Apache Camel：使用jetty使用rest服务

Question

我想用apache-camel使用Jetty在http://localhost:8080/中并发一个rest服务。但是这段代码不会对API产生任何请求。我是apache-camel的初学者，我想使用不同的微服务。

package example;

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



public class ejemplo {

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



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

            @Override
            public void configure() throws Exception {

                from("direct:start")
                .log("Http Route started")
                .setHeader(Exchange.HTTP_METHOD,simple("GET"))
                .setHeader(Exchange.CONTENT_TYPE,simple("application/json"))
                .to("jetty:http://0.0.0.0:8080/")
                .process(new Processor(){

                    public void process(Exchange exchange) throws Exception {
                        System.out.println("I am a process....");
                        String msg = exchange.getIn().getBody().toString();
                        System.out.println(msg);

                    }

                });

            }

        });

        context.start();

    }

}

此输出不产生LocalHost:8080中API的任何响应，但我认为路由是正确的。我想知道是否有其他方法使用Apache-Camel使用API rest的rest服务。

请注意，start只是一个名称，而direct组件允许您从其他路由同步调用您的路由，您似乎并不是这样做的

若要检查路由是否正确，请在fromendpoint到计时器中替换Direct，例如from（“Timer：//foo？fixedrate=true&period=10000”），有关详细信息，请参阅camel docs
