使用SystemClock.now()替换。
2.isAssignableFrom();
使用新定义的isAssignableFromForCC()方法替换

return ClassUtils.isAssignable(cls, tocls);// use org.apache.commons.lang3.ClassUtils;
}
3.obj.hashCode()
使用新定义的hashCodeForCC()方法替换
public static int hashCodeForCC(Object obj) {
return ObjectUtils.hashCode(obj);//org.apache.commons.lang3.ObjectUtils;
}
4.getModifiers()
使用新定义的getModifiersForCC()方法替换
public static int getModifiersForCC(Class clazz) {
return ReflectUtils.getClassInfo(clazz).getModifiers();//org.springframework.cglib.core.ReflectUtils;
}
5.Thread.sleep(1000L);
TimeUnit.SECONDS.sleep(1);
