您可以在上下文文件規定流量控制,像這樣:在你的Tasklet
<step id="step1">
<tasklet ref="example">
<next on="COMPLETED" to="step2" />
<end on="NO-OP" />
<fail on="*" />
<!--
You generally want to Fail on * to prevent
accidentally doing the wrong thing
-->
</step>
然後,通過實施StepExecutionListener
public class SampleTasklet implements Tasklet, StepExecutionListener {
@Override
public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) throws Exception {
// do something
return RepeatStatus.FINISHED;
}
@Override
public void beforeStep(StepExecution stepExecution) {
// no-op
}
@Override
public ExitStatus afterStep(StepExecution stepExecution) {
//some logic here
boolean condition1 = false;
boolean condition2 = true;
if (condition1) {
return new ExitStatus("COMPLETED");
} else if (condition2) {
return new ExitStatus("FAILED");
}
return new ExitStatus("NO-OP");
}
}
設置退出狀態
