我启动服务器，没有错误消息。我启动了我的客户端并挂起说：

[17:31:35]无法从IP查找程序连接到任何地址（将重试每2000毫秒加入拓扑;更改'reconnectDelay'进行配置重试次数）：[localhost / 127.0.0.1:8080]

悲伤。

它似乎适用于多播，但这对我们来说不是一个选择。在此示例中，服务器和客户端都在同一节点上运行。

Answer 1

DiscoverySpi和CommunicationSpi是用于不同目的的不同组件，它们使用不同的TCP连接。因此，如果您要使用8080进行发现，则应在localPort上设置DiscoverySpi属性，同时为CommunicationSpi执行此操作。

Apache Ignite静态IP将无法连接
