Question

在将现有特定于webhere的项目迁移到tomcat时，我收到错误could not instantiate RegionFactory [org.hibernate.cache.ehcache.EhCacheRegionFactory]。我已将WebSphereUowTransactionManager更改为org.springframework.transaction.jta.JtaTransactionManager，因为它支持tomcat。但仍面临区域工厂的另一个问题

我正在将我的应用程序从webshpere迁移到tomcat，并且在使用web WAR文件运行tomcat服务器时出现以下错误。请帮我解决这个问题。我不确定从webshere迁移到tomcat时我必须使用哪个hibernate属性。我目前在持久性xml文件中使用下面的属性

    <property name="hibernate.cache.region.factory_class" value="org.hibernate.cache.ehcache.EhCacheRegionFactory"/>

我在hibernate jar文件下面使用

        ehcache-core-2.6.6
        hibernate-core-3.6.10.Final
        hibernate-jpa-2.0-api-1.0.1.Final

错误：

根本原因是java.lang.ClassNotFoundException:org.hibernate.cache.ehcache.EhCacheRegionFactory。

所以看起来你错过了类路径中的hibernate-ehcache.jar。

如果您使用maven作为依赖关系管理工具，请将以下依赖项添加到您的项目中：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-ehcache</artifactId>
    <version>3.6.10.Final</version>
</dependency>
