Spring4 多种定时器详解

转载自：http://blog.csdn.net/u010994277/article/details/43835945

注意：spring4已经没有org.springframework.scheduling.timer.ScheduledTimerTask这个类，所以不能用spring3以前的timerTask方法。现spring4定时器方法推荐一下两只方法：（需要单独导入quartz包，只能是1.8.+）

spring代码如下：

 <span style="white-space:pre">    </span><!-- 方式1 -->
     <bean name="exampleJob" class="org.springframework.scheduling.quartz.JobDetailBean">
         <property name="jobClass" value="com.spring.task.TaskOne" />
         <property name="jobDataAsMap">
             <map>
                 <entry key="timeout" value="5" />
             </map>
         </property>
     </bean>
     <bean id="cronTrigger"
         class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
         <property name="jobDetail" ref="exampleJob" />
         <!-- run every morning at 6 AM -->
         <!-- <property name="cronExpression" value="0 0 6 * * ?" /> -->
         <!-- <property name="cronExpression" value="0 0/1 * * * ?" /> --> <!-- 每分钟 -->
         <property name="cronExpression" value="0/2 * * * * ?" /> <!-- 每秒 -->
     </bean>

     <!-- 方式2 -->
     <bean id="exampleBusinessObject" class="com.spring.task.TaskTwo" />
     <bean id="jobDetail"
         class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
         <property name="targetObject" ref="exampleBusinessObject" />
         <property name="targetMethod" value="doIt" />
         <property name="concurrent" value="false" />
     </bean>
     <bean id="simpleTrigger"
         class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">
         <!-- see the example of method invoking job above -->
         <property name="jobDetail" ref="jobDetail" />
         <!-- 10 seconds -->
         <property name="startDelay" value="5000" />
         <!-- repeat every 50 seconds -->
         <property name="repeatInterval" value="3000" />
     </bean>

     <!-- 总调度用于启动Spring定时器 -->
     <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
         <property name="triggers">
             <list>
                 <ref bean="cronTrigger" />
                 <ref bean="simpleTrigger" />
             </list>
         </property>
     </bean>

JAVA代码如下(方式1)：

 package com.spring.task;

 import org.apache.log4j.Logger;
 import org.quartz.JobExecutionContext;
 import org.quartz.JobExecutionException;
 import org.springframework.scheduling.quartz.QuartzJobBean;

 public class TaskOne extends QuartzJobBean {

     protected static final Logger log=Logger.getLogger(TaskOne.class);

     private int timeout;

     /**
      * Setter called after the ExampleJob is instantiated
      * with the value from the JobDetailBean (5)
      */
     public void setTimeout(int timeout) {
         this.timeout = timeout;
     }

     @Override
     protected void executeInternal(JobExecutionContext arg0)
             throws JobExecutionException {
         // TODO Auto-generated method stub
         log.info("-----定时任务执行-----");

     }


 }

JAVA代码如下(方式2 )：

 package com.spring.task;

 import org.apache.log4j.Logger;

 public class TaskTwo {
     protected static final Logger log=Logger.getLogger(TaskTwo.class);

     public void doIt(){
         log.info("-----定时任务执行-----");

     }
 }
