Question

我正在尝试评估HornetQ以及将其嵌入spring应用程序中的可能性。从简单的设置开始，我只是尝试按如下方式初始化它。除了'你可以'之外，我没有找到关于如何做到这一点的文档。

我正在使用Spring 3和HornetQ 2.1.1GA

我的Spring配置看起来像这样，但如果有一个更简单的清洁配置，它会更好。我首先想要简约的方法，然后在它上面构建。：

    <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">


<bean name="mbeanServer" class="java.lang.management.ManagementFactory" factory-method="getPlatformMBeanServer" />

<bean name="fileConfiguration" class="org.hornetq.core.config.impl.FileConfiguration" init-method="start" destroy-method="stop" />

<bean name="hornetQSecurityManagerImpl" class="org.hornetq.spi.core.security.HornetQSecurityManagerImpl" />

<!-- The core server -->
<bean name="hornetQServerImpl" class="org.hornetq.core.server.impl.HornetQServerImpl">
 <constructor-arg ref="fileConfiguration" />
 <constructor-arg ref="mbeanServer" />
 <constructor-arg ref="hornetQSecurityManagerImpl" />
</bean>

<!-- The JMS server -->
<bean name="jmsServerManagerImpl" class="org.hornetq.jms.server.impl.JMSServerManagerImpl" init-method="start" destroy-method="stop" >
 <constructor-arg ref="hornetQServerImpl" />
</bean>

    <bean name="connectionFactory" class="org.hornetq.jms.client.HornetQConnectionFactory" >
 <constructor-arg>
  <bean class="org.hornetq.api.core.TransportConfiguration">
   <constructor-arg value="org.hornetq.integration.transports.netty.NettyConnectorFactory" />
   <constructor-arg>
    <map key-type="java.lang.String" value-type="java.lang.Object">
     <entry key="port" value="5445"></entry>
    </map>
   </constructor-arg>
  </bean>
 </constructor-arg>
</bean>

<bean name="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
 <property name="connectionFactory" ref="connectionFactory"></property>
</bean>

</beans>

使用此配置我收到错误：

它必须是与JNDI明显相关的东西，但我会欣赏适当的简约配置，然后再展开它。 HornetQ配置文件是分发附带的默认配置文件（默认队列，默认用户等）

您需要定义要添加到服务器的JMS队列，并为每个队列指定一个空的JNDI绑定列表。为此，请将JMSConfigurationImpl添加到JMSServerManagerImpl bean定义中。例如，如果您需要定义名为“testqueue”的队列：

  <bean id="hornetQJmsConfig" class="org.hornetq.jms.server.config.impl.JMSConfigurationImpl">
    <constructor-arg index="0">
      <list/>
    </constructor-arg>
    <!-- Queue configurations -->
    <constructor-arg index="1">
      <list>
        <bean class="org.hornetq.jms.server.config.impl.JMSQueueConfigurationImpl">
          <!-- Name -->
          <constructor-arg index="0" value="testqueue"/>
          <!-- Selector -->
          <constructor-arg index="1"><null/></constructor-arg>
          <!-- Durable queue -->
          <constructor-arg index="2" value="true"/>
          <!-- JNDI bindings, empty list for none -->
          <constructor-arg index="3"><list/></constructor-arg>
        </bean>
      </list>
    </constructor-arg>
    <!-- Topic configurations -->
    <constructor-arg index="2">
      <list/>
    </constructor-arg>
  </bean>

由于第二个和第三个构造函数args采用队列和主题配置列表，因此您可以根据需要添加任意数量的队列和主题。对于一两个以上，最好创建一个Spring模板对象。

在春天嵌入HornetQ
