Quartz (二) 和Spring整合

先给个场景：每五分钟扫描并关闭7天未付款的订单

1.quartz pom.xml依赖

 <dependencies>
      <dependency>
          <groupId>org.springframework</groupId>
          <artifactId>spring-context-support</artifactId>
          <version>4.0.6.RELEASE</version>
      </dependency>
      <dependency>
          <groupId>org.slf4j</groupId>
          <artifactId>slf4j-log4j12</artifactId>
          <version>1.7.7</version>
      </dependency>
      <dependency>
          <groupId>org.quartz-scheduler</groupId>
          <artifactId>quartz</artifactId>
          <version>2.2.1</version>
      </dependency>
      <dependency>
          <groupId>org.springframework</groupId>
          <artifactId>spring-tx</artifactId>
          <version>4.0.6.RELEASE</version>
      </dependency>
  </dependencies>

 2.spring.xml 配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
        
    <!-- 定义任务 -->
    <bean id="payment" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
        <!-- 指定具体的job类 -->
        <property name="jobClass" value="com.kawa.order.job.payOrderJob"></property>
        <!-- 指定job名称 -->
        <property name="name" value="payOrder"></property>
        <!-- 指定job的分组 -->
        <property name="group" value="Order"></property>
        <!-- 必须设置为true,如果为false,当没活动的触发器与之关联时会在调度器中删除该任务-->
        <property name="durability" value="true"></property>
        <!-- 指定spring容器的key,如果不设定在jobmap中是获取不到spring容器的 -->
        <property name="applicationContextJobDataKey" value="applicationContext"></property>
    </bean>
    
    <!-- 定义触发器 -->
    <bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail" ref="payment"></property>
        <!-- 每一分钟执行一次，清理无效订单 -->
        <property name="cronExpression" value="0 0/1 * * * ?"></property>
    </bean>

    <!-- 定义调度器 -->
    <bean id="" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="cronTrigger"/>
            </list>
        </property>
    </bean>
</beans>

 3.java 代码package com.kawa.order.job;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.context.ApplicationContext;
import org.springframework.scheduling.quartz.QuartzJobBean;

import com.taotao.order.service.OrderService;

public class payOrderJob extends QuartzJobBean{

    @Override
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
        //获取spring容器
        ApplicationContext applicationContext = (ApplicationContext) context.getJobDetail().getJobDataMap().get("applicationContext");
        //获取OrderService实例,clearOrder为执行方法名
        //new DateTime().minusDays(7).toDate()为当前时间前7天
        //clearOrder方法的逻辑就不写了...
        applicationContext.getBean(OrderService.class).clearOrder(new DateTime().minusDays(7).toDate());
    }

}
