I want to set up a cron job that sends an email every 2 minutes. However, when I initiate the cron job, it sends an email right away and then never again. But, when I go to the Google Cloud Console and look at my cron jobs, it says it's running successfully, but I'm not receiving emails.
I followed this tutorial: https://rominirani.com/episode-9-using-the-cron-service-to-run-scheduled-tasks-8bc7dba91a77
web.xml file:
<servlet>
<servlet-name>subscribe</servlet-name>
<servlet-class>blogapp.CronServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>subscribe</servlet-name>
<url-pattern>/subscribe</url-pattern>
</servlet-mapping>
cron.xml file:
<cronentries>
<cron>
<url>/subscribe</url>
<description>Daily Digest from The Rambling Programmer</description>
<!-- <schedule>every day 17:00</schedule> -->
<schedule>every 2 minutes</schedule>
<timezone>America/Chicago</timezone>
</cron>
</cronentries>
CronServlet.java file:
public class CronServlet extends HttpServlet {
private static final Logger _logger = Logger.getLogger(CronServlet.class.getName());
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws IOException {
try {
_logger.info("Cron Job has been executed");
/// other logic to send email
/// sendEmail(email, subject, content);
}
resp.sendRedirect("/subscribe.jsp");
}
catch (Exception ex) {
resp.getWriter().println("Error subscribing");
}
}
@Override
public void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
doGet(req, resp);
}
There's no errors popping up and one email successfully sends so I'm not sure why it's not running every two minutes like I wanted it to.
Thank you!
