java - JPA/hibernate : @PersistenceContext unitName has multiple matches error

Question

我正在做一个项目，到目前为止进展顺利，直到我检查了另一个团队的最新更改，以处理最新的文件(不要专注于那个文件)。我正在使用 Tomcat OpenEJB 3.1、JPA 和 Hibernate 3.2.6。问题是什么，在部署应用程序后它卡住了:

我仔细检查了所有的基本设置，没有任何改变。有人遇到过这种问题吗？

我将感谢对此主题的任何支持。

谢谢

我猜你的 persistence.xml 在你的类路径中有 16 次。清理多余的。
