Active MQ，JNDI，彈出錯誤

Question

我是JNDI和JMS技術的入門者。

我有我的JNDI文件：

java.naming.factory.initial = org.apache.activemq.jndi.ActiveMQInitialContextFactory 

# use the following property to configure the default connector 
java.naming.provider.url = nio://localhost:61616 

# use the following property to specify the JNDI name the connection factory 
# should appear as. 
#jms.connectionFactoryNames = ConnectionFactory, queueConnectionFactory, topicConnectionFactry 
connectionFactoryName = queueConnectionFactory 
#connectionfactory.amqConnectionFactory = nio://localhost:61616 

# register some queues in JNDI using the form 
# queue.[jndiName] = [physicalName] 
queue.requestQueue = dq-dataloader.requestqueue 


# register some topics in JNDI using the form 
# topic.[jndiName] = [physicalName] 
#topic.MyTopic = example.MyTopic 

我的Spring配置文件是：

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

    <!-- <context:component-scan base-package="com.qpid.sample" /> --> 

    <bean id="jndiProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean"> 
     <property name="location" value="classpath:dq_dataloader-amq.properties" /> 
    </bean> 

    <!-- JNDI template --> 
    <bean id="jndiTemplate" class="org.springframework.jndi.JndiTemplate"> 
     <property name="environment" ref="jndiProperties" /> 
    </bean> 


    <!-- local ActiveMQ connection factory from JNDI context available via jndiTemplate --> 
    <bean id="amqConnectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean"> 
     <property name="jndiTemplate" ref="jndiTemplate" /> 
     <property name="jndiName" value="connectionFactoryName" /> 
    </bean> 

    <!-- caching connection factory --> 
    <bean id="connectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory"> 
     <property name="targetConnectionFactory" ref="amqConnectionFactory" /> 

     <!-- set the session cache size --> 
     <property name="sessionCacheSize" value="10" /> 
    </bean> 

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

</beans> 

祈求類：

import org.apache.commons.logging.Log; 
import org.apache.commons.logging.LogFactory; 
import org.springframework.context.ApplicationContext; 
import org.springframework.context.support.ClassPathXmlApplicationContext; 
import org.springframework.jndi.JndiTemplate; 

public class JMSSender { 

    private static Log logger = LogFactory.getLog(JMSSender.class); 
    JndiTemplate jndiTemplate; 

    public void init() { 
     ApplicationContext context = new ClassPathXmlApplicationContext("dq-dataloader-amq-beans.xml"); 
     jndiTemplate = (JndiTemplate) context.getBean("jndiTemplate"); 
     logger.info(""+jndiTemplate.getEnvironment().getProperty("java.naming.provider.url")); 

    } 

    public static void main(String [] argv) { 
     JMSSender sender = new JMSSender(); 
     sender.init(); 
    } 
} 

但是，當我試圖初始化它們我收到此錯誤：

任何幫助，將不勝感激。

問候。

Answer 1

由於您嘗試使用錯誤的JNDI名稱獲取對象，因此無法在JNDI中找到amqConnectionFactory。您可能想從dq_dataloader-amq.properties中獲取connectionFactoryName屬性值，而不是密鑰。使用${}從屬性文件中獲取值。

<bean id="amqConnectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean"> 
    <property name="jndiTemplate" ref="jndiTemplate" /> 
    <property name="jndiName" value="${connectionFactoryName}" /> 
</bean> 

Answer 2

在我看來，你有一個關於連接工廠名稱的簡單案例問題。

它應是一個上情況下，Q是這樣的：

connectionFactoryName = QueueConnectionFactory 

代替 「的QueueConnectionFactory」。
