我在Spring Boot项目中配置Swagger时出现问题。 我正在遵循这方面的基本指示，不知何故它没有工作。

这是： 的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配置：

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

我得到了这个例外：

在SpringMVC中，如果你想使用Swagger2，你需要添加＆＃39; @ EnableWebMvc＆＃39;在你的配置类中，像这样：

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

步骤1：删除SwaggerConfig类中的@Configuration

第2步：将此类代码放入/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"/>

有两个上下文，默认的spring上下文和spring MVC上下文。如果您正在使用@configuration注释，那么默认的Spring上下文扫描将会捕获该注释，该扫描没有RequestMappingHandlerMapping的可见性。这就是为什么SwaggerConfig是MVC上下文中定义的bean非常重要。

我在 pom.xml 中的 spring-boot 中遇到了这个问题，同时添加了 webflux 和 web 的依赖项：

        <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 在这种情况下会产生问题。 我用过springfox：

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

对我来说，这足以消除意外添加的 webflux 依赖项，但也许对于某些人来说，此信息会很有用。

通过删除 SwaggerConfuguration 类中的 @Configuration 注释来修复它。

只保留@EnableSwagger2 注释

@EnableSwagger2
public class SwaggerConfiguration {

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

附言我的依赖：

        <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>
