I am working in spring boot project. In my JPA repository, I am using sql native query with pagination enabled. However on service layer I am getting ConvertorNotFoundException.. tried many times with different data types..but all in vain. Below are my code classes:
Repository interface
public interface ContentSongsRepository extends JpaRepository<ContentSongs,Long>{
#Query(value= "SELECT date(start_date) as DATEE, sum(case when subscription_from in ('IVR','SMS') and remarks like '%Change Song%' then 1 else 0 end) as 'song_change' from subscription group by date(start_date) \n#pageable\n",nativeQuery=true)
Page<SongChangeCount> getSongChangeCount2(Pageable page);
}
Sql query is running fine.. below is image.
Service layer method calling repository
#Override
public SongChangeCountView getSongChangeCount(Pageable page) {
// TODO Auto-generated method stub
Page<SongChangeCount> songChangePageList = contantSongRepository.getSongChangeCount2(page);
List<SongChangeCount> list = songChangePageList.getContent();
Integer pageCount = songChangePageList.getTotalPages();
Long totalElement = songChangePageList.getTotalElements();
SongChangeCountView sccv = new SongChangeCountView();
sccv.setLsSongChangeCountView(list);
sccv.setPageCount(pageCount);
sccv.setTotalElement(totalElement);
return sccv;
}
SongChangeCount class
import java.io.Serializable;
import java.util.Date;
import javax.persistence.Entity;
public class SongChangeCount implements Serializable{
private static final long serialVersionUID = -5410845856201124932L;
private Date DATEE;
private String song_change;
public SongChangeCount(Date dATEE, String song_change) {
DATEE = dATEE;
this.song_change = song_change;
}
public Date getDATEE() {
return DATEE;
}
public void setDATEE(Date dATEE) {
DATEE = dATEE;
}
public String getSong_change() {
return song_change;
}
public void setSong_change(String song_change) {
this.song_change = song_change;
}
}
Every time when I run the code below exception comes:

Can anyone tell me whats going wrong here..I tried changing the Date data type to java date but still it didn't solve my issue.
Your ContentSongsRepository must extends JpaRepository<SongChangeCount, Date>

Any idea why could I be getting below error with following code?

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;
}
public void setCompositeFieldId(final Long compositeFieldId) {
this.compositeFieldId = compositeFieldId;
}
public Long getCompositeFieldIdSecond() {
return compositeFieldIdSecond;
}
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
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.

I have two classes. One is Question, one is TempQuestion:
#Entity
#Table(name="tbQuestion")
#DiscriminatorColumn(
name="discriminator",
discriminatorType=DiscriminatorType.STRING)
#Inheritance(strategy=InheritanceType.JOINED)
public abstract class Question {
private Integer qstId;
private String qstNum;
private Integer versionNum;
private String qstTitle;
private String qstInstruction;
private InterviewQstType qstType;
private boolean isChildQuestion;
private AnswerDataType answerDataType;
private String chartNodeLocation;
private Question parentQst;
private Set<Question> childQsts;
private Set<QstOption> options;
private Set<Answer> answers;
private List<QstOption> jumpTrgs;
.....
}
#Entity
#Table(name="tb_temp_question")
#DiscriminatorValue("temporary")
#PrimaryKeyJoinColumn(name="qstId")
#OnDelete(action = OnDeleteAction.CASCADE)
public class TempQuestion extends Question{
}
There is no any field only in TempQuestion (Just for testing purpose).
When I insert several records of data into these two tables, it works fine.
But When I try to delete all of them with the coding below, it gives me an error.
#Autowired
private SessionFactory sessionFactory;
public void deleteAll{
Session session = sessionFactory.openSession();
String stringQuery = "DELETE FROM TempQuestion";
Query query = session.createQuery(stringQuery);
query.executeUpdate();
}

I have searched for a long time, but I cannot find a correct answer for this. It seems not many people had this problem. Please help. Thanks.
I have a spring-batch #Job defined. But when running it (inside tomcat), I'm getting a ClassCastException due to com.sun.proxy.$Proxy.
Why could this be the case? What might be wrong in the following excerpt?
#Service
public class JobService {
#Autowired
private JobLauncher launcher;
public void run() {
Job job = jobRegistry.getJob("jobname");
launcher.run(job, params); //line 59
}
}
#Configuration
#EnableBatchProcessing(modular = true)
public class JobConfig {
#Bean
#JobScope
public MultiResourceItemReader<T> reader(#Value("#{jobParameters['filename']}") Resource csv) throws Exception {
MultiResourceItemReader<T> itemReader = new MultiResourceItemReader<>();
//...
return itemReader;
}
#Bean
public JobScope jobScope() {
return new JobScope();
}
}
Result:
java.lang.ClassCastException: com.sun.proxy.$Proxy135 cannot be cast to org.springframework.batch.item.file.MultiResourceItemReader
