Here is my controller :
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import com.inconso.models.Inventory;
import com.inconso.models.Item;
import com.inconso.models.ItemInventory;
import com.inconso.repositories.InventoryRepository;
import com.inconso.repositories.ItemRepository;
#RestController
public class ItemController {
#Autowired
private ItemRepository itemRepos ;
#Autowired
private InventoryRepository inventoryRepos ;
#RequestMapping(value = "itemInventory/add/{company}", method = RequestMethod.POST)
public Object addItem(#RequestBody ItemInventory itemInventory) {
Item item = itemRepos.findOne(itemInventory.getItem().getId()) ;
// still add stuff here in case item not found
Inventory inventory = inventoryRepos.findOne(itemInventory.getInventory().getId()) ;
// still add stuff here if inventory not found
itemInventory.setInventory(inventory);
itemInventory.setItem(item);
item.getItemInventories().add(itemInventory) ;
inventory.getItemInventories().add(itemInventory) ;
System.out.println("-------"+itemInventory.getItem()+"---------");
itemRepos.save(item) ;
return "Item added" ;
}
}

I removed this line
item.getItemInventories().add(itemInventory) ;
and it worked, I think because inventory is the owner of the realtionship, so we should add the itemInventory object to inventory only not both (item and inventory)

}

If you want to check if the row exists, you can use "existsBy". This returns a boolean value which you could check in your if.
If you use "findOne" you get the row from the database (or null). If you do not need the data from the row, you better use exists. If you need it - store it in a variable and check if it's null.
Example with existsBy:
#EnableJpaRepositories
#Repository
public interface EmployeeRepo extends JpaRepository<Employee,Integer> {
boolean existsByEmailAndPassword(String email, String password);
}
EmployeeIMPL:
#Override
public String loginEmployee(LoginDTO loginDTO) {
if (employeeRepo.existsByEmailAndPassword(loginDTO.getEmail(), loginDTO.getPassword())) {
return "Login Success";
} else {
return "Login Fail";
}
}
Example with findBy:
#EnableJpaRepositories
#Repository
public interface EmployeeRepo extends JpaRepository<Employee,Integer> {
Employee findOneByEmailAndPassword(String email, String password);
}
EmployeeIMPL:
#Override
public String loginEmployee(LoginDTO loginDTO) {
Employee employee = employeeRepo.findOneByEmailAndPassword(loginDTO.getEmail(), loginDTO.getPassword());
if (employee != null) {
return "Login Success for " + employee;
} else {
return "Login Fail";
}
}
With findOne you could also use Optionals.
#EnableJpaRepositories
#Repository
public interface EmployeeRepo extends JpaRepository<Employee,Integer> {
Optional<Employee> findOneByEmailAndPassword(String email, String password);
}
EmployeeIMPL:
#Override
public String loginEmployee(LoginDTO loginDTO) {
Optional<Employee> employee = employeeRepo.findOneByEmailAndPassword(loginDTO.getEmail(), loginDTO.getPassword());
if (employee.isPresent()) {
return "Login Success for " + employee.get();
} else {
return "Login Fail";
}
}

As far as i can tell it needs an order to print them in a page which I already did in the query in the repo.

Please, note that you are importing java.awt.print.Pageable, java.awt.print.PageFormat and java.awt.print.Printable. That could be misleading, because the pagination with Spring Data uses org.springframework.data.domain.Pageable, so I'd change those imports.
Also, a better way to use pagination in the repository is to just pass the pagination configuration using a Pageable, like this:
#Repository
public interface BlogRepository extends JpaRepository<Blog, Long>{
#Query("SELECT b FROM Blog b LEFT JOIN FETCH b.user")
List<Blog> findBlogs(Pageable pageable);
}
This way, you can call the method from the service like this:
#Override
public List<Blog> findLatest5() {
return blogrepo.findBlogs(PageRequest.of(0, 5, Sort.by("date").descending())););
}

