Spring Boot Swagger 2 Configuration Error creating bean with name 'documentationPluginsBootstrapper'

Question

I have problems with configuration of Swagger in my Spring Boot project. I was following the basic instruction for this, and somehow it doesn's work.

Here it is: 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 Config:

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

And i am getting this Exception:

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'documentationPluginsBootstrapper' defined in URL [jar:file:/C:/Users/Admin/.m2/repository/io/springfox/springfox-spring-web/2.4.0/springfox-spring-web-2.4.0.jar!/springfox/documentation/spring/web/plugins/DocumentationPluginsBootstrapper.class]: BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.transaction.annotation.ProxyTransactionManagementConfiguration': Initialization of bean failed; nested exception is java.lang.NoSuchMethodError: org.springframework.transaction.annotation.ProxyTransactionManagementConfiguration.setBeanFactory(Lorg/springframework/beans/factory/BeanFactory;)V

With Spring boot, you don't need the `@Configuration`. See more http://stackoverflow.com/questions/32449612/spring-boot-springbox-swagger-error — Alee, Mar 08 '17 at 16:30
just a hint : check endpoints if there was a duplicate value, this error will occur. — fuat, Apr 03 '20 at 17:26

In SpringMVC, if you want to use Swagger2,you need add '@EnableWebMvc' in you config class,like this:

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

Fixed it with removing @Configuration annotation in SwaggerConfuguration class.

Only keep @EnableSwagger2 annotation

@EnableSwagger2
public class SwaggerConfiguration {

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

P.S. My dependencies:

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

that only switched from swagger3 to oas3, but did not resolve the issue. — Sasha Bond, Apr 12 '22 at 19:41

step 1: Remove the @Configuration in SwaggerConfig Class

step 2: put such code in /WEB-INF/jetty-dispatcher-servlet.xml

<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"/>

There are two contexts, the default spring context and the spring MVC context. If you're using the @configuration annotation, that gets picked up by the default spring context scanning which has no visibility of the RequestMappingHandlerMapping. That's why it's important that the SwaggerConfig is a bean defined in the MVC context.

For details, please refer: https://github.com/springfox/springfox/issues/462

I had this problem when in pom.xml were spring-boot both dependencies for webflux and web were added:

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-webflux</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

spring-boot-starter-webflux generated problem in that case. I used springfox:

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-boot-starter</artifactId>
            <version>3.0.0</version>
        </dependency>

For me it was enough to eliminate webflux dependency, which was added accidentally, but maybe for someone this info will be useful.

Removing @Configuration fixed my issue but swagger stopped working for obvious reason
