如何通过反射找出字段是否为类型的instanceof? [英] How to find out if a field is instanceof a type via reflection?

问题描述

我想通过反射找出某个字段是否是某种 T 类型的实例.

I want to find out via reflection if a field is an instance of some type T.

假设我有一个对象 o .现在，我想知道它是否具有 T 实例的任何字段.我可以通过以下方式获取所有字段:

Lets say I have an object o. Now I want to know if it has any fields which are instance of T. I can get all fields with:

o.getClass().getFields();

我可以通过以下方式获取字段类型:

I can get the type of the field with:

field.getType();

但是现在我想知道此类型或任何超类型是否等于 T .我是否必须递归调用 getSuperclass()以确保检查所有超类型?

But now I want to know if this type or any supertype equals T. Do I have to call getSuperclass() recursively to be sure to check all supertypes?
