定时任务-Quartz(热部署、冷部署)

一、配置Quartz.xml

 <beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:context="http://www.springframework.org/schema/context"
  xmlns:p="http://www.springframework.org/schema/p"
  xmlns:mvc="http://www.springframework.org/schema/mvc"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

      <!-- 要调用的工作类 -->
     <bean id="jobclass" class="com.sh.test.dingshi"></bean>

      <!-- 配置方法调用 -->
     <bean id="conJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
         <property name="targetObject" ref="jobclass"></property>
         <property name="targetMethod" value="say"></property>
         <!-- 是否允许同时运行 -->
         <property name="concurrent" value="false"></property>
     </bean>

     <!-- 定时重复执行 -->
      <bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
         <property name="jobDetail" ref="conJob"></property>
         <property name="cronExpression" >
             <value>0/5 * * ? * * </value><!-- 配置5秒执行一次 -->
         </property>
     </bean>

     <!-- 定时任务配置,定时工厂,用于管理配置的所有定时器，保证其在单独的线程上运行 -->
     <bean id="quartzfactory" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
         <property name="triggers">
             <list>
                 <ref local="cronTrigger"/><!-- 注册开关，local为上面配置的-->
             </list>
         </property>
     </bean>

 </beans>

spring-dingshi.xml

二、导入jar

quartz-1.8.5.jar

三、创建冷部署的定时任务类，dingshi.java

 package com.sh.test;

 import java.text.SimpleDateFormat;
 import java.util.Date;

 import org.springframework.stereotype.Service;

 @Service("dingshi")
 public class dingshi {
     public void say(){
         String format = "yyyy-MM-dd HH:mm:ss";
         SimpleDateFormat sdf = new SimpleDateFormat(format);
         System.out.println("定时循环执行:"+sdf.format(new Date()));
     }
 }

这配置有两种方式

注解方式：

1.通过在任务类(dingshi.java)中配置注解@Service("dingshi")

2.在配置文件(spring-dingshi.xml)中第18行配置ref="dingshi"，无需第14行

非注解方式：

1.在配置文件(spring-dingshi.xml)中配置第14行内容，在第18行ref=“id”配置18行的id

四、配置热部署管理类

 package com.sh.test;

 import org.quartz.CronTrigger;
 import org.quartz.JobDetail;
 import org.quartz.Scheduler;
 import org.quartz.SchedulerFactory;
 import org.quartz.impl.StdSchedulerFactory;

     @SuppressWarnings("unchecked")

             if (!sched.isShutdown()) {
                 sched.start();

五、热部署执行类

 package com.sh.test;

 import java.text.SimpleDateFormat;
 import java.util.Date;

 import org.quartz.Job;
 import org.quartz.JobExecutionContext;
 import org.quartz.JobExecutionException;

 /**
  * @Description: 任务执行类
  *
  * @ClassName: QuartzJob
  * @Copyright: Copyright (c) 2015
  *
  * @author SH
  * @version V2.0
  */
 public class QuartzJob implements Job {

     public void execute(JobExecutionContext arg0) throws JobExecutionException {
         String name = arg0.getTrigger().getName();//获得当前执行任务名
         System.out.println(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));
     }
 }

QuartzJob.java

六、热部署测试类

 package com.sh.test;

 import javax.servlet.http.HttpServletRequest;
 import javax.servlet.http.HttpServletResponse;

 import org.springframework.stereotype.Controller;
 import org.springframework.web.bind.annotation.RequestMapping;
 import org.springframework.web.bind.annotation.RequestMethod;

 /**

  *
  * @ClassName: QuartzTest
  * @Copyright: Copyright (c) 2014
  *
  * @author SH
  * @version V2.0
  */
 @Controller
 public class QuartzTest {
     public static void main(String[] args) {
         try {
             String job_name = "动态任务调度";
             System.out.println("【系统启动】开始(每1秒输出一次)...");

             QuartzManager.modifyJobTime(job_name, "10/2 * * * * ?");
             Thread.sleep(6000);
             System.out.println("【移除定时】开始...");
             QuartzManager.removeJob(job_name);
