# 前言 #

本文是对之前的一篇文章[Spring+SpringMVC+mybatis+Quartz整合][Spring_SpringMVC_mybatis_Quartz]代码部分做的一个修改和补充， 其中最大的变化就是后台框架变成了Spring Boot。

本工程所用到的技术或工具有：

*  **Spring Boot**
 *  **Mybatis**
 *  **Quartz**
 *  **PageHelper**
 *  **VueJS**
 *  **ElementUI**
 *  **MySql数据库**

--------------------

# 正文 #

## 配置 ##

本例中仍然是使用mysql数据库作为Quartz任务持久化的存储载体。对于如何在Mysql数据库中建立表，在上一篇[Spring+SpringMVC+mybatis+Quartz整合][Spring_SpringMVC_mybatis_Quartz]中已经有了详细的介绍。这里我们来看Spring Boot工程的建立方法。在[Spring网站][Spring]上有关于建立Spring Boot工程的脚手架，我们按如下图的方式设置，然后点击Generate Project即可。

![这里写图片描述][SouthEast]

接着我们在IDE中导入这个maven工程，然后可以看到src/main/resource下面有一个名字为application.properties的文件，里面的内容是空的。我们删除这个文件，然后在这个目录下新建一个名为application.yml的文件。这是配置Spring Boot工程的另一种方式，也是Spring Boot官方推荐的一种配置方式。我们在新建的这个yml文件中，加入如下代码

spring:
      datasource:
        url: jdbc:mysql://190.0.1.88:3306/hello_test?useUnicode=true
        username: root
        password: root
        driver-class-name: com.mysql.jdbc.Driver
    
    mybatis: 
      mapper-locations:
      - classpath:com/example/demo/mapper/*.xml
      type-aliases-package: com.example.demo.entity

上面的代码是对数据库和mybatis的一些配置。

接着我们在当前目录下再新建一个名为quartz.properties的文件。这是对Quartz的配置文件。加入如下代码：

# 固定前缀org.quartz
    # 主要分为scheduler、threadPool、jobStore、plugin等部分
    #
    #
    org.quartz.scheduler.instanceName = DefaultQuartzScheduler
    org.quartz.scheduler.rmi.export = false
    org.quartz.scheduler.rmi.proxy = false
    org.quartz.scheduler.wrapJobExecutionInUserTransaction = false
    
    # 实例化ThreadPool时，使用的线程类为SimpleThreadPool
    org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
    
    # threadCount和threadPriority将以setter的形式注入ThreadPool实例
    # 并发个数
    org.quartz.threadPool.threadCount = 5
    # 优先级
    org.quartz.threadPool.threadPriority = 5
    org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true
    
    org.quartz.jobStore.misfireThreshold = 5000
    
    # 默认存储在内存中
    #org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore
    
    #持久化
    org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
    
    org.quartz.jobStore.tablePrefix = QRTZ_
    
    org.quartz.jobStore.dataSource = qzDS
    
    org.quartz.dataSource.qzDS.driver = com.mysql.jdbc.Driver
    
    org.quartz.dataSource.qzDS.URL = jdbc:mysql://190.0.1.88:3306/hello_test?useUnicode=true&characterEncoding=UTF-8
    
    org.quartz.dataSource.qzDS.user = root
    
    org.quartz.dataSource.qzDS.password = root
    
    org.quartz.dataSource.qzDS.maxConnections = 10

可以看出和上一篇文章的配置文件完成相同。接着我们在com.example.demo下新建一个名为SchedulerConfig.java的文件。在这个文件里，对刚才我们新建的quartz.properties文件进行读取。

package com.example.demo;
    
    import java.io.IOException;
    import java.util.Properties;
    
    import javax.sql.DataSource;
    
    import org.quartz.ee.servlet.QuartzInitializerListener;
    import org.springframework.beans.factory.config.PropertiesFactoryBean;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.core.io.ClassPathResource;
    import org.springframework.scheduling.quartz.SchedulerFactoryBean;
    
    @Configuration
    public class SchedulerConfig {
          
    
        @Bean
        public SchedulerFactoryBean schedulerFactoryBean(DataSource dataSource) throws IOException {
            SchedulerFactoryBean factory = new SchedulerFactoryBean();
            factory.setQuartzProperties(quartzProperties());
            return factory;
        }
    
        @Bean
        public Properties quartzProperties() throws IOException {
            PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
            propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties"));
            return propertiesFactoryBean.getObject();
        }
    
        @Bean
        public QuartzInitializerListener executorListener() {
           return new QuartzInitializerListener();
        }
    
    }

注意最下方的QuartzInitializerListener。在SpringMVC中，我们在配置Quartz的时候，要在web.xml中加入如下配置：

<listener>
            <listener-class>
                org.quartz.ee.servlet.QuartzInitializerListener
            </listener-class>
        </listener>

这个监听器可以监听到工程的启动，在工程停止再启动时可以让已有的定时任务继续进行。由于我们目前的工程是Spring Boot，没有web.xml的配置方式，所以我们在上文的SchedulerConfig类中直接注入了这个Bean。

