I keep getting org.hibernate.AssertionFailure: null identifier when trying to create an object. My classes are as follows:
public class User {
#Id
#Column(name = "user_id", nullable = false)
private String userId;
#OneToOne(cascade = CascadeType.ALL, optional = true, mappedBy = "user")
private UserDetail userDetail;
}
public class UserDetail {
#Id
#Column(name = "user_id", nullable = false)
private String userId;
#OneToOne(optional = false)
#PrimaryKeyJoinColumn
private User user;
}
#Service
public class UserDetailService {
#Autowired
private UserDetailRepository userDetailRepository;
public void create(UserDetail userDetail) {
userDetailRepository.saveAndFlush(userDetail);
}
}
And when I try to create a UserDetail:
String userId = "user";
User user = userService.findByUserId(userId);
UserDetail userDetail = new UserDetail();
userDetail.setUserId(userId);
userDetail.setUser(user);
user.setUserDetail(userDetail);
userDetailService.create(userDetail);
I get the exception

I was stuck with a very similar problem. It seems that saving the UserDetails first, while there are also changes to the User (user.setUserDetail(userDetail)), requires an explicitly set cascade mode.
Adding the CascadeType.ALL to the UserDetails #OneToOne definition fixed it for me.
In my case it works by setting the relationship to null. Looks like it loads it anyway using the #Id.
UserDetail userDetail = new UserDetail();
userDetail.setUserId(userId);
userDetailService.create(userDetail);
For me it helped to upgrade from 4.2.x version of Hibernate to 4.3.11. The exception does not show up anymore, looks like a bug that has been fixed.
In my case, save parent before, add parent to relationship field of child (child haven't id), after save child (id get from Parent Entity)
references:
https://www.baeldung.com/hibernate-identifiers
#Entity
public class UserProfile {
#Id
private long profileId;
#OneToOne
#MapsId
private User user;
// ...
}
#Test
public void whenSaveDerivedIdEntity_thenOk() {
User user = new User();
session.save(user);
UserProfile profile = new UserProfile();
profile.setUser(user);
session.save(profile);
assertThat(profile.getProfileId()).isEqualTo(user.getUserId());
}
I had a similar issue and I've managed to solve it.
Try this:
#OneToOne(cascade = CascadeType.MERGE, optional = false)
#PrimaryKeyJoinColumn(name = "user_id")
private User user;
From what I've been able to find out, when persisting UserDetail, Hibernate takes a different code path and an underlying merge() call is being made instead of persist(), as you have stated in your issue. One fix could be adding CascadeType.MERGE.
Please have in mind that this fix does have the effect that the underlying User could be updated.
Another possible fix could be to use Spring Data Persistable interface, that gives you control of determining if an object is a new object or not, making the repository save method take the correct path (merge or persist).

I'm working on projet with spring boot and I'm trying to count the number of comment on a book using the stored procedure in MyQSL.
The stored procedure returns an int value which is the number of comments.
Here is my stored procedure:
DROP PROCEDURE IF EXISTS countComments;
DELIMITER //
CREATE PROCEDURE countComments(IN idBook int, Out total int)
BEGIN
SELECT count(*) INTO total FROM comments WHERE id_book = idBook;
END //
DELIMITER ;
The comment entity:
#Entity
#Table(name="comment")
#NamedStoredProcedureQueries({
#NamedStoredProcedureQuery(
name = "countComments",
procedureName = "countComments",
parameters = {
#StoredProcedureParameter(name = "idBook",
mode = ParameterMode.IN,
type = Integer.class),
#StoredProcedureParameter(name = "total",
mode = ParameterMode.OUT,
type = Integer.class)
})
})
public class Comment implements Serializable{
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name="id_comment", nullable=false)
private int idComment;
#ManyToOne(fetch = FetchType.LAZY, optional = false)
#JoinColumn(name = "id_book", nullable = false)
private Book book;
//constructor
//setters and getters
}
I have used the service approach, this is my service that I call in the controller:
#PersistenceContext
private EntityManager entityManager;
public int countSeenByCollaborateur(int CollaborateurId) {
StoredProcedureQuery theQuery = entityManager
.createNamedStoredProcedureQuery("countSeenByCollaborateur");
theQuery.setParameter("idBook", BookId);
BigDecimal outCount = (BigDecimal) theQuery.getSingleResult();
return outCount.intValue();
}
Here is the error:

