将pojo字段复制到另一个pojo的二传手 [英] Copy pojo fields to another pojo's setters

问题描述

假设我有带有公共字段x和y的类A.假设我还有另一个pojo类B，但是它使用了setter和getter，所以它有setX()和setY().

Let's say I have class A with public fields x and y. And let's say I have another pojo class B but that uses setters and getters, so it has setX() and setY().

我想使用某种自动方式从A实例复制到B并返回.

I'd like to use some automatic way to copy from instance of A to B and back.

至少使用默认设置，推土机

With default settings at least, Dozer's

   Mapper mapper = new DozerBeanMapper();
   B b = mapper.map(a, B.class);

不能正确复制字段.

那么是否有一个简单的配置更改可以使我使用Dozer或其他可以为我完成此任务的库来完成上述工作?

So is there a simple configuration change that allows me to accomplish the above with Dozer, or another library that would do this for me?

推荐答案

我建议您使用:

或者看看这个问题:

从字段中复制所有值在一个班级中通过反思到另一个班级

我想说API(BeanUtils)和ModelMapper都提供了将pojos的值复制到另一个pojos的一线式.看看@这个:

I'd say that both API's (BeanUtils) and ModelMapper provide one-liners for copy pojos' values to another pojos. Take a look @ this:
