使用BeanUtils在bean之间复制具有不同名称的属性 [英] Copy property with different names between beans using BeanUtils

问题描述

我想使用具有相同字段但名称不同的BeanUtils将属性值从A类复制到B类.是否可以提供一个属性名称映射到differentName，年龄映射到differentAge等，并实现复制?我很想知道是否可以仅通过Apache Commons实用程序(而不是任何其他工具)以任何方式实现.

I would like to copy the property values from Class A to Class B with BeanUtils which has same fields but with different names. Is it possible to provide a map of property name to differentName, age to differentAge etc., and achieve the copying? I am interested to know if this is possible by any means using only Apache Commons utilities (not any other tools).

class ClassA{
    private String name;
    private Integer age;
    ... // Setter and Getter methods
} 

class ClassB{
    private String differentName;
    private Integer differentAge;
    ... // Setter and Getter methods for the private fields
}

推荐答案

Apache Commons BeanUtils具有方法

Apache Commons BeanUtils has method the method populate(Object bean, Map properties) accepts a map to populate the Bean with key value pairs.

注意:我刚刚看到了Apache-Commons的局限性-但它可能对其他人还是有用的，就我而言，更好的解决方案.

NOTE: I just saw the limitation on Apache-Commons - but it may still be useful for other people and as far as I am concerned the better solution.

在名称匹配时使用推土机，它将自动复制值.或者根据您的情况，您可以在xml映射文件中指定源成员和目标成员.

Use Dozer when the names match it will automatically copy the values. Or as in your case you can specify source and target Members in an xml mapping file.
