無法將類型的值JmsManagedConnectionFactoryImpl]所需類型[javax.jms.ConnectionFactory] ​​

Question

我已經通過JNDI設置中，JmsTemplate這樣的：

<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，當我嘗試綁定我的Websphere中的JNDI資源時，啓動我的應用程序時出現以下錯誤：

我的理解是，IBM的JmsManagedConnectionFactoryImpl應該實現JmsTemplate，否則我甚至沒有機會通過WebSphere進行綁定，那麼這裏可能會出現什麼問題？

Answer 1

JmsTemplate是Spring框架中的一個類。所以類JmsManagedConnectionFactoryImpl與JmsTemplate無關（JmsTemplate使用ConnectionFactory，但不是顛倒的方式）。不過，我認爲你的問題是，你在應用程序中打包JMS api類。在WebSphere中部署應用程序時，WAS在類路徑中也有API類，並且存在衝突，因爲在不同的類加載器中有兩個API JAR。所以只需從您的部署中排除API jar，並且錯誤應該消失。
