dependency>

2.yaml配置

spring:
  application:
    name: springfox-swagger
  mvc:
    pathmatch:
      matching-strategy: ant_path_matcher

swagger:
  enable: true
  application-name: ${spring.application.name}
  application-version: 1.0
  application-description: springfox swagger 3.0整合Demo
  try-host: http://localhost:${server.port}

3.启动
