我們正在編寫Java 8 + Play 2應用程序。Gemfire 8.1 - 異常 - ServerOperationException - SerializationException - 一個ClassNotFoundException
我們是在從遷移6的GemFire到的GemFire 8
下面是我的GemFire客戶cache.xml文件的過程。

有了這個配置，我有一些gemfire相關的工作，除了我在日誌中收到下面的異常。

現在下面是我想看看它是否工作來解決這個例外
- 改變了客戶cache.xml文件配置從CACHING_PROXY_HEAP_LRU到CACHING_PROXY甚至PROXY的事情。它不起作用，異常仍然存在
- 也嘗試在client-cache.xml文件中添加下面的東西，但它沒有奏效。我爲所有地區做過。
<region name="five_minute_ttl" refid="CACHING_PROXY_HEAP_LRU">
<region-attributes pool-name="gemfire_qa_instance">
<eviction-attributes>
<lru-heap-percentage action="local-destroy" />
</eviction-attributes>
</region-attributes>
</region>除了這個之外，一切似乎是工作的罰款與客戶的GemFire 6.6.2連接到服務器的GemFire 8.1.0
我已將gemfire客戶端從6.6.2更新到8.1.0，並對client-cache.xml文件進行了更改，以使XML符合gemfire 8.1.0客戶端。以下是Gemfire 8.1.0客戶端的client-cache.xml文件。但錯誤仍然存在。

任何人都可以幫忙看看這個嗎？ – user3616964
