The project crashes for one simple reason - it does not see the table (it seems to me), maybe the problem is in the #Table annotation
#Entity
#Table(name = "user")
#JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})
public class User extends BaseEntity<Long> {
public enum Roles {
ADMIN
}
private String firstName;
private String lastName;
#Column(name = "username")
private String username;
#Convert(converter = PurshasedProductConverter.class)
private List<PurshasedProduct> purshasedProducts;
private String email;
private String activationCode;
#Convert(converter = AttachmentConverter.class)
private Attachment userAvatar;
public Attachment getUserAvatar() {
return userAvatar;
}
public void setUserAvatar(Attachment userAvatar) {
this.userAvatar = userAvatar;
}
#JsonProperty(access = Access.WRITE_ONLY)
private String password;
#JsonProperty(access = Access.WRITE_ONLY)
private String temporaryPassword;
#Convert(converter = StringArrayConverter.class)
private String[] roles;
private Date lastPasswordReset;
private Date dateCreated;
private Date dateUpdated;
private Date validatyTime;
private Boolean active;}
I used to have #Table (name = "\" user \ ""), but this created a lot of other problems for me, now as you see in the code, but it doesn't work. Here is the error itself Caused by: org.postgresql.util.PSQLException: ERROR: column user0_.id does not exist
some advise adding schema to the table annotation, but this does not help me
I also faced this problem and including schema name in my #Table annotation solved the problem:
#Table(name = "user", schema="mySchema")

I'm using Hibernate in my spring project. But It doesn't work for One-To-One relationships. It gives me the below error.
Unable to build Hibernate SessionFactory; nested exception is org.hibernate.MappingException: Could not determine type for: com.example.TransfertNational.model.Client, at table: ComptePaiement, for columns: [org.hibernate.mapping.Column(client)]
I have ran some searches in the internet, but it doesn't work for me.
the Client Entity :
#Data #Entity
#AllArgsConstructor #NoArgsConstructor #ToString
public class Client {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private int id;
private String typeTransfert;
private String typePiece;
private String cin;
private String sexe;
private String prenom;
private String typePieceIdentite;
private String paysEmission;
private String numPI;
private String validitePI;
private String dateNaissance;
private String profession;
private String nationalite;
private String paysAdresse;
private String adresseLegale;
private String ville;
private String gsm;
private String email;
#OneToMany(fetch = FetchType.LAZY,
cascade = CascadeType.ALL)
private Set<Beneficiaire> beneficiares;
#OneToOne(fetch = FetchType.LAZY,
cascade = CascadeType.ALL)
private ComptePaiement comptePaiement;
}
the ComptePaiement Entity :
#Data
#Entity
#AllArgsConstructor
#NoArgsConstructor
#ToString
public class ComptePaiement {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private int id;
private String solde;
private String rip;
private Client client;
}
Answer from comments:
You are probably missing #JoinColumn on Client or ComptePaiement and mappedBy in #OneToOne annotation, depending which will hold reference id in database.
Today I came across a weird bug while trying to test a JPA update query and I'm wondering if this a SpringBoot bug.
I have the following entities
An Entry entity
#Entity
#Data
#AllArgsConstructor
#NoArgsConstructor(access = AccessLevel.PROTECTED, force = true)
public class Entry {
#Id
private String id;
#ManyToOne(targetEntity = User.class)
#JoinColumn(referencedColumnName = "username")
#NotNull
private final User username;
#Enumerated(EnumType.STRING)
#NotNull
private Type type;
#ManyToOne(targetEntity = Category.class)
#JoinColumns({#JoinColumn(referencedColumnName = "name"),#JoinColumn(referencedColumnName = "type"),#JoinColumn(referencedColumnName = "username")})
#NotNull
private Category category;
#Size(max = 45)
#NotBlank
private String description;
#NotNull
private Double amount;
#NotNull
private final Date createdAt;
private Timestamp lastUpdate;
#NotNull
private Boolean isDeleted;
public enum Type{
Income,Expense
}
}
A Category entity with a composite key
#Entity
#NoArgsConstructor(access = AccessLevel.PROTECTED, force = true)
#Setter
#Getter
#EqualsAndHashCode(of = {"id"})
#ToString(of = {"id"})
public class Category {
#EmbeddedId
private CategoryId id;
private final Timestamp createdAt = Timestamp.from(Instant.now());
#ManyToOne(targetEntity = User.class)
#JoinColumn(referencedColumnName = "username")
private final User user;
#OneToMany(cascade = CascadeType.ALL,mappedBy = "category")
private List<Entry> entries;
