简短的回答 - 是的。
当您下载并安装 WMQ 客户端 ( SupportPac MQC71 ) 时,除了 Java 类、诊断实用程序和大量示例代码之外,您还可以获得。在示例程序中,您会发现MQSample.java
如下所示:
import com.ibm.mq.MQException;
import com.ibm.mq.MQGetMessageOptions;
import com.ibm.mq.MQMessage;
import com.ibm.mq.MQPutMessageOptions;
import com.ibm.mq.MQQueue;
import com.ibm.mq.MQQueueManager;
import com.ibm.mq.constants.MQConstants;
public class MQSample {
public static void main(String args[]) {
try {
// 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 = MQConstants.MQOO_INPUT_AS_Q_DEF | MQConstants.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...");
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);
ex.printStackTrace();
for (Throwable t = ex.getCause(); t != null; t = t.getCause()) {
System.out.println("... Caused by ");
t.printStackTrace();
}
}
catch (java.io.IOException ex) {
System.out.println("An IOException occured whilst writing to the message buffer: " + ex);
}
return;
}
}
当然也有 JMS、C、C# 等的示例。显示的示例使用同步(阻塞)GET
调用,但如果您想使用回调机制实现,则可以使用异步侦听器方法。
我还建议查看信息中心的应用程序开发部分。 这些是 v7.0 文档,这些是 v7.1 文档。
