问题描述
我正在将基于Spring Batch XML的应用程序转换为Spring Boot批注.在我的XML文件中,我不确定如何将那些jobParameters和执行上下文传递给tasklet吗?
I am converting Spring Batch XML based application into the Spring Boot annotations. In my XML file, I am not sure how to pass those jobParameters and execution context to tasklet ?

</batch:step>

<bean id="contextTasklet" class="com.XXX.batch.tasklet.ContextTasklet" scope="step">
<property name="runMode" value="#{jobParameters['runMode']}" />
<property name="executionContext" value="#{stepExecution.jobExecution.executionContext}" />
</bean>
</beans>
ContextTasklet.java
@Data
@Configuration
@StepScope
public class ContextTasklet implements Tasklet{
private String runMode;
private ExecutionContext executionContext;
@Override
public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) throws Exception {
chunkContext.getStepContext().getStepExecution().getJobExecution().getExecutionContext().put("mode",
runMode);
return RepeatStatus.FINISHED;
}
}
推荐答案
您可以使用@Value
批注注入作业参数和执行上下文值:
You can use the @Value
annotation to inject job parameters and execution context values:
@Data
@Configuration
@StepScope
public class ContextTasklet implements Tasklet{
@Value("#{jobParameters['runMode']}")
private String runMode;
@Value("#{stepExecution.jobExecution.executionContext}")
private ExecutionContext executionContext;
@Override
public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) throws Exception {
chunkContext.getStepContext().getStepExecution().getJobExecution().getExecutionContext().put("mode",
runMode);
return RepeatStatus.FINISHED;
}
}
