Hibernate doesn't create table that implements Serializable interface?

I have small project with Spring Data, MVC and Web Flow. Also I have 2 entities that I use in Spring Web Flow, so they MUST implement Serializable interface, but I noticed that Hibernate doesn't create tables, that implement it, for proving it I just copied my entity, removed "implements Serializable" created new class and pasted the entity code there, the new table was created. How it works ? How to create table from entity that implement Serializable, is it possible at all ?
The entities code:
#Table(name = "users")
#Entity
public class User implements Serializable{
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "idUsers")
private int id;
#Column(name = "login")
#Size(min = 3, max = 15,message = "Неправильний розмір")
#NotEmpty(message = "Не може бути пустим!")
private String login;
#Size(min = 6, max = 21,message = "Неправильний розмір")
#NotEmpty(message = "Не може бути пустим!")
#Column(name = "password")
private String password;
#NotNull(message = "Не може бути пустим!")
#Column(name = "email")
private String email;
#Column(name = "photo")
private String path;
#Column(name = "about")
private String about;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
#OneToMany(
fetch = FetchType.EAGER,
mappedBy = "user",
cascade = CascadeType.ALL,
orphanRemoval = true
)
private Set<CommentsToBook> commentsToBooks;
public Set<CommentsToBook> getCommentsToBooks() {
return commentsToBooks;
}
public void setCommentsToBooks(Set<CommentsToBook> commentsToBooks) {
this.commentsToBooks = commentsToBooks;
}
public Set<BookOrder> getOrders() {
return orders;
}
public void setOrders(Set<BookOrder> orders) {
this.orders = orders;
}
#OneToMany(
fetch = FetchType.EAGER,
mappedBy = "user",
cascade = CascadeType.ALL,
orphanRemoval = true
)
private Set<BookOrder> orders;
public String getPath() {
return path;
}
public String getAbout() {
return about;
}
public void setAbout(String about) {
this.about = about;
}
public void setPath(String path) {
this.path = path;
}
public String getLogin() {
return login;
}
public void setLogin(String login) {
this.login = login;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
}
And the second one:
#Entity
#Table(name = "booook_order")
public class BookOrder implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "id")
private int id;
#Column(name = "bank_card")
private String bankCardId;
#Column(name = "user_name")
private String custName;
public User getUser() {
return user;
}
#ManyToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
#JoinTable(name = "book", joinColumns = {
#JoinColumn(name = "id")
},inverseJoinColumns = {#JoinColumn(name = "idlibrary")})
private Set<Book> booksList;
#Column(name ="novaposhta-vid")
private String NPVid;
public String getNPVid() {
return NPVid;
}
public void setNPVid(String NPVid) {
this.NPVid = NPVid;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
#Column(name = "city")
private String city;
public void setUser(User user) {
this.user = user;
}
#ManyToOne(cascade = CascadeType.ALL,
fetch = FetchType.EAGER)
#JoinColumn(name = "idUsers")
private User user;
public String getCustName() {
return custName;
}
public void setCustName(String custName) {
this.custName = custName;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public Set<Book> getBooksList() {
return booksList;
}
public void setBooksList(Set<Book> booksList) {
this.booksList = booksList;
}
public String getBankCardId() {
return bankCardId;
}
public void setBankCardId(String bankCardId) {
this.bankCardId = bankCardId;
}
}

