JAXB实现XML和实体对象互转

通过JAXB实现XML和实体对象的互转，代码如下：

import java.io.IOException;
import java.io.StringReader;
import java.io.StringWriter;

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

import org.apache.log4j.Logger;

import com.shch.shclearing.business.log.CustomerLog;



public class JaxbUtil {

	private static Logger logger = Logger.getLogger(JaxbUtil.class);


	public static String convertToXml(Object object,String encoding) {

		String result = null;
		StringWriter writer = null;

		try {

			JAXBContext context = JAXBContext.newInstance(object.getClass());
			Marshaller marshaller = context.createMarshaller();
			marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT,true);
			marshaller.setProperty(Marshaller.JAXB_ENCODING,encoding);

			writer = new StringWriter();
			marshaller.marshal(object,writer);
			result = writer.toString();
			CustomerLog.customerLog(logger,"对象转换XML成功");

		} catch (Exception ex) {
			logger.error(object.getClass().getName() + "对象转换Xml失败",ex);
		} finally {
			if (writer != null) {
				try {
					writer.close();
				} catch (IOException e) {
					logger.error("StringWriter对象关闭失败",e);
				}
			}
		}
		return result;

	}

	@SuppressWarnings("unchecked")
	public static <T> T covertToObject(String xml,Class<T> c) {

		T t = null;
		StringReader reader = null;

		try {

			JAXBContext context = JAXBContext.newInstance(c);
			Unmarshaller unmarshaller = context.createUnmarshaller();
			reader = new StringReader(xml);
			t = (T) unmarshaller.unmarshal(reader);
			CustomerLog.customerLog(logger,"XML转换对象成功");

		} catch (Exception ex) {
			logger.error("Xml转换成对象失败",ex);
		} finally {
			if (reader != null) {
				try {
					reader.close();
				} catch (Exception e) {
					logger.error("StringReader对象关闭失败",e);
				}
			}
		}
		return t;

	}


}
