處理封裝好了的json時間

1.   Json-lib可以将Java對象很友善的轉成json格式的字元串，但是當Java對象中有時間類型的時候。 Json-lib會把時間字段轉換成：

{"date":17,"day":3,"hours":0,"minutes":0,"month":11,"nanos":0,"seconds":0,"time":345830400000,"timezoneOffset":-480,"year":80},"ENAME":"SMITH"}

如何處理呢？

1.json傳過來的時間參數

"HIREDATE":{"date":17,"day":3,"hours":0,"minutes":0,"month":11,"nanos":0,"seconds"              :0,"time":345830400000,"timezoneOffset":-480,"year":80},"ENAME":"SMITH"}
           

extjs得到time(秒計算):

[javascript] view plain copy print ?

1. flieds:{name : 'HIREDATE', type : 'date', mapping : 'HIREDATE.time', dateFormat : 'time'}  

flieds:{name : 'HIREDATE', type : 'date', mapping : 'HIREDATE.time', dateFormat : 'time'}
           

[javascript] view plain copy print ?

1. //格式化時間類型  
2.     function formatDate(value){  
3.          return value ? value.dateFormat('Y-m-d') : '';   
4.     }  

第二種(主要)：

[java] view plain copy print ?

1. List list=iEmpDao.getListEmp(pageIndex, pageNo);  
2.         //Map<String,Object> map = (Map<String,Object>)list.get(0);  
3.         //JSONArray ja1=new JSONArray().fromObject(list);  
4.         JSONArray ja = new JSONArray();  
5.         JsonConfig jf = new JsonConfig();  
6.         //jf.registerJsonValueProcessor(java.sql.Timestamp.class, new DateJsonValueProcessor("yyyy-MM-dd HH:mm:ss"));  
7.         jf.registerJsonValueProcessor(java.sql.Timestamp.class, new DateJsonValueProcessor("yyyy-MM-dd"));  
8.         jf.registerJsonValueProcessor(java.util.Date.class, new DateJsonValueProcessor("yyyy-MM-dd"));  
9.         System.out.println(ja.fromObject(list,jf).toString());        
10.         return  ja.fromObject(list,jf).toString();  

List list=iEmpDao.getListEmp(pageIndex, pageNo);
		
		//Map<String,Object> map = (Map<String,Object>)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是實作了一個JsonValueProcessor接口

[java] view plain copy print ?

1. package org.ymm.util;  
2. import java.text.SimpleDateFormat;  
3. import net.sf.json.JsonConfig;  
4. import net.sf.json.processors.JsonValueProcessor;  
5. public class DateJsonValueProcessor implements JsonValueProcessor  
6. {  
7.     private String format;  
8.     public DateJsonValueProcessor(String format){  
9.         this.format = format;  
10.     }  
11.     public Object processArrayValue(Object value, JsonConfig jsonConfig)  
12.     {  
13.         return null;  
14.     }  
15.     public Object processObjectValue(String key, Object value, JsonConfig jsonConfig)  
16.     {  
17.         if(value == null)  
18.         {  
19.             return "";  
20.         }  
21.         if(value instanceof java.sql.Timestamp)  
22.         {  
23.             String str = new SimpleDateFormat(format).format((java.sql.Timestamp)value);  
24.             return str;  
25.         }  
26.         if (value instanceof java.util.Date)  
27.         {  
28.             String str = new SimpleDateFormat(format).format((java.util.Date) value);  
29.             return str;  
30.         }  
31.         return value.toString();  
32.     }  
33. }  

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)
        {
            String str = new SimpleDateFormat(format).format((java.util.Date) value);
            return str;
        }
        
        return value.toString();
    }
}
           

隻要是時間類型被處理格式化
