guys i am making a grid library that uses hibernate and spring mvc to read data from db .. i have 2 table employee which has EPMID, EMPNAME, EMPAGE, SALARY, ADDRESS, department_id (refrences to department_id in department table ) and department which has department_id and name ... here is the Department.java
public class Department {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "department_id")
private int depId;
#Column(name = "name")
private String depName;
#OneToMany(mappedBy="department",cascade = { CascadeType.ALL }, orphanRemoval=true)
private List<Employee> employees;}
Employee.java
public class Employee {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "EMPID")
private int empId;
#Column(name = "EMPNAME")
private String empName;
#Column(name = "ADDRESS")
private String empAddress;
#Column(name = "SALARY")
private String salary;
#Column(name = "EMPAGE")
private int empAge;
#ManyToOne(cascade={CascadeType.ALL})
#JoinColumn(name="department_id")
private Department department;}
and the function that adds teh employee in service
public void addEmployee(String[] list, Employee employee) {
employee.getDepartment().setDepId(Integer.parseInt(list[3]));
employee.setEmpName(list[2]);
employee.setEmpAge(Integer.parseInt(list[4]));
employee.setEmpAddress(list[6]);
employee.setSalary(list[1]);
this.employeeDao.addOrEditEmployee(employee);
everything goes fine without that line employee.getDepartment().setDepId(Integer.parseInt(list[3])); but i want to add foreign key to reference on the primary one ..
here is the exception
SEVERE: Servlet.service() for servlet [sdnext] in context with path [/Spring3HibernateApp1] threw exception [Request processing failed; nested exception is java.lang.NullPointerException] with root cause

Do NOT maintain foreign keys using something like this
employee.getDepartment().setDepId(Integer.parseInt(list[3]));
Instead do
Department dept = departmentDao.findById(Integer.parseInt(list[3]));
employee.setDepartment(dept);
Hibernate will now create the database relationship between department and employee by inserting the department_id in the employee table.
P.S. I am assuming some class and method names as I do not have all of your code.
Regarding the NPE
I believe you received a null pointer exception because employee doesn't have a department at that point.
employee.getDepartment().setDepId(...

I have three tables, tables in sql servers , which Solved had been created by many-many relationship.
Solved table has a composite key, so i wrote a SolvedKey for its composite key SolvedKey
#Embeddable
public class SolvedKey implements Serializable {
#Column(name="userMailer")
private String usermail;
#Column(name="challengeID")
private int challengeid;
My Entity:
Solved: solved entity
#Entity
#Table(name = "Solved")
public class Solved {
#EmbeddedId
private SolvedKey solvedKey;
#ManyToOne(fetch = FetchType.LAZY)
#MapsId("usermail")
private User user;
#ManyToOne(fetch = FetchType.LAZY)
#MapsId("challengeid")
private Challenge chall;
#Temporal(TemporalType.DATE)
#DateTimeFormat(pattern="yyyy/mm/dd")
#Column(name = "dateSolved")
private Date dateSolved;
User: user entity
#Entity
#Table(name="Users")
public class User implements Serializable{
// declare field
#Id
#Column(name="Mail")
private String mail;
#Column(name="Username")
private String userName;
#Column(name="Password")
private String passWord;
#Column(name ="Validation")
private boolean valid;
#Column(name="Isadmin")
#Nullable
private boolean isAdmin;
#OneToMany(mappedBy = "user",cascade = CascadeType.ALL)
private List<Solved> challs = new ArrayList<Solved>();
Challenge: Challenge entity
#Entity
#Table(name="Challenges")
public class Challenge implements Serializable {
#Id
#GeneratedValue
#Column(name = "ID")
private int id;
#Column(name="challengName")
private String challengeName;
#Column(name = "score")
private int score;
#Column(name="fileAttach")
private String fileAttach;
#Column(name="description")
private String description;
#Column(name="hint")
private String hint;
#Column(name="major")
private String major;
#Column(name = "flag")
private String flag;
#OneToMany(mappedBy = "chall",cascade = CascadeType.ALL)
private List<Solved> users = new ArrayList<Solved>();
But i don't sure that it's correct. And when i try to request list of challenges of a user:
public void getListSolved(String mail){
User user = getUserByMail(mail);
System.out.println("User: " + user.getUserName());
System.out.println("Challs: " + user.getChalls());
user.getChalls().forEach(
(chall) -> System.out.println("Chall: "+ chall.getChall().getChallengeName()+ " | Date: " + chall.getDateSolved())
);
}
It failed because of the invalid column "user_Mail" , but i can't find where is that column in my code.

