我想将 spring boot v2.1.9 升级到 2.2.0。但是升级后我得到了一些例外，它说 spring fox 使用的是旧版本的 spring-plugin-core。
有没有其他替代解决方案，或者我需要放弃 springfox 插件吗？

我尝试使用 Many POC 来同步 Kafka 和 DB 之间的事务，但在某些情况下我失败了，并且我搜索了许多存储库、博客以获取至少一个示例。我现在还没有得到任何例子。
如果有人提供至少一个示例或配置，这将是未来所有人的一个很好的参考。
我有使用 spring boot V2.1.9.RELEASE 版本的 spring boot 应用程序。我只想升级spring Kafka。但是升级后我没有发现这样的方法错误。
我尝试将 Spring Boot 升级到 2.2.0，但由于其他一些插件（如 swagger）不支持。
