三、配置数据库连接池?
配置jdbc.properties文件?

jdbc.username=root?

cpool.checkoutTimeout=5000?
cpool.minPoolSize=10?
cpool.maxPoolSize=25?
cpool.maxIdleTime=7200?
cpool.acquireIncrement=5?
cpool.autoCommitOnClose=true?
配置applicationContext.xml文件?

这里只是配置了数据连接池,我使用c3p0 连接池,还没有涉及到Quartx有关配置,下面且听我慢慢道来。?
四、实现动态定时任务?
? 什么是动态定时任务:是由客户制定生成的,服务端只知道该去执行什么任务,但任务的定时是不确定的(是由客户制定)。?
这样总不能修改配置文件每定制个定时任务就增加一个trigger吧,即便允许客户修改配置文件,但总需要重新启动web服务啊,研究了下Quartz在Spring中的动态定时,发现?
引用
<bean id="cronTrigger" >?
???????? <property name="jobDetail" ref="schedulerJobDetail"/>?
???????? <property name="cronExpression">?
???????????? <value>0/10 * * * * ?</value>?
???????? </property>?
中cronExpression是关键,如果可以动态设置cronExpression的值,就可以顺利解决问题了。这样我们就不能直接使用org.springframework.scheduling.quartz.CronTriggerBean,需要自己实现一个动态调度服务类,在其中构建CronTrigger或SimpleTrigger,动态配置时间。?
动态调度服务接口:?

SchedulerService 只有一个多态方法schedule,SchedulerServiceImpl实现SchedulerService接口,注入org.quartz.Schedulert和org.quartz.JobDetail,schedule方法可以动态配置org.quartz.CronExpression或org.quartz.SimpleTrigger调度时间。?
五、实现自己的org.quartz.JobDetail?
在上一步中SchedulerServiceImpl需要注入org.quartz.JobDetail,在以前的静态配置中?
引用
<bean id="jobDetail" ref="simpleService" />?
<property name="targetMethod" value="testMethod" />?
</bean>
中使用org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean。在这里使用org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean。会报?

异常,google了一下,没有找到解决方法。所以在这里不能使用org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean。,不能pojo了,需要使用org.springframework.scheduling.quartz.JobDetailBean和org.springframework.scheduling.quartz.QuartzJobBean实现自己的QuartzJobBean,如下:?
Java代码??
- package?com.sundoctor.example.service;??
- ??
- import?org.quartz.JobExecutionContext;??
- import?org.quartz.JobExecutionException;??
- import?org.quartz.Trigger;??
- import?org.springframework.scheduling.quartz.QuartzJobBean;??
- ??
- public?class?MyQuartzJobBean?extends?QuartzJobBean?{??
- ??
- ????private?SimpleService?simpleService;??
- ??????
- ????public?void?setSimpleService(SimpleService?simpleService)?{??
- ????????this.simpleService?=?simpleService;??
- ????}??
- ??
- ????@Override??
- ????protected?void?executeInternal(JobExecutionContext?jobexecutioncontext)?throws?JobExecutionException?{??
- ????????Trigger?trigger?=?jobexecutioncontext.getTrigger();??
- ????????String?triggerName?=?trigger.getName();???????
- ????????simpleService.testMethod(triggerName);??
- ????}??
- ??
- }??
MyQuartzJobBean继承org.springframework.scheduling.quartz.QuartzJobBean,注入的SimpleService如下:?
Java代码??
- package?com.sundoctor.example.service;??
- ??
- import?java.io.Serializable;??
- ??
- import?org.slf4j.Logger;??
- import?org.slf4j.LoggerFactory;??
- import?org.springframework.stereotype.Service;??
- ??
- @Service("simpleService")??
- public?class?SimpleService?implements?Serializable{??
- ??????
- ????private?static?final?long?serialVersionUID?=?122323233244334343L;??
- ????private?static?final?Logger?logger?=?LoggerFactory.getLogger(SimpleService.class);??
- ??????
- ????public?void?testMethod(String?triggerName){??
- ????????//这里执行定时调度业务??
- ????????logger.info(triggerName);??
- ????}??
- ??????
- ????public?void?testMethod2(){??
- ????????logger.info("testMethod2");??
- ????}??
- }??
SimpleService主要执行定时调度业务,在这里我只是简单打印一下log日志。SimpleService需要实现java.io.Serializable接口,否则会报?

中需要注入调度业务类,否则会报空指指错误。?
dataSource:项目中用到的数据源,里面包含了quartz用到的12张数据库表;?
applicationContextSchedulerContextKey: 是org.springframework.scheduling.quartz.SchedulerFactoryBean这个类中把spring上下文以key/value的方式存放在了quartz的上下文中了,可以用applicationContextSchedulerContextKey所定义的key得到对应的spring上下文;?
configLocation:用于指明quartz的配置文件的位置,如果不用spring配置quartz的话,本身quartz是通过一个配置文件进行配置的,默认名称是quartz.properties,里面配置的参数在quartz的doc文档中都有介绍,可以调整quartz,我在项目中也用这个文件部分的配置了一些属性,代码如下:?

这样只是简单的将quartz trigger名称打印出来。?
这样通过SchedulerService就可以动态配置调度时间。其实SchedulerService 还可扩展,比如可以注入多个JobDetail,调度不同的JobDetail。?
