Spring和quartz整合的入门使用教程

Quartz的maven依赖

        <!-- quartz 的jar -->
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz</artifactId>
            <version>2.2.1</version>
        </dependency>
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz-jobs</artifactId>
            <version>2.2.1</version>
        </dependency>

方法一

基于特定基类 编写任务类，该类需要继承自QuartzJobBean

package com.sys.task;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.scheduling.quartz.QuartzJobBean;

/**
 * @Author:jimisun
 * @Description:
 * @Date:Created in 9:36 2018/8/1
 * @Modified By:
 */
public class QuartzTestJob extends QuartzJobBean {

    public QuartzTestJob() {
        super();
    }

    private static final Logger logger = LoggerFactory.getLogger(QuartzTestJob.class);
    private Integer timeout;

    //调度工厂实例化后，经过timeout时间开始执行调度
    public void setTimeout(Integer timeout) {
        this.timeout = timeout;
    }

    @Override
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
        logger.info("定时任务1进行中.......");
    }

}

Spring中配置Quartz

  <!--开源作业调度框架
    org.springframework.scheduling.quartz.JobDetailBean有两个属性.

　　　　jobClass属性即我们在java代码中定义的任务类.

　　　　jobDataAsMap属性即该任务类中需要注入的属性值.-->
    <bean name="quartzTestJob1" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
        <property name="jobClass" value="com.sys.task.QuartzTestJob"/>
        <property name="jobDataAsMap">
            <map>
                <entry key="timeout" value="0"/>
            </map>
        </property>
    </bean>
    <!--Cron表达式触发器
    Quartz的作业触发器有两种(两种任选其一就行)

　　　　org.springframework.scheduling.quartz.SimpleTriggerFactoryBean:只支持按照一定频度调用任务，如每隔30分钟运行一次.

　　　　org.springframework.scheduling.quartz.CronTriggerFactoryBean:支持到指定时间运行一次，如每天12:00运行一次等-->
    <bean id="cronTrigger1" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail" ref="quartzTestJob1"/>
        <property name="cronExpression" value="0/5 * * * * ?"/>
    </bean>
        <!--按照一定频率的触发器-->
 <!--   <bean id="cronTrigger1" class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">
        <property name="jobDetail" ref="quartzTestJob1"/>
        <property name="startDelay" value="0"/>
        <property name="repeatInterval" value="2000"/>
    </bean>-->
    <!--配置调度工厂-->
    <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <!--<ref bean="simpleTrigger"/>-->
                <ref bean="cronTrigger1"/>
            </list>
        </property>
    </bean>

执行结果

DEBUG [org.springframework.scheduling.quartz.SchedulerFactoryBean#0_Worker-3] - Calling execute on job DEFAULT.quartzTestJob1
DEBUG [org.springframework.scheduling.quartz.SchedulerFactoryBean#0_QuartzSchedulerThread] - batch acquisition of 1 triggers
 INFO [org.springframework.scheduling.quartz.SchedulerFactoryBean#0_Worker-3] - 定时任务1进行中.......

方法二

不基于特定的基类 编写普通的方法类

package com.sys.task;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

/**
 * @Author:jimisun
 * @Description:
 * @Date:Created in 9:36 2018/8/1
 * @Modified By:
 */
public class QuartzTestJob3 {

    private static final Logger logger = LoggerFactory.getLogger(QuartzTestJob3.class);

    public void executeJob() {
        logger.info("定时任务3进行中.......");
    }
}

在spring配置文件中配置作业类MethodInvokingJobDetailFactoryBean、作业调度的触发方式（触发器）、调度工厂

  <!--MethodInvokingJobDetailFactoryBean，有两个关键属性：targetObject指定任务类.targetMethod指定运行的方法.-->
    <bean name="quartzTestJob3" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject">
            <bean class="com.sys.task.QuartzTestJob3"/>
        </property>
        <property name="targetMethod" value="executeJob"/>
        <!--作业不并发调度-->
        <property name="concurrent" value="false"/>
    </bean>
    <!--Cron表达式触发器-->
    <bean id="cronTrigger1" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail" ref="quartzTestJob3"/>
        <property name="cronExpression" value="0/5 * * * * ?"/>
    </bean>
    <!--配置调度工厂-->
    <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <!--<ref bean="simpleTrigger"/>-->
                <ref bean="cronTrigger1"/>
            </list>
        </property>
    </bean>

执行结果

DEBUG [org.springframework.scheduling.quartz.SchedulerFactoryBean#0_Worker-6] - Calling execute on job DEFAULT.quartzTestJob3
 INFO [org.springframework.scheduling.quartz.SchedulerFactoryBean#0_Worker-6] - 定时任务3进行中.......
DEBUG [org.springframework.scheduling.quartz.SchedulerFactoryBean#0_QuartzSchedulerThread] - batch acquisition of 1 triggers
