Why would you use a public interface within a java db entity? - java

I found this code snippet while looking at other projects and I was wondering on the benefit of having a public interface within a java pojo. Why should you use it as seen in the below example. Is the below use considered a best practice? Is there a catch with using an interface liek this?
#Data
#NoArgsConstructor
#Entity
#Table(name = "customer_mapping", schema = "billing")
public class CustomerMapping {
public interface createCustomerMapping {
}
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#JsonProperty("customerMappingId")
private Integer id;
#Column(length=10)
#NotNull(groups = { createCustomerMapping.class })
#NotEmpty(groups = { createCustomerMapping.class })
#Size(groups = { createCustomerMapping.class }, min = 4, max = 4)
private String issuerCode;
#Column(length=10)
#NotNull(groups = { createCustomerMapping.class })
#NotEmpty(groups = { createCustomerMapping.class })
private String offerCode;
#NotNull
private Long customerId;
#CreationTimestamp
private LocalDateTime createdTs;
private String createdBy;
#UpdateTimestamp
private LocalDateTime updatedTs;
private String updatedBy;
public CustomerMapping(String offerCode) {
this.offerCode = offerCode;
}
public CustomerMapping(String issuerCode, String offerCode) {
this.issuerCode = issuerCode;
this.offerCode = offerCode;
}
public CustomerMapping(String issuerCode, String offerCode, Long customerId) {
this.issuerCode = issuerCode;
this.offerCode = offerCode;
this.customerId = customerId;
}
}
From what I know an interface is used to define a contract so I'm familiar with the implementation in using it via a library of code or if two teams needs to co-operate. But in the above example, its unclear to me.

JOOQ + JPA entities

I'm new with JOOQ library and have one thing interesting me so much. I've implemented CRUD service on JOOQ at first and after that I've tried to avoid some duplicate code. For reach that goal I've added JPA repository and also added#Entity annotation to my generated by JOOQ class. And now I still want to use JOOQ for some cases (querying List using filter and sorting and pagination). But something went wrong and now after JOOQ makes a select request I can see nulls in my class's attributes.
I'm getting right count of entities by filter, but class's properties are null after mapping. Is that mapping wrong or I just could't use JOOQ and JPA together for this case?
My abstact class for all entities (as I said, for avoid duplicating code I've refactored some code and now use generics):
#MappedSuperclass
public abstract class AbstractServiceEntity {
private Integer id;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
}
My JPA class (generated by JOOQ):
/**
* This class is generated by jOOQ.
*/
#SuppressWarnings({ "all", "unchecked", "rawtypes" })
#Entity
#Table(schema = "ref", name = "account")
public class Account extends AbstractServiceEntity implements Serializable {
private static final long serialVersionUID = -162537472;
private Integer id;
private Integer transitId;
private Integer partnerId;
private String currencyCode;
private String descr;
private Long inCredit;
private Long balanceLimit;
private Long outCredit;
private LocalDateTime createdAt;
private LocalDateTime updatedAt;
private Integer transitPartnerId;
public Account() {}
public Account(Account value) {
this.id = value.id;
this.transitId = value.transitId;
this.partnerId = value.partnerId;
this.currencyCode = value.currencyCode;
this.descr = value.descr;
this.inCredit = value.inCredit;
this.balanceLimit = value.balanceLimit;
this.outCredit = value.outCredit;
this.createdAt = value.createdAt;
this.updatedAt = value.updatedAt;
this.transitPartnerId = value.transitPartnerId;
}
public Account(
Integer id,
Integer transitId,
Integer partnerId,
String currencyCode,
String descr,
Long inCredit,
Long balanceLimit,
Long outCredit,
LocalDateTime createdAt,
LocalDateTime updatedAt,
Integer transitPartnerId
) {
this.id = id;
this.transitId = transitId;
this.partnerId = partnerId;
this.currencyCode = currencyCode;
this.descr = descr;
this.inCredit = inCredit;
this.balanceLimit = balanceLimit;
this.outCredit = outCredit;
this.createdAt = createdAt;
this.updatedAt = updatedAt;
this.transitPartnerId = transitPartnerId;
}
And my method extracting entities from DB:
#Repository
#RequiredArgsConstructor
public class JooqAccountRepository {
private final DSLContext jooq;
public List<Account> findAll(Condition filterCondition, SortField[] sortFields, Integer partnerId, Integer limit, Integer offset) {
return jooq.selectFrom(ACCOUNT)
.where(ACCOUNT.PARTNER_ID.equal(partnerId))
.and(filterCondition)
.orderBy(sortFields)
.limit(limit)
.offset(offset)
.fetchInto(Account.class);
}
public Integer findAccountsCount(Integer partnerId) {
return jooq.selectCount().from(ACCOUNT)
.where(ACCOUNT.PARTNER_ID.equal(partnerId))
.fetchOne(0, Integer.class);
}
}
As a result of my searches - I've made a mistake with annotations in Account class. If you want use these frameworks together, you should use #Column on entity's properties or setting your jooq's codegen plugin in different way)

Why filter for Spring Data JPA Specification doesn't work?

