通过反射设置附加属性的值

import java.lang.reflect.Field;

public class ReflectExample {
    private String name;
    private int age;

    public static void main(String[] args) throws NoSuchFieldException, IllegalAccessException {
        ReflectExample example = new ReflectExample();
        example.setName("John");
        example.setAge(25);

        // 使用反射设置附加属性的值
        Class<?> clazz = example.getClass();
        Field additionalField = clazz.getDeclaredField("additionalProperty");
        additionalField.setAccessible(true);
        additionalField.set(example, "Additional Value");

        System.out.println(example.getName());  // 输出：John
        System.out.println(example.getAge());   // 输出：25
        System.out.println(example.getAdditionalProperty());  // 输出：Additional Value
    }

    // 省略getter和setter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;
    }

    public String getAdditionalProperty() {
        return additionalProperty;
    }

    public void setAdditionalProperty(String additionalProperty) {
        this.additionalProperty = additionalProperty;
    }
}
