原因

swagger的版本和springboot版本不兼容

我的项目swagger使用的版本是3.0.0

implementation 'io.springfox:springfox-boot-starter:3.0.0'
implementation 'com.github.xiaoymin:knife4j-spring-boot-starter:3.0.3'

springboot版本是3.1.4

id('org.springframework.boot').version('3.1.4')
解决办法

降低一点springboot版本

id('org.springframework.boot').version('2.7.3')
