This article mainly introduces the jspXCMS how to develop timing tasks related knowledge, the content is detailed and easy to understand, the operation is simple and fast, has a certain reference value, I believe that everyone after reading this jspXCMS how to develop timing tasks article will have a harvest, let's take a look.

There are scheduled tasks in the system, and there are some task types that have been defined by the system. If the task type that comes with the system does not have its own needs, you can develop a task type.

In line with the idea of non-intrusive secondary development design, it is possible to develop one's own task type without modifying the original code and files of the system.

Scheduled task profile

Jspxcms8.0 and later versions:

/ src/main/resources/conf/conf.properties

Jspxcms6.5-7.5 version:

/ src/main/resources/conf/application.properties

Jspxcms6.0 and previous versions:

/ WEB-INF/conf/application.properties

Related configuration content:

ScheduleJob.100=com.jspxcms.core.quartz.InfoPublishJobscheduleJobPath.com.jspxcms.core.quartz.InfoPublishJob=scheduleJob.200=com.jspxcms.core.quartz.HtmlHomeJobscheduleJobPath.com.jspxcms.core.quartz.HtmlHomeJob=scheduleJob.300=com.jspxcms.ext.quartz.CollectJobscheduleJobPath.com.jspxcms.ext.quartz.CollectJob=/cmscp/ext/collect/schedule_job.do

The configuration of custom scheduled task types can also be written in other conf.properties files, such as / src/main/resources/conf/plugin/plug/conf.properties.

Scheduled task type serial number

ScheduleJob.300: serial number 300 determines the sort of this type, that is, the order before and after the task type is selected. The serial number cannot be repeated.

Scheduled task name

Com.jspxcms.ext.quartz.CollectJob is both a timed task implementation class and a timed task type name. The corresponding internationalization name needs to be defined in the internationalization file.

Internationalized files (Jspxcms6.5 and later): / src/main/resources/messages/ext/ext.properties

Internationalization files (Jspxcms6.0 and previous versions): / WEB-INF/messages/ext/ext.properties

ScheduleJob.code.com.jspxcms.ext.quartz.CollectJob= acquisition

Need to use scheduleJob.code. The beginning. The internationalization name can also be written in other files, such as / src/main/resources/messages/plugin/plug/plug.properties.

Timed task implementation class

Com.jspxcms.ext.quartz.CollectJob is a timed task implementation class.

Public class CollectJob implements Job {private static final Logger logger = LoggerFactory .getLogger (CollectJob.class); public static final String COLLECT_ID = "collectId"; public void execute (JobExecutionContext context) throws JobExecutionException {try {ApplicationContext appContext = (ApplicationContext) context .getScheduler (). GetContext (). Get (Constants.APP_CONTEXT); Collector collector = appContext.getBean (Collector.class) JobDataMap map = context.getJobDetail (). GetJobDataMap (); Integer collectId = map.getIntegerFromString (COLLECT_ID); collector.start (collectId); System.out.println ("collect ok"); logger.info ("run collect job:" + collectId);} catch (SchedulerException e) {throw new JobExecutionException ("Cannot get ApplicationContext", e);}

You need to implement the org.quartz.Job interface and write the code that the task needs to perform in the public void execute (JobExecutionContext context) method.

ApplicationContext appContext = (ApplicationContext) context.getScheduler () .getContext () .get (Constants.APP_CONTEXT); you can get the ApplicationContext of Spring, and the objects managed by Spring can be obtained through ApplicationContext, such as Collector collector = appContext.getBean (Collector.class);. Note: this method must be used in this class to get Spring-managed objects, not in other ways such as @ Autowired.

Integer collectId = map.getIntegerFromString (COLLECT_ID); additional parameters can be obtained.

Additional parameters

ScheduleJobPath.com.jspxcms.core.quartz.InfoPublishJob= if no additional parameters are needed for a scheduled task, leave a blank after the equal sign.

Timing tasks sometimes need to pass non-parameters, such as collection timing tasks need to choose which collection data source to execute. At this point, you need to add corresponding entries in the scheduled task add / modify interface.

ScheduleJobPath.com.jspxcms.ext.quartz.CollectJob=/cmscp/ext/collect/schedule_job.do

Input Controller of the interface

Write an address to get the input interface: / cmscp/ext/collect/schedule_job.do, where the relative path is used to add the address of the interface relative to the scheduled task.

In this case, the implementation class for this address is com.jspxcms.ext.web.back.CollectController.

@ Controller@RequestMapping ("/ ext/collect") public class CollectController {. @ RequestMapping ("schedule_job.do") public String scheduleJob (HttpServletRequest request, org.springframework.ui.Model modelMap) {Integer siteId = Context.getCurrentSiteId (); List collectList = service.findList (siteId); modelMap.addAttribute ("collectList", collectList); modelMap.addAttribute ("includePage", ".. / ext/collect/collect_job.jsp") Return "core/schedule_job/schedule_job_form";}.}

ModelMap.addAttribute ("collectList", collectList); pass data.

ModelMap.addAttribute ("includePage", ".. /.. / ext/collect/collect_job.jsp"); transfer input interface.

Input JSP of the interface

According to the value of includePage passed in Controller, the corresponding JSP page is: / WEB-INF/views/ext/collect/collect_job.jsp.

: ${collect.name}

The data_collectId here corresponds to the method Integer collectId = map.getIntegerFromString ("collectId") for obtaining parameters in the timed task implementation class CollectJob

: ${collectList} here corresponds to CollectController's modelMap.addAttribute ("collectList", collectList);.
