Use spring timed tasks and monitor task execution through AOP

This article is about the implementation of task scheduling through spring annotations. As long as the Spring-context package is introduced, task scheduling can be used in the project annotated way.

See below for specific configuration
The schema of the task needs to be added to the spring configuration file.

xmlns:task="http://www.springframework.org/schema/task"xsi:schemaLocation="http://www.springframework.org/schema/task        http://www.springframework.org/schema/task/spring-task-4.0.xsd"

Then, when enable annotation support

<task:annotation-driven />

It can then be used directly in the code, and the method to be executed periodically must be void and without any arguments.

  @Override   @Scheduled  (cron=" 0 0 2 * *? ")  @Transactional     (Rollbackfor=exception.class) public  void  excute  () throws  dxpexception  

Cron expression Please ask Baidu yourself, here are just a few examples from the Internet to find
Cron expression meaning
"0 0 12 * *?" trigger 12 o'clock noon every day.
"0 15 10?" * * "trigger 10:15 every day"
"0 15 10 * *?" Daily 10:15 Trigger
"0 15 10 * *?" * "10:15 per day" trigger
"0 15 10 * *?" 2005 "2005-year daily 10:15 Trigger
"0 * 14 * *?" daily from 2 o'clock in the afternoon to 2:59 per minute trigger
"0 0/5 14 * *?" daily from 2 o'clock in the afternoon to 2:55 minutes end every 5 minute trigger
"0 0/5 14,18 * *?" daily from 2 o'clock in the afternoon to 2:55 and 6 to 6:55 every 5 minutes.
"0 0-5 14 * *?" daily from 14:00 to 14:05 per minute trigger
"0 10,44 14?" 3 WED "March of 14:10 and 14:44 triggers per Wednesday
"0 15 10?" * MON-FRI "10:15 triggers per Monday, Tuesday, Wednesday, Thursday, Friday

The implementation of the method is monitored through AOP and saved to the database

Where task annotations are the name of the callout task and are easy to save in the database
