如何在Java中从字符串访问对象属性？

import java.lang.reflect.Field;

public class Main {
    public static void main(String[] args) throws NoSuchFieldException, IllegalAccessException {
        // 创建一个对象
        Person person = new Person("John", 25);

        // 获取对象的Class对象
        Class<?> clazz = person.getClass();

        // 定义要访问的属性名
        String fieldName = "name";

        // 获取属性对象
        Field field = clazz.getDeclaredField(fieldName);

        // 设置属性可访问
        field.setAccessible(true);

        // 获取属性值
        Object value = field.get(person);

        // 打印属性值
        System.out.println(value);
    }
}

class Person {
    private String name;
    private int age;

    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }
}
