java - 使用 xstream 填充列表值

Question

我正在使用Xstream以下格式读取一些 xml

 <Objects>  
  <Object Type="System.Management.Automation.Internal.Host.InternalHost">   
    <Property Name="Name" Type="System.String">ConsoleHost</Property>   
    <Property Name="Version" Type="System.Version">2.0</Property>   
    <Property Name="InstanceId" Type="System.Guid">7e2156</Property>
  </Object> 
</Objects> 

基本上在对象标签下可以有 n 个对象类型，每个对象类型可以有 n 个属性标签。所以我用Java类和代码来建模如下

 @XStreamAlias("Objects")
class ParentResponseObject {
    @XStreamImplicit
    List <ResponseObject>responseObjects = new ArrayList<ResponseObject>(); 
    public String toString () {
        return responseObjects.get(0).toString();       
    }   
}
@XStreamAlias("Object")
@XStreamConverter(value = ToAttributedValueConverter.class, strings = { "value" })
class ResponseObject {
    @XStreamAsAttribute
       String Type;
       String value;
       @XStreamImplicit
       List <Properties> properties = new ArrayList<Properties>();  
      public String toString () {
        return Type+" value is "+"List is "+properties+ value;      
    }   
}
@XStreamAlias("Property")
@XStreamConverter(value = ToAttributedValueConverter.class, strings = { "value" })
class Properties {
    @XStreamAsAttribute
    String Name;
    @XStreamAsAttribute
    String Type;
    String value;
    Properties (String name, String type,String value) {
            this.Name = name;
            this.Type = type;
            this.value =  value;
        }   
}

使用此代码，我可以responseObjects在类中填充列表ParentResponseObject。但是，即使我在这两种情况下都使用相同的技术，列表中的属性ResponseObject总是并且不会被填充。null我调试了很多，但找不到任何东西。征求您的帮助和指导。

添加对隐式的引用它将起作用

  @XStreamImplicit(itemFieldName="Object")
  List<ResponseObject> responseObjects = new ArrayList<ResponseObject>();

  @XStreamImplicit(itemFieldName="Property")
  List<Properties> properties = new ArrayList<Properties>();
