Spring与Quartz结合

1.实例

依赖

<dependency>
<groupId>commons-collections</groupId>
<artifactId>commons-collections</artifactId>
<version>3.2.1</version>
</dependency>
<dependency>
<groupId>org.opensymphony.quartz</groupId>
<artifactId>quartz-all</artifactId>
<version>1.6.1</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>3.1.1.RELEASE</version>
</dependency>

当然还需要spring的核心依赖

（1）具体执行任务的类

不用实现任何接口

public class MyJob
{
Logger logger = LoggerFactory.getLogger(MyJob.class);

public void execute() throws JobExecutionException {
logger.info("{} task is start", new Date());
}

}

（2）spring配置文件中定义执行任务的类，和需要执行的方法

<!-- 定义目标bean和bean中的方法 -->
<!-- =====================日常任务job========================== -->
<bean id="myJob" class="com.mycompany.quartz.MyJob">
</bean>
<bean id="myJobMethod" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject">
<ref bean="myJob"/>
</property>
<property name="targetMethod">  <!-- 要执行的方法名称 -->
<value>execute</value>
</property>
</bean>

（2）定义trigger

<!-- ======================== 调度触发器 ======================== -->
<bean id="myTriggerBean" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail" ref="myJobMethod"></property>
<property name="cronExpression" value="0/5 * * * * ?"></property>
</bean>

（3）定义调度工厂

<!-- ======================== 调度工厂 ======================== -->
<bean id="SpringJobSchedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="myTriggerBean"/>
</list>
</property>
</bean>

2.注意

（1）spring的<beans>中一定不能定义default-autowire="byName"

（2）<beans>不能设置default-lazy-int="true"，否则定时任务不会触发
