两行核心代码轻松搞定XML和对象间相互转换. XStream 简单示例.

import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.StringWriter;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
import javax.xml.bind.Unmarshaller;

public class XmlUtils {
	public static String objectToXml(Class<?> clazz, Object object)
			throws Exception {
		JAXBContext context = JAXBContext.newInstance(clazz);
		Marshaller marshaller = context.createMarshaller();
		StringWriter stringWriter = new StringWriter();
		marshaller.marshal(object, stringWriter);

		return stringWriter.toString();
	}

	public static Object xmlToObject(Class<?> clazz, String xml) throws Exception {
		JAXBContext context = JAXBContext.newInstance(clazz);
		Unmarshaller unmarshaller = context.createUnmarshaller();
		
		return unmarshaller.unmarshal(toInputStream(xml, "utf-8"));
	}

	private static InputStream toInputStream(String input, String encoding)
			throws IOException {
		byte[] bytes = (encoding != null) ? input.getBytes(encoding) : input
				.getBytes();
		return new ByteArrayInputStream(bytes);
	}
}
