Spring配置quartz調度任務

1、SPring Bean注入作業的兩種方式：

           方式一：@1、Spring使用JobDetailBean類，繼承QuartzJobBean，重寫
                       protected void executeInternal(JobExecutionContext context)方法

                       @2、  或實現Job接口，在execute方法中調用執行任務
                                                              
            方式二：Spring使用MethodInvokingJobDetailFactoryBean，普通Java類都可
2、方式一的實現：

  java 代碼

public class AlterJob extends QuartzJobBean{
    //業務實現
    public void work() {
        System.out.println("執行調度任務："+new Date());
    }

    @Override
    protected void executeInternal(JobExecutionContext arg0)
            throws JobExecutionException {
        this.work();
    }
//實現Job接口
//    public void execute(JobExecutionContext arg0) throws JobExecutionException {
//        this.work();
//    }
}

     applicationContext.xml的配置如下：

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:util="http://www.springframework.org/schema/util"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
                           http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
                           http://www.springframework.org/schema/util
                           http://www.springframework.org/schema/util/spring-util-2.0.xsd
                           ">
    <!-- 注入執行任務Bean -->
    <bean name="jobDetailBean"  class="org.springframework.scheduling.quartz.JobDetailBean" >
          <property name="jobClass"  value="com.boonya.quartz.job.AlterJob" />
          <property name="jobDataAsMap">
             <map>  
               <entry key="size" value="10"></entry>
             </map>  
         </property>  
         <property name="applicationContextJobDataKey" value="applicationContext"/>  
   </bean>
   <!-- 觸發器 -->
   <bean id="simpleTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean">  
       <property name="startDelay" value="20000"/>
       <property name="repeatInterval" value="60000"/>
       <property name="jobDetail" ref="jobDetailBean"/>
   </bean>  
   <bean id="cronTrigger"  class="org.springframework.scheduling.quartz.CronTriggerBean" >  
        <!-- 指向我們的任務 -->
        <property name="jobDetail" ref="jobDetailBean" />
        <!--  每分鐘10秒運行1次 -->
        <property name="cronExpression" value="0/10 * * * * ?" />
    </bean>
    <!-- 調度器   -->
    <!-- <bean id="startCornQuartzJob" lazy-init="false" class="org.springframework.scheduling.quartz.SchedulerFactoryBean" >       
         <property name="triggers">  
               <list>
                      觸發器列表    
                     <ref bean="cronTrigger" />   
               </list>          
         </property>            
         <property name="configLocation" value="classpath:quartz.properties" />
         <property name="autoStartup" value="true"/>  
         <property name="schedulerName" value="cronScheduler" />  
   </bean> -->
    <bean id="startSimpleQuartzJob" lazy-init="false" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">  
       <property name="triggers">  
           <list>  
               <ref bean="simpleTrigger"/>
               <ref bean="cronTrigger" />
           </list>  
       </property>  
       <property name="autoStartup" value="true"/>
       <property name="schedulerName" value="cronScheduler" />  
   </bean> 
</beans>

注意：這里任務啟動的時候startCornQuartzJob和startSimpleQuartzJob不能同時都開放，否則拋出異常。

3、方式2的實現：

java代碼

public class QuartzJob {
    
    public void work(){
        System.out.println("work執行調度任務："+new Date());
    }
}

applicationContext.xml/applicationContext-jobs.xml的配置

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>    
        <!-- 要調用的工作類 -->
        <bean id="quartzJob" class="com.boonya.quartz.job.QuartzJob"></bean>
        <!-- 定義調用對象和調用對象的方法 -->
        <bean id="jobTask" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
            <!-- 調用的類 -->
            <property name="targetObject">
                <ref bean="quartzJob"/>
            </property>
            <!-- 調用類中的方法 -->
            <property name="targetMethod">
                <value>work</value>
            </property>
        </bean>
        <!-- 定義觸發時間 -->
        <bean id="doTime" class="org.springframework.scheduling.quartz.CronTriggerBean">
            <property name="jobDetail">
                <ref bean="jobTask"/>
            </property>
            <!-- cron表達式 -->
            <property name="cronExpression">
                <value>10,15,20,25,30,35,40,45,50,55 * * * * ?</value>
            </property>
        </bean>
        <!-- 總管理類 如果將lazy-init='false'那么容器啟動就會執行調度程序  -->
        <bean id="startQuartz" lazy-init="false" autowire="no"         class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
            <property name="triggers">
                <list>
                    <ref bean="doTime"/>
                </list>
            </property>
        </bean>
</beans>

注：方式2的配置可以作為外部文件導入到applicationContext.xml中去。

測試方法二:

public static void main(String[] args)    {
        System.out.println("----------Test start.-------\n");
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-jobs.xml");
        //如果配置文件中將startQuertz bean的lazy-init設置為false 則不用實例化
        context.getBean("startQuartz");
  }

4、web.xml配置{跟以前沒有區別}

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
         xmlns="http://java.sun.com/xml/ns/j2ee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

   <!-- 指定spring配置文件位置 -->
  <context-param>    
   <param-name>contextConfigLocation</param-name>
     <!--加載多個spring配置文件 -->  
        <param-value>classpath:applicationContext*.xml</param-value>
  </context-param>
  <!-- 定義SPRING監聽器，加載spring -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
  </listener>
  <!-- 字符過濾器 -->
  <filter>   
    <filter-name>SetCharacterEncoding</filter-name>
         <filter-class>   org.springframework.web.filter.CharacterEncodingFilter    </filter-class>
         <init-param>     
             <param-name>encoding</param-name>  
             <param-value>UTF-8</param-value>   
          </init-param>     
          <init-param>  
               <param-name>forceEncoding</param-name>   
               <param-value>true</param-value>
          </init-param>  
  </filter>  
  <filter-mapping>   
    <filter-name>SetCharacterEncoding</filter-name>
     <url-pattern>/*</url-pattern>  
  </filter-mapping>
</web-app>

5、需要的Jar包：spring.jar,quartz.jar，若涉及持久化操作需要jpa.jar....等等，根據自己項目的需要添加。

   搞了一天終于出來了，記于此處！

6、附上corn語法及示例

corn=[秒 分 時  日 月 周  年]
