在应用程序中，您需要访问JMS规范之外的一些IBM MQ功能

IBM MQ v8知识中心在页面“Reading and writing the message descriptor from an IBM MQ classes for JMS application”中说明了如何使用IBM MQ类为JMS设置MQMD属性

You must set the Destination object property WMQ_MQMD_WRITE_ENABLED to true for the setting of MQMD properties to have any effect. You can then use the property setting methods of the message (for example setStringProperty) to assign values to the MQMD fields. All MQMD fields are exposed except StrucId and Version; BackoutCount can be read but not written to.

This example results in a message being put to a queue or topic with MQMD.UserIdentifier set to "JoeBloggs". // Create a ConnectionFactory, connection, session, producer, message // ...

// Create a destination
// ...

// Enable MQMD write
dest.setBooleanProperty(WMQConstants.WMQ_MQMD_WRITE_ENABLED, true);

// Optionally, set a message context if applicable for this MD field
dest.setIntProperty(WMQConstants.WMQ_MQMD_MESSAGE_CONTEXT, 
  WMQConstants.WMQ_MDCTX_SET_IDENTITY_CONTEXT);

// On the message, set property to provide custom UserId
msg.setStringProperty("JMS_IBM_MQMD_UserIdentifier", "JoeBloggs");

// Send the message
// ...

为了使用WMQ_MDCTX_SET_IDENTITY_CONTEXT，您需要向连接到IBM MQ队列管理器的用户授予OAM对qmgr对象和消息将queue的queue对象和queue上的PUT权限+setid，以及您将授予的任何正常权限（例如：qmgr或{}上的+put）
