[英]Apache Camel on Karaf with Spring DSL + OSGi
我是 OSGI 世界的新手。
版本： Karaf：4.1.0 Camel：2.18.2 Spring：4.3.5_RELEASE_1（Apache 服务混合包）
我花了很多时间（甚至几天）用 osgi 容器搜索/理解camel-spring。 我没有找到适合像我这样的初学者的好文章，它适用于一些设置或 github.. 等。
我们的骆驼弹簧应用程序运行良好。 现在我们想转移到像 Karaf 这样的 OSGI 环境。 我们正在做一些迁移到 OSGI 的工作，我们遇到了一些严重的问题，我们能够解决其中的几个，但最终遇到了以下问题：
我不知道在哪里放置骆驼弹簧 xml 上下文和路由文件（以前在非 OSGi 的类路径中）。所以它没有加载上下文获取文件未找到。
如果我把它放在下面，我知道它可能是一种错误的方式
ClassPathXmlApplicationContext appContext = new ClassPathXmlApplicationContext( new String[] {"file:app-camel-spring.xml" }); 异常：org.springframework.beans.factory.parsing.BeanDefinitionParsingException：配置问题：无法为 XML 架构命名空间 [ http://camel.apache.org/schema/spring]找到 Spring NamespaceHandler 违规资源：URL [file:app-骆驼弹簧.xml]
即使使用 Spring DM 它也不起作用
谢谢，
Update-1 1. 在论坛要求我查看 GEMINI Blueprint(GB) 之后，我现在正在查看 GB。 但是我仍然遇到与 JAXB 错误相同的错误。
我现在正在使用：Felix：

使用 Apache Karaf 4.0.8，因为 4.1.0 有问题，该 Camel 版本不支持。
并且 spring XML 文件应该是文件夹中的占位符，如该示例所示，例如META-INF/spring 。
但请注意 Spring DM 已被弃用且已死。 因此强烈建议改用 OSGi Blueprint。
并且在未来，Karaf 将拥有某种 spring XML 到蓝图 XML 自动转换器，因此它可以像运行蓝图一样运行 spring xml 文件。 但有关该问题的更多详细信息，请访问 Karaf 社区。
[caused by: Unable to resolve camel-spring-dm/2.18.2: missing requirement
[camel-spring-dm/2.18.2] osgi.identity; osgi.identity=spring-dm;
错误很明显，功能解析器找不到spring-dm功能，需要先安装
feature:install spring-dm
如果我是对的，karaf 放弃了对 spring-dm 的支持，因此该功能可能不可用，您需要手动安装 spring-dm。 但是就像已经说过的那样，spring-dm 已被弃用，并且是在 OSGi 环境中使用 spring 的一种非常错误的方式。 你应该转向 aries 蓝图，或者如果 spring 真的不可或缺，你应该使用 gemini-blueprint，它是一个与 Spring 4.2.x 兼容的蓝图实现。
https://eclipse.org/gemini/blueprint/ http://www.eclipse.org/gemini/blueprint/documentation/migration/
终于用 OSGi 离开了 Camel-Spring。 它是一个噩梦组合尝试。 这种组合有很多问题。
现在尝试骆驼+蓝图+卡拉夫。
感谢您的支持。
使用 Karaf 4.2.3、Camel 2.22.3 和 Spring 5.1，它的工作方式与旧的 spring-dm 和 Spring 3.2 一样。 它适用于我多年前为 Spring 3.2 和 Spring DM 制作的旧集成，使用：
以上证明它是可行的，并且应该允许大多数旧的集成几乎开箱即用。 蓝图也有可能的好处——比如能够使用 Spring Data（尚未测试），例如 mongo，我也在研究。
显然，您需要使用新的依赖项重新编译您的项目以使您的清单正确。
它的工作归功于 Claus 所提到的 - Spring to Blueprint 兼容层。 提供此功能的特性称为“aries-blueprint-spring”。 我还没有在现实生活中使用它，但我正在研究如何将我们的 Spring 集成从 Karaf 2（Fuse 6.3）迁移到 Karaf 4（Fuse 7.2）。 我个人不是蓝图的忠实粉丝，因为它有一些恼人的限制，特别是如果你像我一样使用 Spring 已经十多年了。
兼容层还不完善，因为：
它有一些非关键的错误——比如如果你用骆驼路线重新启动包，它会以一些“模板”bean 注册错误开始失败，我相信社区会在某个时候解决这个问题。 这似乎与十年前完成的这个问题有关： https : //issues.apache.org/jira/browse/CAMEL-1899其中 Camel 添加了一些额外的 bean，这些 bean 是为了改进单元测试而创建的。 您可以通过添加到 Spring Context 来解决它，直到修复它：
<bean id="template" class="java.lang.String"/> <bean id="fluentTemplate" class="java.lang.String"/> <bean id="consumerTemplate" class="java.lang.String"/>我无法让 spring 部署程序工作 - 将原始 Spring XML 部署为包，就像我们用于包的 JDBC 连接池一样。 但这是一种利基方法 - 很好。
此外，目前仅适用于 Spring 4 的 ActiveMQ 5 客户端存在问题，但 Red Hat 提供了解决方案，因为他们拥有自己的 ActiveMQ 客户端版本，似乎适用于 Spring 5。
有了以上所有内容，您应该很高兴在 Karaf 4.2.3 中使用 Spring 5 和 Camel。
更新
可悲的是，社区决定取消对 karaf 的骆驼弹簧支持。 Camel 3 spring 组件不再工作并且无法加载类和资源。
Karaf适用于春季骆驼路线，但不适用于Java DSL骆驼路线
