Update DB column which has null value in Spring boot JPA

Update DB column which has null value in Spring boot JPA - java

I am trying to update in the database with the help of the Spring JPA and having an issue while doing it. I have an Embedded class in my entity. My entity class is :
#Entity
#Data
public class Users extends AbstractEntity {
private String name;
private String email;
private Audit audit;
private TransferDetails transferDetails;
private BeneficiaryDetails beneficiaryDetails;
}
My Repository class is :
public interface UserRepo extends JpaRepository<Users, Long> {
}
Audit, Transfer and Beneficiary Details are my Emededded class and those are :
#Embeddable
#Data
public class Audit {
private String createdBy;
private Date createdDate;
}
#Data
#Embeddable
public class BeneficiaryDetails {
private String BeneficiaryName;
public String getBeneficiaryName() {
return BeneficiaryName;
}
public void setBeneficiaryName(String beneficiaryName) {
BeneficiaryName = beneficiaryName;
}
}
#Data
#Embeddable
public class TransferDetails {
#Column(name = "TransferCurrency")
private String TransferCurrency;
private String ChequeCurrency;
}
My Controller class is:
#RestController
#RequestMapping("/api/v1/Users")
public class UserController {
private static final Logger LOGGER = LoggerFactory.getLogger(UserController.class);
#Autowired
private UserRepo userRepo;
#GetMapping("/users/{id}")
public ResponseEntity<Users> getTutorialById(#PathVariable("id") long id) {
Optional<Users> userData = userRepo.findById(id);
if (userData.isPresent()) {
return new ResponseEntity<>(userData.get(), HttpStatus.OK);
} else {
return new ResponseEntity<>(HttpStatus.NOT_FOUND);
}
}
#PostMapping(path = "/saveData", produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Users> createTutorial(#RequestBody Users users) {
try {
LOGGER.info("Starting to save the form.....");
return new ResponseEntity<>(userRepo.save(users), HttpStatus.CREATED);
} catch (Exception e) {
return new ResponseEntity<>(HttpStatus.INTERNAL_SERVER_ERROR);
}
}
#Transactional
#PutMapping("/updateData/{id}")
public ResponseEntity<Users> updateTutorial(#PathVariable("id") long id, #RequestBody Users users) {
try {
Optional<Users> userRepoById = userRepo.findById(id);
LOGGER.info("Starting to update the form.....");
if (userRepoById.isPresent()) {
Users _users = userRepoById.get();
_users.setName(users.getName());
_users.setEmail(users.getEmail());
_users.setAudit(users.getAudit());
LOGGER.info("getTransferCurrency --> " + users.getTransferDetails().getTransferCurrency());
LOGGER.info("getChequeCurrency --> " + users.getTransferDetails().getChequeCurrency());
**_users.getTransferDetails().setTransferCurrency(users.getTransferDetails().getTransferCurrency());**
LOGGER.info("getBeneficiaryName --> " + users.getBeneficiaryDetails().getBeneficiaryName());
_users.getBeneficiaryDetails().setBeneficiaryName(users.getBeneficiaryDetails().getBeneficiaryName());
return new ResponseEntity<>(userRepo.save(_users), HttpStatus.OK);
} else {
return new ResponseEntity<>(HttpStatus.NOT_FOUND);
}
} catch (Exception e) {
LOGGER.error(e.getMessage());
String str = "";
for (int i = 0; i < (e.getStackTrace().length); i++)
str = str + e.getStackTrace()[i] + " <br> ";
System.out.println("EXP MSG: " + str);
return new ResponseEntity<>(HttpStatus.INTERNAL_SERVER_ERROR);
}
}
}
My error stack trace is :

What I understand is that I have some null values in the columns of DB and I am trying to update them. Is there something I am missing? Could someone me help in this regard? Any help will be much appreciated. Thanks

Have you tried this?
TransferDetails td = users.getTransferDetails();
if(td != null) {
TransferDetails _td = _users.getTransferDetails();
if(_td != null) {
_td.setTransferCurrency(td.getTransferCurrency());
} else {
_td = new TransferDetails();
_td.setTransferCurrency(td.getTransferCurrency());
_users.setTransferDetails(_td);
}
}

