spring-batch

I want to use Spring Batch and Spring Integration to import data from database and write them into a file and ftp them to a remote server. But I guess my problem is I don't want to create Domain Object for my table. My queries are random and I want something that just reads the data and writes it to files and transfer. Can I use Spring Batch and Integration without creating respective domain objects? Absolutely. You can use either of the JDBC ItemReader s or the JPA ItemReader with a ColumnMapRowMapper to retrieve a Map of the result set. You can use the FlatFileItemWriter pretty simply to

I wrote a spring batch job that processes List of Lists. Reader returns List of List. Processor works on each ListItem and returns processed List. Writer writes stuff to DB and sftp from List of List. I have a use case where I call Async REST api from spring batch processor. On ListenableFuture response I implemented LitenableFutureCallback to handle success and failure, which works as expected, but before the async call returns something, ItemProcessor dosen't wait for call backs from async api and returns object(List) to writer. I am not sure how to implement and handle async calls from

I know right now there is no such thing as inter-step transactionality in Spring-Batch. I'm developing a complex batch job, with many steps performing several actions in database, and each one is related with the others, in such way that each one of them belongs to the same transaction. The way I understand the Spring-Batch paradigm I'm bound to use one-step job in order to have transactionality. Is there any thought (or any other way) to have some kind of job-level transactionality in lately or future versions? Edit1: I have found in this link , point 6.3.1, a way to concatenate several

I tried spring.batch.job.enabled=false in application.properties and -Dspring.batch.job.enabled=false when running the jar file. However @EnableBatchProcessing automatically start running the batch jobs on application start. How i can debug such scenario? TestConfiguration.class @Configuration @EnableBatchProcessing public class TestConfiguration {...} MainApplication @ComponentScan("com.demo") @EnableAutoConfiguration public class MainApplication { public static void main(String[] args) throws BeansException, JobExecutionAlreadyRunningException, JobInstanceAlreadyCompleteException,

I am having the Web-service method to start spring batch job.If any exception occurred in spring batch processing control is coming back till processor process method. But i need the controller to came back to web-service method there i have to catch and code to email that exception. Web-service method: public void processInputFiles() throws ServiceFault { String[] springConfig = { CONTEXT_FILE_NAME }; ApplicationContext context = new ClassPathXmlApplicationContext(springConfig); try { setClientInfo(); JobLauncher jobLauncher = (JobLauncher) context.getBean(JOB_LAUNCHER); Job job = (Job)
