重新启动 Karaf 后，此问题消失并持续存在。

我不想每次都重启 karaf。

我发现在我的捆绑包更新后我需要执行以下步骤：

刷新 hibernate-osgi 包 重启我的包

然后一切都开始工作了，但我不想每次都刷新 hibernate-osgi 并重新启动我的包。

我正在使用 Apache Karaf 3.0.3、Hibernate 4.3.6、Java 1.8.0_60。

【参考方案1】：

请注意，这在 Hibernate ORM OSGi 4.x 和 5.0.x 中是绝对预期的。重新启动应用程序包对 hibernate-osgi 和最终的 hibernate-core 具有灾难性的后果。在https://hibernate.atlassian.net/browse/HHH-9818 得到纠正之前（我们将尽快处理），Hibernate ORM OSGi 应该被视为静态，而不是动态响应 OSGi 捆绑事件。

【参考方案2】：

您需要对 hibernate-bundle 进行刷新，因为它不知道更新后的捆绑包发生了变化，它仍然保留对旧捆绑包的引用。因此，更新始终也需要刷新其他捆绑包。 这是设计使然，因为 Update 只是更新 Bundle 本身，但不会触发解析所有其他依赖项的“更新”。因此，您必须在使用 refresh 命令自行解析捆绑包时触发该“更新”。这可以使用休眠捆绑包的 ID 或仅“刷新”来完成。第二个将更新您已安装的所有捆绑包的解析。