Can someone help me to solve that issue, and thanks in advance.
change the
BigDecimal outCount = (BigDecimal) theQuery.getSingleResult();
to
Integer outCount = (Integer) theQuery.getOutputParameterValue("total");
You are using theQuery.getResultList() but make sure the procedure is returning results. do you have select query in procedure. Check your if else conditions which cause select statement may not executing.
If you read the javadoc of StoredProcedureQuery, you will find:
The getOutputParameterValue methods are used to retrieve the values passed back from the procedure through INOUT and OUT parameters.
Which means your code should be something like:
StoredProcedureQuery theQuery = entityManager.createNamedStoredProcedureQuery("countComments");
theQuery.setParameter("idBook", bookId);
int total = ((Number) theQuery.getOutputParameterValue("total")).intValue();
return total;
I have got this issue when testing-
Provided id of the wrong type for class com.myapp.ibank.domain.Customer. Expected: class java.lang.Long, got class java.lang.String
And I honestly cant figure out why I have got this and what is actually happening. When I use it normally, like running on a local tomcat and saving it through a controller and then service, it works just fine. No errors. This behaviour makes no sense to me.
I am using JPA 2.1 with Hibernate as a provider.
Here is test code:
#RunWith(SpringJUnit4ClassRunner.class)
#WebAppConfiguration
#ContextHierarchy({
#ContextConfiguration(classes = RootConfig.class),
#ContextConfiguration(classes = WebConfig.class)
})
#Transactional
public class AccountRepositoryTest {
#Autowired
private WebApplicationContext wac;
#Autowired
private AccountRepository accountRepository;
#Autowired
private CustomerService customerService;
private MockMvc mockMvc;
#Before
public void setup() {
this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
Customer cus = new Customer();
cus.setFirstName("John");
cus.setLastName("Smith");
customerService.save(cus);
}
#Test
public void testSaveAccount() {
Account account = new Account();
account.setCustomer(customerService.findByName("John"));
account.setName();
account.setDebitCard(new DebitCard((long) 2000));
accountRepository.create(account);
}
#Test
public void testSavePremiumAccount() {
PremiumAccount premAccount = new PremiumAccount();
premAccount.setCustomer(customerService.findByName("John"));
premAccount.setName();
premAccount.setDebitCard(new DebitCard((long) 6000));
premAccount.setCreditCard(new CreditCard((long) 12000));
accountRepository.create(premAccount);
}
}
My Customer Entity (Short version):
#Entity
#DynamicUpdate
#Table(name = "customer")
public class Customer implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String firstName;
private String lastName;
#OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER, mappedBy = "customer")
//#JoinColumn(name="account_id", referencedColumnName="id")
#Nullable
#JsonManagedReference
private List<Account> Accounts = new ArrayList<Account>();
//private Address Address;
public Customer() {
}
public Customer(String firstName, String lastName, List<Account> accounts) {
this.firstName = firstName;
this.lastName = lastName;
this.Accounts = accounts;
}
And my repo:
#Repository("customerRepository")
public class CustomerRepositoryImpl implements CustomerRepository {
#PersistenceContext
private EntityManager em;
#Override
#Transactional
#NotNull
public void save(Customer customer) {
em.persist(customer);
em.flush();
}
#Override
public Customer findByName(String Name) {
return em.find(Customer.class, Name);
}
}
What do I miss, or is this a general bug with the hibernate that cant be avoided? I read somewhere that this is a typical bug.

return customerRepository.findByName(Name);
}
}
Your method is defined as
return em.find(Customer.class, Name);
EntityManager.find() takes the ID of an entity, and returns the entity that has that ID. The ID of Customer is a Long. It's not the name. You need a query to implement findByName().
I faced this problem and the cause was that I didn't specify 'Name' as an ID(a primary key) in my model. As a result the parameter I passed as Id was being compared with the system generated Id (hjid) of that Customer object, and ended up not finding the object with that system generated ID (which is long in type). So it is necessary to explicitly specify the desired primary key in the model.
I'm running into below exception while trying to persist Many-to-Many relationship. Any clues would be really appreciated. I'm using hibernate's #ManyToMany annotation as shown below.
If I remove houses from the construction entity and then persist it works ok. The problem occurs only when I say construction.setHouses(houses) before calling persist. And I have 3 tables: Construction, House, and Construction_houses. Where Construction_houses stores mapping between construction and house using their primary keys.
#ManyToMany(cascade = CascadeType.ALL)
#JoinTable(name="construction_houses",
joinColumns={#JoinColumn(name="construction_id", referencedColumnName = "id")},
inverseJoinColumns={#JoinColumn(name="house_id", referencedColumnName = "id")})
private List<House> houses = new ArrayList<>();