Hibernate mappedBy and ManyToMany

I'm starting from scratch a new project and i got this problem which i cannot solve. I have three entities, and they all have a manytomany relationship with each other. There is the Cluster:
#Entity
#Component
#Table(name = "clusterEntity")
public class Cluster {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id", nullable = false, updatable = false)
private Long id;
#Column(name = "name")
private String name;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
#ManyToMany
#JoinTable(name="cluster_user",
joinColumns=#JoinColumn(name="cluster_id", referencedColumnName="id"),
inverseJoinColumns=#JoinColumn(name="user_id", referencedColumnName="id"))
private List<User> users_cluster;
#ManyToMany
#JoinTable(name="cluster_sito",
joinColumns=#JoinColumn(name="cluster_id", referencedColumnName="id"),
inverseJoinColumns=#JoinColumn(name="sito_id", referencedColumnName="id"))
private List<Sito> sitos;
#Override
public String toString() {
return "Cluster{" +
"id=" + id +
", name='" + name +
", users='" + users_cluster.toString() +
'}';
}
}
This is the User:
#Entity
#Component
#Table(name = "userEntity")
public class User {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id", nullable = false, updatable = false)
private Long id;
#Column(name = "email", nullable = false, unique = true)
private String email;
#Column(name = "password_hash", nullable = false)
private String passwordHash;
#Column(name = "role", nullable = false)
#Enumerated(EnumType.STRING)
private Role role;
#Column(name = "G1", nullable = true)
private String G1;
#Column(name = "G2", nullable = true)
private String G2;
#Column(name = "G3", nullable = true)
private String G3;
#Column(name = "G4", nullable = true)
private String G4;
#Column(name = "G5", nullable = true)
private String G5;
#Column(name = "G6", nullable = true)
private String G6;
#Column (name = "access_token", nullable = true)
private String access_token;
#Column (name = "refresh_token", nullable = true)
private String refresh_token;
public Long getId() {
return id;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPasswordHash() {
return passwordHash;
}
public void setPasswordHash(String passwordHash) {
this.passwordHash = passwordHash;
}
public Role getRole() {
return role;
}
public void setRole(Role role) {
this.role = role;
}
public String getG1() {
return G1;
}
public void setG1(String g1) {
G1 = g1;
}
public String getG2() {
return G2;
}
public void setG2(String g2) {
G2 = g2;
}
public String getG3() {
return G3;
}
public void setG3(String g3) {
G3 = g3;
}
public String getG4() {
return G4;
}
public void setG4(String g4) {
G4 = g4;
}
public String getG5() {
return G5;
}
public void setG5(String g5) {
G5 = g5;
}
public String getG6() {
return G6;
}
public void setG6(String g6) {
G6 = g6;
}
public String getAccess_token() {
return access_token;
}
public void setAccess_token(String access_token) {
this.access_token = access_token;
}
public String getRefresh_token() {
return refresh_token;
}
public void setRefresh_token(String refresh_token) {
this.refresh_token = refresh_token;
}
#ManyToMany(mappedBy="users_cluster")
private List<User> users_cluster;
#ManyToMany(mappedBy="users_sito")
private List<User> users_sito;
public User(){}
#Override
public String toString() {
return "User{" +
"id=" + id +
", email='" + email.replaceFirst("#.*", "#***") +
", passwordHash='" + passwordHash.substring(0, 10) +
", role=" + role +
'}';
}
}
This is the Sito:
#Entity
#Component
#Table(name = "sitoEntity")
public class Sito {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id", nullable = false, updatable = false)
private Long id;
#Column(name = "name")
private String name;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
#ManyToMany
#JoinTable(name="sito_user",
joinColumns=#JoinColumn(name="sito_id", referencedColumnName="id"),
inverseJoinColumns=#JoinColumn(name="user_id", referencedColumnName="id"))
private List<User> users_sito;
#Override
public String toString() {
return "Sito{" +
"id=" + id +
", name='" + name+
", users='" + users_sito.toString()+
'}';
}
}
When i try compiling with maven i get the following error about mappedBY, as if it was written on both side of the relation, but in fact it is written only on one side:
Caused by: org.hibernate.AnnotationException: Illegal use of mappedBy on both sides of the relationship: User.users_cluster
Anyone has any ideaof what am i doing wrong?

