Konfigurieren der Swagger-Benutzeroberfläche mit Spring Boot
Ich versuche, die Swagger-Benutzeroberfläche mit meiner Spring-Boot-Anwendung zu konfigurieren. Obwohl der v2/api-docs anscheinend ordnungsgemäß geladen wird, lädt der http://localhost:8080/swagger-ui.html meine kommentierte REST - API nicht.
Folgendes habe ich:
pom.xml:
...
<!--Swagger UI-->

<artifactId>springfox-swagger2</artifactId>
<version>2.6.1</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>

Die swagger-ui.html (http://localhost:8080/swagger-ui.html) zeigt nicht die erwarteten REST - Aufrufe: 
Der Fehler in swagger-ui.html von der Codeüberprüfung: Failed to load resource: the server responded with a status of 404 ().
Ich habe gegoogelt (auch Web-Config-mvc ausprobiert), aber der Fehler bleibt bestehen. Möglicherweise fehlt mir eine Ressourcenreferenz in der .iml-Datei.
Ich hatte dieses Problem heute und habe es behoben, indem ich die Versionen meiner springfox-swagger2- und springfox-swagger-ui-Abhängigkeiten abgeglichen habe:
<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>
Es gibt sehr wenig anderen Code, um es einfach zum Laufen zu bringen. Eine einfache Konfigurationsklasse:
@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();
}
}
Und meine application.properties
# location of the swagger json
springfox.documentation.swagger.v2.path=/swagger.json
(Dies ist in Spring Boot).
Anweisung: Generieren Sie die Swagger-Benutzeroberfläche für die Auflistung aller REST - APIs über die Spring Boot-Anwendung.
Führen Sie die folgenden Schritte aus, um den Swagger UI über die Spring Boot-Anwendung zu generieren:
1. Füge folgende Abhängigkeit in pom.xml hinzu -
<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. Fügen Sie in Ihrer Hauptanwendungsklasse den folgenden Code mit der @ EnableSwagger2-Annotation hinzu.
@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. Fügen Sie die unten stehende RootController-Klasse in Ihren Code ein, um zur Swagger-Benutzeroberflächenseite umzuleiten. Auf diese Weise müssen Sie den dist-Ordner der Swagger-UI nicht in Ihrem Ressourcenverzeichnis ablegen.
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. Als letzten Schritt fügen Sie die @Api- und @ApiOperation-Notation in alle Ihre RESTController wie folgt hinzu:
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";
}
}
Jetzt bist du fertig. Um Ihre Spring Boot Application auszuführen, gehen Sie zum Browser und geben Sie localhost:8080 ein. Sie sehen Swagger UI mit allen Details Ihrer REST - APIs.
Glückliche Kodierung. ????
Der Quellcode der obigen Implementierung befindet sich auch in meinem blog wenn Sie Lust haben, es auszuprobieren.
Am besten konfigurieren Sie Swagger in Ihrer Anwendung, indem Sie zuerst hinzufügen
<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>
in pom.xml
und fügen Sie dann das Plugin unter dem Plugin hinzu
<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>

<phase>compile</phase>

Diese Konfiguration erstellt automatisch eine Swagger-Json-Datei und konfiguriert die Swagger-Benutzeroberfläche in Ihrer Anwendung.
Fügen Sie eine Konfigurationsklasse wie diese hinzu
@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/");
}
}
