• spring通过配置xml文件集成quartz定时器

    概述

    Spring为创建Quartzde Scheduler、Trigger和JobDetail提供了方便的FactoryBean类，以便能够在Spring容器中享受注入的好处。

    此外，Spring还通了一些便利的工具类，用于直接将Spring中的Bean包装成合法的任务。

    Spring进一步降低了使用Quartz的难度，能够以更加Spring风格的方式使用Quartz，主要体现在如下两点

    • 为Quartz的重要组件提供更具Bean风格的扩展类

    • 提供创建Scheduler的BeanFactory类，方便在Spring环境下创建对应的组件对象，并结合Spring容器生命周期执行启动和停止的动作

    Maven依赖

    主要的两个依赖如下:

    <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context-support</artifactId>
            <version>${spring.version}</version>
</dependency>

<dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz</artifactId>
            <version>2.2.3</version> 
</dependency>

    spring-context-support包主要是Spring集成了很多有用的第三方库，我们在使用第三方的东西的时候一般都需要引入该依赖。

    步骤

    Spring通过xml的方式集成Quartz,主要有两种方式

    1. JobDteail通过JobDetailBean实现

    2. JobDteail通过MethodInvokeJobDetailFactoryBean实现(推荐)

    1 创建JobDteail

    Spring通过扩展JobDetail提供了一个更具Bean风格的JobDetailFactoryBean,此外Spring还提供了了一个 MethodInvokingJobDetailFactoryBean，通过这个FactoryBean可以将Spring容器中的Bean的方法包装成Quartz任务，这样我们就不必为Job创建对应的类。

    案例中会分别讲述两种实现方式的区别

    2 创建Trigger

    Quartz中另外一个重要的组件就是Trigger，Spring按照相似的思路分别为SimpleTrigger和CronTrigger提供了更具Bean风格的CronTriggerFactoryBean和SimpleTriggerFactoryBean扩展类。

    3 创建Scheduler

    Quartz的SchedulerFactory是标准的工厂类，不太适合在Spring中使用。 此外为了保证Scheduler能够感知Spring容器的生命周期，在Spring容器启动后，Scheduler自动开始工作，而在Spring容器关闭前，自动关闭Scheduler。为此Spring提供了SchedulerFactoryBean.

    示例-MethodInvokingJobDetailFactoryBean

    这里写图片描述

    因为下面的案例中我们使用MethodInvokingJobDetailFactoryBean，所以下面的这个Job无需继承任何类或者实现任何接口

    模拟业务类

    配置成一个普通的java类即可

    package com.xgj.quartz.quartzWithSpring.xml;


/**
 * 
 * 
 * @ClassName: MyJob
 * 
 * @Description: 不用继承Quartz的Job接口
 * 
 * @author: Mr.Yang
 * 
 * @date: 2017年11月10日 下午10:17:26
 */
public class MyJob {

    public void execute() {
        System.out.println("Quartz Spring XML 配置 - MyJob");
    }

}

    Spring集成Quartz的配置文件

    <?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">

    <!-- 配置Job类 -->
    <bean id="myJob" class="com.xgj.quartz.quartzWithSpring.xml.MyJob"></bean>

    <!-- 配置JobDetail -->
    <bean id="springQtzJobMethod" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <!-- 执行目标job -->
        <property name="targetObject" ref="myJob"></property>

        <!-- 要执行的方法 -->
        <property name="targetMethod" value="execute"></property>
    </bean>

    <!-- 配置tirgger触发器 -->
    <bean id="cronTriggerFactoryBean" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <!-- jobDetail -->
        <property name="jobDetail" ref="springQtzJobMethod"></property>

        <!-- cron表达式，执行时间  每5秒执行一次 -->
        <property name="cronExpression" value="0/5 * * * * ?"></property>
    </bean>

    <!-- 配置调度工厂 -->
    <bean id="springJobSchedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="cronTriggerFactoryBean"></ref>
            </list>
        </property>

    </bean>
</beans>

    除了使用CronTrigger也可以使用SimpleTrigger配置，示例代码如下

    <bean id="simpleTrigger"  class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">
    <!--配置具体要执行的jobDetail-->
    <property name="jobDetail" ref="simpleJobDetail" />
    <!--初始延迟时间 1s-->
    <property name="startDelay" value="1000" />
    <!--间隔执行时间每2s执行一次-->
    <property name="repeatInterval" value="2000" />
</bean>

    测试类

    package com.xgj.quartz.quartzWithSpring.xml;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class SpringQuartzXmlTest {

    public static void main(String[] args) {
        // 启动Spring 容器
        ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext(
                        "classpath:com/xgj/quartz/quartzWithSpring/xml/application.xml");
        System.out.println("initContext successfully");
    }
}

    在调度器中，有一个lazy-init参数,如果lazy-init=’false’,则容器启动时就会执行调度程序;如果lazy-init=’true’,则需要实例化该bean才能执行调度程序；

    <bean id="springJobSchedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean" lazy-init="true">

    运行结果
