骆驼码头使用Spring引导口

Question

我正在用apache Camel构建一个spring boot应用程序。我想让camel中的rest()DSL监听spring boot启动时的相同端口。

我尝试了这个链接，但如果不使用servlet组件，就无法解析它。我不希望我的路由看起来像servlet:/hello，而是希望直接使用jetty(jetty:http://0.0.0.0:0/hello)

如果您将Spring Boot设置为使用任何HTTP服务器(tomcat、jetty、undertow)，并且希望将其用作Camel Rest DSL的一部分，那么您应该使用camel-servlet-starter来使用servlet与Spring Boot HTTP服务器集成。
