Quartz 定时器任务调度配置(以及如何配置quartz启动执行一次)

1. 添加maven依赖。pom.xml 中添加jar文件

<!-- 作业任务调度机制 -->
<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>

2.任务交给spring管理。web.xml 文件中引入任务调度的配置文件

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath*:/config/applicationContext-shiro.xml,
            classpath*:/config/applicationContext-quartz.xml
        </param-value>
    </context-param>

3. 配置任务调度。编写 applicationContext-quartz.xml 配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:cache="http://www.springframework.org/schema/cache"
    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
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/cache
        http://www.springframework.org/schema/cache/spring-cache.xsd">
    <!-- 定时器工作调度的bean -->
    <bean id="myJob" class="com.xx.xxxx.ws.quarter.MyJob" />
    <!-- job的配置开始 -->
    <bean id="myJobDetail"
        class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject">
            <ref bean="myJob" />
        </property>
        <property name="targetMethod">
            <value>work</value>
        </property>
    </bean>
    <!-- 调度的配置开始 -->
    <bean id="crontestJobTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail">
            <ref bean="myJobDetail" />
        </property>
        <property name="cronExpression">
            <value>0/10 * * * * ?</value>
        </property>
    </bean>
    <!-- 启动触发器的配置开始 -->
    <bean name="startQuertz" lazy-init="false" autowire="no"
        class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="crontestJobTrigger" />
            </list>
        </property>
    </bean>
</beans>

4. 编写任务类。编写定时器类 <bean id="myJob" class="com.xx.xxxx.ws.quarter.MyJob" />

package com.xx.xxxx.ws.quarter;
public class MyJob {
    public void work()
    {
         System.out.println("work done----------");
    }
}

4. 如何配置quartz(随spring启动)执行一次

    <!-- 配置项目启动后任务就执行一次 -->
    <bean id="rsh_simpleTrigger1" class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">
        <property name="jobDetail" ref="myJobDetail" />
        <property name="startDelay" value="500" />
        <property name="repeatInterval" value="0" />
        <property name="repeatCount" value="0" />
    </bean>  

　　触发器当中添加配置任务

    <!-- 启动触发器的配置开始 -->
    <bean name="startQuertz" lazy-init="false" autowire="no"
        class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="rsh_simpleTrigger1" />
                <ref bean="crontestJobTrigger" />
            </list>
        </property>
    </bean>