I try select data from the table by a filter with Spring Data JPA Specification I think what my implementation is correct, But it doesn't work. Help me please understand my mistake and fix my example.
I have very strange SQL query in log :
select phone0_.id as id1_0_, phone0_.note as note2_0_, phone0_.number as number3_0_, phone0_.operator_login as operator4_0_, phone0_.operator_pass as operator5_0_, phone0_.operator_name as operator6_0_, phone0_.operator_url as operator7_0_, phone0_.reg_date as reg_date8_0_, phone0_.status as status9_0_ from phone phone0_ where 0=1 limit ?
In the end: where 0=1 it's crash my mind. Where did that come from?
Here I fill CriteriaBuilder if filter field not null. I expect to get correctly built Specification object and send it to findAll(Specifications.where(specification), Pageable p) method. But something incorrect.
My repo and specification impl:
public interface PhoneRepository extends CrudRepository<Phone, Integer>, JpaRepository<Phone, Integer>, JpaSpecificationExecutor<Phone> {
class PhoneSpecification implements Specification<Phone> {
private final #NonNull PhoneService.PhoneFilter filter;
public PhoneSpecification(#NonNull PhoneService.PhoneFilter filter) {
this.filter = filter;
}
#Override
public Predicate toPredicate(Root<Phone> root, CriteriaQuery<?> query, CriteriaBuilder cb) {
Predicate predicate = cb.disjunction();
if (nonNull(filter.getId())) {
cb.disjunction().getExpressions().add(cb.equal(root.get("id"), filter.getId()));
}
if (nonNull(filter.getNote())) {
cb.disjunction().getExpressions().add(cb.like(root.get("note"), filter.getNote()));
}
if (nonNull(filter.getNumber())) {
cb.disjunction().getExpressions().add(cb.like(root.get("number"), filter.getNumber()));
}
if (nonNull(filter.getStatus())) {
cb.disjunction().getExpressions().add(cb.like(root.get("status"), filter.getStatus()));
}
if (nonNull(filter.getOpName())) {
cb.disjunction().getExpressions().add(cb.like(root.get("operatorName"), filter.getOpName()));
}
if (nonNull(filter.getOpLogin())) {
cb.disjunction().getExpressions().add(cb.like(root.get("operatorAccLogin"), filter.getOpLogin()));
}
if (nonNull(filter.getOpPassword())) {
cb.disjunction().getExpressions().add(cb.like(root.get("operatorAccPassword"), filter.getOpPassword()));
}
if (nonNull(filter.getRegFrom()) && nonNull(filter.getRegTo())) {
cb.disjunction().getExpressions().add(cb.between(root.get("regDate"), filter.getRegFrom(), filter.getRegTo()));
}
return predicate;
}
}
}
This is service level:
#Service
public class PhoneService {
#Autowired
private PhoneRepository phoneRepository;
public Phone get(int id) {
Phone phone = phoneRepository.findOne(id);
return nonNull(phone) ? phone : new Phone();
}
public Page<Phone> list(#NonNull PhoneFilter filter) {
PhoneSpecification specification = new PhoneSpecification(filter);
return phoneRepository.findAll(Specifications.where(specification), filter.getPageable());
}
#Data
public static class PhoneFilter {
private Pageable pageable;
private Integer id;
private Timestamp regFrom;
private Timestamp regTo;
private String number;
private String opLogin;
private String opPassword;
private String opName;
private String status;
private String note;
}
}
And entity
#Entity
#Data
#NoArgsConstructor
#AllArgsConstructor
#Table(name = "phone")
#ToString(exclude = {"accounts"})
#EqualsAndHashCode(exclude = {"accounts"})
public class Phone {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
#OneToMany(mappedBy = "phone", cascade = CascadeType.DETACH)
private Collection<SocialAccount> accounts;
#Column(name = "reg_date")
private Timestamp regDate;
#Column(name = "number")
private String number;
#Column(name = "operator_url")
private String operatorUrl;
#Column(name = "operator_login")
private String operatorAccLogin;
#Column(name = "operator_pass")
private String operatorAccPassword;
#Column(name = "operator_name")
private String operatorName;
#Column(name = "status")
private String status;
#Column(name = "note")
private String note;
}
I find the mistake.
Method CriteriaBuilder.disjunction() this is factory and each time when I call him I got new Predicate object.
This implementation CriteriaBuilderImpl:
public Predicate disjunction() {
return new CompoundPredicate(this, BooleanOperator.OR);
}
Be careful with it.

