MongoDB Spring Batch job using Gradle - spring

Question

I want to create an item reader, writer and processor for a Spring batch job using Gradle. I am having trouble with a few things. The delimited() portion is giving me an error. I am trying to read two fields for now: rxFname, rxLname.
Here is my code:
#Configuration
#EnableBatchProcessing
public class PaymentPortalJob {
private static final Logger LOG =
LoggerFactory.getLogger(PaymentPortalJob.class);
#Autowired
public JobBuilderFactory jobBuilderFactory;
#Autowired
public StepBuilderFactory stepBuilderFactory;
#Bean
MongoItemReader <PaymentAudit> fileReader(){
return new MongoItemReaderBuilder <PaymentAudit>()
.name("file-reader")
.targetType(PaymentAudit.class)
.delimited().delimiter(",").names(new String [] {"rxFname" , "rxLname"})
.build();
}
#Bean
public ItemProcessor<PaymentAudit, PaymentAudit> processor() {
return new PaymentAuditItemProcessor();
}
#Bean
public ItemWriter<PaymentAudit> writer() {
return new MongoItemWriterBuilder()<PaymentAudit>();
try {
writer.setTemplate(mongoTemplate());
}catch (Exception e) {
LOG.error(e.toString());
}
writer.setCollection("paymentAudit");
return writer;
}
#Bean
Job job (JobBuilderFactory jbf,
StepBuilderFactory sbf,
ItemReader<? extends PaymentAudit> ir,
ItemWriter<? super PaymentAudit> iw) {
Step s1 = sbf.get("file-db")
.<PaymentAudit, PaymentAudit>chunk(100)
.reader(ir)
.writer(iw)
.build();
return jbf.get("etl")
.incrementer(new RunIdIncrementer())
.start(s1)
.build();
}
#Bean
public MongoDbFactory mongoDbFactory() throws Exception {
return new SimpleMongoDbFactory(new MongoClient(), "db-name");
}
#Bean
public MongoTemplate mongoTemplate() throws Exception {
MongoTemplate mongoTemplate = new MongoTemplate(mongoDbFactory());
return mongoTemplate;
}
}
