具体任务

public class GenerateReportJob implements Job {
    @Override
    public void execute(JobExecutionContext context) throws JobExecutionException {
        System.out.println("Generating report...");
        // 报表生成逻辑
    }
}

配置

@Configuration
public class QuartzConfig {

    @Bean
    public JobDetail generateReportJobDetail() {
        return JobBuilder.newJob(GenerateReportJob.class)
                .withIdentity("generateReportJob")
                .storeDurably()
                .build();
    }

    @Bean
    public Trigger generateReportJobTrigger() {
        CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule("* * * * * ?");
        return TriggerBuilder.newTrigger()
                .forJob(generateReportJobDetail())
                .withIdentity("generateReportJobTrigger")
                .withSchedule(scheduleBuilder)