Save entity JPA with null id

I am trying to create a function for registering a user.
#Service
public class RegistrationService {
private AccountRepository accountRepository;
private UserRepository userRepository;
private final Logger logger = LogManager.getLogger(RegistrationService.class);
public Boolean createNewUser(Registration registration) {
User user = new User();
user.setUserName(registration.getUserName());
user.setPassword(registration.getPassword());
logger.info("attempting to create user: {}", user);
try {
userRepository.save(user);
} catch(Exception e) {
logger.error("Failed to register user: {}", e.getStackTrace());
return false;
}
Account account = new Account();
account.setUserId(user.getId());
account.setBillingAddress(registration.getBillingAddress());
account.setBillingCountry(registration.getBillingCountry());
account.setBillingProvince(registration.getBillingProvince());
account.setPhoneNumber(registration.getPhoneNumber());
account.setZip(registration.getZip());
logger.info("attempting to create account: {}", account);
try {
account = accountRepository.save(account);
} catch(Exception e) {
logger.error("Failed to register account: {}", e.getStackTrace());
return false;
}
return true;
}
}
I followed the advice from this post: Saving null as id, with hibernate, but the solution did not work for me.
Here is my user class
package com.company.app.model;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import lombok.Data;
#Entity
#Table(name="user")
#Data
public class User {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String userName;
private String password;
public Long getId() {
return this.id;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getUserName() {
return this.userName;
}
public void setPassword(String password) {
this.password = password;
}
public String getPassword() {
return this.password;
}
}
Here is my account class
package com.company.app.model;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import lombok.Data;
#Entity
#Table(name="account")
#Data
public class Account {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private Long userId;
private String billingAddress;
private String billingProvince;
private String billingCountry;
private String phoneNumber;
private String zip;
public Long getId() {
return this.id;
}
public void setUserId(Long userId) {
this.userId = userId;
}
public Long getUserId() {
return userId;
}
public String getBillingAddress() {
return billingAddress;
}
public void setBillingAddress(String billingAddress) {
this.billingAddress = billingAddress;
}
public String getBillingProvince() {
return billingProvince;
}
public void setBillingProvince(String billingProvince) {
this.billingProvince = billingProvince;
}
public String getBillingCountry() {
return billingCountry;
}
public void setBillingCountry(String billingCountry) {
this.billingCountry = billingCountry;
}
public String getPhoneNumber() {
return phoneNumber;
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
public String getZip() {
return zip;
}
public void setZip(String zip) {
this.zip = zip;
}
}
My log shows the following output
2021-04-14 14:40:09.265 INFO 15092 --- [nio-8080-exec-1] c.c.app.service.RegistrationService : attempting to create user: User(id=null, userName=evan, password=test123)

I guess you get this error because you didn't set id.
Try add user.setId(registration.getId());

At the End, the ID needs a value.
In your case the ID is annotated with #GeneratedValue(strategy = GenerationType.IDENTITY)
This means that you don't have to set the value for the ID in your Program.
But a value is still needed, therefore the DB has to take care of setting the ID.
In a mysql-table for example you can achieve this by defining the ID-Column as
`ID` bigint(20) NOT NULL AUTO_INCREMENT,

PersistentObjectException: Uninitialized proxy passed to persist

The code that is responsible for persisiting the policy is as follows:
public Subscriber addMemberToSteward(Long stewardId, Subscriber subscriber) {
Steward steward = this.findStewardById(stewardId);
if(steward == null){
throw new EcosureException(String.format("No steward found with id '%s'.",stewardId));
}
final BillingStatus billingStatus = BillingStatus.REG_IN_PROGRESS;
final MemberStatus memberStatus = MemberStatus.NEW;
final ProductPackage product = productService.findPackageById(subscriber.getProductPackageId());
subscriber.setNationalId(nationalIDNumberUtils.formatIdNumber(subscriber.getNationalId()));
final PolicyHolder policyHolder = convertToPolicyHolder(subscriber, product, billingStatus, memberStatus);
Policy policy = getPolicyFromSubscriberInfo(subscriber, policyHolder);
policy.setSteward(steward);
policy.setStatus(PolicyStatus.NEW);
System.out.println("Policy Holder" + policyHolder);
policyRepository.save(policy);
return subscriber;
}
The getPolicyFromSubscriberInfo method is below:
private Policy getPolicyFromSubscriberInfo(final Subscriber subscriberInfo, final PolicyHolder policyHolder) throws {
final Policy policy = new Policy();
policy.setMsisdn(subscriberInfo.getMsisdn());
policy.setPolicyNumber(policyNumberGenerator.getNextPolicyNumber());
policy.setPolicyName(policyHolder.getFirstname() + " " + policyHolder.getSurname());
policyHolder.setPolicy(policy);
CompositePolicyMemberPK policyMemberId = new CompositePolicyMemberPK();
policyMemberId.setPolicyNumber(policy.getPolicyNumber());
policyMemberId.setSuffixNumber(policyNumberGenerator.getNextSuffix(policy.getPolicyNumber(),true));
policyHolder.setPolicyMemberId(policyMemberId);
policy.setPolicyHolder(policyHolder);
return policy;
}
The PolicyRepository is shown below:
public interface PolicyRepository extends JpaRepository<Policy, String> {
}
When I try to persist a Policy entity I am getting the error below:

Can anyone please assist me in identifying where I am going wrong.

Could not execute JDBC batch update;

hi i am running spring with jpa application while i am inserting the data into data i am getting the above exception in my entity class i make the userid as generator value and in my database table column i given the userid as first column but while executing the query it is showing the userid column as last column can any one tell me why it is happening like this and why i am getting this exception.
here is my entity class
#Entity
#Table(name="user",schema="schm_mail")
public class UserEntity {
#Id
#SequenceGenerator(name = "generator", sequenceName = "schm_mail.userlogin_sequence", allocationSize=1)

#Column(name="userid")
private int userId;
#Column(name="firstname")
private String firstName;
#Column(name="lastname")
private String lastName;
#Column(name="mailid")
private String mailId;
#Column(name="phonenumber")
private String phoneNumber;
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}

return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}

this.mailId = mailId;
}
public String getPhoneNumber() {
return phoneNumber;
}

}
here is my exception stack trace