Clustor
As far as I can see the Cluster entity is annotated correctly except some kine of naming convention. Instead of
private List<User> users_cluster;
I would recommend using
private List<User> users;
The list contains users so it should be named to reflect that; good naming is the best documentation, (imo).
User
This entity seems to be correctly annotated but the references are wrong as they are self referencing. So the entity should be modified as follows if you want to create a many-to-many relationship between the thre entities:
public class User {
// ...
#ManyToMany(mappedBy="users")
private List<Cluster> clusters;
#ManyToMany(mappedBy="users")
private List<Sito> sitos;
// getters + setters
}
Sito
Here too I made a small modification as follows:
public class Sito {
// ...
#ManyToMany
#JoinTable(name="sito_user",
joinColumns=#JoinColumn(name="sito_id", referencedColumnName="id"),
inverseJoinColumns=#JoinColumn(name="user_id", referencedColumnName="id"))
private List<User> users;
#ManyToMany(mappedBy = "sitos")
private List<Cluster> clusters;
// getters + setters
}
Now your three entities should be related to each other as you desired.

need to save child without retrieve it in hibernate

I need to save the child table values without retrieve the values.

public Long getOrderNo() {
return orderNo;
}
public void setOrderNo(Long orderNo) {
this.orderNo = orderNo;
}
public Integer getTotalClothes() {

}
public void setTotalClothes(Integer totalClothes) {

}
public Integer getMensCloth() {

return womensCloth;
}
public void setWomensCloth(Integer womensCloth) {
this.womensCloth = womensCloth;
}
public Integer getOtherClothes() {

public void setDeliveryDate(Date deliveryDate) {
this.deliveryDate = deliveryDate;

return orderStatus;

}
Implementation:
Session session = sessionFactory.getCurrentSession();
long id = 1;
Query query = session.createQuery("from user where id =" + id);
User emp6 = (User) session.load(User.class, new Long(1));
User user = (User) query.uniqueResult();
List<WashingOrder> washingOrder = user.getOrderList();
washingOrder.add(order);
user.setOrderList(washingOrder);
session.save(user);
Long orderID = (long) 1;
return orderID;
Here if you check I am getting the order list first (user.getOrderList()) and then I am adding the new list and saving the user.
But I want to save the new order list of the user without retrieve the previous order list.
There is any possibility for the adding new order data without retrieve the previous order list of the particular user.

You need to change a mapping
public class User {
#OneToMany(mappedBy = "user", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
private List<WashingOrder> orderList;
}
public class WashingOrder {
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "user_id")
private User user;
}
Session session = sessionFactory.getCurrentSession();
User user = (User) session.load(User.class, 1L);
WashingOrder order = new WashingOrder();
order.setUser(user);
session.save(order);
You can try to use a fake User instead of loading
WashingOrder order = new WashingOrder();
order.setUser(new User(1L));
session.save(order);

Use join and subquery with criteria in hibernate

I searched lot. But can't find solution for my case. i want create hibernate criteria for following query.
SELECT * FROM patient as p1 LEFT OUTER JOIN (SELECT * FROM patient_caller_admin_map WHERE caller_admin_id='1') as pca ON p1.patient_id=pca.patient_id;
i went through the DetachedCriteria , Criteria and created the following things. But don't know how to use LEFT_JOIN by joining both.
DetachedCriteria inner=DetachedCriteria.forClass(PatientCallerAdminMap.class, "patientCallerAdmin");
Criteria cr1=this.sessionFactory.getCurrentSession().createCriteria(Patient.class,"patient");

Please help to solve this.

Maybe you can achieve this without using subquery so the query become simpler :
Criteria cr1=this.sessionFactory.getCurrentSession().createCriteria(Patient.class,"patient");
cr2=cr1.createCriteria("patientCallerAdminMaps ",CriteriaSpecification.LEFT_JOIN);
cr3= cr2.createCriteria("callerAdmin",CriteriaSpecification.LEFT_JOIN);
cr3.add(Restrictions.eq("id", "1"));
For the "select *" you can't do it with criteria. This criteria will return a list of Patient entity.
If really want * you will have to add alias on subcriteria and use Projection to select explicitly the fields that you want

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
