# SpringBoot集成Quartz实现定时任务 #

## 工程概述 ##

springboot-quartz是基于SpringBoot实现的定时任务工程

## 实现步骤分析 ##

### 引入相关依赖 ###

<dependencies>
    
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-quartz</artifactId>
        </dependency>
    
    </dependencies>

### 创建springboot-quartz启动类 ###

import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication
    public class Application { 
    
        public static void main(String[] args) throws Exception {
            SpringApplication.run(Application.class, args);
        }
    
    }

### 创建定时任务业务逻辑实现类 ###

import org.quartz.DisallowConcurrentExecution;
    import org.quartz.JobExecutionContext;
    import org.quartz.JobExecutionException;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.scheduling.quartz.QuartzJobBean;
    
    /** * 定时任务业务处理类 * 该类需要继承QuartzJobBean类并重写executeInternal方法来实现定时任务的具体逻辑 * @author shanglishuai * */
    @DisallowConcurrentExecution // 用于标记定时任务禁止并发执行
    public class QuartzTaskService extends QuartzJobBean { 
    
        private static final Logger log = LoggerFactory.getLogger(QuartzTaskService.class);
    
        /** * 该方法用于实现定时任务的具体逻辑 */
        @Override
        protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
            log.info("------------- 定时任务开始 -------------");
            try {
                // 休眠5秒钟，模拟定时任务执行过程
                Thread.sleep(5000L);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            log.info("------------- 定时任务结束 -------------");
        }
    
    }

`@DisallowConcurrentExecution`:用于标记定时任务禁止并发执行,可根据具体业务场景选择是否启用

### 创建Quartz配置类 ###

import org.quartz.CronScheduleBuilder;
    import org.quartz.JobBuilder;
    import org.quartz.JobDetail;
    import org.quartz.Trigger;
    import org.quartz.TriggerBuilder;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    import cn.tyrone.springboot.quartz.service.QuartzTaskService;
    
    /** * 该类是配置类，用于Quartz配置所需要 * @author shanglishuai * */
    @Configuration 
    public class QuartzConfig { 
    
        /** * JobDetail 用于指定定时任务具体的类 */
        @Bean
        public JobDetail quartzTaskServiceJobDetail() {
            return JobBuilder.newJob(QuartzTaskService.class).withIdentity("quartzTaskService").storeDurably().build();
        }
    
        /** * Trigger 用于指定定时任务触发的机制 */
        @Bean
        public Trigger quartzTaskServiceTrigger() {
            CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule("*/5 * * * * ?");
            return TriggerBuilder.newTrigger().forJob(quartzTaskServiceJobDetail())
                    .withIdentity("quartzTaskService")
                    .withSchedule(scheduleBuilder)
                    .build();
        }
    }
