Question

我是春季批次新手，对暂停/恢复有一些疑问。阅读弹簧批文档后，似乎没有任何内置的暂停或恢复功能。但是，我从主站点找到了这个用例：

http://docs.spring.io/spring-batch/2.0.x/cases/pause.html

没有提供样品代码，或者我可以在哪里找到这些样品？

在Spring批处理中，我了解内置了一个停止和重启功能。我可以用它作为暂停和恢复的形式吗？或者还有另一种更好的方法吗？

Answer 1

停止/重启基本上是暂停和恢复。它允许您以编程方式停止正在运行的作业并从中断处继续。

Answer 2

为此使用作业运算符，它是提供诸如stop，restart，getStatus之类的功能的基本接口。

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
