调用主类

Question

我创建了一个端点`直接骆驼路线骆驼路线终点：getRestFromExternalService，当我尝试在主要的方法来使用这个端点另一个类中我得到一个异常

交换[ID-WMLI118067-61025-1493883025815-0-2]

和

没有消费者对端点可用：在交易所执行过程中发生的异常端点[直接： // getRestFromExternalService。交换[ID-WMLI118067-61025-1493883025815-0-2]

这是路由类：

public class MyRoute extends RouteBuilder { 

@Override 
public void configure() throws Exception { 

    // Create the camel context for the REST API routing in Fuse 
      CamelContext contextFuseAPI = new DefaultCamelContext(); 

      // Start the route inside the context to listen to the ActiveMQ 
      contextFuseAPI.addRoutes(new RouteBuilder() { 

       @Override 
       public void configure() { 
        from("direct:getRestFromExternalService") 
         .setHeader(Exchange.HTTP_METHOD, simple("GET")) 
         .to("<external API URI>"); 
       } 
}); 
} 
} 

这是与调用该路由main方法的类：

public class FuseApp { 

public static void main(String[] args) throws Exception { 
    CamelContext contextFuseAPI = new DefaultCamelContext(); 

    contextFuseAPI.addRoutes(new MyRoute()); 

    contextFuseAPI.start(); 

    Thread.sleep(3000); 

    ProducerTemplate template = contextFuseAPI.createProducerTemplate(); 

    Object result = template.requestBody("direct:getRestFromExternalService", null, String.class); 


    Exchange exchange = new DefaultExchange(contextFuseAPI); 
    String response = ExchangeHelper.convertToType(exchange, String.class, result); 
    System.out.println("Response : "+ response);   

    contextFuseAPI.stop(); 


} 

} 

我测试了没有ProducerTemplate和Object行的主要方法，它运行。有没有办法使用不同类中实现的路由与端点调用requestBody？

我解决了这个问题，问题是在路由类和main方法类中都创建了上下文。