## 实现 ##

先来看Job类。首先设置一个BaseJob接口，用来继承Job类：

package com.example.demo.job;
    
    import org.quartz.Job;
    import org.quartz.JobExecutionContext;
    import org.quartz.JobExecutionException;
    
    public interface BaseJob extends Job{
          
        public void execute(JobExecutionContext context) throws JobExecutionException;
    }

然后两个Job类用来实现BaseJob类：  
HelloJob

package com.example.demo.job;
    
    import java.util.Date;  
    import org.slf4j.Logger;  
    import org.slf4j.LoggerFactory;   
    import org.quartz.JobExecutionContext;  
    import org.quartz.JobExecutionException;  
    
    public class HelloJob implements BaseJob {
            
    
        private static Logger _log = LoggerFactory.getLogger(HelloJob.class);  
    
        public HelloJob() {  
    
        }  
    
        public void execute(JobExecutionContext context)  
            throws JobExecutionException {  
            _log.error("Hello Job执行时间: " + new Date());  
    
        }  
    }

NewJob

package com.example.demo.job;
    
    import java.util.Date;  
    import org.slf4j.Logger;  
    import org.slf4j.LoggerFactory;  
    import org.quartz.JobExecutionContext;  
    import org.quartz.JobExecutionException;  
    
    public class NewJob implements BaseJob {
            
    
        private static Logger _log = LoggerFactory.getLogger(NewJob.class);  
    
        public NewJob() {  
    
        }  
    
        public void execute(JobExecutionContext context)  
            throws JobExecutionException {  
            _log.error("New Job执行时间: " + new Date());  
    
        }  
    }

至于这样做的目的，我们可以先看一下Controller

package com.example.demo.controller;
    
    import java.util.HashMap;
    import java.util.Map;
    
    import org.quartz.CronScheduleBuilder;
    import org.quartz.CronTrigger;
    import org.quartz.JobBuilder;
    import org.quartz.JobDetail;
    import org.quartz.JobKey;
    import org.quartz.Scheduler;
    import org.quartz.SchedulerException;
    import org.quartz.SchedulerFactory;
    import org.quartz.TriggerBuilder;
    import org.quartz.TriggerKey;
    import org.quartz.impl.StdSchedulerFactory;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.PostMapping;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestParam;
    import org.springframework.web.bind.annotation.RestController;
    
    import com.example.demo.entity.JobAndTrigger;
    import com.example.demo.job.BaseJob;
    import com.example.demo.service.IJobAndTriggerService;
    import com.github.pagehelper.PageInfo;
    
    
    @RestController
    @RequestMapping(value="/job")
    public class JobController 
    {
          
        @Autowired
        private IJobAndTriggerService iJobAndTriggerService;
    
        private static Logger log = LoggerFactory.getLogger(JobController.class);  
    
    
        @PostMapping(value="/addjob")
        public void addjob(@RequestParam(value="jobClassName")String jobClassName, 
                @RequestParam(value="jobGroupName")String jobGroupName, 
                @RequestParam(value="cronExpression")String cronExpression) throws Exception
        {           
            addJob(jobClassName, jobGroupName, cronExpression);
        }
    
        public static void addJob(String jobClassName, String jobGroupName, String cronExpression)throws Exception{
    
            // 通过SchedulerFactory获取一个调度器实例  
            SchedulerFactory sf = new StdSchedulerFactory();      
    
            Scheduler sched = sf.getScheduler();  
    
            // 启动调度器  
            sched.start(); 
    
            //构建job信息
            JobDetail jobDetail = JobBuilder.newJob(getClass(jobClassName).getClass()).withIdentity(jobClassName, jobGroupName).build();
    
            //表达式调度构建器(即任务执行的时间)
            CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(cronExpression);
    
            //按新的cronExpression表达式构建一个新的trigger
            CronTrigger trigger = TriggerBuilder.newTrigger().withIdentity(jobClassName, jobGroupName)
                .withSchedule(scheduleBuilder).build();
    
            try {
                sched.scheduleJob(jobDetail, trigger);
    
            } catch (SchedulerException e) {
                System.out.println("创建定时任务失败"+e);
                throw new Exception("创建定时任务失败");
            }
        }
    
    
        @PostMapping(value="/pausejob")
        public void pausejob(@RequestParam(value="jobClassName")String jobClassName, @RequestParam(value="jobGroupName")String jobGroupName) throws Exception
        {           
            jobPause(jobClassName, jobGroupName);
        }
    
        public static void jobPause(String jobClassName, String jobGroupName) throws Exception
        {
            // 通过SchedulerFactory获取一个调度器实例  
            SchedulerFactory sf = new StdSchedulerFactory();               
            Scheduler sched = sf.getScheduler();    
            sched.pauseJob(JobKey.jobKey(jobClassName, jobGroupName));
        }
    