public Category(String name, Type type, User user){
this.id = new CategoryId(name,type,user.getUsername());
this.user = user;
}
}
A CategoryID that is the embeddable composite key of the Category entity
#Data
#Embeddable
#AllArgsConstructor
#NoArgsConstructor(access = AccessLevel.PROTECTED)
#EqualsAndHashCode(of = {"name","type","username"})
public class CategoryId implements Serializable {
private String name;
#Enumerated(EnumType.STRING)
private Type type;
private String username;
}
The following repository
#Repository
public interface EntryRepository extends JpaRepository<Entry, String> {
Optional<Entry> findEntryById(String id);
#Modifying(clearAutomatically = true, flushAutomatically = true)
#Query(value = "UPDATE Entry e SET e.username = :username, e.type = :type, e.category = :category, e.description = :description, e.amount = :amount, e.createdAt = :date, e.lastUpdate = :lastUpdate, e.isDeleted = :isDeleted WHERE e.id = :id")
void update(#Param("id") String id,
#Param("username") User username,
#Param("type") Entry.Type type,
#Param("category") Category category,
#Param("description") String description,
#Param("amount") Double amount,
#Param("date") Date date,
#Param("lastUpdate") Timestamp lastUpdate,
#Param("isDeleted") Boolean isDeleted);
}
And finally the following Unit Test
#Test
void update() {
//given
User testUser = userRepository.save(new User("testUser#test.com","000000000000000000000000000000000000000000000000000000000000"));
Category testCategory = categoryRepository.save(new Category("Test Category", Entry.Type.Income,testUser));
Entry testEntry = new Entry("testEntry",testUser, Entry.Type.Income,
testCategory, "test",
0.0, new Date(343), from(now()), false);
System.out.println(testCategory);
entryRepositoryUnderTest.save(testEntry);
//when
entryRepositoryUnderTest.update("testEntry",testUser,Expense,testCategory,"testUpdated",1.0,new Date(346), from(now()),true);
Optional<Entry> actual = entryRepositoryUnderTest.findEntryById("testEntry");
System.out.println(actual.get().getCategory());
//then
assertThat(actual.get().getUsername()).isEqualTo(testUser);
assertThat(actual.get().getType()).isEqualTo(Expense);
assertThat(actual.get().getCategory()).isEqualTo(testCategory);
assertThat(actual.get().getDescription()).isEqualTo("testUpdated");
assertThat(actual.get().getAmount()).isEqualTo(1.0);
assertThat(actual.get().getIsDeleted()).isEqualTo(true);
}
When I run the test it fails and I get the following error message:
could not execute update query; SQL [update entry set username_username=?, type=?,category_name=?=category_type=?, description=?, amount=?, created_at=?, last_update=?, is_deleted=? where id=?]; nested exception is org.hibernate.exception.DataException: could not execute update query
As you can see here when SpringBoot is trying to produce a SQL query statement from my #Query parameter it can not properly extract the Category field from the parameters and inject it's composite embeddable key into the SQL statement. It has no problem extracting the User parameter because the User is an entity with an id that is not composite.
Is this a SpringBoot bug or am I missing something?
EDIT:
This is the structure of the database
I am new to Hibernate and JPA. I have several entities, each of which contains following four columns:
1. created_by
2. last_modified_by
3. created_date
4. last_modified_date
I would like these columns to get auto-populated while saving the associated entity.
Two sample entities are as follows:
Entity 1:
#Entity
#Table(name = "my_entity1")
#Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
public class MyEntity1 implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
#Column(name = "name")
private String name;
#Column(name = "created_by")
private String createdBy;
#Column(name = "last_modified_by")
private String lastModifiedBy;
#Column(name = "created_date")
private Instant createdDate;
#Column(name = "last_modified_date")
private String lastModifiedDate;
}
Entity 2:
#Entity
#Table(name = "my_entity2")
#Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
public class MyEntity2 implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
#Column(name = "description")
private String description;
#Column(name = "created_by")
private String createdBy;
#Column(name = "last_modified_by")
private String lastModifiedBy;
#Column(name = "created_date")
private Instant createdDate;
#Column(name = "last_modified_date")
private String lastModifiedDate;
}
In this context, I have gone through following posts: How to autogenerate created or modified timestamp field?, How can you make a created_at column generate the creation date-time automatically like an ID automatically gets created?.
