我有以下界面:
public interface Ranged
{
public Object getRangeStart();
public Object getRangeEnd();
public void setRangeStart(Object rangeStart);
public void setRangeEnd(Object rangeEnd);
}
以及以下实施类:
public class DateRange implements Ranged, Serializable
{
private static final long serialVersionUID=SerialVersionUID.getSerialVersionUID();
public DateRange()
{
}
private Date dateFrom;
private Date dateTo;
public Object getRangeStart()
{
return (Date)dateFrom;
}
public Object getRangeEnd()
{
return (Date)dateTo;
}
public void setRangeStart( Object from )
{
this.dateFrom = (Date)from;
}
public void setRangeEnd( Object to )
{
this.dateTo = (Date)to;
}
}
我以下列方式使用DateRange类:
...
private DateRange creationDate;
private Date rangeStart;
private Date rangeStop;
...
public DateRange getCreationDate()
{
SimpleDateFormat sdf_incoming = new SimpleDateFormat("yyyy-MM-dd");
SimpleDateFormat sdf_outgoing = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
creationDate = null;
try
{
if (!isDateRange())
{
if (!rangeStart.toString().equals(""))
{
creationDate = new DateRange();
creationDate.setRangeStart(sdf_outgoing.parse(sdf_incoming.format(rangeStart) + TIME_0));
creationDate.setRangeEnd(sdf_outgoing.parse(sdf_incoming.format(rangeStart) + TIME_24));
}
}
else
{
if (!rangeStart.toString().equals("") && rangeStop.toString().equals(""))
{
creationDate = new DateRange();
creationDate.setRangeStart(sdf_outgoing.parse(sdf_incoming.format(rangeStart) + TIME_0));
creationDate.setRangeEnd(sdf_outgoing.parse(MAX_DATE));
}
else if (rangeStart.toString().equals("") && !rangeStop.toString().equals(""))
{
creationDate = new DateRange();
creationDate.setRangeStart(sdf_outgoing.parse(MIN_DATE));
creationDate.setRangeEnd(sdf_outgoing.parse(sdf_incoming.format(rangeStop) + TIME_24));
}
else
// both set
{
creationDate = new DateRange();
creationDate.setRangeStart(sdf_outgoing.parse(sdf_incoming.format(rangeStart) + TIME_0));
creationDate.setRangeEnd(sdf_outgoing.parse(sdf_incoming.format(rangeStop) + TIME_24));
}
}
}
catch (ParseException e)
{
e.printStackTrace();
}
return creationDate;
}
...
这发生在客户端,当creationDate应序列化并传递到服务器端时,我收到以下错误:

我错过了什么吗？我真的迷路了.DateRange实现Serializable和(java.util)Date也应该是可序列化的.如果需要更多信息,请告诉我.