The stacktrace states:
Can not set java.lang.Long field com.construction.domain.House.id to [Ljava.lang.Object;
Unfortunately that message is not only given for setters, but for getters as well.
So the message tells you that it tries to read the field House.id not for an object of type House, but for an object of type Object[].
It seems that your houses is not a list of House objects, but of arrays - or it contains at least one such array.
If you call System.out.println(construction.getHouses()); right before you persist your construction you will find something like: ...[Ljava.lang.Object;#...
I have the following specification which is supposed to check if the Magazines of a File are in a list of Magazines under a Subscription:
public static Specification<File> getContainingMagazines(final long subscriptionId){
return new Specification<File>() {
#Override
public Predicate toPredicate(Root<File> root, CriteriaQuery<?> query, CriteriaBuilder cb) {
Subquery<Subscription> subscriptionSubquery = query.subquery(Subscription.class);
Root<Subscription> subscriptionRoot = subscriptionSubquery.from(Subscription.class);
ListJoin<Subscription, Magazine> subscriptionMagazineJoin = subscriptionRoot.join(Subscription_.magazines);
Path<Long> subscriptionIdPath = subscriptionRoot.get(Subscription_.id);
subscriptionSubquery.
select(subscriptionRoot).
where(cb.equal(subscriptionIdPath, subscriptionId));
ListJoin<File, Magazine> magazinesJoin = root.join(File_.magazines);
return cb.and(magazinesJoin.get(Magazine_.id).in(subscriptionMagazineJoin.get(Magazine_.id)));
}
};
}
And in my service I'm doing this:
public int findFilesWithSubscription(long subscriptionId) {
List<File> fileList = fileRepository.findAll(FileSpecs.getContainingMagazines(subscriptionId));
return fileList.size();
}
The entities involved are the following:
#Entity
#Table(name = "nim_file")
public class File
#ManyToMany(fetch = FetchType.LAZY)
#JoinTable(
name = "nim_file_magazines",
joinColumns = #JoinColumn(name = "file_id"),
inverseJoinColumns = #JoinColumn(name = "magazine_id")
)
private List<Magazine> magazines;
and
#Entity
#Table(name = "nim_subscription")
public class Subscription
#ManyToMany(fetch = FetchType.EAGER)
#JoinTable(name = "nim_subscription_magazines",
joinColumns = #JoinColumn(name = "subscription_id"),
inverseJoinColumns = #JoinColumn(name = "magazine_id")
)
private List<Magazine> magazines;
finally
#Entity
#Table(name = "nim_magazine")
public class Magazine
This last one is a lookup table pretty much.
Now I'm testing using DWR, because I couldn't find a better way to test quickly and so far there is no stack trace nor sql shown even though hibernate has setShowSql(true). I only get this message:
2300777 [http-bio-9090-exec-4] WARN o.d.dwrp.BaseCallMarshaller - --Erroring: batchId[2] message[java.lang.NullPointerException]
So my questions are these:
What am I doing wrong?
How can I test/debug specifications and/or predicates better than dwr so I can get stack traces and such?
Edit
Upon some move to a Junit test class I obtained the following stack trace:

I always found the Criteria API very cumbersome to use and it may generate horrible SQL statements even for trivial joins.
Try this HQL query instead:
select f
from File f
inner join f.magazines file_magazine
where exists (
select s
from Subscription s
inner join s.magazines subscr_magazine
where s.id = :subscription_id and subscr_magazine.id = file_magazine.id
)
While you can also check any/some/member of, those expressions can lead to very complicated SQL queries. Try the suggested sub-select and see how it goes.
I am not sure if this works but you can also use the with extra join clause:
select f
from File f
inner join f.magazines file_magazine
where exists (
select s
from Subscription s
inner join s.magazines subscr_magazine with subscr_magazine.id = file_magazine.id
where s.id = :subscription_id
)
For logging al SQL queries along with parameters you can set up a datasurce-proxy in front of your application data source.
I'm trying to get data with grouping from the database using Spring JPA, my classes are :
Employee.java
#Entity
#Table(name = "employee")
public class Employee implements Serializable{
#Id #GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;
#Column(nullable=false, unique=true)
private String name;
#Type(type="org.jadira.usertype.dateandtime.joda.PersistentLocalDateTime")
#Column(name="date_of_birth")
private LocalDateTime dateOfBirth;
private Double salary;
#Column(name="marital_status")
private String maritalStatus;
#DateTimeFormat(pattern="MM/dd/yyyy")
#Column(name="date_of_hire")
#Type(type="org.jadira.usertype.dateandtime.joda.PersistentLocalDateTime")
private LocalDateTime dateOfHire;
private String title;
#ManyToOne()
#JoinColumn(name="dpartment_id")
private Department department;
//security additions
#Column(nullable=false)
private String password;
#OneToMany(fetch=FetchType.EAGER, cascade=CascadeType.ALL)
#JoinColumn(name="employee_id")
private Set<Role> roles = new HashSet<>();
}
Department.java
#Entity
#Table(name = "department")
public class Department implements Serializable{
#Id #GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;
#Column(nullable=false, unique=true)
private String name;
#OneToMany(fetch=FetchType.EAGER, cascade=CascadeType.ALL) #JoinColumn(name="department_id")
private Set<Employee> employees = new HashSet<Employee>();
#OneToOne()
#JoinColumn(name="manager_id",nullable=true)
private Employee manager;
}
I'm trying to get the data from the sql query :
select Dep.id, Dep.name as department_name , sum(emp.salary) as total_salaries, count(emp.id) as employee_count, dep.manager_id from employee emp inner join department dep
on emp.department_id = dep.id
group by dep.id
I have tried the using
query= EntityManager .createQuery("select new com.me.domain.DepartmentSummary( d, sum(e.salary), count(e.id) ) "
+ " from Department d inner JOIN d.employees e group by d.id ");
List items = query.getResultList();
but this query.getResultList() for some reason crashes with a NullPointerException.
I'm not sure what I have done wrong or if there is any other way to do it.
Thanks in advance.

According to Hibernate docs:
Hibernate also does not currently expand a grouped entity, so you
cannot write group by cat if all properties of cat are non-aggregated.
You have to list all non-aggregated properties explicitly.
So in your case, you'd have to include all Department properties in the group by clause.
