利用XStream在Java对象和XML之间相互转换

利用XStream在Java对象和XML之间相互转换

XStream是个好东西，可以方便在Java对象和XML之间相互转换，效率和可读性都非常高，下面是我写的一个测试的例子.

需要的jar包如下：
xpp3_min-1.1.4c.jar
xstream-1.3.jar

目标：将Persons对象转换xml，再将xml转化为Persons对象。

实现源码列表：

// XStreamDemo.java [/b]
import com.thoughtworks.xstream.XStream;

import java.util.List;
import java.util.ArrayList;

/**

*/
public class XStreamDemo {
public static void main(String args[]) {
testBean2XML();
}

/**
* 生成一个Persons对象
*
* @return Persons对象
*/
public static Persons getPersons() {
Address add1 = new Address("type1", "郑州市经三路财富广场1");
Address add2 = new Address("type2", "郑州市经三路财富广场2");
List<Address> addlist1 = new ArrayList<Address>();
addlist1.add(add1);
addlist1.add(add2);

Address add3 = new Address("type3", "郑州市经三路财富广场3");
Address add4 = new Address("type4", "郑州市经三路财富广场4");
List<Address> addlist2 = new ArrayList<Address>();
addlist2.add(add3);
addlist2.add(add4);

Addresses addes1 = new Addresses(addlist1);
Addresses addes2 = new Addresses(addlist2);
Person person1 = new Person(addes1, "6666554", "lavasoft", "man");
Person person2 = new Person(addes2, "7777754", "yutian", "man");

List<Person> listPerson = new ArrayList<Person>();
listPerson.add(person1);
listPerson.add(person2);
Persons persons = new Persons(listPerson, "001");
return persons;
}

/**

public static void testBean2XML() {
System.out.println("将Java对象转换为xml！/n");
Persons persons = getPersons();
XStream xstream = new XStream();
xstream.alias("address", Address.class);
xstream.alias("addresses", Addresses.class);
xstream.alias("person", Person.class);
xstream.alias("persons", Persons.class);
String xml = xstream.toXML(persons);
System.out.println(xml);

System.out.println("/n将xml转换为Java对象！");
Persons cre_person = (Persons) xstream.fromXML(xml);
System.out.println(cre_person.toString());
}
}

}

}

运行测试类XStreamDemo，打印出结果：

将Java对象转换为xml！
