I have two entities Institute and the InstituteVerificationStatus. I want to make the Institute as a Primary key for the InstituteVerificationStatus Entity. I add #Id annotation, but it is giving me an error.
The InstituteVerficationStatus Class doesn't have ID class.
Institute:
#Entity
#Table(name="Institute")
public class institute implements Serializable {
/**
*
*/
private static final long serialVersionUID = 617543973484435246L;
#Id
#Column(name = "id")
private String id;
#Column(name = "vendorId")
private String vendorId;
#Column(name = "name")
private String name;
#Column(name = "profilePicPath")
private String profilePicPath;
#Column(name = "contactNumber")
private String contactNumber;
#Column(name = "email")
private String email;
#Column(name = "gstNo")
private String gstNo;
#Column(name = "address")

#OneToOne(mappedBy = "institute")
private instituteVerificationStatus instituteVerificationStatus;
}
InstituteVerificationStatus:

#Column(name="status")

#Column(name="verificationTs")
private Timestamp verificationTs;
public instituteVerificationStatus(institute institute) {
this.institute = institute;
this.status='N';
}
public institute getInstitute() {
return institute;
}
public void setInstitute(institute institute) {
this.institute = institute;
}
public String getVerifiedByUserId() {
return verifiedByUserId;
}
public void setVerifiedByUserId(String verifiedByUserId) {
this.verifiedByUserId = verifiedByUserId;

this.status = status;
}
public Timestamp getVerificationTs() {
return verificationTs;
}
public void setVerificationTs(Timestamp verificationTs) {
this.verificationTs = verificationTs;
}
}
Try using the MapsId like below and add id which has the same data structure like the first entity's id, it will work fine.

I have three Entities in my Spring-Boot Application:
Recipe N->1 RecipeIngredient 1->N Ingredient
It corresponds to a many to many relationship. However, the RecipeIngredient has an extra field "quantity".
I am trying to link together my table so that I can get a Recipe with its ingredients and their quantities.
So far I have this code:
Recipe
#Data
#Entity
#Table(name="recipe")
public class Recipe implements Serializable {
#Id
#Column(name="id")
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
#Column(name="name")
private String name;
#Column(name="duration")
private int duration;
#Column(name="created_on")
private LocalDate created_on = LocalDate.now();
#Column(name = "preparation")
private String preparation;
#Column(name = "difficulty")
private int difficulty;
#Column(name = "serving")
private int serving;
#Column(name = "pricing")
private int pricing;
#JsonManagedReference("recipe")
#OneToMany(mappedBy = "recipe",cascade = CascadeType.ALL, fetch = FetchType.LAZY)
private List<RecipeIngredient> ingredients = new ArrayList<>();
public Recipe() {
}
public Recipe(String name, int duration, LocalDate created_on, String preparation, int difficulty, int serving, int pricing) {
this.name = name;
this.duration = duration;
this.created_on = created_on;
this.preparation = preparation;
this.difficulty = difficulty;
this.serving = serving;
this.pricing = pricing;
}
}
Ingredient
#Data
#Entity
#Table(name = "ingredient")
public class Ingredient implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id")
private int id;
#Column(name = "name")
private String name;
#JsonManagedReference("ingredient")
#OneToMany(mappedBy = "recipe", cascade = CascadeType.ALL)
private List<RecipeIngredient> recipeIngredients = new ArrayList<>();
public Ingredient() {
}
public Ingredient(int id, String name, List<RecipeIngredient> recipeIngredients) {
this.id = id;
this.name = name;
this.recipeIngredients = recipeIngredients;
}
}
RecipeIngredient
#Entity
#Table(name = "recipe_ingredient")
#Data
public class RecipeIngredient implements Serializable {
#EmbeddedId
public RecipeIngredientId recipeIngredientId = new RecipeIngredientId();
#JsonBackReference("recipe")
#ManyToOne(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
#MapsId("recipe_id")
private Recipe recipe;
#JsonBackReference("ingredient")
#ManyToOne(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
#MapsId("ingredient_id")
private Ingredient ingredient;
#Column(name="quantity")
private String quantity;
public RecipeIngredient() {
System.out.println("[RecipeIngredient] no args constructor called");
}
public RecipeIngredient(Recipe recipe, Ingredient ingredient, String quantity) {
this.recipe = recipe;
this.ingredient = ingredient;
this.quantity = quantity;
}
}
And finally RecipeIngredientId
#Embeddable
public class RecipeIngredientId implements Serializable {
private static final long serialVersionUID = 1L;
private int recipe_id;
private int ingredient_id;
public RecipeIngredientId() {
}
public RecipeIngredientId(int recipe_id, int ingredient_id) {
this.recipe_id = recipe_id;
this.ingredient_id = ingredient_id;
}
public int getRecipe_id() {
return recipe_id;
}
public void setRecipe_id(int recipe_id) {
this.recipe_id = recipe_id;
}
public int getIngredient_id() {
return ingredient_id;
}
public void setIngredient_id(int ingredient_id) {
this.ingredient_id = ingredient_id;
}
#Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
RecipeIngredientId that = (RecipeIngredientId) o;
return recipe_id == that.recipe_id &&
ingredient_id == that.ingredient_id;
}
#Override
public int hashCode() {
return Objects.hash(recipe_id, ingredient_id);
}
}
In my browser, can request all recipe and I obtain the following:
Ideally, I would like to obtain ingredients like:
...
"ingredients": [
{
"name": "salad",
"quantity: 2
}
]
Finally, is it possible with Spring / Hibernate to create a new Recipe, and add it new ingredients in a single request ? Or should I create the ingredients first and then pass them to the recipe ?
I'm trying to implement a unidirectional many to many relationship between entities with spring+JPA.
After a few tries changing hibernate versions I don't know whats the cause

