I have UserRepository:
public interface UserRepository extends JpaRepository<User, String> {}
The entity:
#Entity
#Table(schema="test", name = "TBL_USERS")
#Builder
#AllArgsConstructor
public class User implements Persistable<String> {
#Id
#Column(name = "ID", columnDefinition = "char")
private String id;
#NotNull
#Column(name = "NAME", columnDefinition = "char", nullable = false)
private String name;
...
}
And in my test I want to count records with certain name like the query:
select count(*) from TBL_USERS where name='John';
#Test
public void testCountSimilarNames() {
...
userRepository.count() ... ?
}
I use latest spring-boot.
You need something like :
public interface UserRepository extends CrudRepository<User , String >{
Integer countByName(String name);
}

I'm working on an exercise where i have to create CRUD operations.
I have a User table, a Role table and a UserRole table where i have the primary keys of those two entities.
I also have a RoleEnum with roles that have to be assigned to the User.
The problem that i'm gettin is that every time I insert a new user is a 200ok response but the role returns null and so it doesn't add it to the UserRole table as well.
I need help in solving the problem.
User Entity

public class Utente implements Serializable {

return ruoli;
}
}
return null;
}
}
I also have all DTO's and the UserDTO has the RoleEnum instead of the List of class UserRole.
UserService
#Service
public class UtenteService {
#Autowired
private UtenteRepository utenteRepository;
#Autowired
private UtenteMap utenteMap;
public UtenteDto addUtente(UtenteDto utente) {
Utente u = utenteMap.fromDtoToModel(utente);
if(u != null) {
return utenteMap.fromModelToDto(utenteRepository.save(u));
}
return null;
}
UserController
#RestController
#RequestMapping("utente")
public class UtenteController {
#Autowired
private UtenteService utenteService;
#PostMapping("/addUtente")
public ResponseEntity addUtente(#Nullable #RequestBody UtenteDto utente) {
if(utente != null) {
return ResponseEntity.ok(utenteService.addUtente(utente));
} else {
return ResponseEntity.badRequest().body("utente non inserito correttamente");
}
}
this is a postman insert example:
{
"matricola" : 11,
"nome" : "aaa",
"cognome" : "bb",
"email" : "eee#mail.com",
"ruolo" : "APPROVATORE"
}
and this is the postman response with 200ok status:
{
"matricola": 11,
"nome": "aaa",
"cognome": "bb",
"email": "eee#mail.com",
"ruolo": null
}
the code doesn't tell me about any kind of error and i need to keep the UserRole table because it's required for this kind of exercise.
I tried everything I could but since I never worked like this with enums and this kind of table relations I don't know what's missing to complete it.
I'm trying to make a existsBy query using a property that comes from an embedded class, but I'm receiving "No property 'cpf' found for type 'Patient'".
The class Patient uses the Person class as embedded.
Person.java
#Embeddable
#Data
public class Person {
#Column(nullable = false, length = 11)
private String cpf;
#Column(name = "full_name", nullable = false, length = 60)
private String fullName;
#Column(nullable = false)
private String birthdate;
#Column(name = "email", nullable = true, length = 30)
private String emailAddress;
#Column(name = "cellphone_number", nullable = true, length = 11)
private String cellphoneNumber;
}
Patient.java
#Data
#Entity
#Table(name = "tb_patient")
public class Patient implements Serializable {
#Serial
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "patient_id")
private UUID id;
#Column
private LocalDateTime registrationDate;
#Embedded
private Person Person;
}
PatientController.java (part of)
#PostMapping
public ResponseEntity<Object> savePatient(#RequestBody Person person) {
if(patientService.existsByCpf(person.getCpf())) {
return ResponseEntity.status(HttpStatus.CONFLICT).body("CONFLICT: CPF number is already in use!");
}
var patientModel = new Patient();
BeanUtils.copyProperties(person, patientModel);
patientModel.setRegistrationDate(LocalDateTime.now(ZoneId.of("UTC")));
return ResponseEntity.status(HttpStatus.CREATED).body(patientService.save(patientModel));
}
PatientService.java (part of)
#Service
public class PatientService {
final PatientRepository patientRepository;
public PatientService(PatientRepository patientRepository) {
this.patientRepository = patientRepository;
}
public boolean existsByCpf(String cpf) {
return patientRepository.existsByCpf((cpf));
}
PatientRepository.java
#Repository
public interface PatientRepository extends JpaRepository<Patient, UUID> {
boolean existsByCpf(String cpf);
}
How can I pass the #Embedded properties to the #Repository?
You can try separate by _ embedded filed name and it's filed.
#Repository
public interface PatientRepository extends JpaRepository<Patient, UUID> {
boolean existsByPerson_Cpf(String cpf);
}
I'm trying to get a list of transactions from database and this is the error I'm facing.
"trace": "org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.Object[]] to type [com.wallet.sendmoney.entities.TransactionEntity] for value '{1, 1, null, null, KES, null, 123456, LQALVZCFJMU6, null, 2547XXXXXX3, 61234, Load wallet, null, null, null, null, null, WS322, null}'; nested exception is org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.math.BigInteger] to type [com.wallet.sendmoney.entities.TransactionEntity]

