xml 与 javaBean 互换

   在工作中经常遇到到另外一个服务器读取数据，其中一种最常用的方法，就是用xml进行数据传递，比如A服务器到B服务器得到对应的xml格式的数据，A得到之后进行解析。一般这种解析分为DOM解析和SAX解析。这里不是探讨DOM与SAX解析的区别和优点，只是介绍一个小框架，实现JAVABean和XML的转换，傻瓜式的转换。---------------------------XStream

JAVAbEAN---->XML
咱们首先得一个对象,比如这个对象是Person
public class Persone {
private String firstName;
private String lastName;
private PhoneNumber phone;
private PhoneNumber fax;

public Persone(String firstName, String lastName) {
super();
this.firstName = firstName;
this.lastName = lastName;
}
public Persone() {
super();
}
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;
}


}
对象PhoneNumber
public class PhoneNumber {
private int code;
private String 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;
}
public PhoneNumber(int code, String number) {
super();
this.code = code;
this.number = number;
}
public PhoneNumber() {
super();
}

}
  XStream xstream = new XStream(new DomDriver()); //初使化XStream
  xstream.alias("person", Persone.class);//对Persone.class名一个别名
  xstream.alias("phonenumber", PhoneNumb
