XStream学习笔记四

XStream生成xml文件和从xml文件中得到对象

public class TestReadAndWrite {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		Person person=new Person();
		person.setName("张三");
		
		Calendar date=Calendar.getInstance();
		
		Birthday bir=new Birthday();
		bir.setDate(date);
		bir.setPerson(person);
		bir.setGenderMale();
		
		XStream stream=new XStream();
		stream.alias("birthday", Birthday.class);
		stream.alias("person", Person.class);
		stream.registerConverter(new BirthdayConverter2());
		
		stream.registerConverter(new DateConverter(Locale.CHINA));
		
		//生成xml文件
		try{
			//生成xml文件
			FileOutputStream fos = new FileOutputStream("D://1.xml");
			//为了防止乱码，指定文件输出的编码格式
			OutputStreamWriter writer = new OutputStreamWriter(fos, Charset.forName("GBK"));
			//xml文件头必须手工加上
			writer.write("<?xml version=\"1.0\" encoding=\"GBK\" ?>\n");
			stream.toXML(bir, writer);
			writer.close();
		}catch(Exception e){
			e.printStackTrace();
		}
		
		//从xml文件中得到对象
		try{
			
			FileInputStream fis = new FileInputStream("D://1.xml");
			//为了防止乱码，指定文件输出的编码格式
			InputStreamReader input = new InputStreamReader(fis, Charset.forName("GBK"));
			
			Birthday b=(Birthday) stream.fromXML(input);
			input.close();
		
			System.out.println("person.name"+b.getPerson().getName());
			System.out.println(".date:"+DateFormat.getDateInstance(DateFormat.FULL).format(
	               b.getDate().getTime()));
			System.out.println(".gender:"+b.getGender());
			
		}catch(Exception e2){
			e2.printStackTrace();
		}
