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<>();
Exception:
org.hibernate.PropertyAccessException: could not get a field value by reflection getter of com.construction.domain.House.id

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've following query which is working fine on mysql. The same I wanted to implement through the spring-data-jpa querydsl API.
select c.* from orders o, customers c where o.customerNumber=103 and c.customerNumber=103;
CustomerRepository.java
public interface CustomerRepository extends JpaRepository<Customer, Integer>,
QueryDslPredicateExecutor<Customer>{
#Query("select c from Customer c where c.country='USA'")
List<Customer> findByCountry();
#Query("select c from Order o, Customer c where o.customerNumber=:customerNumber and c.customerNumber=:customerNumber")
List<Customer> findByCustomerNumber(#Param("customerNumber") Integer customerNumber);
}
But when I run the code, I see following error comes:

#Query("select c from Customer c where c.orders.customerNumber=:customerNumber and c.customerNumber=:customerNumber")
You try to access the customerNumerattributein Order, but I do not see an attribute called customeNumber. You only have a orderNumber.
#Query("select c from Customer c, Order o where o.customer.customerNumber=:customerNumber and c.customerNumber=:customerNumber")
But I am not that sure what you actually want to achieve. Do you want all orders by a customer?
I use spring boot .Testing the jpa oneTone Bidirectional.

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.

Customer Service Impl:
#Service("customerService")

public class CustomerServiceImpl implements CustomerService {
#Autowired
private CustomerRepository customerRepository;
#Override
public void save(Customer customer) {
customerRepository.save(customer);
}
#Override

#Override

}
}
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 have been trying to query data from tow tables in spring JPA but with no luck,
when i call the EntityManager.createQuery("").getResultList() a null pointer exception is triggered with the provided callstack at the bottom, i have the classes :

Actually, the problem was incompatibility between hibernate jars version and spring JPA jars version. after updating my maven with the latest spring and hibernate versions everything worked well. i hope this might help anybody in the future.
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.
Update:
test case callstack :
java.lang.NullPointerException

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.
