详细介绍JavaBean和XML互转工具类

使用XStream的jar包 x-stream.github.io/index.html jar包见附件 XStream is a simple library to serialize objects to XML and back again. 实体类

public class Person {  	   	 private String firstname;  	 private String lastname;  	 private PhoneNumber phone;  	 private PhoneNumber fax;  	   	 public Person(String firstname,String lastname){  		 this.firstname = firstname;   		 this.lastname = lastname;   	 }  	  	 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;  	}  	public PhoneNumber getPhone() {  		return phone;  	}  	public void setPhone(PhoneNumber phone) {  		this.phone = phone;  	}  	public PhoneNumber getFax() {  		return fax;  	}  	public void setFax(PhoneNumber fax) {  		this.fax = fax;  	}  	   	  }    public class PhoneNumber {  	private int code;  	private String number;  	  	public PhoneNumber(int code,String number){  		this.code = code;  		this.number = number;  	}  	  	public int getCode() {  		return code;  	}  	public void setCode(int code) {  		this.code = code;  	}  	public String getNumber() {  		return number;  	}  	public void setNumber(String number) {  		this.number = number;  	}  }

工具类

import com.thoughtworks.xstream.XStream;  import com.thoughtworks.xstream.io.xml.StaxDriver;  import com.wind.study.entity.Person;  import com.wind.study.entity.PhoneNumber;    /**   *   * @author wind  * @date 2016年9月13日 下午4:49:32   * @Description: bean/XML 互转   */  public class BeanXMLConvertUtil {  	  	public static void main(String[] args) {  		XStream xstream = new XStream(new StaxDriver());  		  		//XStream的XML输出更简洁,可以为您的自定义类名创建别名XML元素名称。这是唯一类型的映射需要使用XStream甚至是可选的。  		xstream.alias("person", Person.class);  		xstream.alias("phonenumber", PhoneNumber.class);  		  		Person joe = new Person("Joe", "Walnes");  		joe.setPhone(new PhoneNumber(123, "1234-456"));  		joe.setFax(new PhoneNumber(123, "9999-999"));  		  		//bean to XML  		String xml = xstream.toXML(joe);  		//XML to bean  		Person newJoe = (Person)xstream.fromXML(xml);  		  		System.out.println(newJoe.getFirstname());  		  		System.out.println(xml);  	}  }