public interface TransactionsRepository extends JpaRepository<LoadWalletEntity, Long> {
#Query(value = "SELECT * FROM transactions_attempts WHERE mobile_number= :mobile_number", nativeQuery = true)

}
What could I be missing or doing wrong here.
Thanks in advance
you are trying to query a list of TransactionEntity
but your Repository is extends with
extends JpaRepository<LoadWalletEntity, Long> {
what's this LoadWalletEntity????
it should be
extends JpaRepository<TransactionEntity, Long> {
Try this solution please:
#Entity
#Table(name = "transactions_attempts")
instead of
#Entity(name = "transactions_attempts")
#Table
I have used the #CreatedBy, #CreatedDate, #LastModifiedBy, and #LastModifiedDate annotation on their respective fields. By using #MappedSuperclass,#EntityListeners i able to persist above columns.
But this is not working for the below case:
#MappedSuperclass
#EntityListeners(AuditingEntityListener.class)
public abstract class Auditable<U> {
#CreatedBy
protected U createdBy;
#CreatedDate
#Temporal(TIMESTAMP)
protected Date creationDate;
#LastModifiedBy
protected U lastModifiedBy;
#LastModifiedDate
#Temporal(TIMESTAMP)
protected Date lastModifiedDate;
}
#Entity
#Table(name = "tabel1")
#PrimaryKeyJoinColumn(name = "ID")
class A extends B {
#Column(name = "NAME1", nullable = false)
private String name1;
#Column(name = "CONTENT1", nullable = false)
private String content1;
}
#Entity
#Table(name = "tabel2")
public abstract class B extends Auditable{
#Id
#GeneratedValue
#Column(name = "ID", nullable = false)
private int id;
#Column(name = "NAME", nullable = false)
private String name;
#Column(name = "CONTENT", nullable = false)
private String content;
}
AuditorAwareImpl.java
public class AuditorAwareImpl implements AuditorAware<String>
{
#Override
public Optional<String> getCurrentAuditor()
{
return Optional.ofNullable("Saravanan");
}
}
JpaAuditConfiguration.java
#Configuration
#EnableJpaAuditing(auditorAwareRef = "auditorProvider")
public class JpaAuditConfiguration
{
#Bean
public AuditorAware<String> auditorProvider()
{
return new AuditorAwareImpl();
}
}
In the case, Entity B is populated with audit columns. But Entity A is not. Is there a way to populate Entity A or did i missed anything here..??
I added #Entity annotation to your classes:
#Entity
public class A extends B {
#Id
#GeneratedValue
private Integer id;
private String name;
private String content;
}
#Entity
public class B extends Auditable<String> {
#Id
#GeneratedValue
private Integer id;
private String name;
private String content;
}
Persistence config class (for Spring Boot):
#Configuration
#EnableJpaAuditing
public class PersistenceConfig {
}
Everything works perfectly!
I have some tables and I want to get result using queryDSL join, but haven't found any examples on multiple joins using queryDSL.
I have these tables:
Account table: accountId (PK) | email | password
account_profile table: accountId (PK)(fk to account) | nickname
Community table: articleId (PK) | accountId (fk to account) | title | content
Now I want below JPQL to be queryDSL code
select r from community r join r.account.profile a where a.nickname = :nickname
I have entity metamodels - QAccount, QAccountProfile, QCommunity
Additionally, I have to get the result with pagination, so the query should be called with pageable object.
Here is my work that doesn't work yet.
JPAQuery</*What generic type expected?*/> query = new JPAQuery</*???*/>(entityManager);
Predicate predicate = query.from(QCommunity.community).join(/*join directly accountProfile? or account? is it QEntity or real entity?*/);
// where should I place nickname matching condition ?
...
list = (repository.findAll(predicate, pageable)).getContent();
Where should I place the nickname matching condition?
EDIT: Appended entity information

