Spring Boot Swagger 2構成エラー 'documentationPluginsBootstrapper'という名前のBeanの作成

Spring BootプロジェクトでSwaggerの構成に問題があります。私はこれの基本的な指示に従っていましたが、どういうわけかそれはうまくいきません。

ここにあります：pom.xml

 <!--SWAGGER-->
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger-ui</artifactId>
        <version>2.4.0</version>
    </dependency>

    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
        <version>2.4.0</version>
    </dependency>

Java Swagger設定：

@Configuration
@EnableSwagger2
public class SwaggerConfig {
@Bean
public Docket api() {
    return new Docket(DocumentationType.SWAGGER_2)
            .select()
            .apis(RequestHandlerSelectors.any())
            .paths(PathSelectors.any())
            .build();
    }
}

そして、私はこの例外を得ています：

SpringMVCでSwagger2を使用する場合は、次のように、構成クラスに「@EnableWebMvc」を追加する必要があります。

@Configuration
@EnableSwagger2
@EnableWebMvc
public class Swagger2Config {
   ……
}

ステップ1：SwaggerConfigクラスの@Configurationを削除する

ステップ2：そのようなコードを/WEB-INF/jetty-dispatcher-servlet.xmlに配置します

<mvc:resources mapping="swagger-ui.html" location="classpath:/META-INF/resources/"/>
<mvc:resources mapping="/webjars/**" location="classpath:/META-INF/resources/webjars/"/>

<!-- Include a swagger configuration-->
<bean name="swaggerConfig" class="com.exchangewalk.web.config.SwaggerConfig"/>

コンテキストには、デフォルトのSpringコンテキストとSpring MVCコンテキストの2つがあります。 @configurationアノテーションを使用している場合は、RequestMappingHandlerMappingが表示されないデフォルトのSpringコンテキストスキャンによってピックアップされます。そのため、SwaggerConfigがMVCコンテキストで定義されたBeanであることが重要です。
