将POJO内容从一个bean复制到另一个bean [英] Copy POJO content from one bean to another

问题描述

我在不同的包中有很少的Pojos，每个POJO包含来自同一个包的另一个pojo的集合。我需要将包裹B Pojos中具有相同名称的所有项目复制到包A中的对象。

I have few Pojos in different packages, each POJO contains set of the another pojo from the same package. I need to copy all items with the same name from Package B Pojos to objects in Package A.

Eaxmple：

package com.vanilla.packageA;

public class Student{

    private String firstName;
    private String lastName;
    private Set<Course> course;

    //getters and setters ommited

}   

< hr>

---

package com.vanilla.packageA;

    public class Course{
    private String courseName;
    private String courseDescription;

    //seters and getters
}

---

---

package com.vanilla.packageB;

public class Student{

    private String firstName;
    private String lastName;
    private Address address;
    private Set<Course> course;
    Private Date birtday;

    //getters and setters ommited

}   

< hr>

---

package com.vanilla.packageB;

public class Course{
    private String courseName;
    private String courseDescription;
    private <Lecturer> lecturer;
    private Integer hours;

    //seters and getters
} 

我想要将 PackageB 类中的所有项目递归地复制到 packageA 存在于 PaCkageB 并且共享相同的名称。

I want to copy recursively all items from PackageB classes to packageA classes which exists in PaCkageB and shares the same name.

更新：

伙计们，我明白这是愚蠢的问题，但我需要维护这段代码，现在代码的编写方式是他们必须调用50个getter和setter，或者用50个参数调用构造函数。
不幸的是，我不能使用相同的对象，我需要复制它，但我必须找到更多优雅的方式来复制tese bean。

Guys, I understand that that this is stupid question, but I need to maintain this code, now the code is written in the way that they have to call 50 getters and setter, or calling constructor with 50 parameters. Unfortunately, I can't use the same object and I need to copy it, but I must find more "elegant" way to copy tese beans.

推荐答案

Apache BeanUtils.copyProperties 不起作用？

Any reason why Apache BeanUtils.copyProperties does not work?
