需要哪些细节我后续上传，我感觉报错原因主要是在这里，所以就传了这个报错信息

@khzl 一般 create bean error 只是结果，还会有更深的原因。建议把整个异常堆栈全部 po 上来。

还是看不出来原因。如果你闲的话可以把代码推到 github 放个链接，我 pull 下来试试~

Caused by: java.lang.NoClassDefFoundError: reactor/retry/Repeat 看看是否 jar 宝版本冲突了

解决了，是 jar 包中文件有缺失，我用镜像下载过来的 jar 包少了一些文件。后面在别人那里考了一个过来，在运行就好了。之前也考过来试了，可能细节没做好还是报错了，所以给忽略了
