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 Service Mix Bundles）

Ref: Camel-UserForum-关于同一个问题

我花了很多时间（甚至几天）用 osgi 容器搜索/理解骆驼弹簧。对于像我这样的初学者来说，我没有找到一篇适用于某些设置或 github..etc 的好文章。

我们的骆驼弹簧应用程序运行良好。现在我们要迁移到像 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问题，但最终会遇到以下问题：

  1. 我不知道在哪里放置camel-spring xml上下文和路由文件（以前在具有NON-OSGi的类路径中）。所以它没有加载上下文获取文件未找到。

  2. 如果我把它放在下面，我知道它可能是错误的方式

    ClassPathXmlApplicationContext appContext = new ClassPathXmlApplicationContext(new String[] {"file:app-camel-spring.xml" }); 异常：org.springframework.beans.factory.parsing.BeanDefinitionParsingException：配置问题：无法找到 XML 模式命名空间的 Spring NamespaceHandler [ http://camel.apache.org/schema/spring] 违规资源：URL [file:app-骆驼-spring.xml]

即使使用 Spring DM 也不起作用

谢谢，

Update-1 1. 在论坛要求我查看 GEMINI Blueprint(GB) 之后，我现在正在与 GB 核对。但是我仍然遇到与 JAXB 错误相同的错误。

我现在正在使用：菲利克斯：

使用 Apache Karaf 4.0.8，因为 4.1.0 有问题，并且不支持该 Camel 版本。

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。因此强烈建议使用 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

如果我是正确的，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。

对于 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：

  • 服务/引用，使用引用事务管理器进行测试
  • 纲要性质
  • bean 方法上的 @Transactional 注释，它也正确地创建了事务方面

上面证明了它是可行的，并且应该允许大多数旧集成几乎开箱即用。蓝图也有可能的好处——比如能够使用 Spring Data（尚未测试），例如我也在研究的 mongo。

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。

它的工作要归功于 Claus 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拥护者，因为它有一些令人讨厌的限制，特别是如果您像我一样使用 Spring 十多年。

兼容层还不完善，因为：

  1. 它有一些非关键的错误——比如如果你用骆驼路由重新启动包，它将无法以一些“模板”bean注册错误开始，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"/>

  2. 我无法让 spring deployer 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 - 很高兴拥有。

此外，目前仅适用于 Spring 4 的 ActiveMQ 5 客户端存在问题，但 Red Hat 有一个解决方案，因为他们有自己的 ActiveMQ 客户端版本，似乎适用于 Spring 5。

综上所述，您应该很高兴在 Karaf 4.2.3 中使用 Spring 5 和 Camel。

更新

可悲的是，社区决定取消骆驼春对 karaf 的支持。Camel 3 弹簧组件不再工作，并且在类和资源加载时失败。

终于用 OSGi 离开了 Camel-Spring。这是一个噩梦组合尝试。这个组合有很多问题。

现在尝试骆驼+蓝图+卡拉夫。

感谢您的支持。
