java - 如何解决 Apache Camel 中的 "Failed to create route route1 exception"？

Question

我是 Apache Camel 概念的新手。我尝试使用 apache camel API 编写示例代码 并且在尝试运行代码时出现以下异常。

谁能帮我解决这个问题？

这是示例代码和异常，

示例代码:

 CamelContext context = new DefaultCamelContext();
 context.addRoutes(new RouteBuilder() { 
  public void configure() {
    from("direct:start")
    .setHeader(Exchange.HTTP_URI,simple("`http://sample-host:8080/demo/get`"))
    .to("http://emptyhost");
  }
 });
 context.start();
 ProducerTemplate template = context.createProducerTemplate();
 System.out.println(template.requestBodyAndHeaders("direct:start", null, null,String.class));

异常:

Exception in thread "main" org.apache.camel.FailedToCreateRouteException: 
Failed to create route route1 at: 
    >>> To[`http://sample-host:8080/demo/get`] <<< 
in route: Route(route1)
    [[From[direct:start]] -> [`To[http://sample-host:8`…
because of 
    Failed to resolve endpoint: `http://sample-host:8080/demo/get`
due to:

依赖库丢失。所以我添加了这些库并解决了我的问题。
