Question

我正在使用Apache Camel来构建代理。我能够运行提供的样本。但是我必须手动配置camel-config.xml文件。我想知道我们是否可以通过编程方式配置此文件以在运行时托管/配置代理？

这是原始的camel-config.xml文件：

此camel-config文件用于设置ApplicationContextUri，如下所示：

Main main = new Main();
main.setApplicationContextUri("/ApacheCamelTest2/camel-config.xml");
main.start();

如何在运行时以编程方式配置camel-config.xml？

Answer 1

使用DSL并在运行时创建它们。 https://camel.apache.org/java-dsl.html 这样您就可以完全控制路径，并且可以在运行时以编程方式添加/修改/删除它们。
