NoSuchJobException when running a job programmatically in Spring Batch

Here is what I had to do to fix my problem:

Add the following Bean to the BatchConfiguration :

@Bean
public JobRegistryBeanPostProcessor jobRegistryBeanPostProcessor(JobRegistry jobRegistry) {
    JobRegistryBeanPostProcessor jobRegistryBeanPostProcessor = new JobRegistryBeanPostProcessor();
    jobRegistryBeanPostProcessor.setJobRegistry(jobRegistry);
    return jobRegistryBeanPostProcessor;
}

Replace the JobLocator by an @Autowired JobRegistry, and use the @Autowired JobLauncher instead of creating one. My run method now have the following code :

@Autowired
private JobRegistry jobRegistry;

@Autowired
private JobLauncher launcher;

public String runBatch() {
    try {
        Job job = jobRegistry.getJob("importCityFileJob");
        JobParameters jobParameters = new JobParameters();
        launcher.run(job, jobParameters);
    } catch (Exception e) {
        e.printStackTrace();
        System.out.println("Something went wrong");
    }
    return "OK";
}

I hope it will help someone.

A JobRegistry won't populate itself. In your example, you're creating a new instance, then trying to get the job from it without having registered it in the first place. Typically, the JobRegistry is configured as a bean along with an AutomaticJobRegistrar that will load all jobs into the registrar on startup. That doesn't mean they will be executed, just registered so they can be located later.

If you're using Java configuration, this should happen automatically using the @EnableBatchProcessing annotation. With that annotation, you'd just inject the provided JobRegistry and the jobs should already be there.

You can read more about the @EnableBatchProcessing in the documentation here: http://docs.spring.io/spring-batch/apidocs/org/springframework/batch/core/configuration/annotation/EnableBatchProcessing.html
