Java中如何使泛型函数根据输入获取对象属性

import java.lang.reflect.Field;

public class GenericFunction<T> {
    private T obj;

    public GenericFunction(T obj) {
        this.obj = obj;
    }

    public Object getProperty(String propertyName) throws NoSuchFieldException, IllegalAccessException {
        Class<?> clazz = obj.getClass();
        Field field = clazz.getDeclaredField(propertyName);
        field.setAccessible(true);
        return field.get(obj);
    }

    public static void main(String[] args) throws NoSuchFieldException, IllegalAccessException {
        // 创建一个示例对象
        MyClass myObj = new MyClass();
        myObj.setName("John");
        myObj.setAge(25);

        // 创建一个泛型函数对象
        GenericFunction<MyClass> genericFunction = new GenericFunction<>(myObj);

        // 获取对象属性并打印
        String name = (String) genericFunction.getProperty("name");
        int age = (int) genericFunction.getProperty("age");
        System.out.println("Name: " + name);
        System.out.println("Age: " + age);
    }
}

class MyClass {
    private String name;
    private int age;

    // 省略构造函数和其他方法

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
}
