Org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaMappingContext': Invocation of init method failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name' entityManagerFactory' defined

The built environment has been tossing about for a long time, and later encountered this kind of similar problem. It turns out that this is the reason, and I have already cried and fainted.

Error reporting phenomenon:
