pom.xml中引入的Swagger2依赖如下

<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>

Swagger2配置类

@Configuration
@EnableSwagger2
public class Swagger2 {
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("这里设置要扫描的包名"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("springboot利用swagger构建api文档")
                .description("简单优雅的restfun风格")
                .termsOfServiceUrl("")
                .version("1.0")
                .build();
    }
}

处理拦截

// 针对Swagger拦截放行
filterChainDefinitionMap.put("/swagger-ui.html", "anon");
filterChainDefinitionMap.put("/swagger/**", "anon");
filterChainDefinitionMap.put("/swagger-resources/**", "anon");
filterChainDefinitionMap.put("/v2/**", "anon");
filterChainDefinitionMap.put("/webjars/**", "anon");
filterChainDefinitionMap.put("/configuration/**", "anon");
