Spring JMS接收主题消息

我正在编写一个简单的教程.我有一个发布者,它发送关于主题的消息和订阅者以接收它.当我启动应用程序时,Spring配置文件加载,然后我收到以下错误

    2011-10-20 21:50:39,340 DEBUG [org.springframework.jms.support.destination.JndiDestinationResolver] - Located object with JNDI name [Ratetopic]

为什么春天认为它应该是一个队列而不是主题

我的jndi文件看起来像这样

java.naming.factory.initial = org.apache.activemq.jndi.ActiveMQInitialContextFactory
java.naming.provider.url = tcp://localhost:61616
java.naming.security.principal=system
java.naming.security.credentials=manager
connectionFactoryNames = TopicCF
topic.Ratetopic = Ratetopic

spring配置文件是

ecurity.principal">systemecurity.credentials">managerdiobjectfactorybean">
    etopic"/>
    NowledgeModeName" value="AUTO_ACKNowLEDGE"/>

我的订阅者实现了MessageListener

@Override
public void onMessage(Message message) {
    try {
        // Get the data from the message
        BytesMessage msg = (BytesMessage) message;
        double newRate = msg.readDouble();
        // If the rate is at least 1 point lower than the current rate,then
        //recommend refinancing
        if ((currentRate - newRate) >= 1.0) {
            System.out.println(
                    "New rate = " + newRate + " - Consider refinancing loan");
        } else {
            System.out.println("New rate = " + newRate + " - Keep existing loan");
        }
        System.out.println("\nWaiting for rate updates...");
    } catch (Exception ex) {
        ex.printstacktrace(System.out);
        System.exit(1);
    }
}

public static void main(String argv[]) {

    ApplicationContext ctx = new ClasspathXmlApplicationContext("app-context.xml");

    try {
        // Run until enter is pressed
        BufferedReader stdin = new BufferedReader(new InputStreamReader(system.in));
        System.out.println("TBorrower application started");
        System.out.println("Press enter to quit application");
        stdin.readLine();
    } catch (IOException ioe) {
        ioe.printstacktrace();
    }
}

最佳答案

您尝试使用某个主题,但是您没有在DefaultMessageListenerContainer上设置pubSubDomain属性,它默认为“false”,这意味着点对点,这意味着队列而不是主题.因此,错误消息告诉您Ratetopic不是javax.jms.Queue.
