Spring BeanUtils是如何进行属性拷贝的

首先要添加Spring BeanUtils 的Jar包，即添加依赖

<!--Spring PropertyUtils-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>org.springframework.beans</artifactId>
<version>3.1.1.RELEASE</version>
</dependency>

构建两个类对象进行属性赋值

public class PersonDO {
private Integer id;
private String name;
private Integer age;
private Date birthday;
// 省略setter/getter
}

public class PersonDTO {
private String name;
private Integer age;
private Date birthday;
}

进行属性赋值 org.springframework.beans.BeanUtils.copyProperties(personDO, personDTO);
