如何在spring中配置定时任务

Answer 1

1.Scheduler的配置
<bean id="myScheduler"
class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="myTriggersA"></ref>
<ref bean="myTriggersB"></ref>
</list>
</property>
<property name="autoStartup" value="true"></property>
</bean>

2.Trigger的配置
<bean id="myTriggersA"
class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
<property name="jobDetail" ref="myJobDetailA">
</property>
<property name="cronExpression">
<value>0/1 * * * * ?</value>
</property>
</bean>
3.JobDetail的配置
<bean id="myJobDetailA"
class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="myJobA">
</property>
<!-- 指定执行脚本的方法 -->
<property name="targetMethod" value="work"></property>
<property name="concurrent" value="false" />
<!-- 是否允许任务并发执行。当值为false时，表示必须等到前一个线程处理完毕后才再启一个新的线程 -->
</bean>
4.业务类的配置
<bean id="myJobA" class="com.quartz.MyJobA">
</bean>
5.业务类代码
import java.util.Date;

public class MyJobA {

public void work() {
System.out.println("date: " + new Date().getTime());
}
}
