【问题描述】：
我对 Java 还是很陌生。我有一个 XML 文件，我设法使用 xStream.toXML 从 ArrayList 创建了该文件。
我的客户端类有以下对象：
字符串：名称、id
整数：余额
ArrayList：电话
ArraList: bestDay
项目（自定义类）：数据
我的 Item 类有以下对象：
字符串：名称
整数：价格
XML 文件如下所示：
<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>
现在，当我尝试再次将此代码变为 ArrayList 时，使用此代码：
XStream xStream = new XStream();
String rawXML = new String(Files.readAllBytes(Paths.get("output.xml")));
ArrayList<Client> = (ArrayList<Client>)xStream.fromXML(rawXML);
最后一行出现错误。
编辑：
好的，我只添加了构建路径：
xstream-1.4.10.jar
xpp3_min-1.1.4c.jar
现在我添加了 xmlpull-1.1.3.1.jar 并且出现了另一个错误：
Security framework of XStream not initialized, XStream is probably vulnerable.
