Spring + Quartz achieve timing tasks maven full demo (idea)

Examples

Below each category 10s invoke a function as an example. The following log output using slf4j + log4j, unnecessary output can be changed to self System.out.println

Code

Directory idea is as follows:

1. Profiles quartz_timer.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
    <bean id="myQuartzTimer" class="com.ydfind.demo.springtimer.MyQuartzTimer"></bean>
    <bean id="myQuartzTimerJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject">
            <ref bean="myQuartzTimer"/>
        </property>
        <property name="targetMethod" value="doTask"/>
    </bean>
    <bean id="myQuartzTimerTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
        <property name="jobDetail" ref="myQuartzTimerJob"/>
        <!-- 确保quartz的版本在1.8.6及以前的，否则会报错；每10s跑一次-->
        <property name="cronExpression" value="0/10 * 0-23 * * ?"/>
    </bean>
    <bean class = "org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref local="myQuartzTimerTrigger" />
            </list>
        </property>
    </bean>
</beans>

2.log4j.xml log configuration

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "./log4j.dtd">
<log4j:configuration>
	<appender name="consoleAppender" class="org.apache.log4j.ConsoleAppender">
		<layout class="org.apache.log4j.PatternLayout">
			<param name="ConversionPattern" value="[%-d{yyyy-MM-dd HH:mm:ss.SSS}][%p][%t] %X{operationName} %X{userId} - %m%n" />
		</layout>
	</appender>
	<root>
		<appender-ref ref="consoleAppender" />
	</root>
</log4j:configuration>

4. Timer class MyQuartzTimer.java

package com.ydfind.demo.springtimer;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.text.SimpleDateFormat;
import java.util.Date;

public class MyQuartzTimer {
    private static Logger logger = LoggerFactory.getLogger(MyQuartzTimer.class);
    private static int count;
    public void doTask(){
        try{
            synchronized (this){
                count++;
            }
            logger.info("第" + count + "次执行！当前时间为：" + new SimpleDateFormat("yyyyMMdd HH:mm:ss:SSS").format(new Date()));
        }catch(Exception e){
            e.printStackTrace();
        }
    }
}

5. Start the timer class MyQuartzMainApp.java

package com.ydfind.demo.springtimer;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.support.FileSystemXmlApplicationContext;

public class MyQuartzMainApp {
    private static Logger logger = LoggerFactory.getLogger(MyQuartzMainApp.class);
    public static void main(String[] args){
        logger.info("将要启动定时器---------");
        try{
            new FileSystemXmlApplicationContext(ClassLoader.getSystemResource("quartz_timer.xml").getFile());
        }catch (Exception e){
            e.printStackTrace();
        }
        logger.info("将要结束定时器---------");
    }
}

run

The main function running MyQuartzMainApp classes, as follows:

[2019-03-20 13:24:40.022][DEBUG][org.springframework.scheduling.quartz.SchedulerFactoryBean#0_Worker-1]   - Calling execute on job DEFAULT.myQuartzTimerJob

10s once per run correctly.
