java - JBoss EAP 7 和 Ifinispan

Question

我有一个用 JEE 编写的 Web 应用程序。我使用 hibernate 作为 JPA 提供程序，并且我想使用 Infinispan 作为二级缓存。当我浏览互联网时，我注意到只需要添加几行。我在 persistence.xml 中添加了这些行

<property name="hibernate.cache.provider_class" value="org.hibernate.cache.infinispan.InfinispanRegionFactory"/>
<property name="javax.persistence.sharedCache.mode" value="ENABLE_SELECTIVE"/>
<property name="hibernate.cache.use_second_level_cache" value="true"/>
<property name="hibernate.cache.region.factory_class" value="org.hibernate.cache.infinispan.InfinispanRegionFactory"/>
<property name="hibernate.cache.use_query_cache" value="true"/>

但是在 JBoss 上部署ear和war文件期间我收到一条错误消息

更新
当我的持久单元看起来像这样

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0"

          ...
        </properties>

    </persistence-unit>

</persistence>  

我遇到异常

Caused by: org.hibernate.cache.NoCacheRegionFactoryAvailableException: Second-level cache is used in the application, but property hibernate.cache.region.factory_class is not given; please either disable second level cache or set correct region factory using the hibernate.cache.region.factory_class setting and make sure the second level cache provider (hibernate-infinispan, e.g.) is available on the classpath.

将以下行添加到 persistence.xml 后

<property name="hibernate.cache.region.factory_class" value="org.hibernate.cache.infinispan.InfinispanRegionFactory" />

我仍然遇到 JMX MBean 异常

也许我需要某种 infinispan 配置文件，我可以在其中放置

<jmx duplicate-domains="true" />

就像这里提到的那样Infinispan as second level cache hibernate

Answer 1

您应该检查 EAP 7 文档，因为获得二级缓存(由 Infinispan 在幕后提供支持)所需的所有配置如下:

<persistence-unit name="...">
  (...) <!-- other configuration -->
  <shared-cache-mode>ENABLE_SELECTIVE</shared-cache-mode>
  <properties>
    <property name="hibernate.cache.use_second_level_cache" value="true" />
    <property name="hibernate.cache.use_query_cache" value="true" />
  </properties>
</persistence-unit>
