spring 定时任务

1. code ,定时执行的方法

package com.thunisoft.webservice.service;


import java.util.HashMap;
import java.util.Map;
import java.util.Map.Entry;
import org.apache.log4j.Logger;
import org.springframework.context.ApplicationContext;

/**
* 将客户端请求的查询结果返回
* @return
*/
public  String ajNum(String queryParam){

}
public void setFyimpl(Ify2000 fyimpl) {

}

}

2. applicationContext.xml 配置文件

<!-- 实现类 -->
<bean id = "fy2000" class="com.thunisoft.webservice.daoImpl.Fy2000Impl">
<property name="dataSource">
<ref bean="dataSource"></ref>
</property> 
</bean>
<!-- 服务类 -->
<bean id = "fy2000service" class="com.thunisoft.webservice.service.Fy2000Service">
<property name="fyimpl">
<ref bean="fy2000"></ref>
</property>

<property name ="queryParam">

<value>${service.queryParam}</value>
</bean>

<!-- 定时任务 service-->
<bean id ="fy2000ServiceTask" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="fy2000service"></property>

<!--根据spring定时任务规范,定时执行方法应为无参无返回值方法！ -->

<property name="targetMethod" value="backFyajxx"></property>
</bean>
<bean id ="fy2000ServiceTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail">
<ref bean="fy2000ServiceTask"></ref>
</property>
<property name="cronExpression">
<value>${service.cron}</value>
</property>
</bean>

<!-- 定时任务单 -->
<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="fy2000ServiceTrigger" />
            </list>
        </property>
    </bean>

3.配置文件 config.properties   

#webservice接口参数
service.queryParam=select * from .....
#司法公开今日动态cron表达式,每天早7点到晚7点每小时执行一次
service.cron=0 0 0 * * ?

4.所需jar包

quartz-1.6.*.jar 

spring-2.*.jar

.......

cron表达式详解 

一个cron表达式有至少6个(也可能是7个)由空格分隔的时间元素.从左到右,这些元素的定义如下: 
1.秒(0-59) 
2.分钟(0-59) 
3.小时(0-23) 
4.月份中的是期(1-31) 
5.月份(1-12或SUN-DEC) 
6.星期中的日期(1-7或SUN-SAT) 
7.年份(1970-2099) 
例子: 
0 0 10,14,16 * * ? 每天上午10点,下午2点和下午4点 
0 0,15,30,45 * 1-10 * ? 每月前10天每隔15分钟 
30 0 0 1 1 ? 2012 在2012年1月1日午夜过30秒时 
0 0 8-5 ? * MON-FRI 每个工作日的工作时间 
- 区间 
* 通配符 
? 你不想设置那个字段
