Java 中使用websphere MQ

  【IT168 技术文档】websphere mq : 用于传输信息 具有跨平台的功能。

  1 安装websphere mq 并启动

  2 websphere mq 建立 queue Manager (如:MQSI_SAMPLE_QM)

  3 建立queue 类型选择 Local类型 的 (如lq )

  3 建立channels 类型选择Server Connection (如BridgeChannel)

  java 代码如下:

  package test.mq;   import com.ibm.mq.*;   /*   * 成功的访问mq 的java 类   */   public class FirstMqTest {   // public static void main(String[] args[]){   // FirstMqTest first = new FirstMqTest();   // first.test();   // }   public static void main(String args[]){   FirstMqTest first = new FirstMqTest();   first.test();   }   public void test(){   String qManager = "MQSI_SAMPLE_QM"; //QueueManager name   String qName = "lq";//Queue Name   try {   //configure connection parameters   MQEnvironment.hostname="172.16.17.123";//MQ Server name or IP   //MQEnvironment.port=1414;//listenr port   MQEnvironment.channel="BridgeChannel";//Server-Connection Channel   MQEnvironment.CCSID =1381;   // Create a connection to the QueueManager   System.out.println("Connecting to queue manager: "+qManager);   MQQueueManager qMgr = new MQQueueManager(qManager);   // Set up the options on the queue we wish to open   int openOptions = MQC.MQOO_INPUT_AS_Q_DEF | MQC.MQOO_OUTPUT;   // Now specify the queue that we wish to open and the open options   System.out.println("Accessing queue: "+qName);   MQQueue queue = qMgr.accessQueue(qName, openOptions);   // Define a simple WebSphere MQ Message ...   MQMessage msg = new MQMessage();   // ... and write some text in UTF8 format   msg.writeUTF("Hello, World!");   // Specify the default put message options   MQPutMessageOptions pmo = new MQPutMessageOptions();   // Put the message to the queue   System.out.println("Sending a message...");   /*   * 在此测试一下 mq 的传输次列   *   */   for(int j=0;j< 5;j++){   String str ="test11111111111";   str = str+j;   msg.writeUTF(str);   queue.put(msg, pmo);   }   queue.put(msg, pmo);   // Now get the message back again. First define a WebSphere MQ message   // to receive the data   MQMessage rcvMessage = new MQMessage();   // Specify default get message options   MQGetMessageOptions gmo = new MQGetMessageOptions();   // Get the message off the queue.   System.out.println("...and getting the message back again");   queue.get(rcvMessage, gmo);   // And display the message text...   String msgText = rcvMessage.readUTF();   System.out.println("The message is: " + msgText);   // Close the queue   System.out.println("Closing the queue");   queue.close();   // Disconnect from the QueueManager   System.out.println("Disconnecting from the Queue Manager");   qMgr.disconnect();   System.out.println("Done!");   }   catch (MQException ex) {   System.out.println("A WebSphere MQ Error occured : Completion Code "   + ex.completionCode + " Reason Code " + ex.reasonCode);   }   catch (java.io.IOException ex) {   System.out.println("An IOException occured whilst writing to the message buffer: "   + ex);   }   }   }
