spring-batch

I am trying to use Spring batch and implement an aggregated reader (batch file, where multiple records should be treated as one record while writing). Here is the code snippet for my reader: public class AggregatePeekableReader implements ItemReader<List<T>>, ItemStream { private SingleItemPeekableItemReader<T> reader; private boolean process(T currentRecord , InvoiceLineItemsHolder holder) throws UnexpectedInputException, ParseException, Exception { next = peekNextInvoiceRecord(); // finish processing if we hit the end of file if (currentRecord == null ) { LOG.info("Exhausted ItemReader ( END

Is there anyway to use jberet as standalone module to execute Batch Jobs? All the time getting samples on using along with WildFly. Surprised to see it looks for container to load implementations while trying some samples. Any insights on why/why not would be helpful kaape Here is a tutorial how to use jberet in a standalone application: http://www.mastertheboss.com/batch-api/running-batch-jobs-in-j2se-applications You'll need to include various jboss dependencies for it to work. Furthermore you need to configure jberet with a separate jberet.properties. I've build a (hopefully) minimal

I am developing Spring Batch - MongoDB to XML example. In this example, when I run the main method I see the below error is cominng. Please guide on the below error. I tried to find the solution on the web, but I dont find anything helpful on the web yet. Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'step1': Cannot resolve reference to bean 'mongodbItemReader' while setting bean property 'itemReader'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mongodbItemReader'

I am new to Spring Batch. My requirement is I have a reader which gets the records through a web service call/database call and currently I am writing those records to one table. Now I need same records (records read by reader) needs to be processed and write into another table. The point to note here is the second items those are getting stored in second write are of different type of first write. I need like below 1st Step: - Read items of type A --> Write items of Type A 2nd Step:- Read items of type A --> Process to type B ---> Write 10 items of type B For the same above job I need

Following is what we are trying to achieve. We want a big xml file to be staged in a database parallely in different vms. To achieve this, we are using the scalable spring batch remote partition approach and we are running into some issues. Following is the high level setup master - splits an xml file into multiple partitions ( we currently have a grid size of 3). slave 1 - processing partitions (reads index based partitions and writes to DB) slave 2 - processing partitions We are running it in Linux and with active MQ 5.15.3. With the above setup slave 1 is processing 2 partitions at the same

I have encountered an odd issue with a RepositoryItemWriter, where it does not appear to be persisting entities correctly through my configured Spring Data JPA repository to the data source. Step configuration @Bean public Step orderStep(StepBuilderFactory stepBuilderFactory, ItemReader<OrderEncounter> orderEncounterReader, ItemWriter<List<Order>> orderWriter, ItemProcessor<OrderEncounter, List<Order>> orderProcessor, TaskExecutor taskExecutor) { return stepBuilderFactory.get("orderStep") .<OrderEncounter, List<Order>> chunk(10) .reader(orderEncounterReader) .processor(orderProcessor) .writer

Context We have a batch job that replicates localized country names (i.e. translations of country names to different languages) to our DB from the external one. The idea was to process all localized country names for a single country in 1 chunk (i.e. first chunk - all translations for Andorra, next chunk - all translations for U.A.E., etc.). We use JdbcCursorItemReader for reading external data + some oracle analytic functions to provide total number of translations available for the country: something like select country_code, language_code, localized_name, COUNT(1) OVER(PARTITION BY c_lng
