概述

springfox之前配置需要声明多个依赖，到了3直接声明一个starter就行了.

springboot版本2.7.7
springfox-boot-starter版本3.0.0

配置

声明依赖

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

声明yml配置

spring:
  mvc:
    pathmatch:
      matching-strategy: ant_path_matcher

# 自定义的Swagger配置
swagger:
  # 是否开启swagger
  enabled: true
  enableSecurity: true
  info:
    # 标题
    title: '标题'
    # 描述
    description: '描述：用于XXX'
    # 版本
    version: '版本号: 1.0'
