获取当前年月日...信息的方法，获取请求的ip地址，获取 年-月-日 时:分:秒这种，Spring.xml文件为对象传list格式数据，JSP页面的小技巧（相当于include）

1、获取当前年月日...信息的方法

public class CommonDate {

    public final String year = String.valueOf(Calendar.getInstance().get(Calendar.YEAR));
    public final String month = String.valueOf(Calendar.getInstance().get(Calendar.MONTH)+1);
    public final String day = String.valueOf(Calendar.getInstance().get(Calendar.DAY_OF_MONTH));
    public final String hour_24 = String.valueOf(Calendar.getInstance().get(Calendar.HOUR_OF_DAY));
    public final String hour_12 = String.valueOf(Calendar.getInstance().get(Calendar.HOUR));
    public final String minute = String.valueOf(Calendar.getInstance().get(Calendar.MINUTE));
    public final String second = String.valueOf(Calendar.getInstance().get(Calendar.SECOND));
    public final String week_of_year = String.valueOf(Calendar.getInstance().get(Calendar.WEEK_OF_YEAR));
    public final String week_of_month = String.valueOf(Calendar.getInstance().get(Calendar.WEEK_OF_MONTH));
    public final String day_of_year = String.valueOf(Calendar.getInstance().get(Calendar.DAY_OF_YEAR));
    public final String day_of_month = String.valueOf(Calendar.getInstance().get(Calendar.DAY_OF_MONTH));
    public final String day_of_week = String.valueOf(Calendar.getInstance().get(Calendar.DAY_OF_WEEK));



    /**
     * 获取当前时间
     * @return 当前时间,24小时yyyy-MM-dd HH:mm:ss格式
     */
    public String getTime24(){
        Date date = new Date();
        SimpleDateFormat timeStamp = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        String time = timeStamp.format(date);
        return time;
    }

2、获取请求的ip地址

3、由于数据库中是time格式，所以要获取时分秒的格式

 

 

4、Spring.xml文件为对象传list格式数据
