配置quartz啟動時就執行一次

1. 新增maven依賴。pom.xml 中新增jar檔案

<!-- 作業任務排程機制 -->
<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.任務交給spring管理。web.xml 檔案中引入任務排程的配置檔案
  <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath*:/config/applicationContext-shiro.xml,
            classpath*:/config/applicationContext-quartz.xml
        
</param-value> </context-param>

3. 配置任務排程。編寫 applicationContext-quartz.xml 配置檔案
<?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"> <!-- 定時器工作排程的bean --> <bean id="myJob" class="com.xx.xxxx.ws.quarter.MyJob" /> <!-- job的配置開始 --> <bean id="myJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"> <property name="targetObject"> <ref bean="myJob" /> </property> <property name="targetMethod"> <value>work</value> </property> </bean> <!-- 排程的配置開始 --> <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> <!-- 啟動觸發器的配置開始 --> <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. 編寫任務類。編寫定時器類 <bean id="myJob" class="com.xx.xxxx.ws.quarter.MyJob" />
public class MyJob {
    public void work()
    {
         System.out.println("work done----------");  
    }
}

4. 如何配置quartz(隨spring啟動)執行一次
 <!-- 配置專案啟動後任務就執行一次 -->  
    <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>  

觸發器當中新增配置任務

<!-- 啟動觸發器的配置開始 -->
    <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>
