Through the error message, it is judged that it is caused by a spring bean, but my project does not reference spring at all. It is suspected that it is caused by jar package conflict

Solution:
If Druid’s jar package is referenced in your project, it’s probably the problem. Upgrade the Druid jar package or downgrade the version of the Druid jar package in the project. We are from druid-1.0.10 upgrade to druid-1.0.3 problem solving. Druid’s jar package download address is attached.
