Xstream（Java）不正確反序列化Xml字符串到對象

Question

我有以下XML字符串，我試圖將其反序列化到一個對象，但最終的結果是不正確的。

的XML字符串是：
<Header><Sequence value=\"bbb-mySeq\"/><Session value=\"aaa-myValue\"/></Header>";

，我試圖以反序列化對象是：

public class Header implements Serializable { 

private static final long serialVersionUID = 1L; 

private List<Session> sessions = new ArrayList<Session>(); 
private List<Sequence> sequences = new ArrayList<Sequence>(); 

public List<Session> getSession() { 
    return sessions; 
} 

public void setSession(Session session) { 
    this.sessions.add(session); 
} 

public List<Sequence> getSequence() { 
    return sequences; 
} 

public void setSequence(Sequence sequence) { 
    this.sequences.add(sequence); 
    } 

} 

序列對象是：

public class Sequence implements Serializable { 

private static final long serialVersionUID = 1L; 
private String value; 

public String getValue() { 
    return value; 
} 

public void setValue(String value) { 
    this.value = value; 
} 

} 

反序列化代碼是：

XStream xstream = new XStream(); 

    xstream.alias("Header", Header.class); 
    xstream.alias("Session", Session.class); 
    xstream.alias("Sequence", Sequence.class); 

    xstream.addImplicitCollection(Header.class, "sessions"); 
    xstream.addImplicitCollection(Header.class, "sequences"); 

    xstream.useAttributeFor(Session.class, "value"); 
    xstream.useAttributeFor(Sequence.class, "value"); 
    System.out.println("msg: " + msg); 

    Header result = (Header) xstream.fromXML(msg); 

當我得到的對象上做一個toString()，我看到：

Header [sessions=null, sequences=[Sequence [value=bbb-mySeq], Session [value=aaa-myValue]]] 

正如你所看到的，應該有序列沒有會話。預先感謝您的幫助。

您的通話切換到addImplicitCollection：

xstream.addImplicitCollection(Header.class, "sessions", Session.class); 
xstream.addImplicitCollection(Header.class, "sequences", Sequence.class);
