Apache Ignite 使用 Spring-Boot 加载两次？
Posted
技术标签:
【中文标题】Apache Ignite 使用 Spring-Boot 加载两次？【英文标题】：Apache Ignite Loading Twice with Spring-Boot? 【发布时间】：2016-02-01 21:00:54 【问题描述】：我正在使用 Spring-Boot 1.2.7.RELEASE 和 Apache Ignite 1.4.0 进行原型设计，发现有些奇怪，可能只是一个日志配置。
看起来 Apache Ignite 尝试使用 Spring 启动两次？如果我注释掉 SpringApplication.run 行，那么它看起来只启动一次。也许我没有正确使用 Spring 和 Apache Ignite？

【问题讨论】：
【参考方案1】：这不是“两个实例”，而是 Ignite 记录启动横幅的两种方式 - 一种使用 STDOUT，另一种使用内置记录器。
只需添加 ignite-slf4j 依赖并使用 IgniteConfiguration 的 setGridLogger 方法覆盖默认记录器 - 此消息将消失。
【讨论】：
【参考方案2】：实际上，Ignite 在两种情况下都会启动一次（带有注释和未注释的 SpringApplication.run 行）。每个 Ignite 节点都会打印出当前的拓扑快照，但我在日志中只看到一行：
Topology snapshot [ver=14, servers=2, clients=0, CPUs=8, heap=3.7GB]
