SpringBatch App Using JDBC for Reading is Failing to Start

I have something very similar to the code below (I had to do some obfiscation). I am getting an Application Failed to Start error. Code not shown are datasource bean and spring boot application class. When I put breakpoints in and all run in debug, all beans appear to be created except the Job and Step bean, which seem to be skipped over entirely. I am not sure how to diagnose further. Seems to be some Spring Magic issues. Any ideas are greatly appreciated.

Here is the exception:

Description:

Parameter 0 of method databaseCursorStep in com.configuration.BatchConfig required a bean of type 'org.springframework.batch.item.ItemReader' that could not be found.

The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Qualifier(value=databaseCursorItemReader)

Action:

Consider defining a bean of type 'org.springframework.batch.item.ItemReader' in your configuration.

Here is the code:

@Configuration
@EnableBatchProcessing
public class BatchConfig {
@Autowired
public JobBuilderFactory jobBuilderFactory;
@Autowired
public StepBuilderFactory stepBuilderFactory;
private static final String GET_DATA =
"SELECT " +
"stuffA, " +
"stuffB, " +
"FROM STUFF_TABLE " +
"ORDER BY stuffA ASC";
@Bean
public ItemReader<StuffDto> itemReader(DataSource dataSource) {
return new JdbcCursorItemReaderBuilder<StuffDto>()
.name("cursorItemReader")
.dataSource(dataSource)
.sql(GET_DATA)
.rowMapper(new BeanPropertyRowMapper<>(StuffDto.class))
.build();
}
@Bean
ItemProcessor<StuffDto, StuffDto> databaseXmlItemProcessor() {

}
@Bean

}
@Bean
public Step databaseCursorStep(@Qualifier("databaseCursorItemReader") ItemReader<StuffDto> reader,
@Qualifier("databaseCursorItemWriter") ItemWriter<StuffDto> writer,

return stepBuilderFactory.get("databaseCursorStep")

.writer(writer)
.build();
}
@Bean

return jobBuilderFactory.get("databaseCursorJob")
.incrementer(new RunIdIncrementer())
.flow(exampleJobStep)
.end()
.build();
}
}

Your Qualifier Bean name is itemReader not databaseCursorItemReader. Either change the method name or change to databaseCursorStep(@Qualifier("itemReader")

@Bean
public Step databaseCursorStep(@Qualifier("itemReader") ItemReader<StuffDto> reader,
@Qualifier("databaseCursorItemWriter") ItemWriter<StuffDto> writer,
StepBuilderFactory stepBuilderFactory) {
return stepBuilderFactory.get("databaseCursorStep")
.<StuffDto, StuffDto>chunk(1)
.reader(reader)
.writer(writer)
.build();
}
@Bean
public ItemReader<StuffDto> itemReader(DataSource dataSource) {
return new JdbcCursorItemReaderBuilder<StuffDto>()
.name("cursorItemReader")
.dataSource(dataSource)
.sql(GET_DATA)
.rowMapper(new BeanPropertyRowMapper<>(StuffDto.class))
.build();
}
