无法将[JmsManagedConnectionFactoryImpl]类型的值转换为所需的[javax.jms.ConnectionFactory]类型

我通过JNDI设置了一个JMSTemplate，如下所示：

<bean id="jmsTopicCancelacionTemplate" class="org.springframework.jms.core.JmsTemplate">
        <property name="connectionFactory" ref="connectionFactory" />
        <property name="defaultDestination" ref="cancelacionTopic" />
        <property name="messageConverter" ref="oxmMessageConverter" />
        <property name="destinationResolver" ref="jmsDestResolver" />
        <property name="pubSubDomain" value="true" />
    </bean>

 <!-- look up the JMS ConnectionFactory in JNDI -->
    <bean id="connectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean">
        <property name="jndiName">
            <value>java:comp/env/jms/ConnectionFactory</value>
        </property>
    </bean>

<bean id="requestQueue" class="org.springframework.jndi.JndiObjectFactoryBean">
        <property name="jndiName">
            <value>java:comp/env/jms/SchedulingRequestQueue</value>
        </property>
    </bean>

据我所知，IBM的JmsManagedConnectionFactoryImpl应该实现JmsTemplate，否则我甚至没有机会通过WebSphere绑定它，那么这里会有什么问题呢？

JmsTemplate是Spring框架中的一个类。因此，类JmsManagedConnectionFactoryImpl与JmsTemplate无关（JmsTemplate使用ConnectionFactory，但不是相反的方式）。但是，我认为您的问题是，您正在应用程序中打包JMS api类。当您在WebSphere中部署应用程序时，WAS在类路径中也有API类，您会遇到冲突，因为在不同的类加载器中有两个API JAR。因此，只要从部署中排除API JAR，错误就会消失。

我知道它们是不同的；我的意思是，JmsTemplate需要一个javax.jms.ConnectionFactory，这就是我提供给它的。当你谈论api时，你的意思是我应该排除包含javax.jms.ConnectionFactory的JAR，让WAS使用他的？难道不应该通过将我的项目配置为父类（我已经有了）来避免这种情况吗？不，因为然后WebSphere使用他的类来初始化JMS连接（因为您在WebSphere中配置了它），然后Spring尝试将WebSphere中的连接对象与应用程序特定的类一起使用，这是相同的代码，但是不同类加载器的不同类对象（您刚刚加入了类加载器地狱）。您好，感谢这个线程，它非常有用。但是，在从WEB-INF/lib中删除所有ActiveMQ依赖项并将WS-class loader设置为父类last和single class loader之后，我仍然存在这个问题。我是否应该从部署中排除任何其他API？谢谢。如果还有一个JAR，里面有ConnectionFactory类，您能在IDE中进行搜索吗？Eclipse和IntelliJ应该显示，如果您打开某个JAR，它将保存一个特定的类。
