有同样的问题在这里问 -

为此使用作业运算符，它是提供停止、重新启动、getStatus 等功能的基本接口

public interface JobOperator {

List<Long> getExecutions(long instanceId) throws NoSuchJobInstanceException;

List<Long> getJobInstances(String jobName, int start, int count)
      throws NoSuchJobException;

Set<Long> getRunningExecutions(String jobName) throws NoSuchJobException;

String getParameters(long executionId) throws NoSuchJobExecutionException;

Long start(String jobName, String parameters)
      throws NoSuchJobException, JobInstanceAlreadyExistsException;

Long restart(long executionId)
      throws JobInstanceAlreadyCompleteException, NoSuchJobExecutionException,
              NoSuchJobException, JobRestartException;

Long startNextInstance(String jobName)
      throws NoSuchJobException, JobParametersNotFoundException, JobRestartException,
             JobExecutionAlreadyRunningException, JobInstanceAlreadyCompleteException;

boolean stop(long executionId)
      throws NoSuchJobExecutionException, JobExecutionNotRunningException;

String getSummary(long executionId) throws NoSuchJobExecutionException;

Map<Long, String> getStepExecutionSummaries(long executionId)
      throws NoSuchJobExecutionException;

Set<String> getJobNames();

}

这是一个例子
