Spring Data JPA ManyToOne query null - spring

Question

I've started to learn Spring Boot, I've created two entities Invoice and YearDate
When I try to search by year(id), in my log query I got null (see this part of log query)
http://localhost:8080/appapi/invoices/search/findByYearId?year=1
from invoice invoice0_ left outer join year_date yeardate1_ on invoice0_.year_id=yeardate1_.id where yeardate1_.id is null limit?
I'm using Lombok also for getters and setters
Here are all my class entities, SQL tables, and JpaRepository interface :
SQL foreign key :
KEY `fk_year` (`year_id`),
CONSTRAINT `fk_year` FOREIGN KEY (`year_id`) REFERENCES `YearDate` (`id`)
YearDate class :
#Entity
#Table(name="YearDate")
#Data
public class YearDate {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id")
private Long id;
#Column(name = "year_value")
private String yearValue;
#OneToMany(cascade = CascadeType.ALL, mappedBy = "year")
private Set<Invoice> invoices;
}
Invoice class:
#Entity
#Table(name="invoice")
#Data
public class Invoice {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id")
private Long id;
#Column(name = "name")
private String name;
#ManyToOne
#JoinColumn(name = "year_id", nullable = false)
private YearDate year;
#Column(name = "description")
private String description;
}
**And The Invoice Interface:**
#CrossOrigin("http://localhost:4200")
public interface InvoiceRepository extends JpaRepository<Invoice, Long> {
Page<Invoice> findByYearId(#RequestParam("year") Long id, Pageable page);
}

Answer 1

Work for me.
try to extract call in rest controller and log params
#GetMapping(value = "/invoices")
public Page<Invoice> getInvoices(#RequestParam("yearId") Long yearId) {
Page<Invoice> byYearId = invoiceRepository.findByYearId(yearId, PageRequest.of(0, 10));
return byYearId;
}
public interface InvoiceRepository extends JpaRepository<Invoice, Long> {
Page<Invoice> findByYearId(Long id, Pageable page);
}
#ManyToOne
#JoinColumn(name = "year_id", nullable = false)
#JsonIgnoreProperties("invoices")
private YearDate year;
#OneToMany(mappedBy = "year")
#JsonIgnoreProperties("year")
private Set<Invoice> invoices;
Generated SQL :
Hibernate:
select
invoice0_.id as id1_0_,
invoice0_.description as descript2_0_,
invoice0_.name as name3_0_,
invoice0_.year_id as year_id4_0_
from
invoice invoice0_
left outer join
year_date yeardate1_
on invoice0_.year_id=yeardate1_.id
where
yeardate1_.id=? limit ?
Hibernate:
select
yeardate0_.id as id1_5_0_,
yeardate0_.year_value as year_val2_5_0_
from
year_date yeardate0_
where
yeardate0_.id=?
-> ADD #JsonIgnoreProperties("invoices") and #JsonIgnoreProperties("year") to entities to avoid infinite json recusrsion.

Answer 2

I've disabled Lombok and it works

Answer 3

try pass him a Year object not id is better
#CrossOrigin("http://localhost:4200")
public interface InvoiceRepository extends JpaRepository<Invoice, Long> {
Page<Invoice> findByYear(YearDate year, Pageable page);
}
and in your service get this year
for exemple I create a getYears method in service:
#Service
public class YearService{
#Autowired
private YearRepository yearRepository;
#Autowired
private InvoiceRepository invoiceRepository;
getYears(idYear:Long){
YearDate yearParam=yearRepository.findById(id).get();
Page<Invoice> invoices=invoiceRepository.findByYear(yearParam,YourPagination)
}
}
