这个例子是参照官网上面的例子写的： http://xstream.codehaus.org/tutorial.html

1.首先构造想要序列化的类

Person.java:

[java] 
    view plain 
    copy 
     
    
 publicclassPerson{
 privateStringfirstname;
privateStringlastname;
privatePhoneNumberphone;
privatePhoneNumberfax;
 //...constructorsandmethods
publicPerson(Stringfirstname,Stringlastname){
super();
this.firstname=firstname;
this.lastname=lastname;
 }
voidsetPhone(PhoneNumberphoneNumber){
this.phone=phoneNumber;
 }
voidsetFax(PhoneNumberphoneNumber){
this.fax=phoneNumber;
 @Override
publicStringtoString(){
return"FirstName:"+firstname+",LastName:"+lastname
 +"phone.Code:"+phone.getCode()+"phone.Number:"
 +phone.getNumber()+"fax:"+fax.getCode()+"fax.Number:"
 +fax.getNumber();
 }

PhoneNumber.java:

copy 
     
    

PhoneNumber{

privateintcode;
privateStringnumber;
publicPhoneNumber(intcode,Stringnumber){
this.code=code;
this.number=number;
intgetCode(){
returncode;
publicStringgetNumber(){
returnnumber;
}

2.初始化XStream并序列化和反序列化。

StreamxStream=newXStream();

你需要xstream-[version].jar and xpp3-[version].jar在classpath中。XPP3是一个非常快的XML拉式转换器工具。如果你不想包含这个依赖，你可以使用标准的JAXP DOM转换器来代替。

XStream xStream = new XStream(new DomDriver());//不需要XPP3库

这里要特别说明的是XStream xStream2=new XStream();这样会出错，使用原来的

copy 
     
    

XStreamTest{

staticvoidmain(String[]args)throwsFileNotFoundException{
//InitializingXStream
XStreamxStream=newXStream();
xStream.alias("person",Person.class);
xStream.alias("personnumber",PhoneNumber.class);
//SerializinganobjecttoXML
Personjoe=newPerson("Joe","Walnes");
joe.setPhone(newPhoneNumber(123,"1234-456"));
joe.setFax("9999-999"));
FileOutputStreamfileOutputStream=newFileOutputStream(newFile("test.xml"));
xStream.toXML(joe,fileOutputStream);
//DeserializinganobjectbackfromXM
XStreamxStream2= FileInputStreamfileInputStream=newFileInputStream(newFile("test.xml"));
Personperson=(Person)xStream.fromXML(fileInputStream);
System.out.println(person.toString());
}

看一下运行的结果：

test.xml:

[xhtml] 
    copy

firstname>Joe</>
lastname>Walnesphonecode>123number>1234-456fax>9999-999>
