本篇文章要实现的功能：

• 1.集成swagger
• 2.集成swagger登录功能，访问 /swagger-ui.html需要先登录
• 3.集成安全认证，访问接口时携带header

请求接口时携带了上一步输入的header参数和值

1.集成swagger

jdk11，SpringBoot 2.7.13
pom.xml依赖swagger2.10.5

<dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger2</artifactId><version>2.10.5</version>
</dependency>
<dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger-ui</artifactId><version>2.10.5</version>
</dependency>
<dependency><groupId>io.springfox</groupId><artifactId>springfox-spring-webmvc</artifactId><version>2.10.5</version>
</dependency>

application.yml

swagger:enable: true   #是否开启swaggerbasic:enable: true  #是否开启登录认证username: adminpassword: admin

2.集成swagger登录功能，访问 /swagger-ui.html需要先登录
