Jaxb 将xml解组到对象列表

我的rest jersey服务返回一个客户列表，在本例中只有一个

<customers>
 <customer>
  <age>24</age>
  <id>163</id>
  <name>Lory</name>
  <surname>Vinci</surname>
  <docNumber>123</docNumber>
  <fiscalCode>12345bg</fiscalCode>
 </customer>
</customers>

课程如下： 用户有4个属性：姓名、姓氏、id、年龄 客户通过docNumber和fiscalCode两个属性扩展用户。 我还得到了由

Customer customer = (Customer) unmarshaller.unmarshal(reader);

它是：

有什么想法吗？

您可以创建一个

Customers

类，该类包含

客户

对象的

列表，并将其添加到您的模型中

@XmlRootElement
@XmlAccessorType（XmlAccessType.FIELD）
公共类客户{
@xmlement（name=“客户”）
私人名单客户；
}
