替换sun.reflect.reflectionfactory newConstructorForserialization
有一个项目使用newConstructorForSerialization（class＆lt;？＆gt; incomingargument，object.class.getDeclaredConstructor（））来获取后来在使用> code>> > foreach field field.set（instance，fieldObj）;。
该API在新的Java版本中被弃用，编译器在构建过程中产生许多警告，因此我想用最新的东西替换它。如果我正确理解此代码，它将返回IncomingArgument的公共可用构造函数，该构建器仅初始化object superClass字段，对吗？
因此，它解决了三个任务：
- 从
mcOnstructor.newinstance（）中获取适量的内存; - 避免不必要的字段初始化（将稍后设置）；
- 使构造函数公开可用（可以是私人的，也可以不介绍）。
有没有办法在不使用弃用的API-S的情况下实现相同的方法？
谢谢。
there is a project that uses newConstructorForSerialization(Class<?> incomingArgument, Object.class.getDeclaredConstructor()) to get a constructor that is later used to create objects before they are actually initialized with foreach field field.set(instance, fieldObj);.
This api is deprecated in the new java releases and compiler produces many warnings during build so I would like to replace it with something up-to-date. If I understand this code correctly it returns a public available constructor for incomingArgument that only initializes Object superclass fields, am I right?
So it solves three tasks:
- get the right amount of memory from
mConstructor.newInstance(); - avoids unnecessary field initialization (they will be set later);
- makes the constructor publicly available (it could be private or not be presented).
Is there a way to achieve the same without using deprecated api-s?
Thanks.

I was able to solve the issue by using
sun.misc.Unsafe.allocateInstancevia google protobuf proxy (https://github.com/protocolbuffers/protobuf/blob/520c601c99012101c816b6ccc89e8d6fc28fdbb8/java/core/src/ main/java/com/google/protobuf/unsafeutil.java＃l98 ），所以现在该依赖关系是单独编译的，因此我看不到警告，我可以期望Google将其修复，如果sun。 Misc.unsafe由于Java更新而停止工作。I was able to solve the issue by using
