318.6.4. CamelJobExecutionListener
CamelJobExecutionListener
是 org.springframework.batch.core.JobExecutionListener
接口实施,将作业执行事件发送到 Camel 端点。
Spring Batch 生成的 org.springframework.batch.core.JobExecution
实例作为消息正文发送。要区分 before- 和 after-callbacks SPRING_BATCH_JOB_EVENT_TYPE
标头设置为 BEFORE
或 AFTER
值。
以下示例片断会将 Spring Batch 作业执行事件发送到 JMS 队列。
<bean id="camelJobExecutionListener" class="org.apache.camel.component.spring.batch.support.CamelJobExecutionListener"> <constructor-arg ref="producerTemplate"/> <constructor-arg value="jms:batchEventsBus"/> </bean> <batch:job id="myJob"> <batch:step id="step"> <batch:tasklet> <batch:chunk reader="someReader" writer="someWriter" commit-interval="100"/> </batch:tasklet> </batch:step> <batch:listeners> <batch:listener ref="camelJobExecutionListener"/> </batch:listeners> </batch:job>
