Not able to retrive data from Crud Operation in Hibernate

I have a application written in Spring, Hibernate and SpringBoot,
I have 2 entities class with one to many mapping,
Here are my LeadUserDb entity class
#Entity
#Table(name="lead_user_db")
#NamedQuery(name="LeadUserDb.findAll", query="SELECT l FROM LeadUserDb l")
public class LeadUserDb implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
#Column(name="branchcode")
private String branchcode;
#Column(name="reporting_level")
private int reportingLevel;
//bi-directional many-to-one association to UserBasicDetailsDb
#ManyToOne
#JoinColumn(name="email_Id")
private UserBasicDetailsDb userBasicDetailsDb;
public LeadUserDb() {
}
public String getBranchcode() {
return this.branchcode;
}
public void setBranchcode(String branchcode) {
this.branchcode = branchcode;
}
public int getReportingLevel() {
return this.reportingLevel;
}
public void setReportingLevel(int reportingLevel) {
this.reportingLevel = reportingLevel;
}
public UserBasicDetailsDb getUserBasicDetailsDb() {
return this.userBasicDetailsDb;
}
public void setUserBasicDetailsDb(UserBasicDetailsDb userBasicDetailsDb) {
this.userBasicDetailsDb = userBasicDetailsDb;
}
And This is my UserBasicDetailsDb Entity Class
#Entity
#Table(name="user_basic_details_db")
public class UserBasicDetailsDb implements Serializable {
private static final long serialVersionUID = 1L;
#Id
private String email;
private String address;
private String city;
private String dob;
private String mobile;
private String name;
private String pan;
private String pincode;
private String state;
#OneToMany(mappedBy="userBasicDetailsDb")
private List<LeadUserDb> leadUserDbs;
public UserBasicDetailsDb() {
}
public String getEmail() {
return this.email;
}
public void setEmail(String email) {
this.email = email;
}
public String getAddress() {
return this.address;
}
public void setAddress(String address) {
this.address = address;
}
public String getCity() {
return this.city;
}
public void setCity(String city) {
this.city = city;
}
public String getDob() {
return this.dob;
}
public void setDob(String dob) {
this.dob = dob;
}
public String getMobile() {
return this.mobile;
}
public void setMobile(String mobile) {
this.mobile = mobile;
}
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
public String getPan() {
return this.pan;
}
public void setPan(String pan) {
this.pan = pan;
}
public String getPincode() {
return this.pincode;
}
public void setPincode(String pincode) {
this.pincode = pincode;
}
public String getState() {
return this.state;
}
public void setState(String state) {
this.state = state;
}
public List<LeadUserDb> getLeadUserDbs() {
return this.leadUserDbs;
}
public void setLeadUserDbs(List<LeadUserDb> leadUserDbs) {
this.leadUserDbs = leadUserDbs;
}
public LeadUserDb addLeadUserDb(LeadUserDb leadUserDb) {
getLeadUserDbs().add(leadUserDb);
leadUserDb.setUserBasicDetailsDb(this);
return leadUserDb;
}
public LeadUserDb removeLeadUserDb(LeadUserDb leadUserDb) {
getLeadUserDbs().remove(leadUserDb);
leadUserDb.setUserBasicDetailsDb(null);
return leadUserDb;
}
what i want to achieve is to create a query like this one
SELECT a.branchcode as branchCode,b.name FROM lead_user_db a
inner join user_basic_details_db b
where b.email = a.email_id and a.reporting_level = 3
here is what I have written my Repository class
public interface GetUserList extends CrudRepository<LeadUserDb, Integer> {
#Query(value = "SELECT a.id, a.branchcode as branchCode,b.name as name,a.reporting_level,a.email_id FROM lead_user_db a\n" +
"inner join user_basic_details_db b\n" +
"where b.email = a.email_id and a.reporting_level = ?1", nativeQuery = true)
List<LeadUserDb> findByReportingLevel(int reportingLevel);
}
and this is how I am calling it
UserBasicDetailsDb details = GetUserList.findByReportingLevel(3);
NOTE
Getting a new error Cannot determine value type from string test#dev.com
I am getting a hell lot of data, and the actual output have only 2 records
My question is how can i fetch the list of user based on reportingLevel
Any help would be appreciated

How to join multiple tables without relationship

This is my 1st project in Java/Hibernate.
I m trying to join two tables but even after searching a lot, I couldn't find the proper solution to achieve what i want.
Let me explain you what i have currently.
I have two entities:
#Entity
#Table(name = "admin")
public class AdminLogin {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private String firstName;
private String lastName;
private String username;
private String password;
private String status;
private String userRole;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public String getUserRole() {
return userRole;
}
public void setUserRole(String userRole) {
this.userRole = userRole;
}
}
#Entity
#Table(name = "user_balance_log")
public class UserBalanceLog {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private int userId;
private int adminId;
private Float balance;
private String balanceType;
private String message;
#Temporal(javax.persistence.TemporalType.DATE)
private Date dateCreated;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
public int getAdminId() {
return adminId;
}
public void setAdminId(int adminId) {
this.adminId = adminId;
}
public Float getBalance() {
return balance;
}
public void setBalance(Float balance) {
this.balance = balance;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public Date getDateCreated() {
return dateCreated;
}
public void setDateCreated(Date dateCreated) {
this.dateCreated = dateCreated;
}
public String getBalanceType() {
return balanceType;
}
public void setBalanceType(String balanceType) {
this.balanceType = balanceType;
}
}
I want to join the adminId from User Balance Log Entity to Admin Login Entity.
This is what i have currently.
Session session = this.sessionFactory.getCurrentSession();
Criteria criteria = session.createCriteria(UserBalanceLog.class, "ubl");
criteria.setProjection(Projections.projectionList().add(Projections.property("balance"),"balance").add(Projections.property("balanceType"),"balanceType").add(Projections.property("message"),"message").add(Projections.property("dateCreated"),"dateCreated"));
criteria.addOrder(Order.desc("id"));
if (parameters.get("userId") != null) {
criteria.add(Restrictions.eq("userId", new Integer(parameters.get("userId"))));
}
if (parameters.get("balanceType") != null) {
criteria.add(Restrictions.eq("balanceType", parameters.get("balanceType")));
}
if (parameters.get("dateCreated") != null) {
criteria.add(Restrictions.eq("dateCreated", parameters.get("dateCreated")));
}
List userBalanceList = criteria.list();
Please guide me.
Thanks

