参考技术A 错误信息如下：

解决方案：

吼吼，犯了一个低级错误呢，有可能是你的项目刚执行了maven clean ,忘记 install 了。
重新install一次即可。

报错日志如上。

看日志是@SpringBootApplication注解里的一个属性proxyBeanMethods在@Configuration未找到。我到代码里查了一下，发现确实在目前依赖的Configuration.CLASS方法里未找到该方法。

因此猜测是现在使用的对应jar包有问题。

这次排查问题，我突然想到是否可以去github上查一下是否有人也遇到过。因为springboot在github上是开源的。地址https://github.com/spring-projects/spring-boot

结果我真的在该仓库的issue里查到了历史消息。

 

 看历史消息，其中有个印度小哥似乎意识到是jar包问题，但是升级jar包没有效果。结果被提醒该类在spring-context里。主要是看这个jar。

然后我就专门看了下自己的现在依赖的该包。把它升级到了5.2.3就解决了这个报错。
