On the jsp page, the 24-hour extraction time from the mysql database is displayed.

The display method is as follows: % @ tagliburijava. sun. comjspjstlfmtprefixfmt % fmt: formatDatevalue $ {music. addDatetime} patternyyyy-MM-ddHH: mm: ss indicates the red letter. If H is used, it is in the 24-hour format. If h is used, the 12-hour plan is complete.

Display Method: % @ taglib uri = http://java.sun.com/jsp/jstl/fmt prefix = fmt % fmt: formatDate value =$ {music. addDatetime} pattern = yyyy-MM-dd HH: mm: ss indicates the red letter. If H is used, it is in the 24-hour format. If h is used, the 12-hour plan is complete.

The display method is as follows:

<% @ Taglib uri = "http://java.sun.com/jsp/jstl/fmt" prefix = "fmt" %>

The key lies in the red letter. If the Big H is used, it is in the 24-hour format. If the small h is used, it is in the 12-hour format.

It's done.
