非法反射 警告 好像也不影响什么

WARNING: An illegal reflective access operation has occurred
    WARNING: Illegal reflective access by org.xnio.nio.NioXnio$2 (file:/Users/jixianzhilu/.m2/repository/org/jboss/xnio/xnio-nio/3.3.8.Final/xnio-nio-3.3.8.Final.jar) to constructor sun.nio.ch.KQueueSelectorProvider()
    WARNING: Please consider reporting this to the maintainers of org.xnio.nio.NioXnio$2
    WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
    WARNING: All illegal access operations will be denied in a future release

忽略这个警告 适用于jdk11

import java.lang.reflect.Field;
    	import java.lang.reflect.Method;
    	/**
    	 * 忽略非法反射警告  适用于jdk11
    	 */
        @SuppressWarnings("unchecked")
        public static void disableAccessWarnings() {
            try {
                Class unsafeClass = Class.forName("sun.misc.Unsafe");
                Field field = unsafeClass.getDeclaredField("theUnsafe");
                field.setAccessible(true);
                Object unsafe = field.get(null);
    
                Method putObjectVolatile = unsafeClass.getDeclaredMethod("putObjectVolatile", Object.class, long.class, Object.class);
                Method staticFieldOffset = unsafeClass.getDeclaredMethod("staticFieldOffset", Field.class);
    
                Class loggerClass = Class.forName("jdk.internal.module.IllegalAccessLogger");
                Field loggerField = loggerClass.getDeclaredField("logger");
                Long offset = (Long) staticFieldOffset.invoke(unsafe, loggerField);
                putObjectVolatile.invoke(unsafe, loggerClass, offset, null);
            } catch (Exception ignored) {
            }
        }

例如 在springboot中启用

public static void main(String[] args) {
    		disableAccessWarnings();
    		SpringApplication.run(Application_Launcher.class, args);
    		
    	}
