Question

我目前有一个camel路由设置为从activemq主题中获取内容，将其传递给.xsl进行转换，然后将其传递给另一个activemq主题。我现在唯一的问题是我不确定如何实际将xml文件发布到队列中，以便开始整个过程。

我想过用一个字符串发送整个东西，但我不确定是否会被xsl文件拾取来转换它。如果有人有任何提示或方法将xml文件发送到activemq队列或主题，我们将非常感谢您的帮助！

谢谢！

Answer 1

1） ActiveMQ附带一个Web控制台，您可以在其中将消息发送到队列或主题。

默认情况下可以使用此控制台

http://localhost:8161/admin

ActiveMQ发行版中有一个WebConsole自述文件，提供了更多详细信息。

2）您也可以从JConsole发送消息（例如JMX）。

3）另一种方法是使用Camel路由，它从文件目录中消耗并发送到主题。然后你可以将文件放在目录中，让Camel拾取并发送文件。

<route>
  <from uri="file:somedir/inbox"/>
  <to uri="activemq:topic:someTopicName"/>
</route>

    Please refer the below code.
    Here we will receive message simple file creation then writing bytes coming from BytesMessageObject until EOF occurs.
                BytesMessage bm = (BytesMessage)topicSubscriber.receiveNoWait(); // receive(1000);
                    System.out.println("bm-->"+bm);
                    if(bm !=null){
                     File file = new File("D:/jms/myfie.txt"); //file created
                     FileOutputStream fos = new FileOutputStream(file);//create fileoutput stream
                     BufferedOutputStream outBuf = new BufferedOutputStream(fos);//create bufferoutputstream
                     int i;
                     while((i=bm.readInt())!=-1)//read unitil EOF means -1
    {
                        outBuf.write(i);//write it to the file
                     }
                     System.out.println("outBuf-->"+outBuf);
                     System.out.println(file.isFile());
                     outBuf.close();//close output buffer
                     fos.close();//close file ouput stream
                    }

    Here the file is opened then
    Wrote in BytesMessageObject.
    Sent Across the Queue            

                Sender code :

                File f=new File("D:/Import.txt");//get  file handle
                          System.out.println("is File "+f.isFile());
                          BytesMessage bm = topicSession.createBytesMessage();//create bytes message
                          InputStream in= new FileInputStream(f);//create input stream with file handle
                          BufferedInputStream inBuf= new BufferedInputStream(in);//create buffer input stream
                          int i;
                          while((i=inBuf.read())!=-1)//read file until EOF(-1)  is reached{
                             bm.writeInt(i);//write in bytesmessage
                          }
                          System.out.println("after while");
                          //adding an eof
                          bm.writeInt(-1);//add EOF in bytes message
                          System.out.println("BM = "+bm);
                          topicPublisher.send(bm);///send the bytes message
                          System.out.println("sent successfully");
                          topicConnection.stop();//stop connection
