Daemon
Definition
A daemon is a process that runs at regular intervals. Lutece has a centralized interface for managing daemons. Each daemon has its own frequency of execution. In addition, he must provide a report of the treatment carried out. This one is thus searchable in the daemons management interface.
Creation
Implementation
A daemon must extend Lutece's Daemon class. The only method to implement is the run method within which you must call the setLastRunLogs method to pass the execution report to it.
import en.paris.lutece.portal.service.daemon.Daemon;
/ **
* My Daemon
* /
public class MyDaemon extends Daemon
{
/ **
* {@inheritDoc}
* /
@Override
public void run( )
{
setLastRunLogs( MyProcess ( ) );
}
}Declaration
The Daemon must be declared in 2 places :
Declaration in the plugin XML file
This declaration defines the Java class of the daemon as well as the name and description of the daemon by its i18n keys (to manage the language of the user who consults the centralized interface).
