java - Byte Buddy - 如何使字段自类型？

Question

有必要描述一下这个类的结构

class A{
    private List<A> listA;   
}

尝试了解决方案:Byte-buddy: generate classes with cyclic types

但是会报错

java.lang.ExceptionInInitializerError Caused by:java.lang.IllegalStateException: Cannot resolve declared type of alatent type description:...

Answer 1

您可以使用TargetType 作为当前生成类型的引用:

new ByteBuddy()
  .subclass(Object.class)
  .name("A")
  .defineField("listA", 
      TypeDescription.Generic.Builder.parameterizedType(
          List.class, TargetType.class).build(),
      Visibility.PRIVATE)
  .make()
