Hibernate 5应用迁移时无法创建CacheImplementor服务的问题求助

大家好，我最近在把项目迁移到Hibernate 5版本时，启动阶段碰上个棘手的问题——SessionFactory创建失败了，具体的报错信息如下：

ERROR repository.legacy.HibernateSessionManager - "Initial SessionFactory creation failed"
org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.cache.spi.CacheImplementor]
    at org.hibernate.service.internal.AbstractServiceRegistryImpl.createService(AbstractServiceRegistryImpl.java:275)
Caused by: net.sf.ehcache.CacheException: java.io.IOException: Access is denied
    at net.sf.ehcache.DiskStorePathManager$DiskStorePath.<init>(DiskStorePathManager.java:331)
Caused by: java.io.IOException: Access is denied
    at java.io.WinNTFileSystem.createFileExclusively(Native Method)

目前我用的Hibernate核心依赖是：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>5.6.1.Final</version>
</dependency>

搭配的EHCache依赖如下（内容没粘贴完整）：

<dependency>
    <groupId>org.ehcache</groupId>
    ...
</dependency>

有没有朋友遇到过类似的问题呀？麻烦帮忙分析下可能的原因和解决办法，谢谢大家了！
