Spring batch sequence job implementation

Getting Started

Performing sequence of tasks with spring batch. Jobs are rely on loading csv files and can be started by rest endpoint.

Configuring sequence of jobs

TaskletStep step1 =
        stepBuilderFactory.get("ETL-file-read1").<User, User>chunk(100)
                .reader(userItemReader1)
                .processor(userItemProcessor)
                .writer(userItemWriter)
                .listener(decider)
                .build();

TaskletStep step2 =
        stepBuilderFactory.get("ETL-file-read2").<User, User>chunk(100)
                .reader(userItemReader2)
                .processor(userItemProcessor)
                .writer(userItemWriter)
                .listener(decider)
                .build();

return jobBuilderFactory.get("ETL-job").incrementer(new RunIdIncrementer())
        .start(step1)
        .next(decider).on(BatchStatus.FAILED.name()).end()
        .from(decider).on(BatchStatus.COMPLETED.name()).to(step2)
        .end()
        .build();
