java - 如何在 Dozer 中映射集合

Question

我想做这样的事情:

ArrayList<CustomObject> objects = new ArrayList<CustomObject>();
...
DozerBeanMapper MAPPER = new DozerBeanMapper();
...
ArrayList<NewObject> newObjects = MAPPER.map(objects, ...); 

假设:

<mapping>
  <class-a>com.me.CustomObject</class-a>
  <class-b>com.me.NewObject</class-b>   
    <field>  
      <a>id</a>  
      <b>id2</b>  
    </field>  
</mapping>

我试过了:

ArrayList<NewObject> holder = new ArrayList<NewObject>();
MAPPER.map(objects, holder);

但是持有者对象是空的。我还尝试更改第二个参数，但没有任何运气......

"Nested collections are handled automatically, but you are correct that top level collections need to be iterated over. Currently there isn't a more elegant way to handle this."

Someone has figured a way to do it without a looping construct in your code base ，但我认为将它放入您的代码中更容易(并且更具可读性/可维护性)。希望他们能尽快添加此功能。