I've also tried to make this relationship bidirectional and it didn't work, so I may be missing something
Also before this I had achievement objects instead of achievementId on joinedUserAchievement, it worked but I think its not what I need, I don't need to get every achievement object always, with only the id is fine.
From the docs:
Relationship mappings defined within an embedded id class are not supported
You should put the ids only in JoinedUserAchievementId, and put User and Achievement associations in JoinedUserAchievement directly like so:
public class JoinedUserAchievementId {
private Long userId;
private Long achievementId;
...
}
public class JoinedUserAchievement {
#EmbeddedId
private JoinedUserAchievementId joinedUserAchievementId;
#ManyToOne
#MapsId("userId")
#JoinColumn(name = "USER_ID")
private User user;
#ManyToOne(optional = false, fetch = LAZY)
#MapsId("achievementId")
#JoinColumn(name = "ACHIEVEMENT_ID")
private Achievement achievement;
//if you absolutely need to map the achievement_id column here as well
//note that it will already be mapped to joinedUserAchievementId.achievementId
#Column(name = "ACHIEVEMENT_ID", insertable=false, updatable=false)
private Long achievementId;
...
}
Remember to update the User.joinedUserAchievementList mapping to mappedBy="user".

"description":"","param":"smalltext","maxlength":20,"dependency":"",
my database has only one row inserted. and on my controller there is only one list of questions found. but whenever json output is thrown it repeats a lot of same rows like in the above json sample.
what might be the problems? if you can't find the complete solution can you please suggest me the reason behind the duplication of the same values in json format?
Jackson is getting in a loop here. Your Questions class has a link to Answers and that class refers back to Questions.
Solution
Mark the questions field or the getter in the Answers class as #JsonIgnored.
You can try #JsonManagedReference and #JsonBackReference annotations
For Jackson to work well, one of the two sides of the relationship should not be serialized, in order to avoid the infite loop that causes your stackoverflow error.
#OneToMany(mappedBy = "questions",targetEntity = Answers.class, cascade = CascadeType.ALL)
#JsonManagedReference
private Set<Answers> answers = new HashSet<>();
#ManyToOne(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
#JoinColumn(name = "ques_id", nullable = false)
#JsonBackReference
private Questions questions;
Or
If not interested in getting some entity data just use #JsonIgnore in any one of the class

The problem with your code is that you want to put a DoCustomer in a Customer container. It only works if DoCustomer is a subclass of Customer.
Edit 1: You could use BeanUtils to convert a DoCustomer into a Customer. Here is a good tutorial.
Do you mean:
custMap.putAll(newMap)
As everyone else has pointed out, we need to know what DoCustomer is to be able to help.
But, from what you have given us, I'd suggest casting each DoCustomer to a Customer or, more correctly, making a new Customer from the fields of each DoCustomer.
Something like:
custMap.put(cust.getKey(), new Customer(cust.getValue().getId(), cust.getValue().getCustName(), and so on..));
inside your for loop.
I can see the customer class defined you have provided doesn't have a constructor, so naturally you would have to add one to it
