在設置hibernate分佈式ehcache與兵馬俑的會話工廠問題

我想在兵馬俑的分佈式環境中設置EHCache。在這裏，我可以連接應用程序服務器和Terracotta服務器，並在兵馬俑開發人員控制檯中查看複製對象。在設置hibernate分佈式ehcache與兵馬俑的會話工廠問題

但在應用服務器continiously以下異常消息出現，但應用程序的其餘部分運行正常：

大家好，如果任何機構可以指導爲什麼會出現這個異常信息，以及我們如何解決這個問題。此外，它將有助於我有任何全面的教程來設置hibernate應用程序的兵馬俑。

這裏[CacheByAmitNode8081]是我在應用程序服務器中定義的緩存節點的名稱。

當你使用兵馬俑時，你需要在你的類路徑中添加特定的兵馬俑瓶子來代替ehcache實現。在您的異常堆棧我沒有看到任何兵馬俑類輸出...

在我的Maven依賴我：

<dependency> 
    <groupId>net.sf.ehcache</groupId> 
    <artifactId>ehcache-core-ee</artifactId> 
    <version>2.5.2</version> 
    <scope>compile</scope> 
</dependency> 
<dependency> 
    <groupId>net.sf.ehcache</groupId> 
    <artifactId>ehcache-terracotta-ee</artifactId> 
    <version>2.5.2</version> 
    <scope>compile</scope> 
</dependency> 
<dependency> 
    <groupId>org.terracotta</groupId> 
    <artifactId>terracotta-toolkit-1.5-runtime-ee</artifactId> 
    <version>4.2.0</version> 
    <scope>compile</scope> 
</dependency>
