How to use custom type handler (typeHandler) in ibatis 2.3.4

i am using ibatis to replace JDBC in a old system. Many old bean are using Calendar instead of Date。So i am considering write aTypeHandlerCallbackto handler the translation.

the class implement TypeHandlerCallback:

public class CalendarTypeHandlerCallback implements TypeHandlerCallback {

 public Object getResult(ResultGetter getter) throws SQLException {
  String s = getter.getString();
  DateFormat format = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
  Calendar cdate = Calendar.getInstance();
  try {
   Date date = format.parse(s);
   cdate.setTime(date);
  } catch (Exception e) {
  }
  return cdate;
 }

 public void setParameter(ParameterSetter setter, Object parameter)
   throws SQLException {
  Calendar cdate = (Calendar)parameter;
  java.sql.Timestamp time = new java.sql.Timestamp(cdate.getTimeInMillis());
  setter.setTimestamp(time);
 }

 public Object valueOf(String s) {
  Calendar cdate = Calendar.getInstance();
  DateFormat format = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
  try {
   Date date = format.parse(s);
   cdate.setTime(date);
  } catch (Exception e) {
  }
  return cdate;
 }

}
