Java 是否可以将多个捆绑包部署到使用Hibernate Envers的ServiceMix？
我们正试图在ServiceMix 6.1.4中部署多个捆绑包，每个捆绑包都对数据库进行更新，我们希望这些更新能够通过Hibernate Envers 4.3.6.FINAL进行审核。我们正处于概念验证阶段，因此我们只构建jar文件，并将其放入apache-servicemix-6.1.4目录的deploy目录中，每个文件都有一个单独的数据源蓝图文件 单独而言，捆绑包可以正常工作并进行审计。但如果您同时部署了两个捆绑包，其中一个将失败并出现错误：Java 是否可以将多个捆绑包部署到使用Hibernate Envers的ServiceMix？,java,apache-karaf,hibernate-envers,apache-servicemix,Java,Apache Karaf,Hibernate Envers,Apache Servicemix,我们正试图在ServiceMix 6.1.4中部署多个捆绑包，每个捆绑包都对数据库进行更新，我们希望这些更新能够通过Hibernate Envers 4.3.6.FINAL进行审核。我们正处于概念验证阶段，因此我们只构建jar文件，并将其放入apache-servicemix-6.1.4目录的deploy目录中，每个文件都有一个单独的数据源蓝图文件 单独而言，捆绑包可以正常工作并进行审计。但如果您同时部署了两个捆绑包，其中一个将失败并出现错误： 2018-04-20 14:00:10,635 |

如果只有一个包可以使用Envers，那么我们必须开发一个额外的包来更新数据库，但是如果包可以是自包含的，那就更好了。您使用
<bean id="integrator" class="org.hibernate.envers.event.spi.EnversIntegrator" />
<service ref="integrator" interface="org.hibernate.integrator.spi.Integrator" />
由于这是一个OSGi服务，所以所有捆绑包都将使用它。因此，最后开始的包将同时看到和抱怨。试着把它放在自己的包中，确保它只注册一次。所以，本质上，答案是否定的？它不能在单个捆绑包内完成，我们需要一个单独的捆绑包来注册此服务？
