Consider defining a bean of type 'javax.persistence.EntityManagerFactory' in your configuration

提示：Parameter 1 of method springProcessEngineConfiguration in org.activiti.spring.boot.JpaProcessEngineAutoConfiguration$JpaConfiguration required a bean of type 'javax.persistence.EntityManagerFactory' that could not be found. springboot2.5集成activiti的时候出现错误

添加依赖
