Spring中使用quartz执行定时任务的两种方式

一, 继承spring封装Quartz类(org.springframework.scheduling.quartz.QuartzJobBean)方式，其实QuartzJobBean类实现了quartz的Job接口  
(直接使用quartz时，每一个自定义的定时任务job类都要实现job接口)  
spring-mvc-quartz2.xml:  
<bean id="job2Trigger" class="org.springframework.scheduling.quartz.CronTriggerBean">    
    <property name="jobDetail">    
        <bean class="org.springframework.scheduling.quartz.JobDetailBean">    
            <property name="jobClass" value="com.yueguang.schedule.Job2"/>    
            <property name="jobDataAsMap">        
                <map><entry key="job2Service" value-ref="job2Service"/></map>    
            </property>   
        </bean>    
    </property>    
        
    <property name="cronExpression" value="0/1 \* \* \* \* ?"/>    
</bean>  
  
<bean id="schedulerFactory" lazy-init="false" autowire="no" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">  
    <property name="triggers">  
        <list>  
        <ref bean="job2Trigger" />  
    </list>  
    </property>  
</bean>      
<bean id="job2Service" class="....">  
</bean>  
  
package com.yueguang.schedule;  
import org.quartz.JobExecutionContext;  
import org.quartz.JobExecutionException;  
import org.springframework.scheduling.quartz.QuartzJobBean;  
  
public class Job2 extends QuartzJobBean \{  
    private Job2Service job2Service;  
  
  
    @Override  
    protected void executeInternal(JobExecutionContext jobexecutioncontext)  
            throws JobExecutionException \{  
        job2Service.test();  
    \}  
  
  
    public void setJob2Service(Job2Service job2Service) \{  
        this.job2Service = job2Service;  
    \}  
\}

二,利用spring MethodInvokingJobDetailFactoryBean类,不需要继承.  
spring-mvc-quartz1.xml  
  
    <bean id="job1"  
        class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">  
        <property name="targetObject" ref="job1" />  
        <property name="targetMethod" value="execute" />  
        <property name="concurrent" value="true" />      
    </bean>  
      
    <bean id="job1Trigger" class="org.springframework.scheduling.quartz.CronTriggerBean">  
        <property name="jobDetail" ref="job1" />  
        <property name="cronExpression" value="0/1 \* \* \* \* ?" />  
    </bean>  
      
      
    <bean id="schedulerFactory" lazy-init="false" autowire="no" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">  
        <property name="triggers">  
            <list>  
                <ref bean="job1Trigger" />  
                  
            </list>  
        </property>  
    </bean>

public class Job1 \{   
    private Job1Service job1Service;  
  
   public void execute() \{

system.out.println("---test----");

\}  
\}

注:

1、在第一种方式中,不能在jobbean中直接以注解的方式注入spring bean组件,必须在jobDetail的属性jobDataAsMap中配置要注入的bean组件,同时需要在该jobbean中写好对应的setter.

2、在实际开发中，第二种方式很方便，特别是在使用注解的情况下。
