批处理作业由于JobExecutionAlreadyRunningException而失败：此作业的作业执行已在运行

Question

如何从主要方法停止批处理作业？我正在从我的方法运行批处理作业，现在它给了我以下错误。对如何杀死和阻止它有帮助吗？

A job execution for this job is already running: JobInstance: id=18380, version=0, Job=[myFileGenerationJob]
org.springframework.batch.core.repository.JobExecutionAlreadyRunningException: A job execution for this job is already running: JobInstance: id=18380, version=0, Job=[myFileGenerationJob]
Done

我正在使用以下代码-

public class CustomerFileGenerationApp {

    public static void main(String[] args) {
        PropertyConfigurator.configure("src/main/resources/log4j.properties");
        String[] springConfig = { "../META-INF/spring/customer-file-generation-job.xml"};

        ApplicationContext context = new FileSystemXmlApplicationContext(springConfig);

        JobLauncher jobLauncher = (JobLauncher) context.getBean("jobLauncher");
        Job job = (Job) context.getBean("customerFileGenerationJob");

        JobParameters jobParameters = new JobParametersBuilder().addString("runMode", "ABCD").toJobParameters();

        try {
            JobExecution execution = jobLauncher.run(job, jobParameters);
            System.out.println("Exit Status : " + execution.getStatus());
        } catch (Exception e) {
            System.out.println(e.getMessage());
            e.printStackTrace();
        }

        System.out.println("Done");
    }

}
