Spring Boot Swagger 2コンフィグレーションで 'documentationPluginsBootstrapper'という名前のBeanを作成中にエラーが発生しました

Question

Spring BootプロジェクトでSwaggerの設定に問題があります。 私はこれのための基本的な指示に従っていた、とにかくそれは何の仕事でもありません。

ここでは、次のとおりです。 の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> 

のJava闊歩設定：

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

、私はこの例外を取得しています：

Answer 1

はSwaggerConfigで@Configurationを削除しますクラスがあなたの問題を解決します。

デフォルトのスプリングコンテキストとスプリングMVCコンテキストの2つのコンテキストがあります。 @configurationアノテーションを使用している場合、RequestMappingHandlerMappingの可視性のないデフォルトのスプリングコンテキストスキャンによって取得されます。そのため、SwaggerConfigはMVCコンテキストで定義されたBeanであることが重要です。

詳細については、参照してください：あなたはSwagger2を使用したい場合はhttps://github.com/springfox/springfox/issues/462

Answer 2

はSpringMVCでは、追加必要な「@EnableWebMvc君コンフィグクラスで、次のように：

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