Sending complex object via JMS in Java
提问by ant
Is it possible to send complex messages via JMS? I can send TextMessages, Messages etc .. but when I try to send my custom object type MyObjecttrough send()method of MessageProducerI get compile error.
是否可以通过 JMS 发送复杂的消息？我可以发送 TextMessages、Messages 等......但是当我尝试发送我的自定义对象类型MyObject槽send()方法时，MessageProducer我得到了编译错误。
Then I tried to cast it, I get cast exception like MyObject cannot be cast to javax.jms.Message
然后我尝试投射它，我得到了投射异常 MyObject cannot be cast to javax.jms.Message
Here is a code I tried :
这是我试过的代码：
MessageProducer messageProducer = session.createProducer(destination);
messageProducer.send((Message)getMyObject()); //where getMyObject method retrieves mapped myObject type
anyone got any advice? thank you
有人有什么建议吗？谢谢

As long as your object is Serializable, you can use an ObjectMessage
只要您的对象是Serializable，您就可以使用ObjectMessage
MessageProducer producer = session.createProducer( destination );
ObjectMessage message = session.createObjectMessage( getMyObject() );
producer.send( message );

You have one of two problems:
您有以下两个问题之一：
- MyObject does not implement javax.jms.Message
- getMyObject does not return a MyObject (assuming that it does implement Message)
- MyObject 没有实现 javax.jms.Message
- getMyObject 不返回 MyObject（假设它确实实现了 Message）
