普元 AppServer 6.5 业务应用部署报错：

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'javax.persistence.EntityManagerFactory' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

问题原因

应用引用的activiti-spring-boot-starter-basic-6.0.0.jar的org.activiti.spring.boot.JpaProcessEngineAutoConfiguration类的@ConditionalOnClass(name= "javax.persistence.EntityManagerFactory")，根据javax.persistence.EntityManagerFactory类去创建bean，和javax.persistence中的冲突了

解决方案

项目里参考https://www.cnblogs.com/jiangwz/p/9758742.html中的方法，引入了activiti-spring-boot-starter-jpa的jar。
