I'm using the following factories to set up my Spring Batch application:
private JobBuilderFactory jobBuilderFactory; private StepBuilderFactory stepBuilderFactory; However, I'm getting the following deprecation warning:
The type JobBuilderFactory has been deprecated since version 5.0.0 and marked for removal These are the bean declarations I'm using:
@Bean public Step step1() { return stepBuilderFactory .get("csv-step") .<MSTabcNEUser, MSTabcNEUser>chunk(10) .reader(reader()) .processor(processor()) .writer(writer()) .taskExecutor(taskExecutor()) .build(); } @Bean public Job runJob() { return jobBuilderFactory .get("MSTabcNEUser") .flow(step1()) .end() .build(); } I'm also getting the following error:

In stead of using JobBuilderFactory and StepBuilderFactory, you can use the JobBuilder and StepBuilder class:
@Bean public Step step1() { return new StepBuilder("csv-step", jobRepository) .<MSTabcNEUser, MSTabcNEUser>chunk(10, transactionManager) .reader(reader()) .processor(processor()) .writer(writer()) .taskExecutor(taskExecutor()) .build(); } @Bean public Job runJob() { return new JobBuilder("MSTabcNEUser", jobRepository) .start(step1()) .build(); } The big difference is that you need to pass a JobRepository to these builders and a PlatformTransactionManager to the chunk() method. You can add these as fields to your configuration class. For example:
private JobRepository jobRepository; private PlatformTransactionManager transactionManager; Also be aware that the ItemWriter interface has changed from supporting a collection of items to Chunk<? extends T>. You may have to refactor some of your writers. Check also the Spring Batch 5.0 migration guide.
