Camel Jpa Hibernate屬性訪問異常在Karaf容器中重新啓動包後

JPA相當新穎，我有一條駱駝路線使用它，所以我在準確理解我的問題以及如何解決問題時遇到了一些麻煩。經過一堆更多的測試後，我發現這個錯誤似乎只發生在我的karaf容器中重新啓動我的包之後。如果我第一次加載容器並安裝它，一切似乎都運行良好。我將自己的特徵文件信息Camel Jpa Hibernate屬性訪問異常在Karaf容器中重新啓動包後

確定您的POJO類中有一個名爲'getPackageTrackingNumber（）'的公共方法？ – Vihar

是的，我爲每個變量都包含getter和setter，包括PackageTrackingNumber：public String getPackageTrackingNumber（）{return packageTrackingNumber;} –

也許這個鏈接會幫助你http://stackoverflow.com/questions/27771440/javax-persistence-persistenceexception- org-hibernate-propertyaccessexception-c在hibernate.properties文件或persistence.xml文件中添加hibernate.classloading.use_current_tccl_as_parent = false。 –

經過大量的樂趣後，OSGI和Hibernate看起來並不是很好。我發現一些JIRA門票的增強功能可以改善這一點。現在，我正在對應用程序卸載和重新安裝之間的hibernate相關軟件包發佈刷新命令。

https://hibernate.atlassian.net/browse/HHH-9818

https://hibernate.atlassian.net/browse/HHH-8501

指出：休眠-OSGI 6是使其正常工作需要。

Hibernate 5現在有一個非常好的OSGi集成，請參閱http://docs.jboss.org/hibernate/orm/5.1/userguide/html_single/Hibernate_User_Guide.html#osgi –

真棒夢幻般的鏈接。很高興知道，一旦我更新到4.3版本，它看起來像被照顧了。我將不得不檢查Redhat補丁程序週期以查看FUSE平臺是否會捆綁該修復程序。謝謝你的信息！ –

其實現在hibernate直接提供了karaf和jboss的保險絲功能文件https://repo1.maven.org/maven2/org/hibernate/hibernate-osgi/5.1.0.Final/hibernate-osgi-5.1.0.Final -karaf.xml –
