需要引入xstream.jar包

import com.thoughtworks.xstream.XStream;


public class Son {
	
	
	public static void main(String[] args) {
		
		String my = "<person>" +
		            "<name>xulexun</name>" +
				    "<age>22</age>" +
		            "<sex>男</sex>" +
				    "<telphone>0571-8989765</telphone>" +
				    "</person>";
		XStream xStream = new XStream();
		xStream.alias("person",Person.class);
		Person person = (Person)xStream.fromXML(my);
		System.out.println(person.getName());
		System.out.println(person.getAge());
		System.out.println(person.getSex());
		System.out.println(person.getTelphone());
	}

}

JavaBean:

public class Person {
	
	private String name;
	private Integer age;
	private String sex;
	private String telphone;
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public Integer getAge() {
		return age;
	}
	public void setAge(Integer age) {
		this.age = age;
	}
	public String getSex() {
		return sex;
	}
	public void setSex(String sex) {
		this.sex = sex;
	}
	public String getTelphone() {
		return telphone;
	}
	public void setTelphone(String telphone) {
		this.telphone = telphone;
	}
}
