春季批处理:如果在特定时间未完成,请重试作业 [英] Spring batch: Retry job if does not complete in particular time
问题描述
我正在使用将RetryTemplate
与SimpleRetryPolicy
结合使用的Spring批处理应用程序.
I am working on a Spring batch application where I have used RetryTemplate
with SimpleRetryPolicy
.
在此应用程序中,ItemProcessor
通常需要30-35分钟才能完成特定任务.但是有时,完成同一任务需要不到2个小时的时间.
In this application, ItemProcessor
usually takes 30-35 mins to complete a particular task. But sometimes, it takes from than 2hrs to complete that same task.
如果分配的任务没有在给定的时间内完成,是否可以重试我的ItemProcessor
?
Is there a way to retry my ItemProcessor
, if the assigned task is not completed within given time period?
我正在寻找一些Java/Spring内置功能,而不是编写自己的超时逻辑.
I am looking for some Java/Spring in-build functionality instead of writing my own timeout logic.
推荐答案
您可以为给定步骤定义transactional-attributes
. ( https://docs.spring.io/spring-batch/trunk/reference/htmlsingle/#transactionAttributes )
You can define transactional-attributes
to a given step. (https://docs.spring.io/spring-batch/trunk/reference/htmlsingle/#transactionAttributes)
事务属性可用于控制隔离,传播和超时设置.
Transaction attributes can be used to control the isolation, propagation, and timeout settings.
<step id="step1">
<tasklet>
<chunk reader="itemReader" writer="itemWriter" commit-interval="2"/>
<transaction-attributes isolation="DEFAULT"
propagation="REQUIRED"
timeout="30"/>
</tasklet>
</step>
