问题：

磁盘存储的ehCache配置不工作

彭宏深
2023-03-14

我无法让我的ehCache与磁盘存储一起工作。我想要一个持久缓存存在后，我重新启动我的应用程序。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试图从缓存文件加载数据之后，我得到了这个错误：

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 { ...}

好的，我暂时解决了。原来是org.w3c.dom.Document类引起了这个问题。从磁盘反序列化需要大量内存。因此，当我增加线程堆栈大小(-xss2m)时，它起作用了。

  • ehcache磁盘存储异常关闭

    问题内容： 我正在使用具有磁盘存储持久性的缓存。在随后重新运行该应用程序时，出现以下错误： 除了在应用程序中的某个位置显式调用之外，还有什么方法可以解决此问题？ 缓存配置： 复制问题的代码： 问题答案： 尝试设置系统属性： net.sf.ehcache.enableShutdownHook = true 因此，您可以在程序的开头添加以下行： 或者，从命令行传递属性： 注意，ehcache网站在使用

  • 使用磁盘存储缓存时的 EHcache 性能

    我们在应用程序中使用ehcache。请看以下配置： 既然我们已经配置为eternal="true "，那么它会永远创建缓存吗？。磁盘空间有可能用完吗？ 对磁盘存储的性能会有什么影响？。肯定比内存缓存慢，但是影响有多大。 如果磁盘中存储了更多缓存，是否会导致执行多个文件操作的IO问题？ 请建议生产级应用的最佳实践。假设我们有一个3 GB的堆内存和25000个并发用户访问应用程序。但是，我们的应用程序

  • ehcache不会从磁盘存储中过期元素

    我只想将元素缓存在diskstore中，而不是内存/ram中，为此我使用了以下配置，它将元素存储在磁盘上，但不会在5分钟后过期/从磁盘删除数据。 我可以在ehcache配置中做什么，该配置将在指定时间后使diskstore中的元素过期？

  • 将 EhCache 磁盘存储内容加载到内存中

    如EhCache留档所述： 实际上，这意味着持久性内存中缓存将启动，其所有元素都将在磁盘上。[...]因此，Ehcache设计不会在启动时将它们全部加载到内存中，而是根据需要懒惰地加载它们。 我希望内存缓存启动时将所有元素都存储在内存中，我该如何实现？ 这是因为我们的网站对缓存执行了大量的访问，所以我们第一次访问网站时，它的响应时间非常长。

  • ehcache持续存在磁盘问题

    问题内容： 我想用Java中的ehcache做一些我认为应该非常简单的事情，但是我花了很多时间使自己的文档感到沮丧… 将值写入磁盘持久性缓存。关掉。 重新启动并读取该值。 这是我的Java函数： 这是我的缓存配置（ehcache.xml）： 即使我在第一次运行后在磁盘上看到test.index和test.data文件，此函数的输出始终是以下内容（它似乎从未从磁盘加载缓存）： 找不到缓存。正在创建缓

  • 使用Heroku临时文件系统作为Ehcache磁盘存储

    正如 Heroku Dyno 临时文件系统文档所解释的那样，当 dyno 停止或重新启动时，文件系统将被丢弃。这意味着它不能用作永久（磁盘）存储。 我的用例是我想使用Ehcache缓存一些参考数据。我在考虑使用一些（有限的）堆内存以获得最佳性能，如果它不足以回退到磁盘存储。使用Ehcache，这可以在每个缓存的基础上进行很好的配置，例如在堆内存中存储最多1000个条目，例如在磁盘上存储25MB。
