I want to store articles in my table where I want the published date to be generated automatically and stored in the database.
The column publishedDate in my article table shows NULL whenever I add the article. I want the date to be automatically inserted.How can I do so?
I have the following code in my entity class and JSP file
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@page import="java.util.Date" %>
<jsp:useBean id="now" class="java.util.Date" />
<c:url value="/admin/article/save" var="url"></c:url>
<form:form class="form-horizontal" action="${url}" modelAttribute="article"
method="POST" enctype="multipart/form-data" style="margin-top:5rem;" >
<fieldset>
<form:hidden path="articleViews" value="${article.articleViews}" />
<form:hidden path="publishedDate" id="publishedDate" value="${now}" />
<form:hidden path="articleId" value="${article.articleId}" />
