如何组织一个大的 karaf blueprint.xml？

Question

我有一个 blueprint.xml 用于在 Servicemix 下的 Karaf 3.5.6 中部署的骆驼应用程序，它看起来有点类似于下图所示：-

</blueprint>

在蓝图中，我们定义了不同的工作流模块（例如在上面的blueprint.xml - order & ERP 中）。现在我们有一个blueprint.xml，我们在其中定义了我们所有的工作流程。这已经变得相当大了（已经有大约 1000 行，我们将添加更多）。

谁能告诉我

1. 人们如何像上面那样组织大型blueprint.xml？
2. 是否可以有不同的 xml（例如，在我的情况下，order 和 erp 模块的不同 xml）和结合所有子 xml 的单个母 xml？

Bundle 引用的蓝图文件中的所有元数据都被加载并合并在一起：

• 您可以将此文件拆分为几个小文件
• 我通常按主题拆分定义：在您的情况下，可能一个文件包含骆驼路线，另一个文件包含来自 ConfigurationAdmin 的配置等
• Aries-Blueprint 有一个带有内省/注释的扩展，可以帮助调整此类文件的大小
