java - 使用 XStream 序列化为 XML 但未获取所有字段

Question

我有一个名为 Lookup 的类，它有两个属性:

public class Lookup {

    private String surveyName;
    private String GUID;    

    public Lookup(String name, String guid){
        this.surveyName = name;
        this.GUID = guid;   
    }

}

在另一个类(class)中，我有一个 Lookup 列表，我正在尝试将其序列化并保存到文件中。我就是这样做的:

List<Lookup> lookup = new ArrayList<Lookup>();
lookup.add(new Lookup("foo","bar"));
XStream serializer = new XStream();
serializer.alias("Lookups",List.class);
String xml = serializer.toXML(lookup);

我最终得到的 XML 是:

<Lookups>
  <Lookup>
    <GUID>bar</GUID>
  </Lookup>
</Lookups>

如您所见，它仅序列化了字段GUID，但没有序列化字段surveyName。为什么它忽略该字段？

您确定没有在其他地方修改 Lookup 变量吗？这段代码运行良好

public class Test {
    public static void main(String[] args) {
        List<Lookup> lookup = new ArrayList<Lookup>();
        lookup.add(new Lookup("foo","bar"));
        XStream serializer = new XStream();
        serializer.alias("Lookups",List.class);
        String xml = serializer.toXML(lookup);
        System.out.println(xml);
    }
}
class Lookup {
    private String surveyName;
    private String GUID;    

    public Lookup(String name, String guid){
        this.surveyName = name;
        this.GUID = guid;   
    }
}

输出:

<Lookups>
  <Lookup>
    <surveyName>foo</surveyName>
    <GUID>bar</GUID>
  </Lookup>
</Lookups>