If you want reference column of User in Solved entity to be usermail, I suggest to design your entity as following. Main difference is that instead of having User and Challenge in Solved use it in SolvedKey as reference entity and don't forget to override equal and hashCode in SolvedKey.
SolvedKey Entity
#Embeddable
public class SolvedKey implements Serializable {
#ManyToOne(optional = false, fetch = FetchType.LAZY)
#JoinColumn(name = "usermail" , referencedColumnName = "Mail")
private User user;
#ManyToOne(optional = false, fetch = FetchType.LAZY)
private Challenge chall;
Soved Entity
#Entity
public class Solved {
#EmbeddedId
private SolvedKey solvedKey;
User -> to Solved relationship
#Entity
public class User {
#OneToMany(mappedBy = "solvedKey.user",cascade = CascadeType.ALL)
private List<Solved> challs = new ArrayList<Solved>();
Challenge -> to Solved relationship
#Entity
public class Challenge {
#OneToMany(mappedBy = "solvedKey.chall",cascade = CascadeType.ALL)
private List<Solved> users = new ArrayList<Solved>();
When I execute spring boot app , hibernate ddl is as following.
create table Solved (
dateSolved date,
chall_ID integer not null,
usermail varchar(255) not null,
primary key (chall_ID, usermail)
)
alter table Solved
add constraint FKx2kp7aliijq7g7xq0j4huqb4
foreign key (chall_ID)
references Challenge
alter table Solved
add constraint FKhycu95r961terhbackiixqwns
foreign key (usermail)
references User
I have 2 tables: Persons and Accounts(one to many relationship).
In my Person class I have:
#Entity
#Table(name="persons")
public class Person {
#Id
#Column(name="id")
#GeneratedValue(strategy=GenerationType.IDENTITY)
private int id;
private String name;
private String username;
private String password;
private String country;
private boolean admin;
#OneToMany(mappedBy="person")
#Cascade({CascadeType.ALL})
private Set<Account> accounts;
public Person(String name, String username, String password, String country, boolean admin) {
this.name = name;
this.username = username;
this.password = password;
this.country = country;
this.admin = admin;
}
public Person(){ }
//getters and setters
}
In my Account class I have:
#Entity
#Table(name="accounts")
public class Account {
#Id
#Column(name="accountId")
#GeneratedValue(strategy=GenerationType.IDENTITY)
private int accountId;
private int balance;
private String currency;
#ManyToOne
#JoinColumn(name="id")
private Person person;
public Account(int balance, String currency) {
this.balance = balance;
this.currency = currency;
}
private Account(){ }
//getters and setters
}
I'm using SQL server and the tables are created with the following code:
CREATE TABLE persons(
id int IDENTITY(1,1) PRIMARY KEY NOT NULL,
name nvarchar(30) NOT NULL,
username nvarchar(30) NOT NULL,
password nvarchar(30) NOT NULL,
country nvarchar(30) NOT NULL,
admin bit NOT NULL
);
CREATE TABLE accounts(
accountId int IDENTITY(10000,1) PRIMARY KEY NOT NULL,
balance int NOT NULL,
currency nvarchar(5) NOT NULL,
userId int NOT NULL foreign key references persons(id)
);
In my controller I'm saving a person and it works, then when trying to save 2 accounts of that person I get the following error: java.sql.SQLException: Invalid column name 'id'. The code:
Person person = new Person("Maurice","vvvvv","ccccc", "France", true);
this.personService.addPerson(person);
Account account1 = new Account(1000, "eur");
Account account2 = new Account(700, "gbp");
account1.setPerson(person);
account2.setPerson(person);
this.accountService.addAccount(account1);
this.accountService.addAccount(account2);
It's not the first time when I'm using a one-to-many relationship but I haven't encountered this error before.

#JoinColumn(name="id") should be #JoinColumn(name="userId")
Because userId is used as a foreign key in Accounts Table
It appears as if id column field for Person.java or Account.java is stored as Id in your database, while in your entity you have named it as id.
Can you please share the Person.java class and a full stacktrace of the error and please also check your database to make sure the fields are correct
Thanks.
I want to map JPA resultset to a custom POJO.
Below is the code
#SqlResultSetMapping(
name = "SearchVO",
entities = {
#EntityResult(
entityClass = UserInfo.class,
fields = {
#FieldResult(name = "profile_id", column = "id"),
#FieldResult(name = "first_name", column = "firstName"),
#FieldResult(name = "last_name", column = "lastName"),
#FieldResult(name = "email_id", column = "email")
}),
#EntityResult(
entityClass = ProjectVO.class,
fields = {
#FieldResult(name = "project_id", column = "id"),
#FieldResult(name = "project_title", column = "title")
}),
#EntityResult(
entityClass = DemoRealVO.class,
fields = {
#FieldResult(name = "demo_reel_id", column = "reelId"),
#FieldResult(name = "demo_reel_title", column = "title")
})
})
public class SearchVO {
private int profile_id;
private int project_id;
private int demo_reel_id;
private String first_name;
private String last_name;
private String email_id;
private String project_title;
private String demo_reel_title;
// getter and setter
}
Query query = entityManager.createNativeQuery(
"select u.id,u.first_name,u.last_name,p.id,p.title,d.reel_id,d.title from user_info u,projectvo p,demo_realvo d where (concat(u.first_name,' ',u.last_name,' ',p.title,' ',d.title) like lower(:queryString))", "SearchVO");
But it is giving me below error

