谁借莪１个温暖的怀抱￠ 2022-03-17 00:25 246阅读 0赞

## 前言 ##

这里是我真实项目中使用的，个人认为是比较全一点的，如果不足，还希望多多包涵或者补充

## 接2文章的基础上又简单更改了下，变得更加规范 ##

### 1、依赖 ###

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-quartz</artifactId>
            </dependency>
    
            <dependency>
                <groupId>org.quartz-scheduler</groupId>
                <artifactId>quartz-jobs</artifactId>
                <version>2.2.1</version>
            </dependency>
    
            <dependency>
                <groupId>com.alibaba</groupId>
                <artifactId>druid</artifactId>
                <version>1.1.5</version>
            </dependency>

### 2、添加quartz.properties配置 ###

#默认或是自己改名字都行
    org.quartz.scheduler.instanceName=HeaelrJeanQuartzScheduler
    #如果使用集群，instanceId必须唯一，设置成AUTO
    org.quartz.scheduler.instanceId=AUTO
    org.quartz.scheduler.jobFactory.class=org.quartz.simpl.SimpleJobFactory
    org.quartz.scheduler.autoStartup=true
    org.quartz.scheduler.skipUpdateCheck=true
    
    
    
    org.quartz.threadPool.class=org.quartz.simpl.SimpleThreadPool
    org.quartz.threadPool.threadCount=30
    org.quartz.threadPool.threadPriority=5
    
    
    
    #是否使用集群（如果项目只部署到 一台服务器，就不用了）
    rg.quartz.jobStore.isClustered=true
    org.quartz.jobStore.clusterCheckinInterval=20000
    #存储方式使用JobStoreTX，也就是数据库
    org.quartz.jobStore.class=org.quartz.impl.jdbcjobstore.JobStoreTX
    org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.StdJDBCDelegate
    #misfireThreshold是用来设置调度引擎对触发器超时的忍耐时间，简单来说 假设misfireThreshold=6000(单位毫秒)。
    #那么它的意思说当一个触发器超时时间如果大于misfireThreshold的值 就认为这个触发器真正的超时(也叫Misfires)。
    org.quartz.jobStore.misfireThreshold=60000
    #存储的JobDataMaps是否都为String类型
    org.quartz.jobStore.useProperties=true
    
    # 数据源 我们自己配置
    org.quartz.jobStore.dataSource=healerjean
    
    
    
    
    # 数据源使用quartz配置
    #org.quartz.jobStore.tablePrefix = QRTZ_
    #org.quartz.jobStore.dataSource = myDS
    #
    #
    ##配置数据源
    #数据库中quartz表的表名前缀
    #
    #org.quartz.dataSource.myDS.driver = com.mysql.jdbc.Driver
    #org.quartz.dataSource.myDS.URL = jdbc:mysql://localhost:3306/com_hlj_quartz?characterEncoding=utf-8
    #org.quartz.dataSource.myDS.user = root
    #org.quartz.dataSource.myDS.password = 123456
    #org.quartz.dataSource.myDS.maxConnections = 5

### 4、sprinboot配置文件 ###

#### 4.1、主配置文件 ####

spring.application.name=quartz

    healerjean.datasource.driver-class-name=com.mysql.jdbc.Driver
    
    
    
    logging.config=classpath:logback.xml

### 3、数据表采用文章2中的数据库表，这里就不粘贴了 ###

### 4、定时器配置，使用配置文件以及数据源 ###

#### 4.1、单独为定时任务创建了数据源（其实和主数据源是一起的） ####

#### 4.2、添加了定时器监听入口 ####

package com.hlj;
    
    import com.alibaba.druid.pool.DruidDataSource;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.core.io.ClassPathResource;
    import org.springframework.scheduling.quartz.SchedulerFactoryBean;
    import org.springframework.scheduling.quartz.SpringBeanJobFactory;
    
    import javax.sql.DataSource;
    
    /** * 类描述： * 创建人： HealerJean */
    @Configuration
    public class QuartzConfig { 
    
        @Value("${healerjean.datasource.url}")
        private String healerjeanUrl;
        @Value("${healerjean.datasource.username}")
        private String healerjeanname;
        @Value("${healerjean.datasource.password}")
        private String healerjeanPassword;
    
        @Bean
        public SpringBeanJobFactory jobFactory (){ 
            return new SpringBeanJobFactory();
        }
    
