后台解决 json-lib封装的时间 - JAVA

1. Json-lib可以将 Java对象很方便的转成json格式的字符串,使用教程(http://json-lib.sourceforge.net/usage. html)
但是当Java对象中有时间类型的时候。 Json-lib会把时间字段转换成：
{"date":17,"day":3,"hours":0,"minutes":0,"month":11,"nanos":0,"seconds":0,"time":345830400000,"timezoneOffset":-480,"year":80},"ENAME":"SMITH"}
如何处理呢？
第一种(extjs中处理的)：http://blog.csdn.net/without0815/article/details/7788582
第二种(主要)：
[java]
List list=iEmpDao.getListEmp(pageIndex, pageNo);

//Map map = (Map)list.get(0);
//JSONArray ja1=new JSONArray().fromObject(list);
JSONArray ja = new JSONArray();
JsonConfig jf = new JsonConfig();
//jf.registerJsonValueProcessor(java.sql.Timestamp.class, new DateJsonValueProcessor("yyyy-MM-dd HH:mm:ss"));
jf.registerJsonValueProcessor(java.sql.Timestamp.class, new DateJsonValueProcessor("yyyy-MM-dd"));
jf.registerJsonValueProcessor(java.util.Date.class, new DateJsonValueProcessor("yyyy-MM-dd"));
System.out.println(ja.fromObject(list,jf).toString());

return ja.fromObject(list,jf).toString();
DateJsonValueProcessor是实现了一个JsonValueProcessor接口
[java] view plaincopy
package org.ymm.util;

import java.text.SimpleDateFormat;
import net.sf.json.JsonConfig;
import net.sf.json.processors.JsonValueProcessor;

public class DateJsonValueProcessor implements JsonValueProcessor
{

private String format;

public DateJsonValueProcessor(String format){
this.format = format;
}

public Object processArrayValue(Object value, JsonConfig jsonConfig)
{
return null;
}

public Object processObjectValue(String key, Object value, JsonConfig jsonConfig)
{
if(value == null)
{
return "";
}
if(value instanceof java.sql.Timestamp)
{
String str = new SimpleDateFormat(format).format((java.sql.Timestamp)value);
return str;
}
if (value instanceof java.util.Date) www.2cto.com
{
String str = new SimpleDateFormat(format).format((java.util.Date) value);
return str;
}

return value.toString();
}
}
只要是时间类型被处理格式化
