尝试使用 Apache-Camel 读取文件时未找到文件异常

Question

我有以下代码，它从 windows 系统读取文件并将其放入 ibm-mq。我没有收到任何错误。但是当我在 IBM Queue 中检查消息时，我没有收到任何消息。

   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();
   }

我查看了控制台上的调试信息，我发现了类似

调试信息显示 "no such file or directory"。我认为这是权限错误，我尝试使用正常的 java 代码，代码能够成功读取文件。确切地说，我不知道问题出在哪里。是否遗漏了将文件放入 mq 的代码中的任何内容？？

Answer 1

你的uri应该是目录路径，没有文件名。您可以使用 fileName 选项指定文件名：

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