Quartz總結（三）：動態修改定時器一

package com.mc.bsframe.job;

import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.TriggerKey;
import org.quartz.impl.triggers.SimpleTriggerImpl;
import org.springframework.beans.factory.annotation.Autowired;

import com.mc.bsframe.service.TestService;
import com.mc.bsframe.util.TimeUtils;

public class TestJob {

    @Autowired
    private TestService testSevice;
    
    public void doSomething() {
        testSevice.sayHi();
        System.err.println("****:" + TimeUtils.getCurrentTime());
    }

    private Scheduler scheduler;

    public Scheduler getScheduler() {
        return scheduler;
    }

    public void setScheduler(Scheduler scheduler) {
        this.scheduler = scheduler;
    }

    public void restJob(long time) {
        TriggerKey triggerKey=new TriggerKey("testTrigger", Scheduler.DEFAULT_GROUP);
        SimpleTriggerImpl simpleTrigger=null;
        try {
            simpleTrigger= (SimpleTriggerImpl) scheduler.getTrigger(triggerKey);
        } catch (SchedulerException e) {
            e.printStackTrace();
        }
        simpleTrigger.setRepeatInterval(time);
        
        try {
            scheduler.rescheduleJob(triggerKey,simpleTrigger);
        } catch (SchedulerException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

代碼如上：在任務類中注入Scheduler，然后添加restJob方法。

配置文件如下：

<?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.xsd">

    <!-- 要執行任務的任務類。 -->
    <bean id="testQuartz" class="com.mc.bsframe.job.TestJob">
        <property name="scheduler" ref="schedulerFactoryBean"></property>
    </bean>

    <!-- 將需要執行的定時任務注入JOB中。 -->
    <bean id="testJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject" ref="testQuartz"></property>
        <!-- 任務類中需要執行的方法 -->
        <property name="targetMethod" value="doSomething"></property>
        <!-- 上一次未執行完成的，要等待有再執行。 -->
        <property name="concurrent" value="false"></property>
    </bean>

    <!-- 基本的定時器，會綁定具體的任務。 -->
    <bean id="testTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">
        <property name="jobDetail" ref="testJob"></property>
        <property name="startDelay" value="3000"></property>
        <property name="repeatInterval" value="2000"></property>
    </bean>

    <bean id="schedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="testTrigger"></ref>
            </list>
        </property>
    </bean>
</beans>

使用方法：

    @Autowired
    @Qualifier(value="testQuartz")
    private TestJob job;
    
    @RequestMapping("/job")
    public void job(Long time){
        job.restJob(time);
    }
