調用主類

Question

我創建了一個端點`直接駱駝路線駱駝路線終點：getRestFromExternalService，當我嘗試在主要的方法來使用這個端點另一個類中我得到一個異常

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

和

沒有消費者對端點可用：在交易所執行過程中發生的異常端點[直接： // getRestFromExternalService。交換[ID-WMLI118067-61025-1493883025815-0-2]

這是路由類：

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>"); 
       } 
}); 
} 
} 

這是與調用該路由main方法的類：

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(); 


} 

} 

我測試了沒有ProducerTemplate和Object行的主要方法，它運行。有沒有辦法使用不同類中實現的路由與端點調用requestBody？

我解決了這個問題，問題是在路由類和main方法類中都創建了上下文。
