Spring整合Quartz實現(xiàn)動態(tài)定時器的示例代碼

更新時間：2017年01月19日 10:29:05 作者：五指少年

本篇文章主要介紹了Spring整合Quartz實現(xiàn)動態(tài)定時器的示例代碼，具有一定的參考價值，感興趣的小伙伴們可以參考一下。

一、版本說明

spring3.1以下的版本必須使用quartz1.x系列，3.1以上的版本才支持quartz 2.x，不然會出錯。

原因：spring對于quartz的支持實現(xiàn)，org.springframework.scheduling.quartz.CronTriggerBean繼承了org.quartz.CronTrigger，在quartz1.x系列中org.quartz.CronTrigger是個類，而在quartz2.x系列中org.quartz.CronTrigger變成了接口，從而造成無法用spring的方式配置quartz的觸發(fā)器（trigger）

此示例所選版本：spring版本號3.0.7.RELEASE，quartz版本1.8.6

二、添加jar包

我的是maven工程，pom.xml相關配置如下：

 <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <spring.version>3.0.7.RELEASE</spring.version>
    <quartz.version>1.8.6</quartz.version>
  </properties>

 　　　　<dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-context</artifactId>
      <version>${spring.version}</version>
      <exclusions>
        <!-- Exclude Commons Logging in favor of SLF4j -->
        <exclusion>
          <groupId>commons-logging</groupId>
          <artifactId>commons-logging</artifactId>
        </exclusion>
      </exclusions>
    </dependency>

    <dependency><!--3.0.7沒這個包 -->
      <groupId>org.springframework</groupId>
      <artifactId>spring-context-support</artifactId>
      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-webmvc</artifactId>
      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-orm</artifactId>
      <version>${spring.version}</version>
      <type>jar</type>
      <scope>compile</scope>
    </dependency>

    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-test</artifactId>
      <version>${spring.version}</version>
      <type>jar</type>
      <scope>test</scope>
    </dependency>

 <dependency>
      <groupId>org.quartz-scheduler</groupId>
      <artifactId>quartz</artifactId>
      <version>${quartz.version}</version>
    </dependency>

三、整合實現(xiàn)

1、spring配置

spring只需要添加quartz調(diào)度工廠bean就可以了

復制代碼代碼如下:

<bean id="schedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean" />

2、定時器工作類實現(xiàn)

定義定時器作業(yè)類，該類繼承自job類

package com.ld.nhmz.quartz;

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

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

/**
 * quartz示例定時器類
 * 
 * @author Administrator
 * 
 */
public class QuartzJobExample implements Job {
  @Override
  public void execute(JobExecutionContext arg0) throws JobExecutionException {
    System.out.println(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()) + "★★★★★★★★★★★");
  }
}

定義定時器管理類

package com.ld.nhmz.quartz;

import org.quartz.CronTrigger;
import org.quartz.JobDetail;
import org.quartz.Scheduler;

/**
 * Quartz調(diào)度管理器
 * 
 * @author Administrator

public class QuartzManager {
  private static String JOB_GROUP_NAME = "EXTJWEB_JOBGROUP_NAME";
  private static String TRIGGER_GROUP_NAME = "EXTJWEB_TRIGGERGROUP_NAME";

      sched.scheduleJob(jobDetail, trigger);
      // 啟動
      if (!sched.isShutdown()) {
        sched.start();
      }
    } catch (Exception e) {
      throw new RuntimeException(e);
    }
  }

測試代碼，這里SchedulerFactory沒有使用spring中配置的bean，而是new出來的，做測試用

package com.ld.nhmz.quartz.test;

import org.junit.Test;
import org.quartz.Scheduler;
import org.quartz.SchedulerFactory;
import org.quartz.impl.StdSchedulerFactory;

import com.ld.nhmz.quartz.QuartzJobExample;
import com.ld.nhmz.quartz.QuartzManager;

/**
 * @Description: 測試類
 * 
 * @ClassName: QuartzTest.java
 */
public class QuartzTest {
  @Test
  public void quartz() {
    try {
      SchedulerFactory gSchedulerFactory = new StdSchedulerFactory();
      Scheduler sche = gSchedulerFactory.getScheduler();
      String job_name = "動態(tài)任務調(diào)度";
      System.out.println("【系統(tǒng)啟動】開始(每1秒輸出一次)...");
      QuartzManager.addJob(sche, job_name, QuartzJobExample.class, "0/1 * * * * ?");

      Thread.sleep(3000);
      System.out.println("【修改時間】開始(每2秒輸出一次)...");
      QuartzManager.modifyJobTime(sche, job_name, "10/2 * * * * ?");
      Thread.sleep(4000);
      System.out.println("【移除定時】開始...");
      QuartzManager.removeJob(sche, job_name);
      System.out.println("【移除定時】成功");

      System.out.println("【再次添加定時任務】開始(每10秒輸出一次)...");
      QuartzManager.addJob(sche, job_name, QuartzJobExample.class, "*/10 * * * * ?");
      Thread.sleep(30000);
      System.out.println("【移除定時】開始...");
      QuartzManager.removeJob(sche, job_name);
      System.out.println("【移除定時】成功");
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}
