Tomcat ApacheCamelServlet HTTP代理

我试图在tomcat上使用ApacheCamel作为servlet实现http代理

当我使用camel作为独立应用程序时，Everythink运行良好：

public static void main(String[] args) throws Exception {
    CamelContext context = new DefaultCamelContext();
    ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("http://localhost:8000");
    context.addComponent("test-http", JmsComponent.jmsComponentAutoAcknowledge(connectionFactory));
    context.addRoutes(new Router());
    context.start();
}

static class Router extends RouteBuilder {
    @Override
    public void configure() throws Exception {
        from("jetty:http://localhost:8000/api2/data/").to("http://localhost:8080/api2/data/?bridgeEndpoint=true");
    }
}

但是如果我尝试在tomcat中作为servlet来做，我会在启动tomcat后立即出错

web.xml：

<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

  <display-name>LoadBalancer</display-name>

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:camel-config.xml</param-value>
  </context-param>
</web-app>

我建议您阅读官方文件。您没有将

？bridgeEndpoint=true

放在

到
camel config.xml
的
端点中，但它是在独立路径中，这正常吗？
