Setting ExecutionContext Before Launch

[acalbazana]

Hello,

Quick question... What is the best way to set a job's execution context before using a launcher to launch a job?

Before I go and extend JobLauncher, I'd like to know if it is possible to set the execution context for a job before launching it through a JobLauncher. I am using SimpleJobLauncher right now to run jobs, but I need to conditionally park a value in execution context before I run it.

// create execution
JobExecution jobExecution = jobRepository.createJobExecution(job.getName(), jobParameters);			

// set context values...

// update execution
this.jobRepository.update(jobExecution);

// run job
fuzzy - run job given an execution?!

Thanks,

Alejandro

One easy way is to put a @BeforeJob method in a class and have that method dump values to the ExecutionContext:

@BeforeJob
public void dumpValues(JobExecution je){
    je.getExecutionContext().put("key", value);
}

Then just wire this listener into your job.

The values inserted can come from anywhere. They can be hard-coded or you could have them be configurable from the XML context.
