I am trying to use the #OneToMany relationship in my project but got the error: org.hibernate.AnnotationException: Illegal attempt to map a non collection as a #OneToMany, #ManyToMany or #CollectionOfElements: com.digitalProfile.digitalProfile.entity.Education.faculty.
I am using JDK 11
My Education.java model looks like this :
package com.digitalProfile.digitalProfile.entity;
import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.OneToMany;
import javax.persistence.OneToOne;
import javax.persistence.Table;
#Entity
#Table(name="Education")
public class Education extends BaseEntity {
private String name;
private String establishDateNepali;
private String establishDateEnglish;
#OneToOne

private double area;
private int teacherCount;
private int studentCount;
private int staffCount;
#OneToOne
private AcademicLevel academicLevel;
#OneToMany(mappedBy = "education", fetch = FetchType.LAZY,
cascade = CascadeType.ALL)
private Faculty faculty;
private String province;
private String district;
private String munvdc;
private String ward;
private String gauntole;
private String streetname;
private String city;
//getter setter
and Faculty.java look like this :
package com.digitalProfile.digitalProfile.entity;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;
#Entity

#JoinColumn(name = "education_id", nullable = false)
private Education education;
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
and base entity:
package com.digitalProfile.digitalProfile.entity;
import java.util.Date;
import javax.persistence.Column;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

private Date dateCreated;
#Temporal(TemporalType.TIMESTAMP)
#UpdateTimestamp
private Date dateUpdated;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public Date getDateCreated() {
return dateCreated;
}
public void setDateCreated(Date dateCreated) {
this.dateCreated = dateCreated;
}
public Date getDateUpdated() {
return dateUpdated;
}
public void setDateUpdated(Date dateUpdated) {
this.dateUpdated = dateUpdated;
}
}
You currently have defined your Education class to have a single reference variable to Faculty:
public class Education extends BaseEntity {
private Faculty faculty;
}
But if you want to have a OneToMany relationship From Education To Faculty that means that one Education object needs to have references to multiple Faculty objects. So you need to change your data structure so that your Education class can hold multiple references to Faculty objects.
This is usually done by defining the field as a Collection like List:
public class Education extends BaseEntity {
private List<Faculty> faculties;
}
If you are saying Education can have multiple faculties, then it should be defined as
#OneToMany(mappedBy = "education", fetch = FetchType.LAZY,
cascade = CascadeType.ALL)
private Set<Faculty> faculties;

I'm working with spring boot and thymeleaf as template engine, when i tried to use Spring JPA method findAllByPropertyTitleContainning, i had StackOverflowError

I am in the process of adding a DTO layer to a restful api. Before, the program used entity (Recipe and Ingredient) directly and now I added a new DTO layer in between (RecipeDTO IngredientDTO). However, the moment I made the change I started getting Null values from #RequestBody. Each recipe contains a list of Ingredients and it is the list of ingredients that are returning null values, the recipe by itself is returning fine.
The controller looks like this
package com.example.recipes.controller;
import com.example.recipes.DTO.RecipeDTO;
import com.example.recipes.Service.RecipeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

You can replace
#OneToMany(mappedBy = "recipeDTO")
private List<IngredientDTO> ingredientDTOs;
to
#OneToMany(mappedBy = "recipeDTO")
private List<IngredientDTO> ingredients;
Or adding
#JsonProperty("ingredients")
Example:
#JsonProperty("ingredients")
#OneToMany(mappedBy = "recipeDTO")
private List<IngredientDTO> ingredientDTOs;
The reason for null is because Jackson doesn't know how to deserialise your fields properly with different names.
In the json, the name is ingredients but, in the DTO, it is ingredientsDTO. Those 2 need to match.
You request
{
"name":"unique2",
"ingredients":[...]
here the name of array you are passing in Json is different in the entity you are using.
Your DTO
#OneToMany(mappedBy = "recipeDTO")
private List<IngredientDTO> ingredientDTOs;
The name of fields in JSON request and Entity must match.
Change the name of field private List<IngredientDTO> ingredientDTOs; to ingredients.
Whenever I am trying to save an object to my DB, I keep getting the error Column 'created_at' cannot be null.
Here is my audit model:
import com.fasterxml.jackson.annotation.JsonIgnore;
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import org.springframework.data.annotation.CreatedDate;
import org.springframework.data.annotation.LastModifiedDate;
import org.springframework.data.jpa.domain.support.AuditingEntityListener;

