我试图构建骆驼 sql 应用程序，但我有堆栈。

我在页面中找到了有关 camel-sql 的信息http://camel.apache.org/sql-component.html。

我已经创建了 xml 配置，如示例所示，在我的 FUSE ESB 中我发现了异常：

    org.springframework.beans.factory.BeanCreationException: Error creating bean with name
     'camel-21': Invocation of init method failed; nested exception is 
    org.springframework.beans.factory.CannotLoadBeanClassException: 
Cannot find class [org.springframework.jdbc.datasource.DriverManagerDataSource] 
for bean with name 'esb' defined in URL [bundle://249.2:0/META-INF/spring/camel-context.xml]; nested exception is java.lang.ClassNotFoundException: 
org.springframework.jdbc.datasource.DriverManagerDataSource not found from bundle [camel]

但在我的保险丝控制台中，我有弹簧 jdbc：

karaf@root> osgi:list | grep Spring

我需要做什么 ？

更新：

但是当我使用 osgi:headers 时，我看不到导入的类，我的 pom.xml 有什么问题？

osgi：标题：

OSGi 对于轻松安装和使用 JDBC 驱动程序可能有点麻烦。一个经过验证的解决方案是将 JDBC 驱动程序作为片段包安装到您的包中。

它已在 FuseSource 论坛上进行了讨论，其中有如何解决此问题的说明。起点是此链接： http://fusesource.com/forums/thread.jspa?messageID=13043& #13043，然后按照其他讨论的参考资料了解更多详细信息以及如何解决它。

你应该确保你的路由在org.springframework.jdbc.datasource上有一个导入包。您可以使用karaf中的header命令对其进行验证。

好的，我找到了解决方案。

这很容易——我只需要安装 mysql 连接器。

谢谢大家。
