Spring+Quartz实现定时任务的maven完整demo(idea)

例子说明

下面以每10s调用类中一个函数为例。下面的日志输出采用slf4j+log4j，不需要的可自行改为System.out.println输出

代码

idea目录如下所示：

1.配置文件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日志配置

<?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>

3.maven的pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <properties>

        </dependency>
        <!-- 定时任务框架Quartz的依赖-->

</project>

4.定时器类 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.启动定时器的类 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---------");
    }
}

运行

运行MyQuartzMainApp类的main函数，结果如下：

[2019-03-20 13:24:40.022][DEBUG][org.springframework.scheduling.quartz.SchedulerFactoryBean#0_Worker-1]   - Calling execute on job DEFAULT.myQuartzTimerJob
[2019-03-20 13:24:40.022][INFO][org.springframework.scheduling.quartz.SchedulerFactoryBean#0_Worker-1]   - 第1次执行！当前时间为：20190320 13:24:40:022

每10s运行一次，正确。
