Question

如果您查看此页面： http://www.eclipse.org/eclipselink/documentation/2.4/jpa/extensions/a_cache.htm

它表示以下内容：

（可选）将此属性设置为高速缓存协调模式（org.eclipse.persistence.annotations.CacheCoordinationType枚举类型）。您还必须在持久性单元属性中配置缓存协调。请参阅“缓存”。

由于引用的文档未提供示例，因此我无法确定要设置的属性。我试过了，但是有一个例外：

<property name="eclipselink.cache.type.coordinationType" value="INVALIDATE_CHANGED_OBJECTS" />

有人知道该怎么做吗？谢谢！

我想为其他任何人添加答案：

我们添加了以下PU属性，并且缓存效果很好！我们在Apache TomEE上运行，因此如果您在其他应用服务器上，则下面的openejb:Resource/jms/connectionFactory值将有所不同

        <property
            name="eclipselink.cache.coordination.protocol"
            value="jms" />
        <property
            name="eclipselink.cache.coordination.jms.topic"
            value="openejb:Resource/com.xxx.applications.eclipselink.cache" />
        <property
            name="eclipselink.cache.coordination.jms.factory"
            value="openejb:Resource/jms/connectionFactory" />
        <property
            name="eclipselink.cache.coordination.jms.reuse-topic-publisher"
            value="true" />
        <property
            name="eclipselink.cache.coordination.remove-connection-on-error"
            value="true" />
        <property
            name="eclipselink.session.name"
            value="com.xxx.xxx-jpa-model" />

如何在persistence.xml中设置默认的Eclipselink CacheCoordinateType？
