我正在尝试评估 HornetQ 以及将其嵌入到 Spring 应用程序中的可能性。从一个简单的设置开始,我只是尝试按如下方式初始化它。除了“你可以”这一事实之外,我没有找到太多关于如何做到这一点的文档。
我使用的是 Spring 3 和 HornetQ 2.1.1GA
我的 Spring 配置看起来像这样,但是如果有更简单的清洁配置会更好。我首先想要简约的方法,然后在此基础上进行构建。:
<?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="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,我收到错误消息:

它必须与 JNDI 明显相关,但我会很欣赏适当的简约配置,然后再扩展它。 HornetQ 配置文件是发行版附带的默认文件(默认队列、默认用户等)
最佳答案
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(bind)列表。为此,请将 JMSConfigurationImpl 添加到您的 JMSServerManagerImpl bean 定义中。例如,如果您需要定义一个名为“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 接受队列和主题配置列表,因此您可以添加任意数量的队列和主题。对于不止一两个,最好创建一个 Spring 模板对象。
