我使用Wildfly 10.0.0最終獨立部署，EJB，Hibernate開發了一個Web應用程序。我提到並創建了MDB，MessageProducerBean（@RequestScoped），隊列和的ConnectionFactory。我可以在MDB中收到。如何發送消息和通知給特定用戶和所有用戶使用JMS和MDB？
我的問題是我的應用程序可以被許多用戶訪問。我需要發送一些消息給特定的用戶（例如：用戶A）和一些消息給所有用戶。
如果我們使用可以發送給一個客戶端的Queue，我閱讀了一些有這方面知識的文章，如果我們使用Topic，我們可以發送給許多客戶端，但是我對此沒有清楚的想法。而我的下一個問題是這個消息只有在用戶處於活動狀態時才起作用
我需要隨時發送消息，不管他們是否在線。如果他們在離線後登錄按摩應顯示。任何人都可以幫忙嗎？ 我將在下面總結我的問題。
1）需要用戶發送消息和通知。
2）需要保持所有消息，甚至用戶離線。
這裏是我的代碼

提前感謝！
感謝您的寶貴迴應。你能用同樣的示例消息屬性來幫助我嗎？ – coolSmart
消息msg = session.createTextMessage（messageToSend）; msg.setStringProperty（「user.name」，「ssosna」）; msg.setStringProperty（「host.name」，「mydesktop」）; –
謝謝@Scott Sosna的幫助。 – coolSmart