import java.io.Serializable;
import java.util.Date;
#MappedSuperclass
#EntityListeners(AuditingEntityListener.class)
#JsonIgnoreProperties(
value = {"createdAt", "updatedAt"},
allowGetters = true
)
public abstract class AuditModel implements Serializable {
#Temporal(TemporalType.TIMESTAMP)
#CreatedDate
#Column(name = "created_at", nullable = false, updatable = false)
#JsonIgnore
private Date createdAt;
#Temporal(TemporalType.TIMESTAMP)
#LastModifiedDate
#Column(name = "updated_at", nullable = false)
private Date updatedAt;
public Date getCreatedAt() {
return createdAt;
}
public void setCreatedAt(Date createdAt) {
this.createdAt = createdAt;
}
public Date getUpdatedAt() {
return updatedAt;
}
public void setUpdatedAt(Date updatedAt) {
this.updatedAt = updatedAt;
}
}
Here is an example of a model that extends it:
import com.fasterxml.jackson.annotation.JsonIgnore;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.lang.Nullable;
import javax.persistence.*;
import javax.validation.constraints.NotEmpty;
import javax.validation.constraints.NotNull;
import java.util.Set;
#Data
#AllArgsConstructor
#NoArgsConstructor
#Entity
public class Category extends AuditModel {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
#NotEmpty(message = "Item Name is required.")
private String categoryName;
#NotNull
private String categoryDescription;
#Nullable
#JsonIgnore
#OneToMany(mappedBy = "category", fetch = FetchType.LAZY, cascade = CascadeType.ALL)
private Set<Item> items;
public Category(String categoryName, String categoryDescription) {
this.categoryName = categoryName;
this.categoryDescription = categoryDescription;
}
And here is the temporary CommandLine bean that is performing some tests for me:
#Configuration
public class ItemConfig {
#Autowired
ItemRepository itemRepository;
#Autowired
CategoryRepository categoryRepository;
#Value("${STORE.ENV}")
private String env;
#Bean
CommandLineRunner itemRunner(ItemRepository itemRepository) {
return args -> {
System.out.println("true");
Category cueCategory = new Category
("Cues",
"This category contains all items relating to billiard cues. This includes yada, yadada, and yada."
);
categoryRepository.save(cueCategory);
Item item = new Item("Test Cue", 700, cueCategory);
itemRepository.save(item);
};
}
}
At first, I was creating a blank object then setting all the values with setters. I thought that maybe it all needed to happen in one fel-swoop for the created_at to register with a proper date, so I added some constructors. That still didn't work. Please let me know if you see anything glaring!
You can fix this issue by modifying your createdAt and updatedAt properties like below and also, modify your getter and setters.
#CreationTimestamp
#Column(name = "created_at", updatable = false)
private Timestamp createdAt;
#UpdateTimestamp
#Column(name = "updated_at")
private Timestamp updatedAt;
You should add #EnableJpaAuditing annotation.
import org.springframework.data.jpa.repository.config.EnableJpaAuditing;
// ...
#Configuration
#EnableJpaAuditing
public class ItemConfig {
// ...
}
I have a simple database with Universities and Students (see entities below)
University.java
import lombok.Getter;
import lombok.Setter;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Getter
#Setter
#Table(name = "university")
public class University {
#Id
#GeneratedValue
#Column(name = "university_id")
private long id;
#Column(name = "university_name")
private String name;
public University() {
}
public University(String name) {
this.name = name;
}
}
Student.java
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;
#Entity
#Getter
#Setter
#Table(name = "student")
public class Student {
#Id
#GeneratedValue
#Column(name = "student_id")
private long id;
#Column(name = "student_name")
private String studentName;
#JoinColumn(name="university_name")
private String studentUniversityName;
#ManyToOne
private University university;
public Student() {
}
public Student(String name, String studentUniversityName) {
this.name = name;
this.studentUniversityName = studentUniversityName;
}
}
My entities should join on the university_name column. I wrote the following unit test to verify this behavior.
#Test
void test1() {
final String UNIVERSITY_NAME = "U of A";
universityRepository.save(new University(UNIVERSITY_NAME));
studentRepository.save(new Student("Joe", UNIVERSITY_NAME));
Student joe = studentRepository.findAll().get(0);
assertNotNull(joe.getUniversity()); // <------ FAILING
}
It is failing the assertNotNull(joe.getUniversity()) statement, which seems to indicate that the tables did not join. The strange thing to me, is that the next test passes (when I explicity set the University on Joe. (The contents of the database are the same either way, but findAll() for this test seems to properly trigger a join
#Test
void test2() {
final String UNIVERSITY_NAME = "U of A";
University uni = new University(UNIVERSITY_NAME);
universityRepository.save(uni);
Student joe1 = new Student("Joe", UNIVERSITY_NAME);
joe1.setUniversity(uni);
studentRepository.save(joe1);
Student student = studentRepository.findAll().get(0);
assertNotNull(student.getUniversity());
}
I don't want to set the university on Joe (like in the second test) before I save him, because sometimes I want to save students and universities at different times in the code. I want to be able to save Joe with a null university and populate the field in the call to findAll()
Can someone help me modify my entities so that the first test can pass?
it's better to use id for joining, for example:
#ManyToOne
#JoinColumn(name = "university_id")
private University university;
i hope working :)
try doing this
public class Student {
#Id
#GeneratedValue
#Column(name = "student_id")
private long id;
#Column(name = "student_name")
private String studentName;
private String studentUniversityName;
#ManyToOne
#JoinColumn(name="studentUniversityName" ,
referencedColumn="name")
private University university;
public Student() {
}
public Student(String name, String studentUniversityName) {
this.name = name;
this.studentUniversityName = studentUniversityName;
}
}
public class University {
#Id
#GeneratedValue
#Column(name = "university_id")
private long id;
#Column(name = "university_name")
private String name;
public University() {
}
public University(String name) {
this.name = name;
}
}
I am creating one feeds table which has one to many mapping with comments and many to one mapping with users table. But when i am annotating the user_table field in my feeds entity as #ManyToOne i am getting error like #OneToOne or #ManyToOne on xxx references an unknown entity: java .util.Set but when i am annotating it with #ManyToMany it is not throwing any error and the table are getting created. Can anyone explain me why

You have a one-directional relationship:
#OneToMany(targetEntity = CommentsDo.class, fetch = FetchType.EAGER, cascade = CascadeType.ALL)
private List<CommentsDo> comments;
And hibernate doesn't know, which column to use to join those entities. The best would be to add relationship definition on child side. You need to specify #JoinColumn, something like:
#JoinColumn(name = "feeds_do_id")
private FeedsDo feedsDo;
in CommentsDo class. Instead of feeds_do_id there should be a foreign key.
