How to use HibernateCursorItemReader in spring batch

In a spring batch job, I have a step in which I want to read data by chunk from the database using Hibernate, process it and write it back to the database. Right now I'm having some trouble setting up the reader :
#EnableBatchProcessing
#Configuration
#ComponentScan(basePackages = {"com.x.y.z.database", "com.x.y.p.database"}, excludeFilters={
#ComponentScan.Filter(type= FilterType.ASSIGNABLE_TYPE, value=ConfigHelperMail.class)})
#EntityScan(basePackages = {"com.x.y.z.database", "com.x.y.p.database"})
#EnableJpaRepositories({"com.x.y.z.database", "com.x.y.p.database"})
public class BatchConfiguration {
#Autowired
public JobBuilderFactory jobs;
#Bean
public Job job(CustomJobListener listener,
#Qualifier("step1") Step step1,
#Qualifier("step2") Step step2,
#Qualifier("step3") Step step3) {
return jobs.get("SimpleJobName")
.incrementer(new RunIdIncrementer())
.preventRestart()
.listener(listener)
.start(step1)
.next(step2)
.next(step3)
.build();
}
}
In step1 writer I save the data to the database using Hibernate :
#Entity
#Table(name = "tmp_z_stepone")
public class StepOneEntity {
#Id
#Column(name = "reference")
private String reference;
/** Other properties and getters and setters **/
}
#Component
public class StepOneWriter implements ItemWriter<StepOneEntity> {
#Autowired
private StepOneService stepOneService;
#Override
public void write (List<? extends StepOneEntity> items) throws WriterException {
stepOneService.saveMany(items);
}
}
StepOneService is annotated with #Service and it uses a DAO interface that extends CrudRepository<StepOneEntity, String> and its saveMany method just uses the save method from CrudRepository<StepOneEntity, String>.
Step 2
#Component
public class StepOne {
#Autowired
private StepTwoReader reader;
#Autowired
private StepTwoProcessor processor;
#Autowired
private StepTwoWriter writer;
#Bean
#JobScope
#Qualifier("step2")
public Step step2() throws ReaderException {
return stepBuilderFactory.get("step2")
.<StepOneEntity, StepTwoEntity>chunk(10)
.reader(reader.read())
.processor(processor)
.writer(writer)
.build();
}
}
#Component
public class StepTwoReader {
public ItemReader<OutputControleFormat> read () throws ReaderException {
HibernateCursorItemReader itemReader = new HibernateCursorItemReader();
itemReader.setQueryString("from tmp_z_stepone");
itemReader.setUseStatelessSession(true);
return itemReader;
}
}
I think I'm missionf some session/ORM configuration but I don't know where, the error is below :

HibernateCursorItemReader implements the InitializingBean interface, which means that Spring will call its afterPropertiesSet on container initialization if it is declared as a bean. However, in your case, the HibernateCursorItemReader is not declared as a bean in the application context, it is wrapped in a class (StepTwoReader) then created with reader.read().
If you declare the HibernateCursorItemReader as a bean with your current code in your read method, you should get an IllegalStateException with message: "A SessionFactory must be provided". You actually need to configure a SessionFactory for your Hibernate reader.
Another option is to use the HibernateCursorItemReaderBuilder which will ensure the reader is correctly configured.

#StepScope
#Slf4j
#Component
public class CursorItemReader extends HibernateCursorItemReader<ItemEntity> {
public CursorItemReader(EntityManagerFactory entityManagerFactory,
#Value("#{stepExecution}")StepExecution stepExecution) {
this.setName("CursorItemReader");
this.setSessionFactory(entityManagerFactory.createEntityManager().unwrap(org.hibernate.Session.class).getSessionFactory());
this.setQueryString("from ItemEntity");
this.setUseStatelessSession(true);
this.setFetchSize(5);
}
#Override
public ItemEntity read() throws Exception {
ItemEntity item = this.doRead();
return item;
}
}

spring batch Classifier: Writer must be open before it can be written to

I'm new to spring and which to split database to 3 csv files.
My actual code: (I'm not using xml and don't want to)
I've tried many solutions but nothing work.
class MyClassifier {
#Classifier
public String classify(Pojo Pojo) {
return String.valueOf(Pojo.getYear());
}
}
#Bean(name = "PojoWriter")
#StepScope
public ItemWriter<Pojo> itemWriter() throws Exception {

