如何从命令行停止Spring-boot批处理作业？

Question

我能够通过命令行使用commandlinerunner成功地启动springboot-batch作业。

@Component
public class CommandLineAppStartupRunner implements CommandLineRunner {
    @Autowired
    ApplicationContext context;
    @Override
    public void run(String...args) throws Exception {
        JobLauncher jobLauncher = context.getBean(JobLauncher.class);
        Job myJob = context.getBean(args[0], Job.class);
        JobParameters jobParameters = new JobParametersBuilder().addLong("time", System.currentTimeMillis()).toJobParameters();
        try {
            jobLauncher.run(myJob, jobParameters);
        } catch (JobExecutionAlreadyRunningException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (JobRestartException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (JobInstanceAlreadyCompleteException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (JobParametersInvalidException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

java -jar <jarName> <jobName>

Spring batch默认支持通过arg停止作业的选项，请查看下面的文档：

https://docs.spring.io/spring-batch/trunk/apidocs/org/springframework/batch/core/launing/support/commandlinejobrunner.html

jobPath <options> jobIdentifier (jobParameters)*
The command line options are as follows

jobPath: the xml application context containing a Job

-stop: (optional) to stop a running execution
jobIdentifier: the name of the job or the id of a job execution (for -stop, -abandon or -restart).

jobParameters: 0 to many parameters that will be used to launch a job specified in the form of key=value pairs.
