Camel Daemon不会解析端点

Question

我有一个使用xslt组件的camel上下文。当我在本地开发机器上运行我的路由时，我没有遇到任何问题。

但是，当我在远程服务器上部署我的项目时，我遇到了一些xslt组件的问题。我对项目进行了后台管理，这样我就可以在后台运行了，也许这会导致问题？我检查了xsl文件的路径(测试了我日志中的路径)，它们是正确的，我甚至使用了绝对路径。

有谁有什么建议吗？或者知道为什么会出问题？

错误日志记录了以下错误：

Answer 1

我找到问题了。

我正在将这个旧的camel项目转换为作为守护进程运行。因为这个项目是mavenized的，所以我相信每个库都是远程获取的。显然，pom还包含一个指向本地库的路径，该库包含在项目的git repo中。缺少的实际jar是XSLT组件所需的Saxon jar。

因此，当我在本地运行该项目时，我没有遇到任何问题，因为jar就在那里。但是，当我构建和部署jar时，并没有包含Saxon jar。

我的解决方案是：

我向Nexus服务器添加了一个新的托管存储库，并将该依赖项包含到pom文件中。因此，不再有本地依赖项。