    
        @PostMapping(value="/resumejob")
        public void resumejob(@RequestParam(value="jobClassName")String jobClassName, @RequestParam(value="jobGroupName")String jobGroupName) throws Exception
        {           
            jobresume(jobClassName, jobGroupName);
        }
    
        public static void jobresume(String jobClassName, String jobGroupName) throws Exception
        {
             // 通过SchedulerFactory获取一个调度器实例  
            SchedulerFactory sf = new StdSchedulerFactory();               
            Scheduler sched = sf.getScheduler(); 
            sched.resumeJob(JobKey.jobKey(jobClassName, jobGroupName));
        }
    
    
        @PostMapping(value="/reschedulejob")
        public void rescheduleJob(@RequestParam(value="jobClassName")String jobClassName, 
                @RequestParam(value="jobGroupName")String jobGroupName,
                @RequestParam(value="cronExpression")String cronExpression) throws Exception
        {           
            jobreschedule(jobClassName, jobGroupName, cronExpression);
        }
    
        public static void jobreschedule(String jobClassName, String jobGroupName, String cronExpression) throws Exception
        {               
            try {
                SchedulerFactory schedulerFactory = new StdSchedulerFactory();
                Scheduler scheduler = schedulerFactory.getScheduler();
                TriggerKey triggerKey = TriggerKey.triggerKey(jobClassName, jobGroupName);
                // 表达式调度构建器
                CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(cronExpression);
    
                CronTrigger trigger = (CronTrigger) scheduler.getTrigger(triggerKey);
    
                // 按新的cronExpression表达式重新构建trigger
                trigger = trigger.getTriggerBuilder().withIdentity(triggerKey).withSchedule(scheduleBuilder).build();
    
                // 按新的trigger重新设置job执行
                scheduler.rescheduleJob(triggerKey, trigger);
            } catch (SchedulerException e) {
                System.out.println("更新定时任务失败"+e);
                throw new Exception("更新定时任务失败");
            }
        }
    
    
        @PostMapping(value="/deletejob")
        public void deletejob(@RequestParam(value="jobClassName")String jobClassName, @RequestParam(value="jobGroupName")String jobGroupName) throws Exception
        {           
            jobdelete(jobClassName, jobGroupName);
        }
    
        public static void jobdelete(String jobClassName, String jobGroupName) throws Exception
        {       
            // 通过SchedulerFactory获取一个调度器实例  
            SchedulerFactory sf = new StdSchedulerFactory();               
            Scheduler sched = sf.getScheduler(); 
            sched.pauseTrigger(TriggerKey.triggerKey(jobClassName, jobGroupName));
            sched.unscheduleJob(TriggerKey.triggerKey(jobClassName, jobGroupName));
            sched.deleteJob(JobKey.jobKey(jobClassName, jobGroupName));             
        }
    
    
        @GetMapping(value="/queryjob")
        public Map<String, Object> queryjob(@RequestParam(value="pageNum")Integer pageNum, @RequestParam(value="pageSize")Integer pageSize) 
        {           
            PageInfo<JobAndTrigger> jobAndTrigger = iJobAndTriggerService.getJobAndTriggerDetails(pageNum, pageSize);
            Map<String, Object> map = new HashMap<String, Object>();
            map.put("JobAndTrigger", jobAndTrigger);
            map.put("number", jobAndTrigger.getTotal());
            return map;
        }
    
        public static BaseJob getClass(String classname) throws Exception 
        {
            Class<?> class1 = Class.forName(classname);
            return (BaseJob)class1.newInstance();
        }
    
    
    }

注意最下面的这个方法，根据类名称，通过反射得到该类，然后创建一个BaseJob的实例。由于NewJob和HelloJob都实现了BaseJob，所以这里不需要我们手动去判断。这里涉及到了一些java多态调用的机制，篇幅原因不多做解释。

其他的部分，例如service层，dao层以及mapper，与上一篇文章几乎完全相同。我们可以看一下现在的工程结构：

![这里写图片描述][SouthEast 1]

我们可以看到static下的JobManager.html，这个是前端的一个简单的管理页面。Spring Boot的web工程中，静态页面可以放在static目录下。这里贴一下代码，与之前几乎没区别：

唯一的区别是这里所用到的所有vue插件和ElementUI插件都是通过CDN方式引入，方便读者下载之后直接运行。需要**注意**的是，在添加新的任务的时候，填写任务名称时一定要把这个Job类的完整路径输入进来。例如

否则会报找不到该类的错误。对于Cron表达式，可以去[在线Cron表达式生成器][Cron]根据自己的需求自动生成。程序的截图如下

# 工程地址 #

这个工程已上传至[我的github][github]。如果你按上一篇文章的方法已经在mysql数据库中用脚本建立了数据表，那么下载这个工程之后只需要把application.yml和quartz.properties中对数据库连接的配置修改成你自己的数据库配置即可。

## 运行方法 ##

Spring Boot工程已经集成了服务器。右键点击DemoApplication.java -> Run As -> Java Application即可运行工程。默认端口为8080，启动后在浏览器地址栏输入[http://localhost:8080/JobManager.html][http_localhost_8080_JobManager.html]就可以看到效果。
