嘗試使用Apache-Camel讀取文件時發現文件未找到異常

Question

我有以下代碼從Windows系統讀取文件並將其放在ibm-mq中。 我沒有收到任何錯誤。 但是當我在IBM Queue中檢查消息時，我沒有任何消息。

   public class FileToJMS{ 

   public static void main(String args[]) throws Exception
   {
       final Map headers=new HashMap();
       headers.put("xxx","yy");
       headers.put("yyy","zzz");
       headers.put("xyz","1");
       CamelContext camelContext = new DefaultCamelContext();

        MQQueueConnectionFactory connectionFactory = new MQQueueConnectionFactory();
        connectionFactory.setHostName("zrled201");
    try {
            connectionFactory.setPort(1234);
            connectionFactory.setQueueManager("xxxxx");
            connectionFactory.setChannel("channel");
            connectionFactory.setTransportType(1);
        } catch (JMSException e) {
            e.printStackTrace();
        }
        camelContext.addComponent("wmq", JmsComponent.jmsComponentAutoAcknowledge(connectionFactory));

   try {
       camelContext.addRoutes(new RouteBuilder() {
           public void configure() throws Exception {
               from("file:C:/apche_camel/wmq_inputs/file_Name.xml?noop=true").process(new Processor() {
                   public void process(Exchange exchange) throws Exception {

                        exchange.getIn().setHeaders(headers);
                       }
                      })
                       .to("wmq:queue:ESB.ENTRY.SERVICE.IN");
               System.out.println("done");
           }
       });
   } catch (Exception e) {
       e.printStackTrace();
   }

   camelContext.start();
 Thread.sleep(10000);
   camelContext.stop();
   }

我已經在控制台上查看了調試信息，我發現了一些類似的東西

正如可以看到調試信息顯示“沒有這樣的文件或目錄”。 我認為這是權限錯誤，我嘗試使用普通的java代碼，代碼能夠讀取文件sucessfull。 我完全不知道問題出在哪里。 錯過了在mq中放置文件的代碼中的任何內容？

你擁有的uri應該是目錄路徑，沒有文件名。 您可以使用fileName選項指定文件名：

from("file:C:/apche_camel/wmq_inputs?fileName=file_Name.xml&noop=true")