private Set<CommunityReply> replies;
}
EDIT: PROBLEM SOLVED
To help others who is facing the problem like me, I am gonna post my working code. the code is searching any community articles with matching specific nickname.
#PersistenceContext
private EntityManager entityManager;
private List<Community> getList(int pageNo, String keyword, int rowsOnPage){
int offset = (pageNo -1) * rowsOnPage;
int limit = rowsOnPage;
JPAQuery<Community> query = new JPAQuery<Community>(entityManager);
QCommunity qCommunity = QCommunity.community;
QAccount qAccount = QAccount.account;
QAccountProfile qAccountProfile = QAccountProfile.accountProfile;
return query
.from(qCommunity)
.innerJoin(qCommunity.account ,qAccount)
.innerJoin(qAccount.profile, qAccountProfile)
.where(qAccountProfile.nickname.like("%"+keyword+"%"))
.orderBy(qCommunity.articleId.desc())
.offset(offset)
.limit(limit)
.fetch();
}
First of all, declare a custom extended base repository class for QueryDSL queries.
First the interface:
#NoRepositoryBean
public interface ExtendedQueryDslJpaRepository<T, ID extends Serializable>
extends JpaRepository<T, ID>, QueryDslPredicateExecutor<T> {
<T1> Page<T1> findAll(JPQLQuery jpqlQuery, Pageable pageable);
}
And then the implementation:
public class ExtendedQueryDslJpaRepositoryImpl<T, ID extends Serializable>
extends QueryDslJpaRepository<T, ID> implements ExtendedQueryDslJpaRepository<T, ID> {
private static final EntityPathResolver DEFAULT_ENTITY_PATH_RESOLVER = SimpleEntityPathResolver.INSTANCE;
private final EntityPath<T> path;
private final PathBuilder<T> builder;
private final Querydsl querydsl;
private EntityManager entityManager;
public ExtendedQueryDslJpaRepositoryImpl(JpaEntityInformation<T, ID> entityInformation, EntityManager entityManager) {
this(entityInformation, entityManager, DEFAULT_ENTITY_PATH_RESOLVER);
}
public ExtendedQueryDslJpaRepositoryImpl(JpaEntityInformation<T, ID> entityInformation,
EntityManager entityManager, EntityPathResolver resolver) {
super(entityInformation, entityManager);
this.path = resolver.createPath(entityInformation.getJavaType());
this.builder = new PathBuilder(this.path.getType(), this.path.getMetadata());
this.querydsl = new Querydsl(entityManager, this.builder);
this.entityManager = entityManager;
}
#Override
public <T1> Page<T1> findAll(JPQLQuery jpqlQuery, Pageable pageable) {
// Count query
final JPQLQuery<?> countQuery = jpqlQuery;
// Apply pagination
JPQLQuery<T1> query = querydsl.applyPagination(pageable, jpqlQuery);
// Run query
return PageableExecutionUtils.getPage(query.fetch(), pageable, countQuery::fetchCount);
}
}
Define the new class as base for base and repositories in a #Configuration class.
#Configuration
#EnableJpaRepositories(basePackageClasses = ..., repositoryBaseClass = ExtendedQueryDslJpaRepositoryImpl.class)
Your repositories then should extend from the new interface (which of course extends JpaRepository):
#Repository
public interface CommunityRepository extends ExtendedQueryDslJpaRepository<Community, Long> {
}
Then, you can try the following code:
String nickname = "nick";
QAccount account = QAccount.account;
QAccountProfile accountProfile = QAccountProfile.accountProfile;
QCommunity community = QCommunity.community;
JPQLQuery query = new JPAQuery(entityManager);
BooleanBuilder predicate = new BooleanBuilder();
predicate.and(accountProfile.nickname.eq(nickname));
// select r from community r join r.account.profile a where a.nickname = :nickname
query.from(community)
.join(community.account, account)
.join(account.accountProfile, accountProfile)
.where(predicate);
repository.findAll(query, pageable);
Hope that helps.
I found one solution as
QEntity qEntity1 = new QEntity("qEntity1");
QEntity qEntity2 = new QEntity("qEntity2");
so while querying you can use
new JPAQueryFactory(entityManager).from(qSampleBO)
.innerJoin(qEntity1).on(qEntity1.id.eq(qSampleBO.address.id))
.innerJoin(qEntity2).on(qEntity2.id.eq(qSampleBO.secondary_address.id))
...
