This article describes job visualizations (management, imperfect visual management of this article) when using the job framework of spring (spring inherited and simplified quartz)The solution is to use listeners to implement job history, job statistics, exception logging, manual trigger JobLet's take a look at the implementation processHere you only need to implement several listeners and register to-Statis

In a recent spring MVC project, you need to perform a task regularly, so you use spring's own task functionality. When debugging locally, everything is fine, but once deployed to the server, each task is called two times. After searching for related problems on the Internet, excluding the problem of repeating annotatio

Java implements timed tasks typically using a timer, or using the quartz component. Now the spring boot provides a more convenient way to implement it.Spring boot has integrated the scheduled tasks. Use @secheduled annotations.@Component//Enable Scheduled Tasks@EnableScheduling Public classTagpushscheduler {Private StaticLogger log = Logger.getlogger (Tagpushscheduler.class); @Scheduled (cron = "0/10 * * * * *?") //executes once every 10 seconds P

It represents the value, if any, that is computed based on the associated calendar. If there is no associated calendar, it is equivalent to

continuous interval (9-12), a time interval (8-18/4) (/= every 4 hours), a list (1,3,5), and a wildcard character. * Because the "date in month" and "Day of the Week" are mutually exclusive, one of the two elements must be set?. */@Scheduled (Cron= "5 * * * *?")

In spring MVC, the container is loaded automatically when the project is started, but at ordinary times it needs to be done at the start of the project, which is used in the container, and can be accomplished by implementing the Applicationlistener interface. A class that implements the Applicationlistener interface that is notified whenever a applicationevent is published to the ApplicationContext (that is, the context, also known as a container), Ne
