Apache Ignite配置错误

我们已经构建了一个4节点的ApacheIgnite集群，能够连接并执行基本操作，比如从Java程序创建缓存

但在我进行MySQL集成时，它无法连接到Ignite集群

以下是错误消息

以下是Ignite配置文件：

错误已通过以下更改得到解决：


在ignite Libs目录中添加了最新的MySQL JDBC jar
确保集群配置文件和客户机配置文件相同（早期的客户机配置文件在缓存配置中很少包含其他配置）
添加了Person类（这是一个MySQL表POJO，将存储在Ignite缓存中）
能否与我们分享PersonExample.PersonStore类代码？
