启动时出现 Gemfire PDX 错误：PDX 元数据已创建为对等元数据区域。请先创建您的池
Gemfire PDX error on startup : The PDX metadata has already been created as a peer metadata region. Please create your pools first
我是 gemfire 的新手，使用它启动我的应用程序时遇到问题。
我得到的错误是

您可以尝试在 Spring 中配置 Client.xml 中的内容。
知道了。
问题是 applicationContext.xml 上的区域名称有一个拼写错误（小写字母）所以该区域没有被创建，之后我试图将它添加到池中。
无论如何，那个错误信息太可怕了……也许与它缺失的区域相关的东西会有很大帮助。
希望对其他人有所帮助。
同意，错误消息可能不是那么有用，但这是 GemFire 特定的异常（即 PdxInitializationException）和错误消息。
