Spring 3整合Quartz 2实现手动设置定时任务：新增，修改，删除，暂停和恢复（附带源码）

摘要：在项目的管理功能中，对定时任务的管理有时会很常见。但一般定时任务配置都在xml中完成，包括cronExpression表达式，十分的方便。但是如果我的任务信息是保存在数据库的，想要动态的初始化，还有就是任务较多的时候不是得有一大堆的xml配置？或者说我要修改一下trigger的表达式，使原来5秒运行一次的任务变成10秒运行一次，或者说我要控制定时任务的 “ 暂停 ” 呢？暂停之后又要在某个时间点 “ 重启 ” 该定时任务呢？或者说直接 “ 删除 ” 该定时任务呢？要 改变某定时任务的触发时间呢？这时问题就来了，试过在配置文件中不传入cronExpression等参数，但是启动时就报错了，难道我每次都修改xml文件然后重启应用吗，这显然不合适的。

最理想的是在与spring整合的同时又能实现动态任务的添加、删除及修改配置，而且不需要重启应用。

 首先我们来回顾一下spring中使用quartz的配置代码：

<!-- 使用MethodInvokingJobDetailFactoryBean，任务类可以不实现Job接口，通过targetMethod指定调用方法-->
<bean id="taskJob" class="com.tyyd.dw.task.DataConversionTask"/>
<bean id="jobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
    <property name="group" value="job_work"/>
    <property name="name" value="job_work_name"/>
    <!--false表示等上一个任务执行完后再开启新的任务-->
    <property name="concurrent" value="false"/>
    <property name="targetObject">
        <ref bean="taskJob"/>
    </property>
    <property name="targetMethod">
        <value>execute</value>
    </property>
</bean>
<!--  调度触发器 -->
<bean id="myTrigger"
      class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
    <property name="name" value="work_default_name"/>
    <property name="group" value="work_default"/>
    <property name="jobDetail">
        <ref bean="jobDetail" />
    </property>
    <property name="cronExpression">
        <value>0/5 * * * * ?</value>
    </property>
</bean>
<!-- 调度工厂 -->
<bean id="scheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="triggers">
        <list>
            <ref bean="myTrigger"/>
        </list>
    </property>
</bean>

所有的配置都在xml中完成，包括cronExpression表达式，十分的方便。但是如果定时任务一多并且需要手动变化时，就得有一大堆的xml配置，不方便管理。

于是在设计时我想到以下几点

1、减少spring的配置文件。

2、用户可以通过页面等方式添加、启用、禁用某个任务。

3、用户可以修改某个已经在运行任务的运行时间表达式，即CronExpression。

4、为方便维护，简化任务的运行调用处理，任务的运行入口即Job实现类最好只有一个，该Job运行类相当于工厂类，在实际调用时把任务的相关信息通过参数方式传入，由该工厂类根据任务信息来具体执行需要的操作。

就像如下图所示：

1、可在页面直接查看任务详情

 

2、可添加、修改

3、可立即执行，并查看执行详情

 

在上面的思路下来进行我们的开发吧。

一、初始化用的数据库脚本

SET FOREIGN_KEY_CHECKS=0;

-- ----------------------------
-- Table structure for task_detail
-- ----------------------------
DROP TABLE IF EXISTS `task_detail`;
CREATE TABLE `task_detail` (
  `job_id` int(100) NOT NULL AUTO_INCREMENT,
  `job_name` varchar(200) DEFAULT NULL COMMENT '任务名称',
  `job_group` varchar(100) DEFAULT NULL COMMENT '任务分组',
  `job_status` varchar(5) DEFAULT NULL COMMENT '任务状态 0禁用 1启用 2删除',
  `cron_expression` varchar(200) DEFAULT NULL COMMENT '任务运行时间表达式',
  `bean_class` varchar(300) DEFAULT NULL COMMENT '任务执行类',
  `execute_method` varchar(100) DEFAULT NULL COMMENT '任务执行方法',
  `create_time` date DEFAULT NULL COMMENT '任务创建时间',
  `update_time` date DEFAULT NULL COMMENT '任务更新时间',
  `job_desc` varchar(500) DEFAULT NULL COMMENT '任务描述',
  PRIMARY KEY (`job_id`)
) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8;

-- ----------------------------
-- Records of task_detail
-- ----------------------------
INSERT INTO `task_detail` VALUES ('9', '测试手动设置任务', 'testQuartzTask', null, '0 0 1 * * ?', 'com.zealer.cps.task.executor.TestQuartzTask', 'printOneWord', '2017-06-22', '2017-06-22', '打印一句话');

 然后创建对应的实体类ScheduleJob.java

package com.zealer.cps.task.value;

/**
 * 定时任务封装类
 * @author   xiaohe
 */
public class ScheduleJob
{
    /** 任务id */
    private int jobId;
    
    /** 任务名称 */
    private String jobName;
    
    /** 任务分组 */
    private String jobGroup;
    
    /** 任务状态 0禁用 1启用 2删除*/
    private String jobStatus;
    
    /** 任务运行时间表达式 */
    private String cronExpression;
    
    /** 任务执行类 */
    private String beanClass;
    
    /** 任务执行方法 */
    private String executeMethod;
    
    /** 任务创建时间 */
    private String createTime;
    
    /** 任务更新时间 */
    private String updateTime;
    
    /** 任务描述 */
    private String jobDesc;
   
    //set与get方法这里省略，大家可以自己生成
    ......  
}

二、spring配置文件spring.xml

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

然后在web.xml加入

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring.xml</param-value>
</context-param>

三、编写任务控制器TaskController.java

package com.zealer.cps.task.controller;

四、编写任务运行入口，即JobMethod.java

{
    @Resource( name = "schedulerFactoryBean" )
    private Scheduler scheduler;

    @Resource( name = "quartzJobService" )
    private QuartzJobService quartzJobService;

    private static Log log = LogFactory.getLog( JobMethod.class );


    /**

        List<ScheduleJob> jobList = quartzJobService.getAllJobs();

        if ( jobList != null && !jobList.isEmpty() )
        {
            for ( ScheduleJob scheduleJob : jobList )
            {

                        jobDetail.getJobDataMap().put( "scheduleJob",
                                     scheduleJob );

                        CronScheduleBuilder scheduleBuilder = CronScheduleBuilder

六、编写sql映射xml文件QuartzJob.xml

七、修改和列表页面

 到这里，我们的spring3 整合quartz 2的定时任务功能终于是告一段落了，对常用的一些功能进行了实现，相信可以满足一般项目的需求了。
