警告：发生了非法反射访问操作 Apache Ignite

Question

我使用 apache ignite: Ignite ignite = Ignition.start() 但它返回一个错误：

WARNING: An illegal reflective access operation has occurred

为什么我会收到此错误以及如何修复它。 我有 JDK 14 我尝试添加：运行方式 -> 运行配置 -> Arguments -> VM ->

--add-exports=java.base/jdk.internal.misc=ALL-UNNAMED
--add-exports=java.base/sun.nio.ch=ALL-UNNAMED

但错误并没有消失

您需要将具有依赖关系的ignite-spring模块添加到您的类路径以读取 XML 配置。 引用的警告与此无关。