Cannot deserialize from String value Spring-Boot Restful project

I'm working on a Spring Boot + Maven + Restful + Hibernate project! After creating the RestController for adding new Devices in database i'm getting this error:

Here is my first entity:

So when i'm trying to add a new device, i get the error i mentioned upper.I don't know what is causing this exception. When I try to add with post a new Protocol it's working, table is being created in the database correctly and I am getting the data correctly in GET request as well..Please help me, I'm new to springboot and restful... if some more information is required, please just inform me and i will post it! Thank you!
I tried to reproduce your problem: here, but everything works as expected.
I think it can be related with this bug.
You should try to reproduce bug with different jackson version.
EDIT:
One more thing: It looks like you try to construct Protocol instead of Device. Show us your deviceService, if you can.

Mapping hibernate entity with Jackson annotation

I'm working with Spring, hibernate and MySql but I have some problem with seralization of query result.
First in my entity I added #JsonManagedReference on Set structure (#OneToMany side) and #JsonBackReference on single object reference (#ManyToOne side) and it works but I wasn't be able to retrieve all needed information (for example #ManyToOne reference).
So i swapping #JsonBackReference on set structure and #JsonManagedReference on single object but I retrieve
No serializer found for class org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) ) (through reference chain: com.model.tablesField.TableUI["data"]->java.util.ArrayList[0]->com.domain.Car["carType"]->com.domain.CarType_$$_jvst744_f["handler"])
I tried also with #JsonIgnore on Set structure but it doesn't work for the same issues.
This is my spring configuration
private Properties getHibernateProperties() {
Properties properties = new Properties();
properties.put(PROPERTY_NAME_HIBERNATE_DIALECT, env.getRequiredProperty(PROPERTY_NAME_HIBERNATE_DIALECT));
// properties.put(PROPERTY_NAME_HIBERNATE_SHOW_SQL, env.getRequiredProperty(PROPERTY_NAME_HIBERNATE_SHOW_SQL));
properties.put(PROPERTY_NAME_HIBERNATE_FORMAT_SQL, env.getRequiredProperty(PROPERTY_NAME_HIBERNATE_FORMAT_SQL));
properties.put("hibernate.enable_lazy_load_no_trans",true);
return properties;
and this is part of one of my several entities:
/**

#Entity
#Table(name = "car", catalog = "ATS")
public class Car implements java.io.Serializable {
/**

}
one method that uses the query:
#Override
#RequestMapping(value = { "/cars/{idFleet}"}, method = RequestMethod.GET)
public #ResponseBody TableUI getCars(#PathVariable int idFleet) {
TableUI ajaxCall=new TableUI();
try {
ajaxCall.setData(fleetAndCarService.findCarsByIdFleet(idFleet));
return ajaxCall;
} catch (QueryException e) {
ErrorResponse errorResponse= ErrorResponseBuilder.buildErrorResponse(e);
LOG.error("Threw exception in FleetAndCarControllerImpl::addCar :" + errorResponse.getStacktrace());
return ajaxCall;
}
}
two class for the query:
public interface DefRdiRepository extends JpaRepository<DefRdi, Integer>{
//#Query("SELECT CASE WHEN COUNT(c) > 0 THEN true ELSE false END FROM DefRdi c WHERE c.parName = ?1 AND c.description= ?2")
//Boolean existsByParNameAndDescription(String parName, String description);
//Query method of spring, I put findBy and then the key of research
DefRdi findByParNameAndDescription(String parName, String description);
}
public interface CarRepository extends JpaRepository<Car, Integer>, CarRepositoryCustom {
//Query method of spring, I put findBy and then the key of research
List<Car> findByFleetIdFleet(int idFleet);
}
Where is my error? I don't want Set object but only the single reference. The problem is only when I serialize. Thanks
UPDATE:
I use #JSonIgnore on all set collectionts and Eager instead lazy ad all works fine, but is there a way to retrieve all the information only when I want, for example having two different query?
So it doesn't work
#Override
#Transactional
public List<Car> findByFleetIdFleet(int idFleet) {
List<Car> carList= carRepository.findByFleetIdFleet(idFleet);
for (Car car:carList){
Hibernate.initialize(car.getCarType());
Hibernate.initialize(car.getFleet());
}
return carList;
// return carRepository.findByFleetIdFleet(idFleet);
}
All collections need to be fetched eagerly when loading them from data base, in order to get serialized by Spring. Make sure you fetch them eagerly (e.g. FetchMode.JOIN). You could also swap #JsonManagedReference from wanted fields with #JsonIgnore to black listed fields, Spring automatically serialises every field without annotation.
Update:
Changing the data repository to something like that should work, I am not sure it compiles, but I think you will get the point:
#EntityGraph(value = "some.entity.graph", type = EntityGraph.EntityGraphType.FETCH)
#Query(
value = "SELECT c FROM Car c INNER JOIN FETCH c.acquisitions WHERE c.id = :idFleet"
)
public interface CarRepository extends JpaRepository<Car, Integer>, CarRepositoryCustom {
//Query method of spring, I put findBy and then the key of research
List<Car> findByFleetIdFleet(int idFleet);
}
For more information look at this post and read the official documentation.
Workaround:
There seems to be a workaround, however fetching those collections eager like shown above should have a positive performance impact, since there is no need for loading proxies afterwards. Also no open transactions are needed at controller level.

