Java序列化的日期为是很标准，XStream中转换为标准的做法

 

import java.text.DateFormat;

import java.text.ParseException;

import java.text.SimpleDateFormat;

import java.util.Date;

import java.util.GregorianCalendar;

import java.util.Locale;

import com.thoughtworks.xstream.converters.ConversionException;

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 class DateConverter implements Converter {

 private Locale locale;

 public DateConverter(Locale locale) {

  super();

  this.locale = locale;

 }

 @Override

 public void marshal(Object value, HierarchicalStreamWriter writer,

   MarshallingContext context) {

  Date date = (Date) value;

  DateFormat formatter = new SimpleDateFormat(

    "yyyy-MM-dd'T'HH:mm:ss.SSS");

  // DateFormat formatter = DateFormat.getDateInstance(DateFormat.FULL,

  // this.locale);

  // 在这写输出的格式

  writer.setValue(formatter.format(date));

 }

 @Override

 public Object unmarshal(HierarchicalStreamReader reader,

   UnmarshallingContext context) {

  GregorianCalendar calendar = new GregorianCalendar();

  DateFormat formatter = DateFormat.getDateInstance(DateFormat.FULL,

    this.locale);

  try {

   calendar.setTime(formatter.parse(reader.getValue()));

  } catch (ParseException e) {

   throw new ConversionException(e.getMessage(), e);

  }

  return calendar;

 }

 @Override

 public boolean canConvert(Class clazz) {

  // return Calendar.class.isAssignableFrom(clazz);

  return Date.class.isAssignableFrom(clazz);

 }

}

 

去掉Java的包名等
