第一种方式:

1 <%
2     java.text.SimpleDateFormat simpleDateFormat = new java.text.SimpleDateFormat(
3      "yyyy-MM-dd HH:mm:ss");
4    java.util.Date currentTime = new java.util.Date();
5    String time = simpleDateFormat.format(currentTime).toString();
6    out.println("当前时间为:"+time);
7      %>

第二种方式

1 <%! String formatDate(Date d){
2      java.text.SimpleDateFormat formater=
3      new java.text.SimpleDateFormat("yyyy年MM月dd日");
4      return formater.format(d);
5      }
6      %>
7      <%=formatDate(new Date()) %>
