Spring 将失败的步骤添加到执行上下文的步骤侦听器
我想知道是否有一种方法可以使用afterStep并创建一个步骤执行侦听器来检查作业中的任何失败步骤,并将该步骤名称和退出状态添加到执行上下文中 虽然我的作业中的一个步骤失败,但我们返回Spring 将失败的步骤添加到执行上下文的步骤侦听器,spring,spring-batch,listener,Spring,Spring Batch,Listener,我想知道是否有一种方法可以使用afterStep并创建一个步骤执行侦听器来检查作业中的任何失败步骤,并将该步骤名称和退出状态添加到执行上下文中 虽然我的作业中的一个步骤失败,但我们返回RepeatStatus.FINISHED。我创建了一个电子邮件报告,并希望包括失败的步骤名称和状态。这是我的电子邮件任务 public class SendEmailTasklet implements Tasklet { final static Logger LOGGER = LoggerFacto

。我创建了一个电子邮件报告,并希望包括失败的步骤名称和状态。这是我的电子邮件任务
public class SendEmailTasklet implements Tasklet {
final static Logger LOGGER = LoggerFactory.getLogger(SendEmailTasklet.class);
@Autowired
public JavaMailSender emailSender;
@Override
public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) throws Exception {
JobParameters jobParameters = chunkContext.getStepContext().getStepExecution().getJobParameters();
ExecutionContext ec = chunkContext.getStepContext().getStepExecution().getJobExecution().getExecutionContext();
//obtain email address and program name from the execution context
String programName = ec.getString(AbstractSetupTasklet.BATCH_PROGRAM_NAME);
String toEmail = jobParameters.getString("TOEMAIL");
if(StringUtils.isEmpty(toEmail)) {
LOGGER.info("No email address associated with the user. Job status is " + programStatus);
return RepeatStatus.FINISHED;
}
else {
//construct the message
SimpleMailMessage message = new SimpleMailMessage();
message.setTo(toEmail);
message.setSubject("Batch Reporting");
message.setText("The batch program " + programName + " has exited with a status of " + programStatus);
emailSender.send(message);
LOGGER.info("Email succesfully sent to user at " + toEmail);
return RepeatStatus.FINISHED;
}
}
}
从上面的代码中可以看出,我想返回程序状态
,或者说“作业在X步骤失败,状态为X”
编辑:
对于任何想知道的人,我将在下面发布我完成的代码。我提出了一种新方法来构造电子邮件消息,以减少重复代码
public class SendEmailTasklet implements Tasklet {
final static Logger LOGGER = LoggerFactory.getLogger(SendEmailTasklet.class);
@Autowired
public JavaMailSender emailSender;
@Override
public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) throws Exception {
//Get the job info
JobParameters jobParameters = chunkContext.getStepContext().getStepExecution().getJobParameters();
ExecutionContext ec = chunkContext.getStepContext().getStepExecution().getJobExecution().getExecutionContext();
//Get the step info
JobExecution jobExecutions = chunkContext.getStepContext().getStepExecution().getJobExecution();
Collection<StepExecution> stepExecution = jobExecutions.getStepExecutions();
//Get the email address and program name
String programName = ec.getString(AbstractSetupTasklet.BATCH_PROGRAM_NAME);
String toEmail = jobParameters.getString("TOEMAIL");
//If no email address exists, do not send the email.
if(StringUtils.isEmpty(toEmail)) {
LOGGER.info("No email address associated with the user.");
return RepeatStatus.FINISHED;
}
else {
//Check for the first failed step
for (StepExecution step : stepExecution) {
if(step.getExitStatus().equals(ExitStatus.FAILED)) {
String failedStep = step.getStepName();
sendBatchReportEmail(toEmail, programName, failedStep);
LOGGER.info(programName + " has failed on the step " + failedStep);
break;
}
}
sendBatchReportEmail(toEmail, programName, null);
LOGGER.info("No email address associated with the user.");
return RepeatStatus.FINISHED;
}
}
public void sendBatchReportEmail(String toEmail, String programName, String stepName) {
if(Utils.isEmpty(stepName)) {
//construct the message
SimpleMailMessage message = new SimpleMailMessage();
message.setTo(toEmail);
message.setSubject("Batch Reporting");
message.setText("The batch program " + programName + " has completed.");
emailSender.send(message);

您可以通过chunkContext.getStepContext().getstepcexecution().getJobExecution()
从区块上下文访问作业执行
一旦执行了作业,就可以使用jobsecution.getStepExecutions()
获取所有步骤执行,并对它们进行迭代以检查最后失败的步骤
上次失败的StepExecution为您提供了创建消息所需的步骤名称、退出代码和描述,然后将其添加到作业执行上下文中
希望这有帮助。太棒了,非常感谢。我来看看我能用它做些什么我已经用下面的代码获得了所有的步骤执行
Collection stepExecution=jobExecutions.getStepExecutions()
您认为检查最后一步失败的最佳方法是什么?您可以选择第一步,即ExitStatus=failed
。
