I am using a JPAQueryProvider with JpaPagingItemReader. My Batch configuration looks like this:

    @Bean
        public JpaPagingItemReader<MyEntity> getBatchReader() {
            JpaPagingItemReader<MyEntity> reader = new BatchReader();
    
            reader.setName("getDataFromReader");
            reader.setEntityManagerFactory(entityManager);
            reader.setQueryProvider(queryProvider());
            reader.setPageSize(pageSize);
    
            return reader;
        }

@Bean
    public IodsQueryProvider iodsQueryProvider () {
        return new IodsQueryProvider();
    }

This is my query provider:

    public class QueryProvider implements JpaQueryProvider {
        
        
        @PersistenceContext(unitName = "VIEW-DBUNIT")
        private EntityManager entityManager;
    
        @Override
        public Query createQuery() {
    
            Query query = entityManager.createNativeQuery("query");
            query.setParameter(1,DateTimeUtil.formatTimestamp(last_run_date));  // How to get this last_run_date here?
            return query;
        }
    
        @Override
        public void setEntityManager(EntityManager entityManager) {
            this.entityManager = entityManager;
    
        }

I am unable to get last_run_date inside the query provider. I have last_run_date inside the BatchReader thought but unable to pass it down to the query provider.

Here is my BatchReader:

    public class BatchReader extends JpaPagingItemReader{
    
    
        @BeforeStep
        public void beforeStep(StepExecution stepExecution) {
    
            JobExecution jobExecution = stepExecution.getJobExecution();
    
//Getting last_run_date here but unable to pass it down to the query provider.
            Timestamp last_run_date = (Timestamp) jobExecution.getExecutionContext().get(BatchConstants.LAST_RUN_TIME);
                
            }
        }
    
        
        @Override
        protected void doReadPage() {
            Long startTime = System.currentTimeMillis();
            super.doReadPage();
            Long endTime = System.currentTimeMillis();
            Long timeTaken = endTime - startTime;
            LOGGER.info("Data retrieved: page={}, timeTaken={}ms", getPage(), timeTaken);
        }
    
    }

What am I missing here? Please suggest.
