通过JNDI查找Websphere ConnectionFactory时出现ClassCastException

时间：2018-03-16 06:59:22

标签： java spring-boot jms websphere

我收到以下类强制转换异常。 可能是因为我的应用程序使用JMS 2.0 API，而Websphere 8.5.x正在返回JMS v1.x兼容对象

是Websphere 8.5.x限制吗？我可以在Websphere和/或应用程序上更改什么，以便它返回/使用javax.jms.ConnectionFactory对象？

Caused by: java.lang.ClassCastException: com.ibm.ejs.jms.JMSConnectionFactoryHandle incompatible with javax.jms.ConnectionFactory
    at com.mypackage.myclass.MyConfig.getConnectionFactory(MyConfig.java:152)

Websphere建议使用我已经使用的javax.jms.ConnectionFactory对象，但仍然会遇到上述异常。

http://www-01.ibm.com/support/docview.wss?uid=swg21238470

代码： 

conFactory = (ConnectionFactory) jndiLookup(jndiConnetionFctoryPath);

Stacktrace是：

WebSphere 8.5仅支持JMS 1.x.最有可能发生的事情是您正在对JMS对象进行JNDI查找，该JMS对象由位于JMS 1.x的应用程序服务器管理。您的应用程序可能配置了JMS 2.0类，并从应用程序和查找中优先加载到JMS 1.x版本，因此您无法进行转换。到兼容的类型。如果您需要JMS 2.0，那么您应该使用WebSphere 9。
