解决springboot警告WARNING: All illegal access operations will be denied in a future release

一、问题描述 WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by org.springframework.cglib.core.ReflectUtils (file:/C:/Users/.m2/repository/org/springframework/spring-core/5.2.8.RELEASE/spring-core-5.2.8.RELEASE.jar) to method java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int,java.security.ProtectionDomain) WARNING: Please consider reporting this to the maintainers of org.springframework.cglib.core.ReflectUtils 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 二、解决方法

网上给出不少版本，

1、降低jdk版本，如使用的是Java11，改成Java8

2、在启动类增加以下方法，启动springboot的时候调用一下这个方法，亲测试 jdk 11 有效

public static void disableWarning() { try { Field theUnsafe = Unsafe.class.getDeclaredField("theUnsafe"); theUnsafe.setAccessible(true); Unsafe u = (Unsafe) theUnsafe.get(null); Class cls = Class.forName("jdk.internal.module.IllegalAccessLogger"); Field logger = cls.getDeclaredField("logger"); u.putObjectVolatile(cls, u.staticFieldOffset(logger), null); } catch (Exception e) { // ignore } } public static void main(String[] args) { disableWarning(); SpringApplication.run(CpmApiApplication.class, args); }
