spring integration 的 tcp-inbound-channel-adapter 和 tcp-connection-factory 是否支持故障转移？

Question

我有一个使用 spring 集成的简单 tcp 客户端，它接收消息并将其写入文件。

我希望客户端默认连接到thing.input.primary.host，但是在连接失败的情况下，我希望它重新连接到thing.input.secondary.host，然后发送消息就像普通的; Spring 集成是否支持这种行为？

编辑：为清楚起见。如果thingClient失败，我想做的是让它从thingClient切换到thingClientSecondary。

没有；只需定义使用另一个工厂和相同通道的第二个通道适配器；那么来自任一端口的任何数据都将转到同一个地方。

“故障转移”在服务器端是一个不寻常的术语。通常，当服务器连接丢失时，客户端会进行故障转移。

在服务器端，我们是被动的，“故障转移”一词在这里没有意义。
