Class LookupFactory

java.lang.Object

cn.hutool.core.lang.reflect.LookupFactory

public class LookupFactory
extends Object

MethodHandles.Lookup工厂，用于创建MethodHandles.Lookup对象
jdk8中如果直接调用MethodHandles.lookup()获取到的MethodHandles.Lookup在调用findSpecial和unreflectSpecial 时会出现权限不够问题，抛出"no private access for invokespecial"异常，因此针对JDK8及JDK9+分别封装lookup方法。 参考：
