配置 Swagger2

1. 引入相关依赖

<!--swagger-->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <scope>provided </scope>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <scope>provided </scope>
</dependency>

2. 创建 Swagger2 配置类

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket webApiConfig(){

        return new Docket(DocumentationType.SWAGGER_2)
                .groupName("webApi")
                .apiInfo(webApiInfo())
                .select()
                .paths(Predicates.not(PathSelectors.regex("/admin/.*")))
                .paths(Predicates.not(PathSelectors.regex("/error.*")))
                .build();

    }
    
    private ApiInfo webApiInfo(){

        return new ApiInfoBuilder()
                .title("网站-课程中心API文档")
                .description("本文档描述了课程中心微服务接口定义")
                .version("1.0")
                .contact(new Contact("Helen", "http://atguigu.com", "55317332@qq.com"))
                .build();
    }
}
