java - 无法将类型 [JmsManagedConnectionFactoryImpl] 的值转换为所需类型 [javax.jms.ConnectionFactory]

Question

我已经通过 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>

我的 web.xml:

<resource-ref>
    <description>JMS Connection</description>
    <res-ref-name>jms/ConnectionFactory</res-ref-name>
    <res-type>javax.jms.ConnectionFactory</res-type>
    <res-auth>Container</res-auth>
    <res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>

但是，当我尝试在我的 Websphere 中绑定(bind) JNDI 资源时，在启动我的应用程序时出现以下错误:

据我了解，IBM 的 JmsManagedConnectionFactoryImpl 应该实现 JmsTemplate，否则我什至没有机会通过 WebSphere 绑定(bind)它，那么这里可能是什么问题？

Answer 1

JmsTemplate 是 Spring 框架中的一个类。所以类 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，您正在将 JMS api 类打包到您的应用程序中。当您在 WebSphere 中部署应用程序时，WAS 在类路径中也有 API 类，并且您有冲突，因为在不同的类加载器中有两个 API jar。因此，只需从您的部署中排除 API jar，错误就会消失。
