I have created a multi-step Spring Batch application. I have defined a separate utility to return a JdbcItemReader instance for each step. Is there any way to make this a generic function? I have tried making it a generic function and putting @StepScope on it, but I am getting an error as provided below.

Implementation of generic utility that returns instance of JDBCItemWriter
@Configuration
public class WriterConfiguration
{
@Autowired
private DataSource datasource;
@StepScope
@Bean
public <T> JdbcBatchItemWriter<T> createJdbcBatchItemWriter(Class<T> entityClass) {
return new JdbcItemWriter<>(datasource, entityClass);
}
Implementation of batch steps where I am using the utility
@Configuration
public class StepsConfiguration
{
@Autowired
ReaderConfiguration readerConfiguration;
@Autowired
WriterConfiguration writerConfiguration;
@Autowired
private StepBuilderFactory stepBuilderFactory;
@Bean
public Step processNvBooking()
{
return stepBuilderFactory.get(LCCBatchProcessingConstants.STEPS.PROCESS_NV_BOOKING.getValue()).<NvBooking, NvBooking> chunk(5).reader(readerConfiguration.nvBookingReader(null)).writer(writerConfiguration.createJdbcBatchItemWriter(NvBooking.class))
.build();
}
@Bean
public Step processNvAccount()
{
return stepBuilderFactory.get("processNvAccount").<NvAccount, NvAccount> chunk(5).reader(readerConfiguration.nvAccountReader(null)).writer(writerConfiguration.createJdbcBatchItemWriter(NvAccount.class)).build();
}
The error is due to the
createJdbcBatchItemWritermethod: this method defines a bean namedcreateJdbcBatchItemWriterwhich has a dependency of typeClass, expressed through the parameter of the method. Since (i guess) there is no bean of typeClassin the application context, that error happens.Try to remove the
@Beanand@StepScopeand call that method where needed with the target type. You will end up with a new instance of the writer every time.
