spring4.2.5实现调度任务的几种方式

目前spring的最新版本是4.2.5，通过对spring scheduling的学习，总结有几种可以实现调度任务的方式

1、注解

2、Task命名空间

3、使用Quartz调度

下面分别介绍实现方式

首先引入相关jar包，pom.xml中配置：

<dependency>          <groupId>javax.servlet</groupId>          <artifactId>servlet-api</artifactId>          <version>2.3</version>          <scope>compile</scope>      </dependency>      <dependency>          <groupId>org.springframework</groupId>          <artifactId>spring-web</artifactId>          <version>4.2.5.RELEASE</version>      </dependency>      <dependency>          <groupId>org.springframework</groupId>          <artifactId>spring-context</artifactId>          <version>4.2.5.RELEASE</version>      </dependency>      <dependency>          <groupId>org.springframework</groupId>          <artifactId>spring-context-support</artifactId>          <version>4.2.5.RELEASE</version>      </dependency>      <dependency>          <groupId>org.springframework</groupId>          <artifactId>spring-tx</artifactId>          <version>4.2.5.RELEASE</version>      </dependency>      <dependency>          <groupId>org.quartz-scheduler</groupId>          <artifactId>quartz</artifactId>          <version>2.2.2</version>      </dependency>

web.xml中配置加载spring：

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" ><web-app>  <display-name>Archetype Created Web Application</display-name>    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>    <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:spring-config.xml</param-value>    </context-param></web-app>

1、使用注解的方式开始调度任务

配置java类

<pre style="background-color:#2b2b2b;color:#a9b7c6;font-family:'宋体';font-size:11.3pt;"><span style="color:#cc7832;">package </span>test.spring.scheduling.annotation<span style="color:#cc7832;">;</span><span style="color:#cc7832;"></span><span style="color:#cc7832;">import </span><span style="color:#bbb529;">org.springframework.context.annotation.Configuration</span><span style="color:#cc7832;">;</span><span style="color:#cc7832;">import </span><span style="color:#bbb529;">org.springframework.scheduling.annotation.EnableScheduling</span><span style="color:#cc7832;">;</span><span style="color:#cc7832;">import </span><span style="color:#bbb529;">org.springframework.scheduling.annotation.Scheduled</span><span style="color:#cc7832;">;</span><span style="color:#cc7832;"></span><span style="color:#cc7832;">import </span>java.util.Date<span style="color:#cc7832;">;</span><span style="color:#629755;font-style:italic;"></span><span style="color:#bbb529;">@Configuration</span><span style="color:#bbb529;">@EnableScheduling</span><span style="color:#cc7832;">public class </span>AnnotationScheduleService {    <span style="color:#bbb529;">@Scheduled</span>(<span style="color:#d0d0ff;">cron </span>= <span style="color:#6a8759;">"0/5 * * * * ?"</span>)    <span style="color:#cc7832;">public void </span><span style="color:#ffc66d;">test</span>(){        System.<span style="color:#9876aa;font-style:italic;">out</span>.println(<span style="color:#cc7832;">new </span>Date())<span style="color:#cc7832;">;</span><span style="color:#cc7832;">    </span>}}

配置spring.xml

<?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:task="http://www.springframework.org/schema/task"       xmlns:context="http://www.springframework.org/schema/context"       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd       http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">    <context:component-scan base-package="test.spring.scheduling.annotation"/>    <task:scheduler id="myAnnotationScheduler" pool-size="10"/>    <task:annotation-driven scheduler="myAnnotationScheduler"/></beans>

2、使用task命名空间运行schedule

java类

package test.spring.scheduling.tasknamespace;import java.util.Date;/** * Created by yuan on 2016/3/12. */public class TaskNamespaceScheduleService {    public void test(){        System.out.println("TaskNamespaceScheduleService "+new Date());    }}

spring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:task="http://www.springframework.org/schema/task"       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd       http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd">    <bean id="taskNamespaceScheduleService" class="test.spring.scheduling.tasknamespace.TaskNamespaceScheduleService"/>    <task:scheduled-tasks>        <task:scheduled ref="taskNamespaceScheduleService" method="test" cron="*/5 * * * * ?"/>    </task:scheduled-tasks></beans>

或者：

<?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:task="http://www.springframework.org/schema/task"       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd       http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd">    <bean id="taskNamespaceScheduleService" class="test.spring.scheduling.tasknamespace.TaskNamespaceScheduleService"/>    <task:scheduler id="myTaskNamespaceScheduler" pool-size="10"/>    <task:scheduled-tasks scheduler="myTaskNamespaceScheduler">        <task:scheduled ref="taskNamespaceScheduleService" method="test" cron="*/5 * * * * ?"/>    </task:scheduled-tasks></beans>

3、使用Quartz调度schedule

分别使用JobDetailFactoryBean和MethodInvokingJobDetailFactoryBean配置调度任务

package test.spring.scheduling.quartz;import org.quartz.JobExecutionContext;import org.quartz.JobExecutionException;import org.springframework.scheduling.quartz.QuartzJobBean;import java.util.Date;/** * Created by yuan on 2016/3/12. */public class QuartzOne extends QuartzJobBean {    /**     * Execute the actual job. The job data map will already have been     * applied as bean property values by execute. The contract is     * exactly the same as for the standard Quartz execute method.     *     * @param context     * @see #execute     */    @Override    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {        System.out.println("QuartzOne "+new Date());    }}

package test.spring.scheduling.quartz;import java.util.Date;/** * Created by yuan on 2016/3/12. */public class QuartzTwo {    public void test(){        System.out.println("QuartzTwo "+new Date());    }}

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       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">    <!-- 使用JobDetailFactoryBean -->    <bean name="quartzOneJob" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">        <property name="jobClass" value="test.spring.scheduling.quartz.QuartzOne"/>    </bean>    <!-- 使用MethodInvokingJobDetailFactoryBean -->    <bean id="quartzTwoBean" class="test.spring.scheduling.quartz.QuartzTwo"/>    <bean name="quartzTwoJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">        <property name="targetObject" ref="quartzTwoBean"/>        <property name="targetMethod" value="test"/>    </bean>    <!-- 配置trigger -->    <bean id="simpleTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">        <!-- see the example of method invoking job above -->        <property name="jobDetail" ref="quartzOneJob"/>        <!-- 10 seconds -->        <property name="startDelay" value="10000"/>        <!-- repeat every 11 seconds -->        <property name="repeatInterval" value="11000"/>    </bean>    <bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">        <property name="jobDetail" ref="quartzTwoJob"/>        <!-- 每5秒执行一次 -->        <property name="cronExpression" value="0/5 * * * * ?"/>    </bean>    <!-- 配置SchedulerFactoryBean -->    <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">        <property name="triggers">            <list>                <ref bean="cronTrigger"/>                <ref bean="simpleTrigger"/>            </list>        </property>    </bean></beans>
