第一步：Maven引入Swagger3.0 starter依赖Maven项目中引入springfox-boot-starter依赖：
io.springfoxspringfox-boot-starter3.0.0备注：依赖更加简单 ， 不再需要springfox-swagger2 和 springfox-swagger-ui 这两个依赖 。
第二步：增加application.yml配置swagger:enable: trueapplication-name: ${spring.application.name}application-version: 1.0application-description: springfox swagger 3.0整合Demotry-host: http://localhost:${server.port}spring:application:name: springfox-swagger第三步：启用swagger配置【「尝鲜」SpringBoot 快速整合 Swagger3.0】使用@EnableOpenApi注解 ， 启用swagger配置
@EnableOpenApi@Configurationpublic class SwaggerConfiguratio {}第四步：启动测试访问地址：
