首先下载XStream-X.X.X.jar包，然后加载到类路径下。例子代码如下：
import java.io. * ; import java.beans. * ; import com.thoughtworks.xstream. * ; import com.thoughtworks.xstream.io.xml. * ; public class Test ... { /** *//** * @param args * @throws IOException * @throws ClassNotFoundException */ public static void main(String[] args) throws IOException, ClassNotFoundException ...{ // TODO Auto-generated method stub jdkReader(); } public static void xstreamWriter() throws IOException...{ FileWriter fw = new FileWriter("out.xml",true); XStream xstream = new XStream(); ObjectOutputStream out = xstream.createObjectOutputStream(fw); out.writeObject(new Person("Joe", "Walnes")); out.writeObject(new Person("Someone", "Else")); out.writeObject("hello"); out.writeInt(12345); out.close(); } public static void xstreamReader() throws IOException, ClassNotFoundException...{ FileReader fr = new FileReader("out.xml"); XStream xstream = new XStream(new DomDriver()); ObjectInputStream in = xstream.createObjectInputStream(fr); Person a = (Person)in.readObject(); Person b = (Person)in.readObject(); String c = (String)in.readObject(); int d = in.readInt(); System.out.println(a.getFirstName()); System.out.println(b.getFirstName()); System.out.println(c); System.out.println(d); } public static void jdkWriter() throws FileNotFoundException...{ XMLEncoder e = new XMLEncoder(new BufferedOutputStream(new FileOutputStream("Test.xml"))); e.writeObject(new Person("Hello,","world")); e.close(); } public static void jdkReader() throws FileNotFoundException...{ XMLDecoder d = new XMLDecoder(new BufferedInputStream(new FileInputStream("Test.xml"))); Person p = (Person)d.readObject(); d.close(); System.out.println(p.getFirstName()); } } public class Person ... { private String firstName; private String lastName; public Person()...{ } public Person(String afirstName,String alastName)...{ firstName = afirstName; lastName = alastName; } public String getFirstName() ...{ return firstName; } public void setFirstName(String firstName) ...{ this.firstName = firstName; } public String getLastName() ...{ return lastName; } public void setLastName(String lastName) ...{ this.lastName = lastName; } } jdk提供的方法只能对JavaBean对象进行序列化，所以具有局限性，而且只能序列化xxxSetter(),xxxGetter,removeXXX()方法。
