java - Spring Batch 作业调度程序

Question

有没有办法为通过 XML 配置的特定 Spring Batch 作业指定调度程序，而无需像这样的 utils RunScheduler 类:https://www.mkyong.com/spring-batch/spring-batch-and-spring-taskscheduler-example/ ？

所以现在我的配置如下所示:

 <batch:job id="testJob" job-repository="jobRepository" parent="jobParent">
        <batch:step id="testStep" allow-start-if-complete="true">
            <batch:tasklet>
                <batch:chunk
                        reader="testReader"
                        processor="testProcessor"
                        writer="jmsWriter">
                </batch:chunk>
            </batch:tasklet>
        </batch:step>
    </batch:job>


 <task:scheduled-tasks>
        <task:scheduled ref="testJobLauncher" method="runJob" cron="0 */5 * * * *"/>
    </task:scheduled-tasks>

    <bean id="testJobLauncher"
          class="com.test.RunScheduler"
          p:job-ref="testJob"
          p:jobLauncher-ref="jobLauncher"
     "/>



@Component
public class RunScheduler {

    private JobLauncher jobLauncher;
    private Job job;

    public void runJob() {
        try {
            String dateParam = new Date().toString();
                JobParameters param = new JobParametersBuilder().addString("date", dateParam).toJobParameters();
                JobExecution execution = jobLauncher.run(job, param);               
        } catch (Exception e) {
            LOGGER.error("Can't start job", e);
            throw new RuntimeException(e);
        }
    }

    public Job getJob() {
        return job;
    }

    public void setJob(Job job) {
        this.job = job;
    }

    public JobLauncher getJobLauncher() {
        return jobLauncher;
    }

    public void setJobLauncher(JobLauncher jobLauncher) {
        this.jobLauncher = jobLauncher;
    }

}

有没有办法不使用 RunScheduler 类而只使用 XML 配置来处理它？<​​/p>

Answer 1

您可以使用 @EnableScheduling 和 cronSequenceGenerator 的功能进行调度和 cron 设置，而不依赖于 util 类。
