spring-batch

I have a problem using Spring Batch 2.1.9: when i use jobExplorer.getJobExecution(jobExecutionId) , i find a problem when DAO has to deserialize a string like: {"map":[{"entry":{"string":"parsedComparingDate","date":"2014-03-08 23:00:00.0 UTC"}}]} from the BATCH_JOB_EXECUTION_CONTEXT table, using method JdbcJobExecutionDao.getJobExecution() . I know that spring batch uses xstream 1.3, but in my Pom, i have: spring-batch 2.1.9 ; xstream 1.4.1 (inherited from smooks); jettison 1.3.3 (inherited from cxf); Also, i read that xstream 1.3 does not work fine with jettison 1.3.3, but using xstream 1.3

I'm developing a Spring-Batch project using Spring-Boot and everything is going along nicely. I've done a few spring-batch examples (including some from spring.io), but I'm not sure what some of the stuff does, and "it just works" doesn't satiate me. My spring boot main class implements CommandLineRunner and for this particular job the initial set up looked like @Bean public Job myJob(JobExecutionListenerSupport listener) { return myJobBuilderFactory.get(JOB) .listener(listener) .start(myStep()) .build(); } Which caused java.lang.IllegalStateException: Failed to execute CommandLineRunner at

For now, I'm using jobParameters to get the filenames for both my FlatFileItemReader and FlatFileItemWriter. It's okay for testing my batch, but my goal is to read a file in some directory (there is only this file in this directory) and the filename might change. The output filename should depend on the input filename. Therefore, I thought about adding a new step to my job, and this step will set both output and input filenames by searching the good directory and looking for the file into it. I read Passing Data to Future Steps from Spring Doc, and this thread from SO, but I can't make it work

If the BATCH_JOB_EXECUTION_CONTEXT was not created all I get is : Caused by: org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [INSERT INTO BATCH_JOB_EXECUTION_CONTEXT (SHORT_CONTEXT, SERIALIZED_CONTEXT, JOB_EXECUTION_ID) VALUES(?, ?, ?)]; nested exception is java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not exist the error above is displayed while inserting into the table, but at the moment of the creation of the table (done automatically by spring batch )no error was displayed. I would like to know the reason way the table was not

I'm trying to build a Spring/Spring Boot- RESTful web service, Which accepts a CSV file with 1 million rows/40 columns in each row as input (From a Angular based front end) and will be a synchronous call. User have to be notified on the upload status before proceeding to other screens. So, wait time can't be more than few mins(say 5 mins). Each of these rows has to be validated against what is in DB and if found to be valid, same will be inserted into DB. In short, each row can be a separate independent transaction. Can you please suggest what would be the best approach to implement this?
