Data insertion in database using jpa issueing error

I am new to the JPA world. Here I have tried to make a simple POS. The problem is that when there is no predefined value in tables although the PK is auto-incremented, data is not being inserted into DB. But if I set a predefined row into the tables then there are no issues and data is being inserted successfully. please help me.
The following are my Java classes, and I am using Mysql for DB.

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")

#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() {

ModelMapper fail to convert java.util.list to java.util.list on DeleteMapping

good day everyone,
i have this project where i use the ModelMapper to mat my entities to DTOs and vise-versa, and also have a class with #ElementCollection relation.
the mapper seems to work fine for all other methods and it just output the entity as i want, however when it comes to delete mapping i get the following error printed along with a 500 http status. here's the error:
"ModelMapper mapping errors:\r\n\r\n1) Converter org.modelmapper.internal.converter.CollectionConverter#ddb7bc7 failed to convert java.util.List to java.util.List.\r\n\r\n1 error"
here is code:

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;

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

How to join Maps

How to join newMap detals in custMap.
Map<String, Customer> custMap= new HashMap<String,Customer>();
Map<String, DoCustomer> newMap= new HashMap<String,DoCustomer>();
for (Map.Entry<String, DoCustomer> cust: newMap.entrySet()) {
custMap.put(cust.getKey(),cust.getValue());
}
public class DoCustomer {
private Long id;
private String custName;
private String description;
private String status;
private List<DoCustomerBranch> doCustomerBranch=new ArrayList<DoCustomerBranch>
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;

return custName;
}
public void setCustName(String custName) {
this.custName = custName;

}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;

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
