我只需要显示消息：“作业实例已经存在且已完成......”
我正在使用Spring与Spring批量集成。
如何捕获此异常并创建自定义消息？
IntegrationConfig.class
/**
* Transform File Message to JobRequest
*
* @return FileMessageToJobRequest
*/
@Bean
public FileMessageToJobRequest fileMessageToJobRequest() {
FileMessageToJobRequest transformer = new FileMessageToJobRequest();
transformer.setJob(sampleJob);
transformer.setFileParameterName("file_path");
return transformer;
}
/**
* Send a JobLaunching to Spring Batch and starting the batch process
*
* @return JobLaunchingMessageHandler
* @throws FileAlreadyExistException
*/
@Bean
@ServiceActivator(inputChannel = "startJob", outputChannel = "tranformMessage")
public JobLaunchingMessageHandler jobLaunchingMessageHandler() {
return new JobLaunchingMessageHandler(jobLauncher);
}

您在问题中显示的日志：
ERROR (task-scheduler-1) [LoggingHandler(handleMessageInternal:192)] org.springframework.messaging.MessageHandlingException: nested exception is org.springframework.batch.core.repository.JobInstanceAlreadyCompleteException:
我是全球errorChannel及其默认LoggingHandler订阅者的一部分。
为了达到您的目的，您需要声明具有相同PublishSubscribeChannel名称的errorChannel bean，以覆盖默认情况下Framework提供的名称。
这样提到的LoggingHandler也会出现。因此，您需要将@ServiceActivator LoggingHandler的{{1}}与@Bean属性作为有效负载进行恢复，以提取其原因expression MessageHandlingException已经是请求的JobInstanceAlreadyCompleteException。您可以使其成为条件状态，不会污染应用程序中所有其他异常的标准行为。仅仅因为errorChannel是全球性的。
如果您可以控制此类属性，也可以执行自定义error-channel所述的所有操作，例如在@MessagingGateway级别：https://docs.spring.io/spring-integration/docs/5.0.4.RELEASE/reference/html/messaging-endpoints-chapter.html#gateway-error-handling
