使用 Quartz 運行 Spring Boot 應用程序

Question

我有這個 Spring Boot 應用程序。 使用 Quartz（一個功能豐富的開源作業調度庫，幾乎可以集成到任何 Java 應用程序中）在每月的第 10 天執行作業

@EnableScheduling
@SpringBootApplication
public class IberiaUtilsApplication implements CommandLineRunner {

public static void main(String[] args) {
        SpringApplication app = new SpringApplication(IberiaUtilsApplication.class);
        app.run(args);
    }

    @Override
    public void run(String... args) throws Exception {
    ..
}
}

並在配置包內：

@Configuration
public class JobConfig {

    @Bean
    public JobDetail sampleJobDetail() {
        return JobBuilder.newJob(MonthlyIberiaMetrics.class).withIdentity("iberiaJob")
                .usingJobData("iberiaMetrics", "fleet").storeDurably().build();
    }

    @Bean
    public Trigger sampleJobTrigger() {

        return newTrigger()
                .forJob(sampleJobDetail())
                .withIdentity("iberiaTrigger")
                .withSchedule(cronSchedule("0 0 10 10 * ?"))
                .build();               

    }
}

我運行應用程序。 從命令行，使用mvn spring-boot:run但似乎 Quartz 沒有初始化：

我也嘗試將表達式更改為0 * * * * ? （每分鍾）具有相同的結果

並且還創建了另一個具有相同結果的類：

public class ScheduledTasks1 {


    private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");

    @Scheduled(cron = "0 * * * * ?")
    public void reportCurrentTime() {

        System.out.println("The time is now {}" +
                dateFormat.format(new Date()));

    }
}

供您參考，我有另一個沒有Quartz properties類似應用程序，它工作正常：

@SpringBootApplication
public class IberiaReservationsApplication {

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

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

    @Bean
    public Trigger sampleJobTrigger() {
            return newTrigger()
                .forJob(sampleJobDetail())
                .withIdentity("sampleTrigger")
                .withSchedule(cronSchedule("0 0/2 8-17 * * ?"))
                .build();               

    }
}

Answer 1

您是否考慮過使用Springs自己的調度程序，它很容易配置，而且我一直發現它能很好地工作。 https://spring.io/guides/gs/scheduling-tasks/

Answer 2

您在這里缺少Quartz的各種配置，例如

1. 石英特性
2. SchedulerFactoryBean負責

請按照以下示例進行完整實施：

1. https://chynten.wordpress.com/2016/06/17/quartz-with-databse-and-spring-4/
2. http://www.baeldung.com/spring-quartz-schedule

Answer 3

您可以嘗試https://github.com/mejariamol/quartz-easy 。 該庫簡化了Spring Boot框架中的Crystal Scheduler集成。 我在工作中的一個項目中設置石英調度程序時想到了這一點。

1. 通過設置注釋中存在的適當字段，使用計划的注釋和所需的配置來注釋Job實施。

import com.indusnode.quartz.annotation.Scheduled;
...
@Scheduled(interval="5", intervalType=Scheduled.IntervalType.SEC)
class TestJob implements Job {
    //...
}

2. 將應用程序屬性qe.base-package為項目的基本軟件包名稱，該項目將包含您的所有作業實現。 另外，在組件掃描中將com.indusnode作為值添加到basePackage。
3. 您完成了！ 無需定義工廠，JobDetail，Triggers等。

要使用此庫，請在pom.xml的“ dependencies”部分中包含“ quartz-easy工件。

<dependency>
  <groupId>com.indusnode</groupId>
  <artifactId>quartz-easy</artifactId>
  <version>1.0.0</version>
</dependency>
