NullPointerException：无法为org.jbpm.persistence.jpa持久性单元创建容器实体管理器工厂 [英] NullPointerException: Unable to create the container entity manager factory for the org.jbpm.persistence.jpa persistence unit

问题描述

我附加了persistence.xml和ormTasks.xml的前几行

I'm attaching the top few lines of my persistence.xml and ormTasks.xml

Persistence.xml

推荐答案

我可以通过将 hibernate.temp.use_jdbc_metadata_defaults 设置为false来解决此错误。我不知道你发表在哪里你会设置它的摘录。对我来说，这是持久化单元的Spring配置。

I was able to fix this error by setting hibernate.temp.use_jdbc_metadata_defaults to false. I'm not sure from the excerpts you posted where you would set it. For me it was the Spring config of the persistence unit.

这篇关于NullPointerException：无法为org.jbpm.persistence.jpa持久性单元创建容器实体管理器工厂的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
