Action:

Consider defining a bean named 'entityManagerFactory' in your configuration.

Because it’s a previous project, now I report an error. It’s said on the Internet to delete the package under hibernate in Maven warehouse, but it’s no use trying it; Later, I wondered if it was the version of springboot

So in the POM. XML file

The version of springboot starts from

<version>2.1.1.RELEASE</version>

Change to

<version>2.1.4.RELEASE</version>

Project ready to run

Another mistake
