JAVA 怎么将时间戳转为2015-10-05T21:02:49.228Z 这种格式

//change formation of long to Date
private String transformDataFormation(long source){
    SimpleDateFormat sdf= new SimpleDateFormat("yyyy-dd-MM  HH:mm:ss");
    //前面的lSysTime是秒数，先乘1000得到毫秒数，再转为java.util.Date类型
    java.util.Date dt = new Date(source);
    String sDateTime = sdf.format(dt);  //得到精确到秒的表示：08/31/2006 21:08:00
    Log.i("blb", "---------time:" + sDateTime);
    return sDateTime;
}

自己看看想转成啥格式 自己改下就行了。

String time =  DateUtil.format(new Date(),"yyyy-MM-dd");

 public static Date fromISODate(String time){  
    if(!time.matches("\\d{4}-\\d{2}-\\d{2}T\\d{2}:\\d{2}:\\d{2}.\\d{3}Z")){  
        return null;  
    }  
    time=time.replaceFirst("T", " ").replaceFirst(".\\d{3}Z", "");  
    Date date=formatDate(time);  
    Calendar ca=Calendar.getInstance();  
    ca.setTime(date);  
    ca.add(Calendar.HOUR_OF_DAY, 8);  
    return ca.getTime();  
}  

String time = DateUtil.format(new Date(),"yyyy-MM-ddTHH:mm:ss.SSSZ");

SimpleDateFormat sdf= new SimpleDateFormat("yyyy-dd-MM HH:mm:ss");
sdf.prase(str)

最后一个Z表明是这个时间是0时区，不能用Java虚拟机的默认时区来转换，也不应该写死为东八区。

**Java转换UTC时间:2015-10-13T14:15:44.000Z **

public class TimeZoneTest

{

public static void main (String args[])

try

{

String ts = "2007-10-23T17:15:44.000Z";

System.out.println("ts = " + ts);

ts = ts.replace("Z", " UTC");

System.out.println("ts = " + ts);

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS Z");

                     Date dt = sdf.parse(ts);   


                     TimeZone tz = sdf.getTimeZone();

                     System.out.println("Display name: " +   

tz.getDisplayName());

System.out.println(getString(c));

}

catch(ParseException pe)

{

System.out.println("Error offset: " + pe.getErrorOffset());

pe.printStackTrace();

}

}

    private static String getString(Calendar c)

            StringBuffer result = new StringBuffer();   
            result.append(c.get(Calendar.YEAR));   
            result.append("-");   
            result.append((c.get(Calendar.MONTH) + 1));
