[batch] parameter 전달방법

출처 - http://www.mkyong.com/spring-batch/spring-batch-example-mysql-database-to-xml/

 

App.java

JobParameters param = new JobParametersBuilder().addString("age", "20").toJobParameters();

 

참고  1) string일경우 예: addString("SEND_YN","'Y'")    : 따옴표 있어야함

        2) jobParametersBuilder.addLong("timestamp", new Date().getTime()); 이런식으로 안하면

            Cannot start a job instance that already exists 오류가 발생한다  

            ==>> 이유는 설정.xml파일에 org.springframework.batch.core.configuration.support.JobRegistryBeanPostProcessor

org.springframework.batch.core.configuration.support.MapJobRegistry

등록되어 있어서 그렇다고함
