After springboot is connected to the springcloud-alibaba framework, an error will be reported at startup. It is difficult to troubleshoot according to the error message, so it can only be troubleshoot step by step. The reason for the problem I am currently encountering is that springboot, SpringCloud, and SpringCloudAlbaba directly have version dependencies. These three components must choose to specify the corresponding version number , otherwise an error will be reported when starting.
