JBoss EAP 7和Ifinispan

标签： java hibernate jboss infinispan jboss-eap-7

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，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"/>

但在JBoss上部署ear和war文件时，我收到一条错误消息

更新
当我的持久性单元看起来像这样

<?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"
             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence

          ...
        </properties>

    </persistence-unit>

</persistence>

我收到了异常

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 

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

我仍然使用JMX MBean

获得异常

也许我需要某种infinispan配置文件，我可以放置

<jmx duplicate-domains="true" />
像这里提到的那样Infinispan as second level cache hibernate

2 个答案:

答案 0 :(得分：1)

您应该查看EAP 7文档，因为获得二级缓存所需的所有配置（由Infinispan在后台提供支持）是：

<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>

答案 1 :(得分：0)

hibernate版本应为5.0.x。

persistence.xml：

<persistence ...>
        <persistence-unit ...>
                ...
                <shared-cache-mode>ENABLE_SELECTIVE</shared-cache-mode>  <!-- ADD THIS -->
                <properties>
                        ...
                        <property name="hibernate.cache.use_second_level_cache" value="true" />  <!-- KEEP THIS -->
                </properties>
        </persistence-unit>
</persistence>

删除所有其他hibernate.cache。*属性----只留下上面的

请注意，使用上述设置必须将实体明确标记为@Cacheable。如果不希望将每个实体明确标记为@cacheable，则可以使用ALL设置进行共享缓存模式，然后缓存所有实体。

有关配置和实施的其他文档，请参阅 EAP 7：Hibernate 5用户指南（http://docs.jboss.org/hibernate/orm/5.0/userguide/html_single/Hibernate_User_Guide.html#caching）和Hibernate 5开发人员指南（http://docs.jboss.org/hibernate/orm/5.0/devguide/en-US/html_single/#d5e1433）和Infinispan 8用户指南（http://infinispan.org/docs/8.1.x/user_guide/user_guide.html）
