配置缓存提供程序persistence.xml以及其他一些相关属性，如下所示。

<shared-cache-mode>ALL</shared-cache-mode>

<properties>
    <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/>
    <property name="hibernate.show_sql" value="true" />
    <property name="hibernate.format_sql" value="true" />
    <property name="hibernate.event.merge.entity_copy_observer" value="allow"/>
    <property name="hibernate.use_sql_comments" value="true" />

    <property name="hibernate.cache.region.factory_class" value="org.hibernate.cache.ehcache.EhCacheRegionFactory"/>
    <property name="hibernate.cache.use_second_level_cache" value="true"/>
    <property name="hibernate.cache.use_query_cache" value="true"/>
    <property name="hibernate.cache.use_structured_entries" value="true"/>
    <property name="hibernate.cache.generate_statistics" value="true"/>
    <property name="hibernate.cache.infinispan.statistics" value="true" />
    <property name="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.ImprovedNamingStrategy"/>
</properties>

当以下两个 JAR 文件添加到 EE 模块本身的编译时类路径时，此方法有效。

  • hibernate-ehcache-5.0.6.Final.jar
  • ehcache-core-2.4.3.jar

是否允许将这些 JAR 文件作为模块添加到服务器本身，因为这些 JAR 文件不需要存在于编译时类路径中？

当尝试在${Home}/modules/system/layers/base/net/sf/ehcache/main/module.xml.

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.3" name="net.sf.ehcache">
    <resources>
        <resource-root path="hibernate-ehcache-5.0.6.Final.jar"/>
        <resource-root path="ehcache-core-2.4.3.jar"/>
    </resources>

    <dependencies>
        <module name="org.hibernate"/>
        <module name="org.slf4j"/>
    </dependencies>
</module>

它会导致抛出以下异常，就好像它根本没有效果一样。

是否不允许将这两个 JAR 文件作为模块添加到服务器，或者存在不同的方法来实现这一点？

该模块org.hibernate包含以下资源及其依赖项。

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.3" name="org.hibernate">
    <resources>
        <resource-root path="hibernate-core-5.0.6.Final.jar"/>
        <resource-root path="hibernate-envers-5.0.6.Final.jar"/>
        <resource-root path="hibernate-entitymanager-5.0.6.Final.jar"/>
    </resources>

    <dependencies>
        <module name="asm.asm"/>

    </dependencies>
</module>

我在 WildFly 9.0.2 final 中使用 Hibernate 5.0.6 final。

我认为您必须执行以下步骤：

  1. 在主休眠模块中添加 hibernate-ehcache.jar；

  2. 像 wildfly 模块一样添加 ehcache。您必须使用 ehcache jar 和 module.xml 创建一个文件夹：[wildfly]/modules/system/layers/base/net/sf/ehcache/main。

  3. 在主 hibernate module.xml 中引用 ehcache 模块。

在 Wildfly（例如版本 10）中，您可以使用 Infinispan（与 JSR107 兼容）来代替进行 L2 缓存。在 wildfly 的模块目录 - org/hibernate/main/module.xml，你必须像这样使用（无需指定“hibernate-ehcache-5.0.11.Final.jar”）：

 <resource-root path="hibernate-core-5.0.11.Final.jar"/>
 <resource-root path="hibernate-envers-5.0.11.Final.jar"/>
 <resource-root path="hibernate-entitymanager-5.0.11.Final.jar"/>
 <resource-root path="hibernate-java8-5.0.11.Final.jar"/>

WildFly 服务器默认加载 Infinispan。

在您的 persistence.xml 中，配置将是：

 <!-- enable query cache -->
  <property name="hibernate.cache.use_query_cache" value="true"/>
  <!-- EhCache provider-->
  <!-- <property name="hibernate.cache.region.factory_class" value="org.hibernate.cache.ehcache.EhCacheRegionFactory"/> -->
  <!-- 2nd level cache -->
  <property name="hibernate.cache.use_second_level_cache" value="true"/>
  <!-- enable statistics -->
  <property name="hibernate.generate_statistics" value="false"/>
  <!-- for Wildfly only -->
  <property name="wildfly.jpa.hibernate.search.module" value="org.hibernate.search.orm:5.5.5.Final"/>
