springboot quartz的实现代码

以下是一个简单的 Spring Boot 集成 Quartz 的实现代码：

1. 添加 Maven 依赖

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

2. 创建 Quartz 配置类

@Configuration
public class QuartzConfig {

    @Bean
    public JobDetail sampleJobDetail() {
        return JobBuilder.newJob(SampleJob.class).withIdentity("sampleJob")
                .usingJobData("name", "World").storeDurably().build();
    }

    @Bean
    public Trigger sampleJobTrigger() {
        SimpleScheduleBuilder scheduleBuilder = SimpleScheduleBuilder.simpleSchedule()
                .withIntervalInSeconds(10).repeatForever();

        return TriggerBuilder.newTrigger().forJob(sampleJobDetail())
                .withIdentity("sampleTrigger").withSchedule(scheduleBuilder).build();
    }
}

3. 创建 Quartz Job 类

@Component
public class SampleJob implements Job {

    @Override
    public void execute(JobExecutionContext context) throws JobExecutionException {
        String name = context.getJobDetail().getJobDataMap().getString("name");
        System.out.println("Hello " + name + "!");
    }
}

4. 运行定时任务

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Autowired
    private Scheduler scheduler;

    @Autowired
    private Trigger sampleJobTrigger;

    @Autowired
    private JobDetail sampleJobDetail;

    @PostConstruct
    public void init() {
        try {
            scheduler.scheduleJob(sampleJobDetail, sampleJobTrigger);
        } catch (SchedulerException e) {
            e.printStackTrace();
        }
    }
}

这样就可以实现一个简单的 Spring Boot 集成 Quartz 的定时任务了。
