如何解决 Apache Camel 中的“无法创建路由 route1 异常”?

Azh*_*l A 7 java apache-camel

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

谁能帮我解决这个问题?

这是示例代码和一个例外,

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));
