In this video, viewers will gain an understanding of cron jobs, including their architecture and the relationship between cron jobs, jobs, and triggers. The tutorial will guide the audience through the process of creating a custom cron job and setting up a trigger.
To create a cron job, one must start by defining a new cron job item type within a specific configuration file. Following that, a command is executed to compile the project. The next step involves creating a class that functions as a job by extending a specific base class and implementing a method where the business logic is defined. This class must then be registered as a bean within another configuration file.
After setting up the job class, a data script is written to establish instances of the cron job and trigger. Once again, the project is compiled, and the server is started. A system update is performed, followed by the execution of the previously written data script to finalize the setup.
For creating the data script, specific commands are included to insert or update job definitions and their associated configurations, such as unique identifiers, job codes, and scheduling expressions. This methodical approach ensures that the cron job operates as intended within the system.
