我正在尝试将deliveryMode显式设置为NONPERSISTENT并将其发送到ActiveMQ。
这是我的Spring JMS配置:
<?xml version="1.0" encoding="UTF-8"?>

<property name="defaultDestination" ref="defaultDestination" />
<property name="deliveryPersistent" value="false"/>
<property name="deliveryMode" value="1"/>
<property name="timeToLive" value="10000"/>
</bean>
<!-- =============================================== -->

class="org.springframework.jms.config.DefaultJmsListenerContainerFactory">

<property name="concurrency" value="3-10"/>
</bean>
</beans>
而我的制片人:
@Component
public class JmsMessageSender {
private final Logger log = Logger.getLogger(JmsMessageSender.class.toString());
@Autowired
private JmsTemplate jmsTemplate;
public void send(final Destination dest, final String text) {
this.jmsTemplate.send(dest, session -> {
Message message = session.createTextMessage(text);
log.info("delivery mode {" + jmsTemplate.getDeliveryMode() + "}, timeToLive {" + jmsTemplate.getTimeToLive() + "}");
return message;
});
}
}
发送时，我在控制台日志中看到:
INFO: Established shared JMS Connection: ActiveMQConnection {id=ID:localhost-61129-1458640452010-1:1,clientId=null,started=false}
mar 22, 2016 10:54:12 AM com.app.JmsMessageSender lambda$send$1
INFO: delivery mode {1}, timeToLive {10000}
mar 22, 2016 10:54:12 AM com.app.JmsMessageSender lambda$send$1
INFO: delivery mode {1}, timeToLive {10000}
这意味着转换模式设置为NONPERSISTENT。
但是，当我打开ActiveMQ WebConsole时-有标记为Persistent的消息。
有人可以解释一下为什么吗？如何解决这个问题？
最佳答案
请参阅the documentation-您必须通过将explicitQosEnabled设置为true来启用QOS设置(例如持久性)。
javadoc中还针对setDeliveryPersistent提到了这一点。
