I have a project which is built from several maven modules. These modules include logic to clear down, populate and validate the contents of a PostgreSQL database.
The lower level modules all work fine, but my top level Spring Boot Application is currently failing due to the following error:

The stack trace is pointing me to this key line:
org.postgresql.util.PSQLException: ERROR: column userrecord0_.created_by_user_uuid does not exist
The test which fails is as follows:
#RunWith(SpringJUnit4ClassRunner.class)
#SpringApplicationConfiguration(classes = CornerstoneApplication.class)
#WebAppConfiguration
public class CornerstoneApplicationTest {
#Test
public void contextLoads() { }
}
The application is:
#SpringBootApplication
public class CornerstoneApplication {
public static void main(String[] args) {
SpringApplication.run(CornerstoneApplication.class, args);
}
}
Looking at the underlying data, the first data record in the userrecord file does not have a created_by_user_uuid, but looking at the entity record, this field is not mandatory
UserRecord:
#Entity
#Table(name = "users")
public class UserRecord extends AbstractKeyedRecord implements Record {
#Nonnull
#Column(unique = true)
private String userName;
#Nonnull
private String firstName;
#Nonnull
private String lastName;
<truncated>
AbstractKeyedRecord:
#MappedSuperclass
public abstract class AbstractKeyedRecord extends AbstractRecord {
#Id
#org.hibernate.annotations.Type(type = "pg-uuid")
private UUID id;
<truncated>
AbstractRecord:
#MappedSuperclass
public abstract class AbstractRecord implements Serializable, Record {
#Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTime")
private DateTime createdDate;
#org.hibernate.annotations.Type(type = "pg-uuid")
private UUID createdByUserUuid;
#Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTime")
private DateTime lastUpdatedDate;
#org.hibernate.annotations.Type(type = "pg-uuid")
private UUID lastUpdatedUserUuid;
public AbstractRecord() {
}
<truncated>
Record:
public interface Record {}
Probably the most frustrating thing of all is that I have had this working before, but recently moved from xml config files to use config classes, and the ApplicationTest has not worked since.
So, my question is can anyone suggest steps I could take to resolve resolve this issue ?
I think you are connecting to some other DB that doesn't have the 'created_by_user_uuid' column. Especially because it was working with XML config.
Check your database connection configuration. You could set the DB connection password to a wrong password to be sure that you are really connecting to the configured DB.

This is my enum:
public enum FooBarType {
Foo,
Bar;
#javax.persistence.Converter
public static class Converter implements AttributeConverter<FooBarType, String> {
#Override
public String convertToDatabaseColumn(FooBarType t) {
return t.toString();
}
#Override
public FooBarType convertToEntityAttribute(String s) {
for (FooBarType value : FooBarType.values()) {
if (value.name().equalsIgnoreCase(s)) {
return value;
}
}
throw new IllegalArgumentException("Invalid value for enum: " + s);
}
}
}
This is my Entity:
#Table
#IdClass(FooBar.PrimaryKey.class)
public class FooBar {
#Id
#Column(name = "id")
public String id;
#Id
#Column(name = "fooBarType")
#Convert(converter = FooBarType.Converter.class)
public FooBarType fooBarType;
#Column(name = "value")
public int value;
public static class PrimaryKey implements Serializable {
public String id;
public FooBarType fooBarType;
}
}
And my repository:
public interface FooBarRepository extends Repository<FooBar, FooBar.PrimaryKey> {
FooBar getByIdAndFooBarType(String id, FooBarType fooBarType);
}
This is the data in the database. I know the case of 'FOO' is wrong, but that's the part I'm trying to achieve: case-insensitive conversion.
+----------+--------------+---------+
| id | fooBarType | value |
+----------+--------------+---------+
| user-1 | FOO | 998 |
+----------+--------------+---------+
When I test the getByIdAndFooBarType("someId", FooBarType.Foo) method, this exception is thrown:

It seems that the Spring-data/hibernate query builder isn't honoring the #Convert attribute.
If I put the #Enumerated attribute, the #Convert attribute is ignored, and an expected exception is thrown. The exception basically says that it cannot map 'FOO' back to FooBarType (due to case-sensitivity).
org.springframework.dao.InvalidDataAccessApiUsageException: Unknown name value [FOO] for enum class [FooBarType]; nested exception is java.lang.IllegalArgumentException: Unknown name value [FOO] for enum class [FooBarType]

