Json-lib反序列化自定义转换器

//先往注册器中注册变换器，需要用到ezmorph包中的类
JSONUtils.getMorpherRegistry().registerMorpher(new TimestampMorpher());

public class TimestampMorpher extends AbstractObjectMorpher {    
  @Override    
  public Class morphsTo() {
        return Timestamp.class;    
  }
  @Override    
  public Object morph(Object o) {
        try {
            return new Timestamp(DateUtil.parse(o.toString()).getTime());
        } catch (ParseException e) {
            e.printStackTrace();
        }
        return null;
  }
}
