Writing Example
In this example we will use DateBean action class to get the current date of the system. This current date will be used in our example. Here is the code of DateBean.java
package net.roseindia;
|
Add the following entry in the struts.xml file in order to create action mapping:
<action name="FormatDate" class="net.roseindia.DateBean">
<result>/pages/dateformat.jsp</result>
</action>
Following jsp file(dateformat.jsp) shows the usage of date tag:
<%@ taglib prefix="s" uri="/struts-tags" %> <html> <head> <title>Struts 2 Format Date Example!</title> <link href="<s:url value="/css/main.css"/>" rel="stylesheet" type="text/css"/> </head> <body> <s:form action="FormatDate" method="POST"> <tr> <td>Date in (yyyy-MM-dd) Format:</td> <td> <b><s:date name="todayDate" format="yyyy-MM-dd" /></b> </td> </tr> <tr> <td>Date in (MM/dd/yyyy hh:mm AM/PM) Format:</td> <td> <b><s:date name="todayDate" format="MM/dd/yyyy 'at' hh:mm a" /></b> </td> </tr> <tr> <td>Date in (dd-MMM-yyyy hh:mm AM/PM) Format:</td> <td> <b><s:date name="todayDate" format="dd-MMM-yyyy 'at' hh:mm a" /></b> </td> </tr> <tr> <td>Date in (dd/MM/yyyy hh:mm) Format:</td> <td> <b><s:date name="todayDate" format="dd/MM/yyyy hh:mm" /></b> </td> </tr> <tr> <td>Nice Format:</td> <td> <b><s:date name="todayDate" format="yyyy-MM-dd" nice="true"/></b> </td> </tr> </s:form> </body> </html> |
