一、Ignite代码部署属性配置
除了对等类加载之外，还可以通过配置UriDeploymentSpi部署用户代码。使用这种方法，可以在节点配置中指定库文件的位置。Ignite会定期扫描该位置，并在类文件有变更时重新部署。该位置可以是文件系统目录或HTTP(S)位置。当Ignite检测到库文件已从该位置删除时，这些类将从集群中卸载。可以通过提供目录和http(s)的URL来指定（不同类型的）多个位置。
要从文件系统目录部署库文件，需要将目录路径添加到UriDeploymentSpi配置中的URI列表中。该目录必须存在于指定目录的节点上，并且包含要部署的类的jar文件。注意，必须使用file：//模式指定路径。可以在不同的节点上指定不同的目录。
