java - Spring应用程序不使用JmsTemplate退出

Question

我正在集成 Spring-4 和 Active-MQ 5.8。我写了一些小测试代码。它正确发送消息但不退出。

发件人代码是

package sample.jms.activemq;

import java.util.Map;

import org.springframework.jms.core.JmsTemplate;

public class MessageSender {

    private final JmsTemplate jmsTemplate;

    public MessageSender(final JmsTemplate jmsTemplate) {
        this.jmsTemplate = jmsTemplate;
    }

    public void send(final Map map) {
        jmsTemplate.convertAndSend(map);
    }

}

        AbstractApplicationContext context = new ClassPathXmlApplicationContext(
                "/sample/jms/resources/Spring-Module.xml");
        MessageSender sender = (MessageSender) context.getBean("messageSender");
        Map<String, String> map = new HashMap<String, String>();
        map.put("Name", "SampleName");
        sender.send(map);
        System.out.println("Exiting");
        context.registerShutdownHook();

    }
}

尝试将 tcp://queueURL:61616?daemon=true 添加到您的配置

JMS 只是不断监听消息，因此要关闭它应该是守护进程。
