JerseyConfig extends ResourceConfig {
        @Autowired
        public JerseyConfig(ObjectMapper objectMapper) {

            packages("com.rest.resources"); 
            // u can also specify resource class names like below
            //register(UserResource.class)  
            //register(AdminResource.class)

        }

         @PostConstruct
          public void init() {
            // Register components where DI is needed
            this.SwaggerConfig();
          }
        private void SwaggerConfig() {
            this.register(ApiListingResource.class);
            this.register(SwaggerSerializers.class);

            BeanConfig swaggerConfigBean = new BeanConfig();
            swaggerConfigBean.setConfigId("Swagger Jersey Example");
            swaggerConfigBean.setTitle("Using Swagger ,Jersey And Spring Boot ");
            swaggerConfigBean.setVersion("v1");
            swaggerConfigBean.setContact("DeveloperName");
            swaggerConfigBean.setSchemes(new String[] { "http", "https" });
            swaggerConfigBean.setBasePath("/api");
            swaggerConfigBean.setResourcePackage("com.rest.resources");
            swaggerConfigBean.setPrettyPrint(true);
            swaggerConfigBean.setScan(true);
          }

现在我们已经完成了所有配置,我们需要验证swagger.json是否成功生成。这是重要的步骤,请验证以下URL。

http://localhost:PORT/baseContext/api/swagger.json

由于我们将@Application路径指定为“ / api”,并且尚未配置任何上下文,因此我们的基本上下文为“ /”。因此,我们以 http://localhost:8080/api/swagger.json

现在,我们的swagger.json已加载,我们现在需要配置Swagger UI。 就像静态HTML或简单Web应用程序中的资源访问一样。

如果不确定如何配置,请 visit this article,在文章结尾处说明如何加载swagger-UI

也许您使用相当旧版本的springfox,但现在(版本2.4.0)必须配置与您的代码完全不同,请参阅http://springfox.github.io/springfox/docs/current/

例如,我有以下springfox配置:

@Configuration
@EnableSwagger2
class SwaggerConfig {
    @Bean
    Docket rsApi() {
        new Docket(DocumentationType.SWAGGER_12)
            .apiInfo(apiInfo())
            .select()
                    .apis(RequestHandlerSelectors.basePackage('com.test.service'))
            .paths(PathSelectors.any())
            .build()
            .pathMapping('/')
            .useDefaultResponseMessages(false)
    }

    private ApiInfo apiInfo() {
        new ApiInfoBuilder()
            .title('Test API')
            .description('Test API')
            .version('0.0.10.SNAPSHOT')
            .termsOfServiceUrl('')
            .contact('Test company')
            .license('Public')
            .licenseUrl('http://example.com/')
            .build()
    }
}
