# 使用 Spring `TaskScheduler`進行 Spring Batch 作業調度 > 原文： [https://howtodoinjava.com/spring-batch/job-scheduler-example/](https://howtodoinjava.com/spring-batch/job-scheduler-example/) 在企業應用程序中，您將需要將 **cron 表達式**傳遞給 Spring `TaskScheduler`，在固定的時間表上定期執行 Spring Batch 作業。 在此示例中，我們將使用 spring 的內置調度功能執行[示例 Spring Batch 作業](https://howtodoinjava.com/spring-batch/java-config-multiple-steps/)。 ## 配置批處理作業調度程序 要配置，批處理作業調度分兩個步驟完成： 1. 啟用帶有[`@EnableScheduling`](https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/scheduling/annotation/EnableScheduling.html)注解的調度。 2. 創建帶有[`@Scheduled`](https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/scheduling/annotation/Scheduled.html)注解的方法，并使用 cron 作業提供重復詳細信息。 在此方法內添加作業執行邏輯。 `Cron scheduling on spring batch job` ```java package com.howtodoinjava.demo; import org.springframework.batch.core.Job; import org.springframework.batch.core.JobParameters; import org.springframework.batch.core.JobParametersBuilder; import org.springframework.batch.core.launch.JobLauncher; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.scheduling.annotation.EnableScheduling; import org.springframework.scheduling.annotation.Scheduled; @SpringBootApplication @EnableScheduling public class App { @Autowired JobLauncher jobLauncher; @Autowired Job job; public static void main(String[] args) { SpringApplication.run(App.class, args); } @Scheduled(cron = "0 */1 * * * ?") public void perform() throws Exception { JobParameters params = new JobParametersBuilder() .addString("JobID", String.valueOf(System.currentTimeMillis())) .toJobParameters(); jobLauncher.run(job, params); } } ``` 批處理作業將在應用程序啟動后每隔一分鐘運行一次。 > 要引用作業和任務源代碼，請閱讀[ Spring batch Java 配置示例](https://howtodoinjava.com/spring-batch/java-config-multiple-steps/)。 ## 示例 現在，如果您運行該應用程序并驗證日志，您將看到該作業每分鐘都在運行。 `Console` ```java 2018-07-04 15:57:00.073 INFO 7320 --- [pool-1-thread-1] o.s.b.c.l.support.SimpleJobLauncher : Job: [SimpleJob: [name=demoJob]] launched with the following parameters: [{JobID=1530700020003}] 2018-07-04 15:57:00.097 INFO 7320 --- [pool-1-thread-1] o.s.batch.core.job.SimpleStepHandler : Executing step: [stepOne] MyTaskOne start..
