Question

我有一个持久性捆绑包，大部分时间它完全正常，但每隔一段时间它就会卡在GracePeriod中，当发生这种情况时，缺少的依赖性是EntityManager：< / p>

karaf@root>bundle:diag 237
framework-connect-persistence (237)
 -----------------------------------
Status: GracePeriod
Blueprint
2/27/17 2:48 PM
Missing dependencies:
(&(osgi.unit.name=PersistenceUnitPrimary)(objectClass=javax.persistence.EntityManager))

但是，正如您所看到的，有一个EntityManager

karaf@root>service:list EntityManager
[javax.persistence.EntityManager]
 ---------------------------------
osgi.unit.name = PersistenceUnitPrimary
service.bundleid = 237
service.id = 427
service.scope = singleton
Provided by :
framework-connect-persistence (237)

重新启动捆绑包不会改变任何内容。但是，重新启动软件包org.apache.aries.jpa.blueprint可以解决问题

有什么想法吗？

谢谢

的persistence.xml：

Bundle随机进入GracePeriod
