下面是我试图看看它是否能解决此异常的情况

  • 将client-cache.xml文件配置从缓存\u PROXY\u HEAP\u LRU更改为缓存\u PROXY甚至PROXY。它不起作用，异常仍然存在
  • 还尝试在client-cache.xml文件中添加以下内容，但效果不佳。我在所有地区都这么做了
    • 从异常中可以看出，服务器正在尝试反序列化
    models.article.Author的实例，但在类路径中找不到类定义
    
您使用的是哪一个？是否尝试将包含类模型的jar添加到服务器的类路径
    

    干杯。
    类models.article.Author是已部署工件的一部分。它不是从外部jar文件引用的。此外，还需要注意的是，当我使用相同的工件连接到Gemfire 6实例时，它工作得很好。Re：数据序列化机制，我不知道是否有我正在使用的任何特定数据序列化机制。所有类都是java可序列化接口的子类型，因此我假设gemfire正在扩展相同的序列化策略。我还没有在client-cache.xml文件中定义任何序列化/反序列化策略。因此，可能会使用默认的序列化策略。我会参考你提供的链接。有人能帮忙调查一下吗？
