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 workmanager。我正在尝试获取对 jca workmanager 的引用以javax.resource.spi.work.Workmanager将其与 Springs 一起使用org.springframework.jca.work.WorkManagerTaskExecutor

web.xml 中的资源引用如下所示:

<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.

它在这里说我的资源引用必须是类型com.ibm.websphere.asynchbeans.WorkManageror commonj.work.WorkManager。它们都不是从 JCA-Workmanager-Interface 扩展而来的。

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 commonj?JCA WorkManager 仅供资源适配器使用,不被任意 EE 组件引用,JCA 特定 WorkManagerTaskExecutor 的Spring 文档与此一致:

这主要用于在 JCA ResourceAdapter 实现中使用

只需使用 commonj WorkManager 和对应的 WorkManagerTaskExecutor。
