Date 公共类整理

项目中用到的时间的公共类,整理出来,呵呵!!

public class DateUtil {

?// 定义常量
?public static final String yyyyMMdd = "yyyy-MM-dd"; // 精确到天
?public static final String yyyyMMddmm = "yyyy-MM-dd hh:mm:00"; // 精确到分(秒为补零)
?public static final String HHmmss = "HH:mm:ss";
?public static final String yyyyMMddHHmmss = "yyyy-MM-dd HH:mm:ss"; // 精确到秒
?public static final String yyMMddHHmmss = "yy-MM-dd HH:mm:ss";

?/**
? * <pre>
? * 根据plDateLine参数和pstrStyle参数,格式返回日期.
? * </pre>
? *
? * @param plDateLine long
? * @param pstrStyle? String
? * @return mstrDate
? * @author aa00aa00?2011-5-19
? */
?public static String parseToDate(long plDateLine, String pstrStyle) {
??SimpleDateFormat objFormatter = new SimpleDateFormat();
??objFormatter.applyPattern(pstrStyle);
??Date objDate = null;
??String mstrDate = null;
??try {
???objDate = new Date(plDateLine);
???mstrDate = objFormatter.format(objDate);
??} catch (Exception e) {
???return "";
??}
??return mstrDate;
?}

?

2.调用方式举例:

// 评论时间戳
??objCommentDTO.setMstrCreatedtime(DateUtil.parseToDate(
????pobComment.getMnCreatedtime() * 1000l, DateUtil.yyyyMMddmm));