Finally i figured it out myself of course with the help/guidance of #vc73.
This is the updation i had to do in model:
#Entity
#Table(name = "user_balance_log")
public class UserBalanceLog {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private int userId;
#ManyToOne
#JoinColumn(name="adminId")
private AdminLogin adminId;
private Float balance;
private String balanceType;
private String message;
#Temporal(javax.persistence.TemporalType.DATE)
private Date dateCreated;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
public AdminLogin getAdminId() {
return adminId;
}
public void setAdminId(AdminLogin adminId) {
this.adminId = adminId;
}
public Float getBalance() {
return balance;
}
public void setBalance(Float balance) {
this.balance = balance;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public Date getDateCreated() {
return dateCreated;
}
public void setDateCreated(Date dateCreated) {
this.dateCreated = dateCreated;
}
public String getBalanceType() {
return balanceType;
}
public void setBalanceType(String balanceType) {
this.balanceType = balanceType;
}
}
and in the DAO:
Session session = this.sessionFactory.getCurrentSession();
Criteria criteria = session.createCriteria(UserBalanceLog.class, "ubl");
criteria.createAlias("ubl.adminId", "a");
criteria.setProjection(Projections.projectionList().add(Projections.property("balance").as("balance")).add(Projections.property("balanceType").as("balanceType")).add(Projections.property("message").as("message")).add(Projections.property("dateCreated").as("dateCreated")).add(Projections.property("a.username").as("username")));
criteria.addOrder(Order.desc("id"));
if (parameters.get("userId") != null) {
criteria.add(Restrictions.eq("userId", new Integer(parameters.get("userId"))));
}
if (parameters.get("balanceType") != null) {
criteria.add(Restrictions.eq("balanceType", parameters.get("balanceType")));
}
if (parameters.get("dateCreated") != null) {
criteria.add(Restrictions.eq("dateCreated", parameters.get("dateCreated")));
}
criteria.setResultTransformer(Criteria.ALIAS_TO_ENTITY_MAP);
criteria.setFirstResult(start);
criteria.setMaxResults(Pagination.limitPerPage);
List userBalanceList = criteria.list();
I hope it will help someone else.

How to populate foreign key in table Spring + Hibernate + Spring Security

I want make a case, when user is authenticated by Spring Security and then he fill adres form I would like to automatically updated a foreign key column "adres_id" in user table. Please give me a tip how implement this in the most popular way
I how somethig like this
Address Table:
User Table:
Adres

User unidirectional relation between User and Address if Address object does not supposed to know about its owner (generally it does not). I would prefer user id in Address table if a User have more than one Address (one-to-many relation).
But for your question you may design like that,
public class User{
...
#OneToOne(CascadeType.REMOVE)//this is for to remove address when user is removed
#JoinColumn(name="HOME_ADDRESS_ID")
private Address address;
...
}
and
public class Address {
#Id
#GeneratedValue(strategy = GenerationType.AUTO )
int id;
#Column(name="country", nullable=false)
private String country;
private String street;
private String postcode;
private String telephone;
private String pesel;
//no user object here
public int getId() {
return id;
}
...
}

OneToMany relationship doesn't save foreign key

I am doing a OneToMany relationship in a hibernate query. It's working fine but the donorId is not going to the blood table.

try{
Blood blood = new Blood();
Donor donor = new Donor();
blood = (Blood)bloodDonor.getBlood();
donor = (Donor)bloodDonor.getDonor();
sessionFactory = new Configuration().configure().buildSessionFactory();

session.beginTransaction();
session.save(donor);
session.save(blood);
session.getTransaction().commit();

Blood Resource:
#Path("blood")
public class BloodResource {

#Path("new")
#POST
#Produces(MediaType.APPLICATION_JSON)
#Consumes(MediaType.APPLICATION_JSON)
public BloodDonor addNewDonor(BloodDonor blood){
return bloodService.addNewBlood(blood);
}
}
Console:
Hibernate: select nextval ('hibernate_sequence')
Hibernate: select nextval ('hibernate_sequence')
Hibernate: insert into DONOR (age, city, cnic, contactNumber, country, email, firstName, homeNumber, houseNo, lastName, streetNo, town, donorId) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
Hibernate: insert into BLOOD (bloodType, donor_id, price, bloodId) values (?, ?, ?, ?)

First:
Add CascadeType:
#OneToMany(cascade = CascadeType.ALL, mappedBy="donor")
private Set<Blood> blood;
Second:
Your Entities should be interconnected e.g. Donor's Set<Blood> should contain a link to Blood and Blood's field Donor should be set to that Donor instance.
So, lets try to interconnect them:
Session session = sessionFactory.openSession();
session.beginTransaction();
Donor donor = new Donor();
Blood blood = new Blood();
blood.setDonor(donor);
HashSet<Blood> bloods = new HashSet<Blood>();
bloods.add(blood);
donor.setBlood(bloods);
//set some another fields if you want or they are NOT NULL in database
session.save(donor); //blood should be saved automatically due to cascade
session.getTransaction().commit();
session.close();
This should work if everything is alright with your database structure.
