Class SpringBootBatchCommandLine

java.lang.Object

com.devonfw.module.batch.common.base.SpringBootBatchCommandLine

public class SpringBootBatchCommandLine
extends Object

Launcher for launching batch jobs from the command line when Spring Boot is used. Similar to the CommandLineJobRunner, which does not work very well with Spring Boot.

Do not use this class if Spring Boot is not used!

It expects the full class name of the Spring Boot configuration class to be used as first argument, the class/XML file for configuring the job as second argument and the job name as third.
Moreover parameters can be specified as further arguments (convention: key1=value1 key2=value2 ...).

Example:
java com.devonfw.module.batch.common.base.SpringBootBatchCommandLine com.devonfw.gastronomy.restaurant.SpringBootBatchApp classpath:config/app/batch/beans-productimport.xml productImportJob drinks.file=file:import/drinks.csv date(date)=2015/12/20

For stopping all running executions of a job, use the -stop option.

Example:
java com.devonfw.module.batch.common.base.SpringBootBatchCommandLine com.devonfw.gastronomy.restaurant.SpringBootBatchApp classpath:config/app/batch/beans-productimport.xml productImportJob -stop
