How to run job parameters in spring batch with maven in CLI-CodePudding

I have seen several stackoverflow Q&As but none had a job parameter in CLI while using maven.

My parameter is setup like this:

@Value("#{jobParameters.getOrDefault('startTimestamp', null)}") Long startTimestamp

My maven command is like this:

mvn clean spring-boot:run -Dspring.batch.job.names=myJob -Dspring.profiles.active=default,dev -f pom.xml

I am not sure what to add. the following is not working:

-Dspring.batch.job.startTimestamp=1667790578000
-Dspring.batch.job.parameters.startTimestamp=1667790578000

CodePudding user response：

Job parameters are set through the jobLauncher. For example:

JobParameters jobParameters = new JobParametersBuilder()
    .addLong("startTimestamp", 1667790578000L).toJobParameters();

JobExecution execution = jobLauncher.run(job, jobParameters);

If you want to send the parameter as a property, you need to use the @Value annotation to inject your custom property into the bean that launches the job.

CodePudding user response：

From the command line, you can pass job parameters as key/value pairs:

java -jar myjob.jar name=foobar startTimestamp=1667790578000
