Java Spring-jms-messageId分隔符

我正在使用

@JmsListener

注释从队列接收所有消息

@JmsListener(destination = MyQueue, selector = "MAINST = '" + instanceName + "'")
            public void receivMsg(Message message) {

---

但是另一个系统不能处理消息属性。它以相关id响应。我如何通过CorrelationID过滤消息，当在

LinkedList

中存在时，您可以使用该标头属性的名称通过JMS相关id进行选择：

selector = "JMSCorrelationID = '" + something + "'"

---

同时签出消息API的消息选择器部分：

为

instanceName

使用属性占位符。下面是一个在同一队列上有两个侦听器的示例

@SpringBootApplication
public class So48377178Application {

    public static void main(String[] args) {
        SpringApplication.run(So48377178Application.class, args);
    }

    @Bean
    public ApplicationRunner runner(JmsTemplate template) {
        return args -> {
            template.convertAndSend("foo", "This one's for A", m -> {
                m.setJMSCorrelationID("A");
                return m;
            });
            template.convertAndSend("foo", "This one's for B", m -> {
                m.setJMSCorrelationID("B");
                return m;
            });
        };
    }

    @JmsListener(destination = "foo", selector = "JMSCorrelationID='${a.instance}'")
    public void listenA(Message message) {
        System.out.println("A: " + message);
    }

    @JmsListener(destination = "foo", selector = "JMSCorrelationID='${b.instance}'")
    public void listenB(Message message) {
        System.out.println("B: " + message);
    }

}

与

它不起作用。因为“某物”必须是字符串constantAh，好的，是的。订户和相关ID是一个相当重的对象。不需要为每条消息（或相关ID）创建一个。如果不需要的话，你就不能把它们扔掉吗？类似于：if（！msg.getJMSCorrelationID（）.equals（Something））返回；因为另一个应用程序也侦听此队列。使用主题如何？
