【问题描述】：

我正在尝试将 jetty 组件与 apache camel 一起使用，并简单地打印一条“Hello World”消息。但是我遇到了一个错误，上面写着 -> 无法解析端点：jetty://http://localhost:8888/sample，原因是：没有找到带有方案的组件：jetty，即使我在 pom.xml 中添加了对码头的依赖。请告诉我我做错了什么。下面是我的代码和pom文件

package com.rama.example;

import org.apache.camel.CamelContext;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.impl.DefaultCamelContext;

public class JettyGreeting {
public static void main(String[] args) throws Exception {

    CamelContext context = new DefaultCamelContext();
    context.addRoutes(new RouteBuilder() {

        @Override
        public void configure() throws Exception {
            // TODO Auto-generated method stub



    from("jetty:http://localhost:8888/sample")
    .log("Received a request")
    .setBody(simple("Hello, World"));


}
}); 
while(true)
    context.start();
}

}

【解决方案1】：

您在 pom.xml 文件中将骆驼码头作为测试范围。删除它，让码头成为您应用程序的一部分。
