Springboot2.6.0不兼容swagger3.0.0问题

版本

<parent>
  <groupId></groupId>
  <artifactId>spring-boot-starter-parent</artifactId>
  <version>2.6.0</version>
</parent>

版本 

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

原因分析：

spring5支持PathMatchConfigurer导致

启动报错解决方案1：

重写

两个类；

将PatternsRequestCondition改为PathPatternsRequestCondition；
