How to configure Quartz in Spring

Quartz is a powerful enterprise-level task scheduling framework. Spring inherits and simplifies Quartz. Let's see how to configure Quartz

Spring configuration files in Spring:


<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>
 
  <!-- Timer factory -->

timing tasks to run ; public class OrderAutoJob { public void run() {






System.out.println("OrderAutoJob timing start....");

System.out.println("OrderAutoJob timing end....");
}
}


测试程序:
package Test;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestAutoOrder {
public static void main(String[] args) {
System.out.println("Test start.");
                ApplicationContext context = new ClassPathXmlApplicationContext("spring/applicationContext.xml");
                System.out.print("Test end..");      hours seconds minutes Cron expressions include the following 7 fields: About cron expressions (from the web): }
}










day of
month month
week
year (optional field)


Cron triggers take advantage of a series of special characters as follows: The

backslash (/) character represents an incremental value. For example, "5/15" in the seconds field means every 15 seconds starting at the 5th second.

The question mark (?) character and the letter L character are only available in day-of-month and day-of-week fields. A question mark indicates that the field does not contain a specific value. So, if you specify a day of the month, you can insert a "?" in the day of the week field, indicating that the day of the week value doesn't matter. The letter L character is short for last. Placed in the date of the month field, it means that it is scheduled to be executed on the last day of the month. In the day of the week field, if "L" exists alone, it is equal to "7", otherwise it represents the last instance of the day of the week in the current month. So "0L" means that it is scheduled to execute on the last Sunday of the month.

The letter (W) character in the day-of-month field schedules execution on the weekday closest to the specified value. Putting "1W" in the date of month field means to schedule execution on the first working day of the month.

The pound (#) character specifies a specific weekday instance for a given month. Put "MON#2" in the day of the week field to schedule the task on the second Monday of the month.

The asterisk (*) character is a wildcard character, meaning that the field can accept any possible value.