Please tell me where i am going wrong.
With JPA 2.1, the #SqlResultSetMapping annotation should be placed on an entity class.
Getting java.sql.SQLException: Invalid column name even though column with same name are in table. what can be a reason?
I am trying to call sp with below code:
Session session = HibernateUtil.getSessionFactory().openSession();
Query query = session.getNamedQuery("EMPLOYEE.PRC_HB_EMP_SP1");
query.setParameter("IN_EMPID", empId);
List<Employee> empList = query.list();
System.out.println(empList);
Entity class Employee:
#Entity
#Table(name = "EMPLOYEE")
//#org.hibernate.annotations.NamedNativeQuery(name = "EMPLOYEE.PRC_HB_EMP_SP1", query = "call PRC_HB_EMP_SP1(?,:IN_EMPID)", callable = true, resultClass = Employee.class)
#org.hibernate.annotations.NamedNativeQuery(name = "EMPLOYEE.PRC_HB_EMP_SP1", query = "call PRC_HB_EMP_SP1(?,:IN_EMPID)", callable = true, resultClass = Employee.class)
public class Employee implements Serializable {
private static final long serialVersionUID = -723583058586873479L;
#Id
#Column(name = "EMPID")
private Integer empId;
#Column(name = "EMPNAME")
private String empName;
#Column(name = "ADDRESS")
private String empAddress;
#Column(name = "SALARY")
private Long salary;
#Column(name = "EMPAGE")
private Integer empAge;
............
}
here is sp:
create or replace PROCEDURE PRC_HB_EMP_SP1
(
Out_value OUT SYS_REFCURSOR,
IN_EMPID NUMBER
)
AS
BEGIN
open Out_value for
SELECT EMPID,EMPNAME
FROM EMPLOYEE
WHERE EMPID = IN_EMPID;
END PRC_HB_EMP_SP1;

Your mappings contain columns ADDRESS,SALARY and EMPAGE but those are missing from your SP.You need to include those in your statement.
I am writing an application where i am trying to make an example on hibernate search with Lucene.
In my database, i got an array named A_ROLE witch contains an ID field and a NAME field. Into this array i have store the data bellow:
1 - Agalloh
2 - Rorry Galaher
3 - Isis Isis
My entity class looks like this:
#Entity
#Table(name="A_ROLE")
#NamedQuery(name="ARole.findAll", query="SELECT a FROM ARole a")
#Indexed
public class ARole implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#DocumentId
#SequenceGenerator(name="A_ROLE_ID_GENERATOR", sequenceName="A_ROLE_SEQ")
#GeneratedValue(strategy=GenerationType.SEQUENCE, generator="A_ROLE_ID_GENERATOR")
#Column(unique=true, nullable=false, precision=38)
#Field(index=Index.YES, analyze=Analyze.YES, store=Store.NO)
//#NumericField
private long id;
#Column(length=50)
#Field(index=Index.YES, analyze=Analyze.YES, store=Store.NO)
private String name;
//bi-directional many-to-many association to APermission
#ManyToMany
#JoinTable(
name="A_ROLE_PERMISSION"
, joinColumns={
#JoinColumn(name="ROLE_ID", nullable=false)
}
, inverseJoinColumns={
#JoinColumn(name="PERMISSION_ID", nullable=false)
}
)
private List<APermission> APermissions;
//bi-directional many-to-many association to AUser
#ManyToMany(mappedBy="ARoles")
private List<AUser> AUsers;
constructor, getters and setters
and i have create an interface named DataBaseExchanges which contains a method lucinExample(). This method is responsible for the hibernate search and its implementation is being from the class bellow
import ec.ep.europarl.appdif.db.entity.ARole;
import ec.ep.europarl.appdif.service.DataBaseExchanges;
import java.util.List;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import org.hibernate.search.jpa.FullTextEntityManager;
import org.hibernate.search.query.dsl.QueryBuilder;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
#Service("dataSearch")
public class DataBaseExchangesImpl implements DataBaseExchanges {
#PersistenceContext
public EntityManager em;
#Override
#Transactional
public void lucinExample() {
FullTextEntityManager fullTextEntityManager =
org.hibernate.search.jpa.Search.getFullTextEntityManager(em);
//em.getTransaction().begin();
QueryBuilder qb =
fullTextEntityManager.getSearchFactory().buildQueryBuilder()
.forEntity(ARole.class).get();
org.apache.lucene.search.Query query = qb
.keyword()
.onFields("name")
.matching("agalloh")
.createQuery();
// wrap Lucene query in a javax.persistence.Query
org.hibernate.search.jpa.FullTextQuery persistenceQuery =
fullTextEntityManager.createFullTextQuery(query, ARole.class);
// execute search
List result = persistenceQuery.getResultList();
em.close();
}
}
i call this method from a controller, where i have #Autowird the above mentioned interface.
When i debug the above functionality it stops at this line of the implementation code:
org.hibernate.search.jpa.FullTextQuery persistenceQuery =
fullTextEntityManager.createFullTextQuery(query, ARole.class);
with error report:

I can't figure out what the problem is, at my maven dependencies i have include hibernate search 4.5.0.Final.
Please can anyone help on this?
Finally i got answer to my question, i realize that i haven't include this in pom file:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>4.3.4.Final</version>
</dependency>
