Process finished with exit code 1
This can also happen if you are @ComponentScanning a springframework package (e.g. if you put a @ComponentScan in the default package by mistake)
可以参考如下步骤处理:
1.保证启动类在指定的包下面,不要直接放在java文件夹下面,要在java下面添加文件夹的.参考目录结构:
2.启动类上添加@ComponentScan注解，指定要扫描的包
如有帮助,欢迎采纳!
是java类找不到，r2dbc的介绍及使用，可参考 https://blog.csdn.net/wangqiso/article/details/110821147
是不是你的主类所在包名是org或者org.springframework打头的?
刚搭建springboot环境 这个问题是啥意思？
