<? xml version="1.0" encoding="UTF-8"  ?>  
![None.gif][] < person >  
![None.gif][]     < name >yunyun </ name >  
![None.gif][]     < gender >true </ gender >  
![None.gif][]     < address >shanghai </ address >  
![None.gif][]     < contents >cc </ contents >  
![None.gif][]     < contents >ss </ contents >  
![None.gif][]     < taxs >  
![None.gif][]         < string >1 </ string >  
![None.gif][]         < string >2 </ string >  
![None.gif][]         < string >3 </ string >  
![None.gif][]     </ taxs >  
![None.gif][] </ person >

JavaBean

![ExpandedBlockStart.gif][] public  class Person2  \{  
![InBlock.gif][]     private String name;  
![InBlock.gif][]     private  boolean gender;  
![InBlock.gif][]     private String homeAddress;  
![InBlock.gif][]     private List<String> contentslist;  
![InBlock.gif][]     private String\[\] taxs;  
![InBlock.gif][]  
![InBlock.gif][]    @Override  
![ExpandedSubBlockStart.gif][]     public String toString() \{  
![InBlock.gif][]         return ToStringBuilder.reflectionToString( this);  
![ExpandedSubBlockEnd.gif][]    \}  
![InBlock.gif][]  
![ExpandedBlockEnd.gif][]\}

测试类 解析xml 反序列化到javaBean object

![ExpandedBlockStart.gif][] public  class TestXmlToObject2  \{  
![InBlock.gif][]  
![InBlock.gif][]      public  static  final XStream xstream= new XStream();  
![InBlock.gif][]       
![ExpandedSubBlockStart.gif][]      static\{  
![InBlock.gif][]         xstream.alias("person", Person2. class); // 类别名   
![InBlock.gif][]         xstream.aliasField("address", Person2. class, "homeAddress");  // 属性别名   
![InBlock.gif][]         xstream.alias("contents",String. class); // private List<String> contentslist;是string类型   
![InBlock.gif][]         xstream.addImplicitCollection(Person2. class, "contentslist"); // 隐式集合 隐藏contentslist   
![InBlock.gif][]         Person2 person=(Person2)xstream.fromXML(TestXmlToObject2. class.getClassLoader().getResourceAsStream("person02.xml"));  
![InBlock.gif][]         System.out.println(person.toString());  
![ExpandedSubBlockEnd.gif][]     \}  
![InBlock.gif][]      
![ExpandedSubBlockStart.gif][]     public  static  void main(String\[\] args) \{  
![InBlock.gif][]  
![ExpandedSubBlockEnd.gif][]    \}  
![InBlock.gif][]  
![ExpandedBlockEnd.gif][]\}

二： 注解方式  
xml：

![None.gif][] <? xml version="1.0" encoding="UTF-8"  ?>  
![None.gif][] < person >  
![None.gif][]     < name >yunyun </ name >  
![None.gif][]     < gender >true </ gender >  
![None.gif][]     < address >shanghai </ address >  
![None.gif][]     < company >yihaodian </ company >  
![None.gif][]     < sources >  
![None.gif][]         < string >firstSources </ string >  
![None.gif][]         < string >secondSources </ string >  
![None.gif][]     </ sources >  
![None.gif][]     < part >firstPart </ part >  
![None.gif][]     < part >secondPart </ part >  
![None.gif][] </ person >

javaBean

![None.gif][]@XStreamAlias("person")  
![None.gif][]public class Person3 \{  
![None.gif][]    private String name;  
![None.gif][]    private boolean gender;  
![None.gif][]    @XStreamAlias("address")  
![None.gif][]    private String homeAddress;  
![None.gif][]    private String company;  
![None.gif][]    @XStreamImplicit(itemFieldName="part")  
![None.gif][]    private List < String > content;  
![None.gif][]    private String\[\] sources;  
![None.gif][]      
![None.gif][]    @Override  
![None.gif][]    public String toString() \{  
![None.gif][]        return ToStringBuilder.reflectionToString(this);  
![None.gif][]    \}  
![None.gif][]\}  
![None.gif][]

![ExpandedBlockStart.gif][] public  class TestXmlToObject3  \{  
![InBlock.gif][]  
![InBlock.gif][]      public  static  final XStream xstream= new XStream();  
![InBlock.gif][]       
![ExpandedSubBlockStart.gif][]      static\{  
![InBlock.gif][]         xstream.processAnnotations(Person3. class); // 显示声明使用注解   
![InBlock.gif][]         xstream.autodetectAnnotations( true);  
![InBlock.gif][]         Person3 person=(Person3)xstream.fromXML(TestXmlToObject3. class.getClassLoader().getResourceAsStream("person03.xml"));  
![InBlock.gif][]         System.out.println(person.toString());  
![ExpandedSubBlockEnd.gif][]     \}

![InBlock.gif][]  
![ExpandedSubBlockEnd.gif][]    \}  
![InBlock.gif][]  
![ExpandedBlockEnd.gif][]\}
