是否有可能找出,如果作业在Spring Batch中重新启动?

我们确实提供了一些Tasklets,但没有spring-batch的重新启动支持,如果重新启动作业,则必须执行我们自己的程序。

在JobRepository,JobOperator,JobExplorer等中找不到任何可能性。

最佳答案

定义具有所需属性的JobExplorer bean

<bean id="jobExplorer"
class="org.springframework.batch.core.explore.support.JobExplorerFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="lobHandler" ref="lobHandler"/>
</bean>


用您的jobName查询

List<JobInstance> jobInstances= jobExplorer.getJobInstances(jobName);

for (JobInstance jobInstance : jobInstances) {
    List<JobExecution> jobExecutions = jobExplorer.getJobExecutions(jobInstance);
    for (JobExecution jobExecution : jobExecutions) {
        if (jobExecution.getExitStatus().equals(ExitStatus.COMPLETED)) {
        //You found a completed job, possible candidate for a restart
        //You may check if the job is restarted comparing jobParameters
        JobParameters jobParameters = jobInstance.getParameters();
        //Check your running job if it has the same jobParameters
        }
     }
}


没有编译这个,但我希望它能给一个想法
