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
