spring 通过配置向quartz 注入service

如何通过spring 向quartz动态注入service或者，传入动态参数？
这里主要用到了org.springframework.scheduling.quartz.JobDetailBean这个类的setJobDataAsMap的这个方法！
具体的API如下：
setJobDataAsMap
public void setJobDataAsMap(Map jobDataAsMap)

    Register objects in the JobDataMap via a given Map.

    These objects will be available to this Job only, in contrast to objects in the SchedulerContext.

   Note: When using persistent Jobs whose JobDetail will be kept in the database, do not put Spring-managed beans or an ApplicationContext reference into the JobDataMap but rather into the SchedulerContext.

    Parameters:
        jobDataAsMap - Map with String keys and any objects as values (for example Spring-managed beans)
需要注意的是红色的部分，由spring管理的Service无法通过这个方法进行注入，
spring管理的service 只能放到SchedulerContext里面。
好的，我们来举个例子。

   

<bean name="quartzScheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="dataSource" ref="dataSource" />

        <property name="schedulerContextAsMap">
            <map>
                <!-- spring 管理的service需要放到这里，才能够注入成功 -->
                <description>schedulerContextAsMap</description>
                <entry key="webSiteService" value-ref="webSiteService"/>
                <entry key = "mappingService" value-ref="mappingService"/>
                <entry key="detailService" value-ref = "detailService"></entry>
            </map>
        </property>
        <property name="applicationContextSchedulerContextKey" value="applicationContextKey" />
        <property name="configLocation" value="classpath:quartz.properties" />
    </bean>

    <bean id="jobDetail" class="org.springframework.scheduling.quartz.JobDetailBean">
        <property name="jobClass" value = "com.fangjia.dc.quartz.MyQuartzJob"/>
        <property name="jobDataAsMap">
            <map>
                <!-- 非spring管理的service放到这里，就可以注入进去 -->
                <description>jobDataAsMap</description>
                <!-- key 属性值，value 对应的bean -->
                <entry key="uploader" value-ref="uploader" />
            </map>
        </property>
    </bean>

<bean name="quartzScheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">   
        <property name="dataSource" ref="dataSource" />    
            
        <property name="schedulerContextAsMap">    
            <map>    
                <!-- spring 管理的service需要放到这里，才能够注入成功 -->    
                <description>schedulerContextAsMap</description>    
                <entry key="webSiteService" value-ref="webSiteService"/>    
                <entry key = "mappingService" value-ref="mappingService"/>    
                <entry key="detailService" value-ref = "detailService"></entry>   
            </map>    
        </property>    
        <property name="applicationContextSchedulerContextKey" value="applicationContextKey" />   
        <property name="configLocation" value="classpath:quartz.properties" />   
    </bean>    
        
    <bean id="jobDetail" class="org.springframework.scheduling.quartz.JobDetailBean">   
        <property name="jobClass" value = "com.fangjia.dc.quartz.MyQuartzJob"/>   
        <property name="jobDataAsMap">    
            <map>    
                <!-- 非spring管理的service放到这里，就可以注入进去 -->    
                <description>jobDataAsMap</description>    
                <!-- key 属性值，value 对应的bean -->    
                <entry key="uploader" value-ref="uploader" />    
            </map>    
        </property>    
    </bean>

 

这里一共注入了 bean，分别是webSiteService，mappingService，detailService和uploader，然后在MyQuartzJob中使用注入的service 

 

public class MyQuartzJob extends QuartzJobBean {

    private static final Logger logger = Logger.getLogger(MyQuartzJob.class);
    private Uploader uploader;
    private IService<WebSite> webSiteService;
    private IService<Mapping> mappingService;
    private IService<MappingDetail> detailService;

    @Override
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {

        try {
            //获取JobExecutionContext中的service对象
            SchedulerContext skedCtx = context.getScheduler().getContext();
            //获取SchedulerContext中的service
            //这里的service就是通过配置文件 配置的
            webSiteService = (IService<WebSite>)skedCtx.get("webSiteService");
            mappingService = (IService<Mapping>)skedCtx.get("mappingService");
            detailService = (IService<MappingDetail>)skedCtx.get("detailService");

            //获取 当前的trigger 名称，
            Trigger trigger = context.getTrigger();
            String name = trigger.getName();

            //从trigger中的jobDataMap中获取uploader
            uploader = (Uploader) context.getJobDetail.getJobDataMap().get("uploader");

            WebSite webSite = webSiteService.findByName(name);
            logger.info("webSite id:" + webSite.getId());
            loadMappingConfiguration(webSite);
            uploader.process(webSite, typeXpathFiels, domainMap);
        } catch (SchedulerException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }

