Question

当我在 Maven 内的嵌入式 jetty 中运行示例项目时，出现以下异常。

这是我在 persistence.xml 中的属性

<properties> 
         <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
        <!-- <property name="hibernate.hbm2ddl.auto" value="update" /> -->
        <property name="hibernate.hbm2ddl.auto" value="none" /> 
        <property name="hibernate.show_sql" value="false" />
        <property name="hibernate.format_sql" value="true" />


        <property name="hibernate.cache.region.factory_class" value="net.sf.ehcache.hibernate.SingletonEhCacheRegionFactory"/>
        <!-- Enable/Disable the second-level cache --> 
        <property name="hibernate.cache.use_second_level_cache" value="true"/> 

        <!-- cache implementation --> 
        <property name="hibernate.cache.provider_class" value="org.hibernate.cache.EhCacheProvider"/> 

        <!-- store the second-level cache entries in a more human-friendly format --> 
        <property name="hibernate.cache.use_structured_entries" value="true"/> 

        <!-- enable/disable the query cache --> 
        <property name="hibernate.cache.use_query_cache" value="true"/>

    </properties>

，我将所有依赖项包含在我的 pom.xml 中。有人可以提供一些缺少哪些属性的见解吗？

您可能想查看此问题的答案。检查您是否从 persistence.xml 而不是 Spring 上下文读取设置。
