XStream - XML ​​zu ArrayList

Question

Ich bin ziemlich neu in Java. Ich habe eine XML-Datei, die ich mit xStream.toXML aus einer ArrayList erstellen konnte.

Meine Client-Klasse hat die folgenden Objekte:

• String: Name, ID

• Integer: Balance

• Arraylist: Telefon

• ArraList: bestDay

• Artikel (benutzerdefinierte Klasse): Daten

My Item-Klasse die folgenden Objekte hat:

• String: Name

• Integer: Preis

Die XML Datei sieht so aus:

<list> 
    <client> 
    <name>Client 1</name> 
    <id>054.658.547-74</id> 
    <phone> 
     <string>99564-5412</string> 
     <string>7854-5478</string> 
    </phone> 
    <bestDay> 
     <int>10</int> 
    </bestDay> 
    <balance>-20.0</balance> 
    <data> 
     <item> 
     <name>Item 1</name> 
     <price>5.0</price> 
     </item> 
     <item> 
     <name>Item 2</name> 
     <price>3.0</price> 
     </item> 
     <item reference="../item"/> 
     <item reference="../item[2]"/> 
    </data> 
    </client> 
    <client> 
    <name>Client 2</nome> 
    <id>047.654.987-78</id> 
    <phone> 
     <string>99564-1475</string> 
     <string>98544-5254</string> 
    </phone> 
    <bestDay> 
     <int>15</int> 
     <int>30</int> 
    </bestDay> 
    <balance>-15.0</balance> 
    <data> 
     <item> 
     <name>Item 3</name> 
     <price>4.0</price> 
     </item> 
     <item reference="../item"/> 
     <item reference="../item"/> 
     <item reference="../item"/> 
     <item reference="../item"/> 
    </data> 
    </client> 
</list> 

Nun, wenn ich versuche, wieder diesen Code in eine Arraylist zu machen, mit diesem Code:

XStream xStream = new XStream(); 
String rawXML = new String(Files.readAllBytes(Paths.get("output.xml"))); 
ArrayList<Client> = (ArrayList<Client>)xStream.fromXML(rawXML); 

Ich erhalte eine Fehlermeldung in der letzten Zeile.

EDIT:

Ok, ich hatte nur auf die buildpath hinzugefügt:

• xstream-1.4.10.jar

• xpp3_min-1.1.4c.jar

Jetzt habe ich xmlpull-1.1.3.1.jar hinzugefügt und ich habe eine andere Fehler:

Security framework of XStream not initialized, XStream is probably vulnerable.
