Configuration de l'interface utilisateur Swagger avec Spring Boot
J'essaie de configurer l'interface utilisateur Swagger avec mon application de démarrage Spring. Bien que le v2/api-docs semble se charger correctement, le http://localhost:8080/swagger-ui.html ne charge pas mon API annotée REST.
Voici ce que j'ai

Le swagger-ui.html (http://localhost:8080/swagger-ui.html) n'affiche pas les appels REST attendus: 
L'erreur dans swagger-ui.html à partir de l'inspection de code: Failed to load resource: the server responded with a status of 404 ().
J'ai googlé (essayé de web-config mvc aussi) mais l'erreur persiste. Peut-être me manque une référence de ressource dans le fichier .iml?
J'ai eu ce problème aujourd'hui et je l'ai corrigé en faisant correspondre les versions de mes dépendances springfox-swagger2 et springfox-swagger-ui:
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.6.1</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.6.1</version>
</dependency>
Il y a très peu de code pour le mettre en marche. Une classe de configuration simple:
@Configuration
@EnableSwagger2
class SwaggerConfiguration {
@Bean
public Docket api() {
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(RequestHandlerSelectors.basePackage("com.foo.samples.swaggersample"))
.paths(PathSelectors.any())
.build();
}
}
Et mes application.properties
# location of the swagger json
springfox.documentation.swagger.v2.path=/swagger.json
(Ceci est dans Spring Boot).
Instruction: Générez l'interface utilisateur Swagger pour la liste de toutes les API REST via l'application de démarrage Spring.
Suivez les étapes ci-dessous pour générer l'application Swagger UI à Spring Boot:
1. Ajouter la dépendance suivante dans pom.xml -
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.6.1</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.6.1</version>
</dependency>
2. Ajoutez l'élément de code suivant dans votre classe d'application principale avec l'annotation @ EnableSwagger2.
@EnableSwagger2
@SpringBootApplication
public class MyApp {
public static void main(String[] args) {
SpringApplication.run(MyApp.class, args);
}
@Bean
public Docket api() {
return new Docket(DocumentationType.SWAGGER_2).select()
.apis(RequestHandlerSelectors.withClassAnnotation(Api.class))
.paths(PathSelectors.any()).build().pathMapping("/")
.apiInfo(apiInfo()).useDefaultResponseMessages(false);
}
@Bean
public ApiInfo apiInfo() {
final ApiInfoBuilder builder = new ApiInfoBuilder();
builder.title("My Application API through Swagger UI").version("1.0").license("(C) Copyright Test")
.description("List of all the APIs of My Application App through Swagger UI");
return builder.build();
}
}
3. Ajoutez la classe RootController ci-dessous dans votre code pour la redirection vers la page de l'interface utilisateur Swagger. De cette manière, vous n’avez pas besoin de mettre le dossier dist de Swagger-UI dans votre répertoire de ressources.
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
@RequestMapping("/")
public class RootController {
@RequestMapping(method = RequestMethod.GET)
public String swaggerUi() {
return "redirect:/swagger-ui.html";
}
}
4. Comme étapes finales, ajoutez les notations @Api et @ApiOperation dans tous vos contrôleurs REST comme ci-dessous -
import static org.springframework.web.bind.annotation.RequestMethod.GET;
import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseStatus;
import org.springframework.web.bind.annotation.RestController;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
@RestController
@RequestMapping("/hello")
@Api(value = "hello", description = "Sample hello world application")
public class TestController {
@ApiOperation(value = "Just to test the sample test api of My App Service")
@RequestMapping(method = RequestMethod.GET, value = "/test")
// @Produces(MediaType.APPLICATION_JSON)
public String test() {
return "Hello to check Swagger UI";
}
@ResponseStatus(HttpStatus.OK)
@RequestMapping(value = "/test1", method = GET)
@ApiOperation(value = "My App Service get test1 API", position = 1)
public String test1() {
System.out.println("Testing");
if (true) {
return "Tanuj";
}
return "Gupta";
}
}
Maintenant, vous avez terminé. Maintenant, pour exécuter votre application de démarrage Spring, accédez au navigateur et tapez localhost:8080. Swagger UI contient tous les détails de vos API REST.
Bonne codage. ????
Le code source de l’implémentation ci-dessus se trouve également sur mon blog si vous avez envie de le vérifier.
Le meilleur moyen de configurer swagger dans votre application est d’abord d’ajouter
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.6.1</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.6.1</version>
</dependency>
dans pom.xml
puis ajoutez le plugin ci-dessous plugin
<plugin>
<groupId>com.github.kongchen</groupId>
<artifactId>swagger-maven-plugin</artifactId>
<version>3.1.5</version>
<configuration>
<apiSources>
<apiSource>
<springmvc>true</springmvc>
<locations>com.sandy2friends.test.web.rest</locations>
<info>
<title>REST API</title>
<version>1</version>
<description>REST API</description>
</info>
<swaggerDirectory>swagger</swaggerDirectory>
<swaggerFileName>rest api</swaggerFileName>
</apiSource>
</apiSources>
</configuration>
<executions>
<execution>
<phase>compile</phase>
<goals>
<goal>generate</goal>
</goals>
</execution>
</executions>
</plugin>
cliquez ici pour en savoir plus sur le plugin
Cette configuration créera automatiquement le fichier swagger json et configurera swagger ui dans votre application.
Ajouter une classe de configuration comme celle-ci
@Configuration
public class WebMvcConfiguration extends WebMvcConfigurationSupport {
@Override
public void addResourceHandlers(final ResourceHandlerRegistry registry) {
// Make Swagger meta-data available via <baseURL>/v2/api-docs/
registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
// Make Swagger UI available via <baseURL>/swagger-ui.html
registry.addResourceHandler("/**").addResourceLocations("classpath:/META-INF/resources/");
}
}
