[英]Spring JMS - Unable to connect to broker URL with embedded Broker
這是我的 JmsMessageSender
@Service
public class JmsMessageSender {
@Autowired
private JmsTemplate jmsTemplate;
/**
* send text to default destination
* @param text
*/
public void send(final String text) {
this.jmsTemplate.send(new MessageCreator() {
@Override
public Message createMessage(Session session) throws JMSException {
Message message = session.createTextMessage(text);
return message;
}
});
}
/**
* Simplify the send by using convertAndSend
* @param text
*/
public void sendText(final String text) {
this.jmsTemplate.convertAndSend(text);
}
/**
* Send text message to a specified destination
* @param text
*/
public void send(final Destination dest,final String text) {
this.jmsTemplate.send(dest,new MessageCreator() {
@Override
public Message createMessage(Session session) throws JMSException {
Message message = session.createTextMessage(text);
return message;
}
});
}
}
這是我的 DemoClass
public class DemoMain {
public static void main(String[] args) {
// init spring context
ApplicationContext ctx = new ClassPathXmlApplicationContext("context.xml");
// get bean from context
JmsMessageSender jmsMessageSender = (JmsMessageSender)ctx.getBean("jmsMessageSender");
// send to default destination
jmsMessageSender.send("hello JMS");
// send to a code specified destination
Queue queue = new ActiveMQQueue("AnotherDest");
jmsMessageSender.send(queue, "hello Another Message");
// close spring application context
((ClassPathXmlApplicationContext)ctx).close();
}
}
我的上下文.xml
和我的 activemq.xml 配置。

For better performances use VM cursor and small memory limit.
For more information, see:

The managementContext is used to configure how ActiveMQ is exposed in
JMX. By default, ActiveMQ uses the MBean server that is started by
the JVM. For more information, see:
http://activemq.apache.org/jmx.html
-->
<managementContext>
<managementContext createConnector="false"/>
</managementContext>
<!--
Configure message persistence for the broker. The default persistence
mechanism is the KahaDB store (identified by the kahaDB tag).
For more information, see:
http://activemq.apache.org/persistence.html
-->
<persistenceAdapter>
<kahaDB directory="activemq-data/kahadb"/>
</persistenceAdapter>
<!--
The systemUsage controls the maximum amount of space the broker will
use before slowing down producers. For more information, see:
http://activemq.apache.org/producer-flow-control.html
If using ActiveMQ embedded - the following limits could safely be used:
<systemUsage>
<systemUsage>
<memoryUsage>
<memoryUsage limit="20 mb"/>
</memoryUsage>
<storeUsage>
<storeUsage limit="1 gb"/>
</storeUsage>
<tempUsage>
<tempUsage limit="100 mb"/>
</tempUsage>
</systemUsage>
</systemUsage>
-->
<systemUsage>
<systemUsage>
<memoryUsage>
<memoryUsage limit="64 mb"/>
</memoryUsage>
<storeUsage>
<storeUsage limit="100 gb"/>
</storeUsage>
<tempUsage>

<!--
The transport connectors expose ActiveMQ over a given protocol to
clients and other brokers. For more information, see:
http://activemq.apache.org/configuring-transports.html
-->
<transportConnectors>
<!-- DOS protection, limit concurrent connections to 1000 and frame size to 100MB -->
<transportConnector name="openwire" uri="tcp://0.0.0.0:61616?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/>

<shutdownHooks>
<bean xmlns="http://www.springframework.org/schema/beans" class="org.apache.activemq.hooks.SpringContextHook" />
</shutdownHooks>
</broker>
</beans>
但是,當我運行主類時,會顯示此錯誤。 我錯過了配置中的任何內容嗎?
Caused by: javax.jms.JMSException: Could not connect to broker URL: tcp://192.168.203.143:61616. Reason: java.net.ConnectException: Connection timed out: connect
您是否在 tcp://192.168.203.143:61616 上啟動了 AMQ 代理? 如果沒有,那么啟動它應該可以解決問題。
有類似的錯誤。 這里的解決方案。
嘗試通過您的 IP 地址連接到 borker 無法連接到代理 URL:tcp://192.168.203.143:61616。 上面提到的 ip 地址與示例系統有關。
嘗試為您的 ip 地址運行相同的代碼。(在網絡設置或命令“ipconfig”中知道您的 ipAddress)
無法連接到代理 URL:tcp://192.168.1.184:61616。
