如下代碼：
[java]
StringBuilder sb = new StringBuilder("[");
sb.append("{");
sb.append("cremindTitle:\"小名\",");
sb.append("cremindDate:\"2012-06-05 19:20:22\",");
sb.append("cremindRemark:\"阿斯蒂芬\"");
sb.append("}");
sb.append("]");
List<Cremind> clist = JSONArray.toList(JSONArray.fromObject(sb.toString()),
Cremind.class);
在執行中會報錯,原因是由於日期類型字串到日期類型Timestamp的轉換，解決思路如下：
編寫一個Morpher類繼承自AbstractObjectMorpher
[java]
class TimeStampMorpher extends AbstractObjectMorpher{
private Logger LOG = Logger.getLogger(TimeStampMorpher.class);
private String format ="yyyy-MM-dd hh:mm:ss";
public void setFormat(String format) {
this.format = format;
}
public TimeStampMorpher() {
// TODO Auto-generated constructor stub
}
public TimeStampMorpher(String format) {
this.format = format;
}
@Override
public Object morph(Object dateStr) {
// TODO Auto-generated method stub
try {
java.util.Date date = new SimpleDateFormat(format).parse(dateStr.toString());
return new Timestamp(date.getTime());
} catch (ParseException e) {
// TODO Auto-generated catch block
if (LOG.isInfoEnabled())
LOG.info("日期格式可能無效,將采用系統當前日期");
e.printStackTrace();
}
return new java.sql.Timestamp(System.currentTimeMillis());//返回默認日期
}
@Override
public Class morphsTo() {
// TODO Auto-generated method stub
return Timestamp.class;
}
}
最終處理版本：
[java]

import java.sql.Timestamp;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.List;
import org.apache.log4j.Logger;

}
public TimeStampMorpher() {
// TODO Auto-generated constructor stub
}
public TimeStampMorpher(String format) {
this.format = format;
}
@Override
public Object morph(Object dateStr) {
// TODO Auto-generated method stub
try {
java.util.Date date = new SimpleDateFormat(format).parse(dateStr.toString());
return new Timestamp(date.getTime());
} catch (ParseException e) {
// TODO Auto-generated catch block
if (LOG.isInfoEnabled())
LOG.info("日期格式可能無效,將采用系統當前日期");
e.printStackTrace();
}
return new java.sql.Timestamp(System.currentTimeMillis());//返回默認日期
}
@Override
public Class morphsTo() {
// TODO Auto-generated method stub
return Timestamp.class;
}
}
public final class JsonUtil {

public static final <T> List<T> jsonArrayToList(String jsonArray,Class classzz){
JSONUtils.getMorpherRegistry().registerMorpher(new TimeStampMorpher());
// JSONUtils.getMorpherRegistry().registerMorpher(new TimeStampMorpher());
// StringBuilder sb = new StringBuilder("[");

}
