警告：Apache Ignite发生了非法的反射访问操作

Question

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

为什么会出现此错误，以及如何解决该错误。我有JDK 14我尝试添加：运行方式->运行配置->参数-> VM->

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

但是错误不会消失

您需要将具有依赖性的ignite-spring模块添加到类路径中以读取XML配置。被引警告与此无关。