    }
    //属性的 get set方法
}

public class MyQuartzJob extends QuartzJobBean {   
  
    private static final Logger logger = Logger.getLogger(MyQuartzJob.class);   
    private Uploader uploader;     
    private IService<WebSite> webSiteService;   
    private IService<Mapping> mappingService;   
    private IService<MappingDetail> detailService;   
       
    @Override  
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {  
           
        try {   
            //获取JobExecutionContext中的service对象  
            SchedulerContext skedCtx = context.getScheduler().getContext();   
            //获取SchedulerContext中的service  
            //这里的service就是通过配置文件 配置的  
            webSiteService = (IService<WebSite>)skedCtx.get("webSiteService");   
            mappingService = (IService<Mapping>)skedCtx.get("mappingService");   
            detailService = (IService<MappingDetail>)skedCtx.get("detailService");  
               
            //获取 当前的trigger 名称，  
            Trigger trigger = context.getTrigger();   
            String name = trigger.getName();   
  
            //从trigger中的jobDataMap中获取uploader  
            uploader = (Uploader) context.getJobDetail.getJobDataMap().get("uploader");   
  
            WebSite webSite = webSiteService.findByName(name);   
            logger.info("webSite id:" + webSite.getId());   
            loadMappingConfiguration(webSite);   
            uploader.process(webSite, typeXpathFiels, domainMap);   
        } catch (SchedulerException e) {   
            e.printStackTrace();   
        } catch (Exception e) {   
            e.printStackTrace();   
        }   
           
    }   
    //属性的 get set方法  
}

定时任务的动态管理，没有配置的spring文件中
采用页面传值，实现quartz定时任务的CRUD

 

public void schedule(String name, CronExpression cronExpression,String group) throws SchedulerException {

        //添加Job 给scheduler,允许 replace

        jobDetail.setRequestsRecovery(true);
        //孤立线程 不再保存在DB中
        jobDetail.setDurability(false);
        jobDetail.setName(name);
        logger.info(" is  durable:" + jobDetail.isDurable());
        //设置replace为true，相同名字的job存在，则替换
        scheduler.addJob(jobDetail, true);

        CronTrigger cronTrigger = new CronTrigger(name, group, jobDetail.getName(), Scheduler.DEFAULT_GROUP);
        cronTrigger.setCronExpression(cronExpression);
        scheduler.scheduleJob(cronTrigger);
        scheduler.rescheduleJob(cronTrigger.getName(), cronTrigger.getGroup(), cronTrigger);
    }

    public void pauseTrigger(String triggerName, String group) throws SchedulerException {
        logger.info("pause triggerName:" + triggerName);
        scheduler.pauseTrigger(triggerName, group);
    }

    public void resumeTrigger(String triggerName, String group) throws SchedulerException {
        logger.info("resume trigger:" + triggerName + " group:" + group);
        scheduler.resumeTrigger(triggerName, group);
    }

    public boolean removeTrigdger(String triggerName, String group) throws SchedulerException {
        scheduler.pauseTrigger(triggerName, group);
        return scheduler.unscheduleJob(triggerName, group);
    }

public void schedule(String name, CronExpression cronExpression,String group) throws SchedulerException {  
           
        //添加Job 给scheduler,允许 replace  
           
        jobDetail.setRequestsRecovery(true);   
        //孤立线程 不再保存在DB中  
        jobDetail.setDurability(false);   
        jobDetail.setName(name);   
        logger.info(" is  durable:" + jobDetail.isDurable());   
        //设置replace为true，相同名字的job存在，则替换  
        scheduler.addJob(jobDetail, true);   
           
        CronTrigger cronTrigger = new CronTrigger(name, group, jobDetail.getName(), Scheduler.DEFAULT_GROUP);  
        cronTrigger.setCronExpression(cronExpression);   
        scheduler.scheduleJob(cronTrigger);   
        scheduler.rescheduleJob(cronTrigger.getName(), cronTrigger.getGroup(), cronTrigger);  
    }   
  
    public void pauseTrigger(String triggerName, String group) throws SchedulerException {  
        logger.info("pause triggerName:" + triggerName);   
        scheduler.pauseTrigger(triggerName, group);   
    }   
  
    public void resumeTrigger(String triggerName, String group) throws SchedulerException {  
        logger.info("resume trigger:" + triggerName + " group:" + group);   
        scheduler.resumeTrigger(triggerName, group);   
    }   
  
    public boolean removeTrigdger(String triggerName, String group) throws SchedulerException {  
        scheduler.pauseTrigger(triggerName, group);   
        return scheduler.unscheduleJob(triggerName, group);   
    }
