Xstream jodatime 本地日期显示

我正在使用 xstrem 将 jodatime 本地日期序列化为 xml。 然而，当输出生成的 xml 时，LocalDate 的格式并不易于阅读。 见下文：

<date>
    <iLocalMillis>1316563200000</iLocalMillis>
    <iChronology class="org.joda.time.chrono.ISOChronology" reference="../../tradeDate/iChronology"/>

有什么想法可以让 xstream 以不会让我烦恼的格式显示日期吗？

这是我已经成功使用的。我相信我使用了第一篇文章中提到的链接中的信息。

import java.lang.reflect.Constructor;

import org.joda.time.DateTime;

import com.thoughtworks.xstream.converters.Converter;
import com.thoughtworks.xstream.converters.MarshallingContext;
import com.thoughtworks.xstream.converters.UnmarshallingContext;
import com.thoughtworks.xstream.io.HierarchicalStreamReader;
import com.thoughtworks.xstream.io.HierarchicalStreamWriter;


public final class JodaTimeConverter implements Converter {

    @Override
    @SuppressWarnings("unchecked")
    public boolean canConvert(final Class type) {
            return (type != null) && DateTime.class.getPackage().equals(type.getPackage());
    }

    @Override
    public void marshal(final Object source, final HierarchicalStreamWriter writer,
            final MarshallingContext context) {
            writer.setValue(source.toString());
    }

    @Override
    @SuppressWarnings("unchecked")
    public Object unmarshal(final HierarchicalStreamReader reader,
            final UnmarshallingContext context) {
            try {
                    final Class requiredType = context.getRequiredType();
                    final Constructor constructor = requiredType.getConstructor(Object.class);
                    return constructor.newInstance(reader.getValue());
            } catch (final Exception e) {
                throw new RuntimeException(String.format(
                 "Exception while deserializing a Joda Time object: %s", context.getRequiredType().getSimpleName()), e);
            }
    }

}

你可以这样注册：

XStream xstream = new XStream(new StaxDriver());
xstream.registerConverter(new JodaTimeConverter());