I am getting how to capture the dates fields but I cannot understand how to capture created_by and last_modified_by.
Auditing Author using AuditorAware and Spring Security...
To tell JPA about currently logged in user we will need to provide an
implementation of AuditorAware and override getCurrentAuditor()
method. And inside getCurrentAuditor() we will need to fetch currently
logged in user.
Like this:
public class AuditorAwareImpl implements AuditorAware<String> {
#Override
public String getCurrentAuditor() {
return "TestUser";
// Can use Spring Security to return currently logged in user
// return ((User) SecurityContextHolder.getContext().getAuthentication().getPrincipal()).getUsername()
}
}
Now enable jpa auditing by using #EnableJpaAuditing
#Configuration
#EnableJpaAuditing(auditorAwareRef = "auditorAware")
public class JpaConfig {
#Bean
public AuditorAware<String> auditorAware() {
return new AuditorAwareImpl();
}
}
Look at this to get more details....
I have a parent class that has some shared fields and a child class that extends it.
#SuperBuilder(toBuilder = true)
#Data
public abstract class MultiTenantAuthoredDocument {
#Indexed
private String tenantId;
#CreatedDate
private LocalDateTime createdDate;
#LastModifiedDate
private LocalDateTime lastModifiedDate;
}
#Document(collection = "users")
#SuperBuilder(toBuilder = true)
#Data
#EqualsAndHashCode(callSuper = true)
#ToString(callSuper = true)
public class User extends MultiTenantAuthoredDocument {
#Id
private String id;
private String firstName;
private String lastName;
#Indexed
private String password;
#Indexed(unique = true)
private String userName;
#Indexed(unique = true)
private String email;
#Indexed
private List<UserRole> roles;
#Builder.Default
private boolean enabled = false;
}
However when running my unit tests, I get an unexpected exception when I do a findById and there's a result found namely:
No property b found on entity class be.moesmedia.erp.users.domain.User to bind constructor parameter to!
As I have no clue where property b is coming from it's pretty difficult to see what I'm doing wrong.
If anyone can help me point out what I'm doing wrong.
So I've figured out what was going wrong, Lombok generated a constructor that accepted an Object with the properties for the SuperBuilder class. Once I added #NoArgsConstructorto both the child and parent class, it works like a charm.
I have the following classes: DepartmentMember and Account, mapped by a OneToOne relationship.
This is the DepartmentMember class:
#Entity(name="departmentmember")
#Table(name="departmentmember")
#Embeddable
public class DepartmentMember {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
#Column(name="name", nullable=false)
private String nume;
#Column(name="lastName", nullable=false)
private String prenume;
#OneToOne(mappedBy="departmentMember",cascade=CascadeType.ALL,fetch=FetchType.LAZY, optional=false)
#JsonIgnore
private Account account;
public DepartmentMember() {}
public DepartmentMember(String nume, String prenume, String cNP, String email) {
super();
this.nume = nume;
this.prenume = prenume;
}
//getters and setters
}
And this is the Account class :
#Entity(name="users")
#Table(name="users")
public class Account {
#Id
private int id;
#Column(name="username", unique=true, nullable=false)
private String username;
#Column(name="password", nullable = false)
private String password;
#Column(name="authorities", nullable=false)
private String authorities;
#OneToOne(fetch=FetchType.EAGER)
#MapsId
#Embedded
private DepartmentMember departmentMember;
public Account() {}
public Account(String username, String password, String authorities) {
super();
this.username = username;
this.password = password;
this.authorities = authorities;
}
//getters and setters
}
I have defined an interface AccountRepository which extends the CrudRepository interface provided by Spring JPA.
What I want to do is define a query, which takes as a parameter a DepartmentMember id and retrieves the associated account for that member. Now this is how an Account object looks like:
{
"username": "Maria_Popescu",
"password": "4ec38c6e-2463-4562-99ba-9f6c2b4528c4",
"authorities": "ROLE_USER",
"departamentMember": {
"id": 2,
"nume": "Popescu",
"prenume": "Maria",
}
I tried using the findOne(int id) method, but it didn't work, so which is the correct approach to solve this?
Edit:
In the AccountRepository I have defined the following method :
Account findByDepartmentMemberId(int id) and I still get a not found error.
There was actually another problem in my controller. I managed to get it working by adding
Account findByDepartmentMemberId(#Param("id")int id);
in the AccountRepository
