说明：使用spring-boot-starter-quartz实现定时任务处理，并将定时任务持久化到mysql数据库，数据源采用druid-spring-boot-starter。
1.添加Maven依赖
<dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-quartz</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>cn.hutool</groupId> <artifactId>hutool-all</artifactId> <version>5.5.7</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> <!-- https://mvnrepository.com/artifact/com.alibaba/druid-spring-boot-starter --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid-spring-boot-starter</artifactId> <version>1.2.4</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-jdbc --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies>
2.application.properties配置文件
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource spring.datasource.driver-class-name=com.mysql.jdbc.Driver spring.datasource.druid.business.url=jdbc:mysql://localhost:3306/test?setUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false spring.datasource.druid.business.username=root spring.datasource.druid.business.password=mysql spring.datasource.druid.quartz.url=jdbc:mysql://localhost:3306/test?setUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false spring.datasource.druid.quartz.username=root spring.datasource.druid.quartz.password=mysql spring.datasource.druid.initialSize=5 spring.datasource.druid.minIdle=5 spring.datasource.druid.maxActive=30 spring.datasource.druid.maxWait=600000 spring.datasource.druid.timeBetweenEvictionRunsMillis=60000 spring.datasource.druid.minEvictableIdleTimeMillis=300000 spring.datasource.druid.validationQuery=SELECT 1 FROM DUAL spring.datasource.druid.testWhileIdle=true spring.datasource.druid.testOnBorrow=false spring.datasource.druid.testOnReturn=false spring.datasource.druid.poolPreparedStatements=true spring.quartz.job-store-type=jdbc spring.quartz.jdbc.initialize-schema=never spring.quartz.properties.org.quartz.scheduler.instanceName=FpclScheduler spring.quartz.properties.org.quartz.scheduler.instanceId=AUTO spring.quartz.properties.org.quartz.jobStore.class=org.quartz.impl.jdbcjobstore.JobStoreTX spring.quartz.properties.org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.StdJDBCDelegate spring.quartz.properties.org.quartz.jobStore.useProperties=false spring.quartz.properties.org.quartz.jobStore.tablePrefix=QRTZ_ spring.quartz.properties.org.quartz.jobStore.isClustered=false spring.quartz.properties.org.quartz.threadPool.class=org.quartz.simpl.SimpleThreadPool spring.quartz.properties.org.quartz.threadPool.threadCount=100 spring.quartz.properties.org.quartz.threadPool.threadPriority=5 spring.quartz.properties.org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread=true
3.数据源配置DataSourceConfig.java
@Configuration public class DataSourceConfig { @Primary @Bean(name = "dbDataSource") @ConfigurationProperties(prefix = "spring.datasource.druid.business") public DruidDataSource druidDataSource() { return new DruidDataSource(); } @Bean @QuartzDataSource @ConfigurationProperties(prefix = "spring.datasource.druid.quartz") public DataSource quartzDataSource(){ return new DruidDataSource(); } }
4.定时任务DealZzsptfpJob.java
@Component @DisallowConcurrentExecution public class DealZzsptfpJob extends QuartzJobBean { @Override protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException { StaticLog.info("任务开始执行"); try { Thread.sleep(2000); } catch (InterruptedException e) { e.printStackTrace(); } StaticLog.info("任务执行完成"); } }
5.任务管理测试JobController.java，实现任务的创建以及修改功能
@RestController @RequestMapping( value = "/jobs", produces = "application/json;charset=utf-8", headers = "Accept=application/json" ) public class JobController { @Autowired private Scheduler scheduler; /** * 创建定时任务并启动执行 * @param params * @return */ @PostMapping("/create") public Map<String,Object> createJob(@RequestBody Map<String,String> params){ Map<String,Object> result = new HashMap<>(); int code = 0; String msg = ""; CronScheduleBuilder csb = CronScheduleBuilder.cronSchedule(params.get("cron")); String jobName= params.get("jobName"); String jobGroupName = params.get("jobGroupName"); TriggerKey triggerKey = TriggerKey.triggerKey(jobName, jobGroupName); Trigger trigger = null; try { trigger = scheduler.getTrigger(triggerKey); if(trigger==null){ JobDetail jobDetail = JobBuilder.newJob(DealZzsptfpJob.class).withIdentity(jobName, jobGroupName).build(); trigger = TriggerBuilder.newTrigger().withIdentity(triggerKey).withSchedule(csb).build(); scheduler.scheduleJob(jobDetail, trigger); if(scheduler.isShutdown()){ scheduler.start(); } msg = "任务创建成功，jobName:"+jobName+",jobGroupName:"+jobGroupName; }else{ code = 1; msg = "任务已经存在，jobName:"+jobName+",jobGroupName:"+jobGroupName; } } catch (SchedulerException e) { e.printStackTrace(); code = 2; msg = e.getMessage(); } result.put("code", code); result.put("msg", msg); return result; } /** * 修改任务的触发时机 * @param params * @return */ @PostMapping("/edit") public Map<String,Object> editJob(@RequestBody Map<String,String> params){ Map<String,Object> result = new HashMap<>(); int code = 0; String msg = ""; String cron = params.get("cron"); String jobName= params.get("jobName"); String jobGroupName = params.get("jobGroupName"); TriggerKey triggerKey = TriggerKey.triggerKey(jobName, jobGroupName); try { Trigger trigger = scheduler.getTrigger(triggerKey); if (trigger != null) { TriggerBuilder<Trigger> triggerBuilder = TriggerBuilder.newTrigger(); triggerBuilder.withIdentity(triggerKey); triggerBuilder.startNow(); triggerBuilder.withSchedule(CronScheduleBuilder.cronSchedule(cron)); CronTrigger cronTrigger = (CronTrigger) triggerBuilder.build(); scheduler.rescheduleJob(triggerKey, cronTrigger); msg = "任务修改成功，jobName:"+jobName+",jobGroupName:"+jobGroupName; }else{ code = 1; msg = "任务不存在，jobName:"+jobName+",jobGroupName:"+jobGroupName; } } catch (SchedulerException e) { e.printStackTrace(); code = 2; msg = e.getMessage(); } result.put("code", code); result.put("msg", msg); return result; } }
6.测试
（1）创建任务
（2）修改任务克隆表达式
7：quartz相关建表脚本

This is the script from Quartz to create the tables in a MySQL database, modified to use INNODB instead of MYISAM.
