spirng定时任务的两种配置：注解和xml

一 使用注解Task

1、在applicationContext.xml中配置

<?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:context="http://www.springframework.org/schema/context"
    xmlns:task="http://www.springframework.org/schema/task"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-3.2.xsd
        http://www.springframework.org/schema/task
        http://www.springframework.org/schema/task/spring-task-3.2.xsd    ">
    <!-- 扫描路径-->
    <context:component-scan base-package="com.mediaforce.news.api.quartz" />
    <task:executor id="executor" pool-size="1" />
    <task:scheduler id="scheduler" pool-size="1" />
    <task:annotation-driven executor="executor" scheduler="scheduler" />
</beans>

2、在任务类中使用注解

import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;  

@Component(“taskJob”)
public class TaskJob {
    @Scheduled(cron = "0 0 3 * * ?")
    public void job1() {
        System.out.println(“任务进行中。。。”);
    }
}  

二、使用xml配置quarz

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx"
    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-3.0.xsd
   http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd ">

    <!-- 微信抓取 -->
    <bean id="weixinJobDetail"
        class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject">
            <ref bean="taskJob" />   //目标类
        </property>
        <property name="targetMethod">
            <value>weixin</value>    //目标执行方法
        </property>
    </bean>

    <!-- 微信抓取，1分钟一次 -->
    <bean id="cronWeixinJobDetail" class="org.springframework.scheduling.quartz.CronTriggerBean">
        <property name="jobDetail">
            <ref bean="weixinJobDetail" />
        </property>
        <property name="cronExpression">
            <value>0 0/1 * * * ?</value>
        </property>
    </bean>

    <!-- 执行定时任务-->
    <bean id="zz" autowire="no"
        class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="cronWeixinJobDetail" />
            </list>
        </property>
    </bean>

</beans>