classifier.setRouterDelegate(new MyClassifier());
classifier.setMatcherMap(new HashMap<String, FlatFileItemWriter<? super Pojo>>() {
FlatFileItemWriter<Pojo> writerH;
{
writerH = writer("2017",null,null); put("2017", writerH); writerH.close();
writerH = writer("2018",null,null); put("2018", writerH); writerH.close();
writerH = writer("2019",null,null); put("2019", writerH); writerH.close();
}
});
ClassifierCompositeItemWriter<Pojo> writer = new ClassifierCompositeItemWriter<Pojo>();
writer.setClassifier(classifier);
return writer;
}
I classify with year, and 3 files are created

Spring data JPA findFirst with where clause (filtering) and order by, internal exception thrown

I created the following repository
public interface DemoRepository extends CrudRepository<DemoEntity, DemoId> {
Optional<DemoEntity> findFirstByPositionIsNotNullOrderByIdCompositeFieldIdDesc(Long compositeFieldId);
}
And the entity class:
#Entity
#Table(name = "demo")
public class DemoEntity {
#EmbeddedId
private DemoId id;
#Column(name = "result_position")
private Integer position;
public DemoEntity() {
}
public DemoEntity(DemoId id) {
this.id = id;
}
public DemoId getId() {
return id;
}
public void setId(final DemoId id) {
this.id = id;
}
public Integer getPosition() {
return position;
}
public void setPosition(final Integer position) {
this.position = position;
}
}
And the composite id of the entity class:
#Embeddable
public class DemoId implements Serializable {
private static final long serialVersionUID = 4782012819350949578L;
#Column
private Long compositeFieldId;
#Column
private Long compositeFieldIdSecond;
public DemoId() {}
public DemoId(final Long compositeFieldId, final Long compositeFieldIdSecond) {
this.compositeFieldId = compositeFieldId;
this.compositeFieldIdSecond = compositeFieldIdSecond;
}
public Long getCompositeFieldId() {
return compositeFieldId;
}

this.compositeFieldId = compositeFieldId;
}
public Long getCompositeFieldIdSecond() {

}
public void setCompositeFieldIdSecond(final Long compositeFieldIdSecond) {
this.compositeFieldIdSecond = compositeFieldIdSecond;
}
}

The exception kinda makes sense as the query should return no result in my test, but I would expect to get an empty optional instead of an exception.
Is this a bug or I am mis-using Spring Data? The db is mysql 5.7.
I then tried to upgrade to Spring Boot 2.0 which includes Spring Data Jpa 2.0.5, now the app fails to create the repository during start up:

Still don't get why as the exception is not descriptive.
Thank you.

Found the issue, my repository method expects a parameter which is not needed by the query itself. Anyway the exception reported by Spring Data is a bit confusing, I've logged a bug in their bugtracker and they are looking at it: https://jira.spring.io/browse/DATAJPA-1281

RepositoryItemReader: java.util.ArrayList cannot be cast to org.springframework.data.domain.Page

I'm setting up an ItemRepositoryReader for the reader in a spring batch step. I wanna use findByScenarioBetween method which takes two parameters, min, and max.
My repo
public interface FuneralPricingRepository extends JpaRepository<FuneralPricing, Long> {
#Query("select p from FuneralPricing p where p.scenario between ?1 and ?2")
List<FuneralPricing> findByScenarioBetween(Long min, Long max, Pageable pageable);
}
My Reader
#Bean
#StepScope
public ItemReader<FuneralPricing> funeralPricingRepositoryReader(
#Value("#{jobParameters[start]}") Long start,
#Value("#{jobParameters[end]}") Long end) {
RepositoryItemReader<FuneralPricing> repositoryItemReader = new RepositoryItemReader<>();
repositoryItemReader.setPageSize(10);
repositoryItemReader.setSort(funeralPricingSort());
repositoryItemReader.setRepository(funeralPricingRepository);
repositoryItemReader.setMaxItemCount(100);
repositoryItemReader.setMethodName("findByScenarioBetween");
List parameters = new ArrayList();
parameters.add(start);
parameters.add(end);
repositoryItemReader.setArguments(parameters);
return repositoryItemReader;
}
When I use findAll it's working fine. But then I don't wanna read all row every time. I don't know if I am missing something in my reader!, Thanks.
