Object 转为map

您可以使用Java中的BeanUtils工具类将Java对象转换为Map类型。下面是示例代码：

import org.apache.commons.beanutils.BeanUtils;

// Java对象
public class Person {
    private String name;
    private int age;

    // 省略getter和setter方法
}

// 将Java对象转换为Map
public static Map<String, String> objectToMap(Object obj) throws Exception {
    if (obj == null) {
        return null;
    }

    Map<String, String> map = new HashMap<String, String>();
    BeanUtils.populate(map, obj);

    return map;
}

// 测试代码
public static void main(String[] args) throws Exception {
    Person person = new Person();
    person.setName("Tom");
    person.setAge(20);

    Map<String, String> map = objectToMap(person);
    System.out.println(map); // 输出: {age=20, name=Tom}
}
