Kotlin获得声明的成员财产价值 [英] Kotlin get declared member property value

问题描述

Class#getDeclaredField 在科特林吗?我正在寻找一个纯粹的Kotlin实现...也许是一种反思?

What is the equivalent code of Class#getDeclaredField in Kotlin? I'm looking for a pure Kotlin implementation... a reflection perhaps?

class Test {
    public static final String TEST = "Hello";
    public static void main(String[] args) {
        System.out.println(
            Test.class.getDeclaredField("TEST").get(Test.class));
    }
}

推荐答案

首先，添加此依赖项以避免运行时错误

first, add this dependency to avoid runtime error

<dependency>
    <groupId>org.jetbrains.kotlin</groupId>
    <artifactId>kotlin-reflect</artifactId>
    <version>1.3.50</version>
</dependency>

然后:

val member = Test::class.members.find { it.name=="TEST" }
println(member)
println(member.call(Test())

输出:

val generic.Test.TEST: kotlin.String
Hello

成员类型为可通话的< *>?