        @Bean
        public SchedulerFactoryBean schedulerFactoryBean (SpringBeanJobFactory jobFactory) { 
            SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean();
            schedulerFactoryBean.setDataSource(createAdmore());
            schedulerFactoryBean.setConfigLocation(new ClassPathResource("quartz.properties"));
            schedulerFactoryBean.setJobFactory(jobFactory);
            schedulerFactoryBean.setWaitForJobsToCompleteOnShutdown(true);
            schedulerFactoryBean.setGlobalJobListeners(new com.duodian.admore.quartz.core.event.HealerJeanJobListener());
            schedulerFactoryBean.setOverwriteExistingJobs(true);
            return schedulerFactoryBean;
        }
    
        /** * 单独为定时任务创建一个单独的datasource */
        private DataSource createAdmore(){ 
            DruidDataSource druidDataSource = new DruidDataSource();
            druidDataSource.setUrl(healerjeanUrl);
            druidDataSource.setUsername(healerjeanname);
            druidDataSource.setPassword(healerjeanPassword);
            druidDataSource.setMaxActive(10);
            druidDataSource.setInitialSize(5);
            druidDataSource.setTestWhileIdle(true);
            druidDataSource.setMaxWait(2500);
            druidDataSource.setTimeBetweenEvictionRunsMillis(60000);
            druidDataSource.setMinEvictableIdleTimeMillis(300000);
    
            return druidDataSource;
        }
    
    }

### 5、定时器监听器 ###

在定时器 执行之前，任务取消（一般情况下不执行，博主没遇到过），执行完成（有异常执行完和无异常执行完）

其实有用的，也就是第3个

package com.duodian.admore.quartz.core.event;
    
    import lombok.extern.slf4j.Slf4j;
    import org.quartz.JobExecutionContext;
    import org.quartz.JobExecutionException;
    import org.quartz.JobListener;
    
    /** * 类描述： * 创建人： HealerJean */
    @Slf4j
    public class HealerJeanJobListener implements JobListener { 
    
        private static final String LISTENER_NAME = "healerjean.job.listener";
    
        @Override
        public String getName() { 
            return LISTENER_NAME;
        }
    
        /** * 任务执行之前执行 */
        @Override
        public void jobToBeExecuted(JobExecutionContext jobExecutionContext) { 
            log.info(jobExecutionContext.getJobDetail().getKey() + " to be execute");
        }
    
        /** * * 任务取消 * 这个方法正常情况下不执行,但是如果当TriggerListener中的vetoJobExecution方法返回true时,那么执行这个方法. * 需要注意的是 如果方法(2)执行 那么(1),(3)这个俩个方法不会执行,因为任务被终止了嘛. */
        @Override
        public void jobExecutionVetoed(JobExecutionContext jobExecutionContext) { 
            log.info(jobExecutionContext.getJobDetail().getKey() + " vetoed");
        }
    
        /** 任务执行完成后执行,jobException如果它不为空则说明任务在执行过程中出现了异常 */
        @Override
        public void jobWasExecuted(JobExecutionContext jobExecutionContext, JobExecutionException e) { 
            if (e != null){ 
                String jobName = jobExecutionContext.getJobDetail().getKey().getName();
                String errMsg = e.getMessage();
                log.error(jobExecutionContext.getJobDetail().getKey() + " execute failure");
                log.error(e.getMessage(),e);
            } else { 
                log.info(jobExecutionContext.getJobDetail().getKey() + " execute success");
            }
        }
    }

### 6、定时器任务调度(最核心的) ###

package com.hlj.quartz.core.schedule;
    
    import org.quartz.*;
    import org.quartz.impl.matchers.GroupMatcher;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.stereotype.Component;
    
    import javax.annotation.Resource;
    import java.util.Date;
    import java.util.Set;
    
    /** * HealerJean * quartz job调度核心类 */
    @Component
    public class HealerJeanScheduler { 
    
        private Logger logger = LoggerFactory.getLogger(HealerJeanScheduler.class);
    
        private final static String TRIGGER_PERFIX = "t_";
    
