如何在 Websphere 8 上为 Springs WorkManagerTaskExecutor 获取 JCA Workmanager

Question

我们使用 Websphere 8 Application Server，我想在我们的 Web 应用程序中使用服务器工作管理器。我正在尝试获取对 jca workmanager javax.resource.spi.work.Workmanager 的引用以将其与 Springs org.springframework.jca.work.WorkManagerTaskExecutor.

一起使用

web.xml 中的资源参考如下所示：

<resource-ref>
 <res-ref-name>workmanager/web</res-ref-name>
 <res-type>javax.resource.spi.work.WorkManager</res-type>
 <res-auth>Container</res-auth>
 <res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>

使用该配置，我得到以下异常：

Caused by: com.ibm.ws.asynchbeans.exception.AsynchBeanException: ASYN0064E: The value javax.resource.spi.work.WorkManager of the res-type resource reference element WorkManager is not right. Only the following values are allowed: com.ibm.websphere.asynchbeans.WorkManager, commonj.work.WorkManager.

这里说我的资源引用必须是 com.ibm.websphere.asynchbeans.WorkManager 或 commonj.work.WorkManager 类型。它们都不是从 JCA-Workmanager-Interface 扩展的。

如果我将资源类型切换为 commonj.work.WorkManager 并在我的应用程序中使用 Springs org.springframework.scheduling.commonj.WorkManagerTaskExecutor，一切正常。

要让 JCA Workmanager 与 Websphere 一起工作，我是否需要在服务器端配置一些特殊的东西？我还没有在管理控制台中找到任何设置来切换实现。 Websphere 8 支持Java EE 6，所以应该可以处理JCA。

为什么要使用特定于 JCA 的 WorkManagerTaskExecutor 而不是常见的 WorkManagerTaskExecutor？ JCA WorkManager仅供资源适配器使用，不被任意EE组件引用，JCA-specific WorkManagerTaskExecutor的Spring documentation与此一致：

This is mainly intended for use within a JCA ResourceAdapter implementation

只需使用commonj WorkManager 和相应的WorkManagerTaskExecutor。
