Я пытаюсь получить аннотации параметров работы в элементе процессора с помощью Spring-Batch-Annotation.
Я реализовал это, перейдя по ссылке ниже; но для меня переменная (batchRunName) становится нулевой, когда я пытаюсь получить к ней доступ в своем классе Processor.
Может кто-нибудь, пожалуйста, посмотрите на это. Я уверен; Мне не хватает какой-то мелочи.
Как передать параметры задания в обработчик элементов, используя аннотацию Spring Batch
public static void main(String[] args) {
contextObj = new ClassPathXmlApplicationContext(springConfig);
jobObj = (Job) contextObj.getBean("XYZ-1001-DD-01");
JobParametersBuilder jobBuilder = new JobParametersBuilder();
System.out.println("args[0] is " + args[0] );
jobBuilder.addString("batchRunName", args[0]);
public class TimeProcessor implements ItemProcessor<Time, TimeMetric> {
private DataSource dataSource;
@Value("#{jobParameters['batchRunNumber']}")
private String batchRunNumber;
public void setBatchRunNumber(String batchRunNumber) {
this.batchRunNumber = batchRunNumber;
}