        @Resource
        private Scheduler scheduler;
    
        public <T extends Job> void startJob(String jobId, String cron, Class<T> t, String jobDesc) throws SchedulerException { 
            JobDetail job = JobBuilder.newJob(t).withIdentity(jobId).withDescription(jobDesc).build();
            CronTrigger trigger = TriggerBuilder.newTrigger().withIdentity(TRIGGER_PERFIX + jobId).withSchedule(CronScheduleBuilder.cronSchedule(cron)).build();
            scheduler.scheduleJob(job, trigger);
            logger.info(jobId + " start at " + new Date());
        }
    
        public void resetJob(String jobId,String corn) { 
            try { 
                if (scheduler.checkExists(new JobKey(jobId))){ 
                    JobDetail jobDetail = scheduler.getJobDetail(new JobKey(jobId));
                    logger.info("name:"+jobDetail.getKey().getName());
                    logger.info("group:"+jobDetail.getKey().getGroup());
                    TriggerKey triggerKey = TriggerKey.triggerKey(TRIGGER_PERFIX+jobDetail.getKey().getName(), jobDetail.getKey().getGroup());
                    //获取trigger，即在spring配置文件中定义的 bean id="myTrigger"
                    CronTrigger trigger = (CronTrigger) scheduler.getTrigger(triggerKey);
                    //表达式调度构建器
                    CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(corn);
                    //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);
                    logger.info(jobId + " reset at " + new Date());
                }
            } catch (SchedulerException e) { 
                throw new RuntimeException(e.getMessage(),e);
            }
        }
    
    
        /**** * 暂停任务 */
        public void pauseJob(String jobId) { 
            try { 
                if (scheduler.checkExists(new JobKey(jobId))){ 
                    scheduler.pauseJob(new JobKey(jobId));
                    logger.info(jobId + " pause at " + new Date());
                }
            } catch (SchedulerException e) { 
                throw new RuntimeException(e.getMessage(),e);
            }
        }
    
        /** * 删除任务 * @param jobId */
        public void deleteJob(String jobId) { 
            try { 
                if (scheduler.checkExists(new JobKey(jobId))){ 
                    scheduler.deleteJob(new JobKey(jobId));

            }
        }
    
        /** * 暂停重启 * @param jobId */
        public void resumeJob(String jobId) { 
            try { 
                if (scheduler.checkExists(new JobKey(jobId))){ 
                    scheduler.resumeJob(new JobKey(jobId));
                    logger.info(jobId + " resume at " + new Date());
                }
            } catch (SchedulerException e) { 
                throw new RuntimeException(e.getMessage(),e);
            }
        }
    
        /** * 获取所有的任务 的 JobKey * @return */
        public Set<JobKey> currentJobs(){ 
            try { 
                GroupMatcher<JobKey> matcher = GroupMatcher.anyJobGroup();
                return scheduler.getJobKeys(matcher);
            } catch (SchedulerException e) { 
                throw new RuntimeException(e.getMessage(),e);
            }
        }
    
        /** * 获取任务详情 JobDetail * @param jobKey * @return */
        public JobDetail getJobDetail(JobKey jobKey){ 
            try { 
                return scheduler.getJobDetail(jobKey);
            } catch (SchedulerException e) {

                throw new RuntimeException();
            }
        }
    
    }

### 7、添加一个测试任务 ###

package com.hlj.quartz.job;
    
    import org.quartz.*;
    import org.springframework.stereotype.Component;
    
    /** * @Description * @Author HealerJean * @Date 2018/3/23 下午4:19. */
    
    @Component
    public class MyTask implements Job { 
    
        @Override
        public void execute(JobExecutionContext context) throws JobExecutionException { 
    
            try { 
    
                //可以通过context拿到执行当前任务的quartz中的很多信息，如当前是哪个trigger在执行该任务
                CronTrigger trigger = (CronTrigger) context.getTrigger();
    
                TriggerKey triggerKey =trigger.getKey() ;
                String corn = trigger.getCronExpression();
                System.out.println("任务规则 :"+corn);
    
                System.out.println("triggerKey Name:"+triggerKey.getName()); //t_jobId
                System.out.println("triggerKey group:"+triggerKey.getGroup()); //t_jobId
    
                System.out.println("----------------------");
                JobKey jobKey =   context.getJobDetail().getKey() ;
                System.out.println("jobKey getName"+jobKey.getName()); //jobId
                System.out.println("jobKey getGroup"+jobKey.getGroup()); //DEFAULT
    
                Scheduler scheduler =  context.getScheduler();
                System.out.println("scheduler.getCalendarNames()"+scheduler.getCalendarNames());
    
                JobDetail jobDetail = scheduler.getJobDetail(jobKey);
                System.out.println(jobDetail.getClass().toString());
    
    
            }catch (Exception e){ 
                e.printStackTrace();
            }
            System.out.println("执行任务中");
        }
    }

### 8、测试 ###
