1、环境:Spring3.1+Quartz1.8(Spring3.*和Quartz2.*整合报错,改用Quartz1.8版本)
2、查询剩余表空间Job:
package com.sxit.job; import org.quartz.JobExecutionContext; import org.quartz.JobExecutionException; import org.springframework.scheduling.quartz.QuartzJobBean; /** * @功能:查询表空间Job * @作者: smile * @时间:2013-4-8 下午4:53:22 * @版本:1.0 */ public class TableSpaceSmsAlarmJob extends QuartzJobBean{ @Override protected void executeInternal(JobExecutionContext context) throws JobExecutionException { TableSpaceSmsAlarm alarm = new TableSpaceSmsAlarm(); alarm.queryTableSpace(); } }
3、处理类TableSpaceSmsAlarm :
package com.sxit.job; import org.apache.log4j.Logger; import java.io.File; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.IOException; import java.io.InputStream; import java.net.URL; import java.sql.Connection; import java.sql.PreparedStatement; import java.sql.ResultSet; import java.sql.SQLException; import java.util.Properties; import com.sxit.util.ConnectionUtil; import com.sxit.util.SendPwdService; /** * @功能:表空间短信报警 * @作者: smile * @时间:2013-4-8 下午3:51:35 * @版本:1.0 */ public class TableSpaceSmsAlarm { private static final Logger logger = Logger.getLogger(TableSpaceSmsAlarm.class); /** 表空间警告阀值 */ private static int tableSpaceSize; /** 手机号 */ private static String mobileStr; public TableSpaceSmsAlarm(){ init(); } /** * @功能:初始化参数 */ public void init(){ Properties pro = new Properties(); InputStream is = null; try { String separator = System.getProperty("file.separator"); URL url = Thread.currentThread().getContextClassLoader().getResource(""); File f = new File(url.getPath() + separator + "config.properties"); is = new FileInputStream(f); pro.clear(); pro.load(is); tableSpaceSize = Integer.parseInt(pro.get("tableSpaceSize").toString()); mobileStr = pro.getProperty("mobileStr").toString(); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } finally { if (is != null) try { is.close(); } catch (IOException e) { e.printStackTrace(); } finally{ is = null; } } } /** * @功能:查询空闲表空间 */ public void queryTableSpace(){ Connection con = ConnectionUtil.getConnection(); PreparedStatement ps = null; ResultSet rs = null; int freeSpace = 0; String sql = "select round(sum(bytes)/1024/1024) freespace " +" from dba_free_space " +" where tablespace_name='LNXXT'"; try { ps = con.prepareStatement(sql); rs = ps.executeQuery(); if(rs.next()){ freeSpace = rs.getInt("freespace"); //小于当前阀值 发送短信 if(freeSpace <= tableSpaceSize){ SendPwdService send = new SendPwdService(); if(mobileStr!=null && mobileStr.length()>0){ String[] mobile = mobileStr.split(","); for(String phone : mobile){ send.sendSMS(con, phone, freeSpace); } }else{ logger.info("配置文件出错,手机号码为空!"); //系统退出 System.exit(0); } } } } catch (SQLException e) { e.printStackTrace(); } finally{ ConnectionUtil.freeAll(con, ps, rs); } } }
4、配置文件config.properties:
#表空间大小警告阀值 tableSpaceSize=10240 #手机号 以逗号分隔 mobileStr=158********,159********,150********
5、Spring配置文件:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd"> <!-- 定义调度工作任务 --> <bean id="alarmBean" class="org.springframework.scheduling.quartz.JobDetailBean"> <property name="jobClass" value="com.sxit.job.TableSpaceSmsAlarmJob" /> </bean> <bean id="alarmTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean"> <property name="jobDetail" ref="alarmBean" /> <!-- 每天7点到23这个时间段 每隔一小时执行job一次 --> <property name="cronExpression" value="0 0/59 7-23 * * ?" /> </bean> <!-- <bean id="alarmTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean"> <property name="jobDetail" ref="alarmBean" /> <property name="repeatInterval" value="10000" /> </bean> --> <!-- 启动调度 --> <bean id="scheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="triggers"> <list> <ref bean="alarmTrigger" /> </list> </property> </bean> </beans>
6、web.xml配置:
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <!-- 定义Spring配置文件位置 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- 对Spring容器进行实例化 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> </web-app>
