【问题描述】：
我正在尝试使用 hornetq 核心 API 和 spring 来定义 hornetq 客户端，这将是 HA。 但是当我停止实时服务器并且备份服务器变为“实时”时，客户端失败并出现连接错误。知道我做错了什么吗？
我定义了集群的独立 hornetq 服务器（没有组或发现）。 hornetq-configuration.xml：
...
<connectors>
<connector name="netty">
<factory-class>org.hornetq.core.remoting.impl.netty.NettyConnectorFactory</factory-class>
<param key="host" value="${hornetq.remoting.netty.host:live-host}"/>
<param key="port" value="${hornetq.remoting.netty.port:5445}"/>
</connector>
<!-- Connector to this server.s backup. This is needed for failback to work properly in a static cluster -->
<connector name="netty-backup">
<factory-class>org.hornetq.core.remoting.impl.netty.NettyConnectorFactory</factory-class>
<param key="host" value="${hornetq.remoting.netty.host:backup-host}"/>
<param key="port" value="${hornetq.remoting.netty.port:5446}"/>
</connector>
<cluster-connections>
<cluster-connection name="my-cluster">
<address>jms</address>
<connector-ref>netty</connector-ref>
<retry-interval>500</retry-interval>
<use-duplicate-detection>true</use-duplicate-detection>
<forward-when-no-consumers>false</forward-when-no-consumers>
<max-hops>1</max-hops>
<static-connectors>
<!-- Without this the connection factory won.t be able to reconnect on failback -->
<connector-ref>netty-backup</connector-ref>
</static-connectors>
</cluster-connection>
...
我定义了hornetq客户端：
@Test
public void testHA() throws InterruptedException, IOException{
List<TransportConfiguration> transportConfigurationList = new ArrayList<TransportConfiguration>();
Map<String, Object> transportProperties = new HashMap<String, Object>();
transportProperties.put("host", "live-server");
transportProperties.put("port", 5445);
transportConfigurationList.add(new TransportConfiguration("org.hornetq.core.remoting.impl.netty.NettyConnectorFactory", transportProperties));
transportProperties = new HashMap<String, Object>();
transportProperties.put("host", "backup-server");
transportProperties.put("port", 5446);
transportConfigurationList.add(new TransportConfiguration("org.hornetq.core.remoting.impl.netty.NettyConnectorFactory", transportProperties));
HornetQJMSConnectionFactory connectionFactory = new HornetQJMSConnectionFactory(true, transportConfigurationList.toArray(new TransportConfiguration[2]));
JmsTemplate producer = new JmsTemplate(connectionFactory);
producer.send(new HornetQTopic("deploy"), new MessageCreator() {
@Override
public Message createMessage(Session session) throws JMSException {
TextMessage txtMessage = session.createTextMessage("my message");
return txtMessage;
}
});
System.out.println("Stop live server");
System.in.read();
producer.send(new HornetQTopic("deploy"), new MessageCreator() {
@Override
public Message createMessage(Session session) throws JMSException {
TextMessage txtMessage = session.createTextMessage("my message");
return txtMessage;
}
});
Thread.sleep(60000);
}
输出：
Stop live server
Apr 30, 2012 5:08:32 PM org.hornetq.core.logging.impl.JULLogDelegate warn
WARNING: Tried 1 times to connect. Now giving up on reconnecting it.
另外，直播服务器有日志错误：
