我有一个 blueprint.xml 用于部署在 Karaf 3.5.6 下的 Servicemix 下的 camel 应用程序，它看起来有点类似于下面显示的内容:-

在蓝图中，我们定义了不同的工作流程模块(例如在上面的 blueprint.xml - order 和 ERP 中)。现在我们只有一个 blueprint.xml，我们在其中定义所有工作流。这已经变得相当大了(已经有大约 1000 行，我们将添加更多)。
谁能告诉我一下
- 人们如何组织像上面那样的大型
blueprint.xml？ - 是否可以有不同的 xml(例如，在我的例子中，
order和erp模块有不同的 xml)和一个包含所有子 xml 的单一母 xml ？
最佳答案
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:
- 你可以把这个文件分成几个小文件
- 我通常按主题拆分定义:在您的情况下，可能一个文件带有 Camel 路线，另一个文件带有来自 ConfigurationAdmin 的配置，等等
- Aries-Blueprint 有一个带有内省(introspection)/注释的扩展，可以帮助减小此类文件的大小
关于xml - 如何组织一个大的karaf blueprint.xml？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36157693/
