Java反射，通过对象获取属性及属性值

package com.test.test;

import java.lang.reflect.Field;

public class Test {
    public static void main(String[] args) throws IllegalAccessException {
        Person p1 = new Person("张三", "高中生");
        getObj(p1);
    }

    public static void getObj(Object obj) throws IllegalAccessException {
        Field[] fields = obj.getClass().getDeclaredFields();
        for (Field field : fields) {
            if (!field.isAccessible()) {
                field.setAccessible(true);
            }
            System.out.println(field.getName() + ":" + field.get(obj));
        }
    }
}

class Person {

    private String name;
    private String desc;

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

    public String getName() {
        return name;
    }

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

    public String getDesc() {
        return desc;
    }

    public Person setDesc(String desc) {
        this.desc = desc;
        return this;
    }
}

输出结果

name:张三
desc:高中生
