java - BeanUtils copyProperties 复制Arraylist

Question

我知道 BeanUtils 可以将单个对象复制到其他对象。

是否可以复制数组列表。

例如:

 FromBean fromBean = new FromBean("fromBean", "fromBeanAProp", "fromBeanBProp");
 ToBean toBean = new ToBean("toBean", "toBeanBProp", "toBeanCProp");
 BeanUtils.copyProperties(toBean, fromBean);

如何实现？

List<FromBean > fromBeanList = new ArrayList<FromBean >();  
List<ToBean > toBeanList = new ArrayList<ToBean >();  
BeanUtils.copyProperties(toBeanList , fromBeanList );

它不适合我。谁能帮帮我。

提前致谢。

如果您有一个包含数据的列表源和空的列表目标，解决方案是:

    List<Object> listOrigin (with data)
    List<Object> listDestination= new ArrayList<Object>(); 

     for (Object source: listOrigin ) {
        Object target= new Object();
        BeanUtils.copyProperties(source , target);
        listDestination.add(target);
     }
