创建2个实体类如下:

package com.example.demo.entity;

/**
 * hlvy
 *
 * @author heng
 **/
public class hlvy {
    /**
     * 姓名
     */
    private String name;

    /**
     * 年龄
     */
    private Integer age;


    public String getName() {
        return name;
    }

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

    public Integer getAge() {
        return age;
    }

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

package com.example.demo.entity;

/**
 * hlvy
 *
 * @author heng
 **/
public class hlvy2 {
    /**
     * 姓名
     */
    private String name;

    /**
     * 年龄
     */
    private Integer age;


    public String getName() {
        return name;
    }

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

    public Integer getAge() {
        return age;
    }

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

    @Override
    public String toString() {
        return "hlvy2{" +
                "name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
}

使用方法

 hlvy hlvy = new hlvy();
        hlvy2 hlvy2 = new hlvy2();
        hlvy.setName("heng");
        hlvy.setAge(18);
        BeanUtils.copyProperties(hlvy,hlvy2);//参数1是要被copy的对象  参数二是要被赋值的对象
        System.out.println(hlvy2.toString());//输出hlvy2{name='heng', age=18}