Spring MVC CrudRepository findByIn

I have a CrudRepository that is supposed to make a query with an array (findByIn). In my repository tests it works, but when I try to use the query in my service, it doesn't work. Could someone explain why it doesn't work? Here is my setup (excluding some code irrelevant to the question)
Database model:
#Entity
#Table(name="Place")
public class Place implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "placeId", nullable = false)
private Long placeId;
#Column(name = "owner", nullable = false)
private String owner;
public Long getPlaceId() {
return placeId;
}
public void setPlaceId(Long placeId) {
this.placeId = placeId;
}
public String getOwner() {
return owner;
}
public void setOwner(String owner) {
this.owner = owner;
}
}
Repository:
#Repository
public interface PlaceRepository extends CrudRepository<Place, Long> {
List<Place> findByPlaceIdIn(Long[] placeId);
}
Service (this is the part not working):
#Service
public class PlaceService {
#Autowired
private PlaceRepository placeRepository;
public List<Place> getPlaces(Long[] placeIds) {
return placeRepository.findByPlaceIdIn(placeIds);
}
}
The problem is that in my service placeRepository.findByPlaceIdIn(placeIds) returns 0 objects if placeIds contains more than one item. If placeIds contains just one item, the query works fine. I tried replacing return placeRepository.findByPlaceIdIn(placeIds) with this piece of code that does the query for every array item one by one (this actually works, but I'd like to get the query work as it should):
ArrayList<Place> places = new ArrayList<Place>();
for (Long placeId : placeIds) {
Long[] id = {placeId};
places.addAll(placeRepository.findByPlaceIdIn(id));
}
return places;
I know that the repository should work, because I have a working test for it:
public class PlaceRepositoryTest {
#Autowired
private PlaceRepository repository;
private static Place place;
private static Place place2;
private static Place otherUsersPlace;
#Test
public void testPlacesfindByPlaceIdIn() {
place = new Place();
place.setOwner(USER_ID);
place2 = new Place();
place2.setOwner(USER_ID);
place = repository.save(place);
place2 = repository.save(place2);
Long[] ids = {place.getPlaceId(), place2.getPlaceId()};
assertEquals(repository.findByPlaceIdIn(ids).size(), 2);
}
}
I also have another repository for other model, which also uses findByIn and it works fine. I can't see any relevant difference between the repositories. I thought it might offer some more details to show the working repository, so I included it below:
Database model:
#Entity
#Table(name="LocalDatabaseRow")
#JsonIgnoreProperties(ignoreUnknown=false)
public class LocalDatabaseRow implements Serializable {
public LocalDatabaseRow() {}
public LocalDatabaseRow(RowType rowType) {
this.rowType = rowType;
}
public enum RowType {
TYPE1,
TYPE2
};
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "id")
#JsonProperty("id")
private Long id;
#JsonProperty("rowType")
#Column(name = "rowType")
private RowType rowType;
public Long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public RowType getRowType() {
return rowType;
}
public void setRowType(RowType rowType) {
this.rowType = rowType;
}
}
Repository:
#Repository
public interface LocalDatabaseRowRepository extends CrudRepository<LocalDatabaseRow, Long> {
List<LocalDatabaseRow> findByRowTypeAndUserIdIn(RowType type, String[] userId);
}
try using a list instead :
findByPlaceIdIn(List placeIdList);
You have a typo in your code (the repository declaration in the service):
#Autowired
private placeRepository placeRepository;
Should be:
#Autowired
private PlaceRepository placeRepository;
