Apache PropertyUtils是如何进行属性拷贝的

首先要添加Apache PropertyUtils的Jar包，即添加依赖

<dependency>
<groupId>commons-beanutils</groupId>
<artifactId>commons-beanutils</artifactId>
<version>1.9.4</version>
</dependency>
<dependency>
<groupId>commons-logging</groupId>
<artifactId>commons-logging</artifactId>
<version>1.1.2</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

PersonDTO personDTO = new PersonDTO();
PropertyUtils.copyProperties(personDTO, personDO);