Update! This issue only affect composite primary keys
Regular columns work as expected with the #Converter annotation
You can't use Convert and Id annotations on same field, nor Convert and Enumerated. Use EmbeddedId instead as seen by #Converter documentation:
Note that Id attributes, version attributes, relationship attributes, and attributes explicitly annotated as Enumerated or Temporal (or designated as such via XML) will not be converted.
See: https://docs.oracle.com/javaee/7/api/javax/persistence/Converter.html, JSR-338, Chapter 11.1.10 Convert annotation, page 438.
For a really odd reason, if I went the route of using #Embeddable and #EmbeddedId of declaring the composite key (instead of using #IdClass), the #Convert annotation is honored.
It's a disconnect in behaviour, in my opinion.
Working code:
public enum FooBarType {
Foo,
Bar;
#javax.persistence.Converter
public static class Converter implements AttributeConverter<FooBarType, String> {
#Override
public String convertToDatabaseColumn(FooBarType t) {
return t.toString();
}
#Override
public FooBarType convertToEntityAttribute(String s) {
for (FooBarType value : FooBarType.values()) {
if (value.name().equalsIgnoreCase(s)) {
return value;
}
}
throw new IllegalArgumentException("Invalid value for enum: " + s);
}
}
}
Entity:
#Table
public class FooBar {
#EmbeddedId
public PrimaryKey compositeKey;
#Column(name = "value")
public int value;
#Embeddable
public static class PrimaryKey implements Serializable {
#Column(name = "id")
public String id;
#Column(name = "fooBarType")
#Convert(converter = FooBarType.Converter.class)
public FooBarType fooBarType;
}
}
And my repository:
public interface FooBarRepository extends Repository<FooBar, FooBar.PrimaryKey> {
FooBar getByCompositeKey(FooBar.PrimaryKey compositeKey);
}
You should try enumerated like that:
#Id
#Enumerated(EnumType.STRING)
#Column(name = "foobar")
public FooBarType fooBarType;
And you repository:
public interface FooBarRepository extends Repository<FooBar, FooBar.PrimaryKey> {
FooBar getByIdAndFooBarType(String id, FooBarType foobar);
}
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")
#Transactional
public class CustomerServiceImpl implements CustomerService {
#Autowired
private CustomerRepository customerRepository;
#Override
public void save(Customer customer) {
customerRepository.save(customer);
}
#Override
public List<Customer> findAll() {

}
#Override
public Customer findById(Long id) {

}
#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'm trying to retrieve data using my Hibernate One to Many relation but failing. I'm trying to get all Bookmarked_rooms from Account. Here is my query:
public RoomList findBookmarkedRooms(String name) {
Query query = em.createQuery("FROM Room r WHERE r.roomid in(SELECT Room_id FROM Bookmarked_rooms a )");
List rooms = query.getResultList();;
if (rooms.size() == 0) {
return null;
} else {
return new RoomList(rooms);
}
}
Here is my Account and Room entity given separately:
public class Account {
#Id
#GeneratedValue
private Long id;
#Column(name="username",unique=true,nullable=false)
private String username;
#OneToMany
#JoinTable(name = "Bookmarked_rooms", joinColumns = #JoinColumn(name="Account_id"), inverseJoinColumns = #JoinColumn(name="Room_id"))
private Collection<Room> bookmarkedroom = new ArrayList<Room>();
//Getters and Setters
}
Room entity:
public class Room {
#Id
#GeneratedValue
private long roomid;
#Column(name="roomname",unique=true,nullable=false)
private String roomname;
private String description;
//Getters and Setters
}
When I run the query I've following error:
java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: Bookmarked_rooms is not mapped [FROM web.core.models.entities.Room r WHERE r.roomid in(SELECT Room_id FROM Bookmarked_rooms a )]

I'm not understanding what is my actual error. If the error is my query, please some one demonstrate me the right query.
You could simply do it from the other end.
select markedroom from Account a
inner join a.bookmarkedroom markedroom
This could help you.
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:
java.lang.NullPointerException

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 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.
