磁盘存储的ehCache配置不起作用

【中文标题】磁盘存储的ehCache配置不起作用【英文标题】：ehCache configuration for disk storage not working 【发布时间】：2020-10-24 03:08:34 【问题描述】：

我无法让我的 ehCache 与 diskStorage 一起使用。我想要一个在我重新启动我的应用程序后存在的持久缓存。所以我尝试了 ehCache，这是我的 ehCache 配置文件：

<diskStore path="C:\Temp\ehCache"/>  
<cache 
    name="testCache"  
    eternal="true"
    maxElementsInMemory="0"
    overflowToDisk="true"
    diskPersistent="true"        
    >
</cache>

只要我不重新启动应用程序，缓存就会工作。在我重新启动应用程序并且 ehCache 尝试从缓存文件中加载数据后，我收到此错误：

我尝试了不同的配置变体，例如以编程方式配置或 xml 配置标签：

<persistence strategy="localRestartable" synchronousWrites="true"/>

但如果我不使用上面发布的配置，我总是会收到错误：

无法配置缓存 testCache，因为找不到企业功能管理器。您必须使用企业版 Ehcache 才能成功启用企业持久性。

有人知道这个问题吗？

库：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-cache</artifactId>
    <version>2.2.2.RELEASE</version>
  </dependency>
  <dependency>
    <groupId>net.sf.ehcache</groupId>
    <artifactId>ehcache</artifactId>
    <version>2.10.6</version>
  </dependency>

我还有一个 ShutdownListener 来关闭 CacheManager

 public class SpringEhcacheShutdownListenerBean implements ApplicationListener 
    @Override
    public void onApplicationEvent(ApplicationEvent event) 
        if (event instanceof ContextClosedEvent) 
            CacheManager.getInstance().shutdown();

这是我的服务方式

@Cacheable(cacheNames = "testCache", key = " #root.methodName, #collectiveNr " )
public org.wc3.Document getVCXml(String collectiveNr, Session session) throws ServiceException  ...

【问题讨论】：

我认为你使用了错误的库，请显示完整的 pom 文件和 spring boot jpa 依赖项我不明白你想把什么放入缓存。请分享您提到的课程的代码 【参考方案1】：

好的，我暂时解决了。原来是 org.w3c.dom.Document 类导致了这个问题。它需要大量内存才能从磁盘反序列化。所以当我增加线程堆栈大小（-xss2m）时它起作用了。

【参考方案2】：

我没有使用 jpa。我只是想缓存一些服务类。
