java – 如何用jaxb包装子列表

目前的结果是：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> 
    <Customer>
       <id>100</id>
       <name>John Doe</name>
       <orders>
         <address>100 main street,smalltown,pa</address>
         <orderid>1100</orderid>
       </orders>
      <orders>
         <address>5 broadway,ny,ny</address>
         <orderid>1200</orderid>
       </orders> 
    </Customer>

但我想得到：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> 
    <Customer>
       <id>100</id>
       <name>John Doe</name>
       <orders>
         <order>
           <address>100 main street,pa</address>
           <orderid>1100</orderid>
         </order>
         <order>
            <address>5 broadway,ny</address>
            <orderid>1200</orderid>
         </order>
       </orders> 
    </Customer>

需要改变才能得到这个结果？

并使用这个jaxb实现：
