这里要使用到com.springsource.org.quartz-1.6.2.jar包，以及spring的开发包

首先创建定时石英任务

/*
     * 创建日志表的石英任务
     * */
    public class CreateLogTablesTask extends QuartzJobBean {
    
    	
    	private LogService logService;
    	//注入LogService
    	public LogService getLogService() {
    		return logService;
    	}
    	public void setLogService(LogService logService) {
    		this.logService = logService;
    	}
    	/*生成日志表，其中参数 0表示当月  1表示下个月，2表示下二个月*/
    	protected void executeInternal(JobExecutionContext arg0) throws JobExecutionException {
    	
    		
    		//下一个月
    		String tableName=LogUtil.generaterLogTableName(1);
    		//生成日志表
    		logService.createLogTable(tableName);
    		//下两个月
    		tableName=LogUtil.generaterLogTableName(2);
    		//生成日志表
    		logService.createLogTable(tableName);
    		//下三个月
    		tableName=LogUtil.generaterLogTableName(3);
    		//生成日志表
    		logService.createLogTable(tableName);
    	}
    
    }

上面任务中需要用到LogUtil类中的generaterLogTableName方法，来产生表的名字。

然后在spring的配置文件applicationContext.xml中加上如下配置：

<bean id="jobDetailBean"  class="org.springframework.scheduling.quartz.JobDetailBean">
    
    	<property name="jobClass" value="com.ssh_surveypart.scheduler.CreateLogTablesTask"></property>
    	<property name="jobDataMap">
    		<map>
    			<entry key="logService" value-ref="logServiceImpl"></entry>
    		</map>
    	</property>
    </bean>
    
    <bean id="cronTriggerBean" class="org.springframework.scheduling.quartz.CronTriggerBean">
    	<property name="jobDetail" ref="jobDetailBean"></property>
    	<property name="cronExpression">
    	
    		<value>0 13 12 12 * ?</value>
    	</property>
    </bean>
    
    
    <bean id="schedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    	<property name="triggers">
    		<list>
    			<ref bean="cronTriggerBean"/>
    		</list>
    	</property>
    </bean>
