Question

1.Springboot项目启动,爆创建名为“configDataContextRefresher”[SpringBoot]的bean时发生java错误
网上说是nacos与springboot的版本不一致，但是这是个springboot项目，没有用到nacos?

Answer 1

以下回答参考GPT并且由Bony-整理：
根据您提供的错误日志，似乎是在创建SpringBoot项目时出现了问题，具体是在创建名为“configDataContextRefresher”的bean时发生了java错误。

有些网上资料表明这个问题可能是由于Nacos和SpringBoot的版本不一致引起的，但是根据您的描述，这是一个纯SpringBoot项目，没有使用Nacos。因此，需要考虑其他可能的原因。

根据日志中的信息，看起来是在创建名为“configDataContextRefresher”的bean时出现了问题。这个bean属于Spring Cloud中的RefreshAutoConfiguration类，可能是由于在Spring Cloud和Spring Boot版本之间存在不兼容性导致的。您可以检查一下您使用的Spring Cloud和Spring Boot版本是否兼容。

另外，日志中还显示了一个java.lang.ClassNotFoundException异常，指出找不到org.springframework.boot.logging.DeferredLogFactory类。这可能是由于缺少某些必要的依赖项引起的。您可以检查一下项目中的依赖项是否正确，并尝试重新构建项目。

综上所述，您可以尝试以下解决方案：

检查Spring Cloud和Spring Boot版本是否兼容。
检查项目的依赖项是否正确，并尝试重新构建项目。
如果仍然无法解决问题，请提供更多的信息，例如项目的pom.xml文件以及其他相关配置文件，以便更好地了解问题的来源。
