案例代码：

import lombok.Data;

import java.lang.reflect.InvocationTargetException;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;

public class Demo {

    @Data
    public static class User {

        private Integer id;

        private String name;

        private String email;

        private String date;

    }

    public static void main(String[] args) {
        Map<String, Object> paramsMap = new HashMap<>();
        paramsMap.put("id", 123);
        paramsMap.put("name", "张三");
        paramsMap.put("email", "demo@163.com");
        paramsMap.put("date", new Date());
        User user = new User();
        try {
            org.Apache.commons.beanutils.BeanUtils.populate(user, paramsMap);
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        } catch (InvocationTargetException e) {
            e.printStackTrace();
        }
        System.out.println("user=>" + user);
    }

}

输出：

user=>Demo.User(id=123, name=张三, email=demo@163.com, date=Tue Aug 10 13:14:36 CST 2021)
