Class JobOperationsController

java.lang.Object

de.codecentric.batch.web.JobOperationsController

@RestController
 @RequestMapping(value="${batch.web.operations.base:/batch/operations}")
public class JobOperationsController
extends Object

Very simple REST-API for starting and stopping jobs and keeping track of its status. Made for script interaction.

The base url can be set via property batch.web.operations.base, its default is /batch/operations. There are four endpoints available:

1. Starting jobs
   {base_url}/jobs/{jobName} / POST
   Optionally you may define job parameters via request param 'jobParameters'. If a JobParametersIncrementer is specified in the job, it is used to increment the parameters.
   On success, it returns the JobExecution's id as a plain string.
   On failure, it returns the message of the Exception as a plain string. There are different failure possibilities:
   • HTTP response code 404 (NOT_FOUND): the job cannot be found, not deployed on this server.
   • HTTP response code 409 (CONFLICT): the JobExecution already exists and is either running or not restartable.
   • HTTP response code 422 (UNPROCESSABLE_ENTITY): the job parameters didn't pass the validator.
   • HTTP response code 500 (INTERNAL_SERVER_ERROR): any other unexpected failure.
2. Retrieving an JobExecution's ExitCode
   {base_url}/jobs/executions/{executionId} / GET
   On success, it returns the ExitCode of the JobExecution specified by the executionId as a plain string.
   On failure, it returns the message of the Exception as a plain string. There are different failure possibilities:
   • HTTP response code 404 (NOT_FOUND): the JobExecution cannot be found.
   • HTTP response code 500 (INTERNAL_SERVER_ERROR): any other unexpected failure.
3. Retrieving a log file for a specific JobExecution
   {base_url}/jobs/executions/{executionId}/log / GET
   On success, it returns the log file belonging to the run of the JobExecution specified by the executionId as a plain string.
   On failure, it returns the message of the Exception as a plain string. There are different failure possibilities:
   • HTTP response code 404 (NOT_FOUND): the log file cannot be found.
   • HTTP response code 500 (INTERNAL_SERVER_ERROR): any other unexpected failure.
4. Stopping jobs
   {base_url}/jobs/executions/{executionId} / DELETE
   On success, it returns true.
   On failure, it returns the message of the Exception as a plain string. There are different failure possibilities:
   • HTTP response code 404 (NOT_FOUND): the JobExecution cannot be found.
   • HTTP response code 409 (CONFLICT): the JobExecution is not running.
   • HTTP response code 500 (INTERNAL_SERVER_ERROR): any other unexpected failure.
