使用Spring配置集群Hornetq客户端

Question

我正在尝试使用hornetq核心API和将是HA的spring来定义hornetq客户端。 但是，当我停止实时服务器，而备份服务器变为“实时”时，客户端将失败，并显示连接错误。 知道我在做什么错吗？

我定义了群集的独立hornetq服务器（没有组或发现）。 hornetq-configuration.xml文件：

...
<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);
}

OUTPUT：

 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，实时服务器出现日志错误：

Answer 1

我找到了如何创建与HA一起使用的hornetq客户端的方法，但它要求我使用JNDI并通过查找获得连接工厂。 我确实是这样的：

<bean id="jndiTemplate" class="org.springframework.jndi.JndiTemplate">
    <property name="environment">
        <props>
            <prop key="java.naming.provider.url">jnp://jndi-host:jndi-port</prop>
            <prop key="java.naming.factory.initial">org.jnp.interfaces.NamingContextFactory</prop>
        </props>
    </property>
</bean>

<bean id="connectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiTemplate" ref="jndiTemplate" />
    <property name="jndiName" value="ConnectionFactory" />
</bean>

没有JNDI，有没有办法创建这样的客户端？

spring config设置HornetQ故障转移到备份服务器

<bean id="hornetQConnectionFactory" class="org.hornetq.jms.client.HornetQJMSConnectionFactory">
        <constructor-arg index="0" name="ha" value="true" />
        <constructor-arg index="1">
            <list>
                <bean class="org.hornetq.api.core.TransportConfiguration">
                    <constructor-arg value="org.hornetq.core.remoting.impl.netty.NettyConnectorFactory" />
                    <constructor-arg>
                        <map key-type="java.lang.String" 
                             value-type="java.lang.Object">
                            <entry key="host" value="Q-server-1"></entry>
                            <entry key="port" value="5445"></entry>
                        </map>
                    </constructor-arg>
                </bean>
                <bean class="org.hornetq.api.core.TransportConfiguration">
                    <constructor-arg value="org.hornetq.core.remoting.impl.netty.NettyConnectorFactory" />
                    <constructor-arg>
                        <map key-type="java.lang.String" 
                             value-type="java.lang.Object">
                            <entry key="host" value="Q-server2"></entry>
                            <entry key="port" value="5446"></entry>
                        </map>
                    </constructor-arg>
                </bean>
            </list>
        </constructor-arg>
    </bean>

Q1是主要的，而Q2是备用的。 适用于HornetQ hornetq-2.4.0.Final独立安装，以及hornetq-jms-client版本的客户端：2.4.5.Final