By reading the code, I see _users.getTransferDetails(). is null. Because, the logger above didn't throw null pointer exception where you're printing users.getTransferDetails().
Set value of TransferDetails only when it is not null like:
// You need to check if the
// `_user.getTransferDetails` is not null,
// then only you can call `setTransferCurrency` of that object.
// Otherwise you'll end up with a NullPointerException.
if(_users.getTransferDetails() !=null)
_users.getTransferDetails().setTransferCurrency(users.getTransferDetails().getTransferCurrency());

I am getting an Status 500 Internal Error from my backend with Spring Boot

So I am testing my employee manager app in postman, and my delete get and all of the other requests work, but my update(put) request doesn't. I have also made the front end in Angular that is connected to the BE, but I think the Angular part isn't making the problem, if someone thinks that it is, please let me know I will gladly post that code also.
I am not sure how to fix this error, this is the code:

2022-08-21 02:01:02.830 WARN 7332 --- [l-1 housekeeper] com.zaxxer.hikari.pool.HikariPool : HikariPool-1 - Thread starvation or clock leap detected (housekeeper delta=44m1s400ms600µs500ns).
Example of my JSON that I put
{ "id": 17, "email": "cjufi#gmail.com", "imageUrl": "bootdey.com/img/Content/avatar/avatar1.png", "jobTitle": "Java", "name": "cjufi", "phoneNumber": "555333" }

The JSON payload what you are using to update your entity :
{ "id": 17, "email": "cjufi#gmail.com", "imageUrl": "bootdey.com/img/Content/avatar/avatar1.png", "jobTitle": "Java", "name": "cjufi", "phoneNumber": "555333" }
Does not contain employeeCode. So it's like you are passing NULL value but in your DB you said it should be non-null. That's why you are getting error.
You can either remove the constraints for the employeeCode column or provide the actual value when updating

If I'm reading you correctly, you don't want employeeCode to be updatable, as defined by your Entity with #Column(nullable = false, updatable = false).
The other answers are wrong, you don't have to add that field to your JSON when you're only updating. But this fails on your PUT request as you don't attempt to find the existing Employee first, but simply try to update with an entirely new object (which does have that null field that shouldn't be nullable by then) and are re-using your Entity as an input object for your Controller.
The usual way to do this would be to create a DTO specifically for this, then try to find the existing database entity based on the id and update that.
Another problem with your current approach is that there's nothing stopping someone from just passing an entirely new Employee with a new id to that update endpoint, and creating their own id that way.
You could also require that id to be in the request path so you don't have a PUT request on the main endpoint or a separate /update path, but rather have a structure like /employees/{id} where you can then parse the path and first attempt to find that employee with the parsed id.
Small example:
#PutMapping(value = "/{id}", consumes = APPLICATION_JSON_VALUE)
public ResponseEntity<EmployeeOutputDTO> updateEmployee(
#PathVariable("id") UUID id,
#RequestBody #Valid EmployeeInputDTO employeeDTO) {
EmployeeOutputDTO responseDTO = employeeService.apiUpdate(id, employeeDTO);
return ResponseEntity.ok(responseDTO);
}
public EmployeeOutputDTO apiUpdate(UUID id, EmployeeInputDTO employeeDTO) {
log.info("Updating employee");
Employee existingEmployee = findOrThrowNotFoundException(id);
// ...do update
}

you give the employeeCode a null, but it was defined not null in database

Unable to get data from h2

I'm trying to do a simple task. I've an API which is trying to create a post using userId and post desc as params. I'm initializing users in h2 DB directly using data.sql. In PostService, I'm trying to get user by userId using userRepo.findById(userId). The param is passed to the service from the request. However, I'm not getting any users. I'm getting a NullPointerException. I checked the h2 db and I can see my users being present. Even the sout's are not working.
Tried a few answers from internet, no luck as of yet.
Here's the code:

Got it!
A silly mistake but I'm a noob to spring boot. In the #RequestBody class, I'd named the int param differently as to what I was sending in the request. My question then is, in spring do we have to have same names in request and in the class variables?

Why do you declare your path variable there and you don't use it ?
#GetMapping("/getAllByUser")
public List<Post> getAllPostsByUser(#PathVariable Integer user) {
return postService.getAllPostsByUser(user);
}
Instead you should pass the user id in the URL of the post request:
#GetMapping("/getAllByUser/{user})
public List<Post> getAllPostsByUser(#PathVariable("user") Integer user) {
return postService.getAllPostsByUser(user);
}
Of course it will trow a NullPointerException because you are calling the API with a null user.

Can not set int field ch.bbw.apimashup.entity.Request.id to ch.bbw.apimashup.entity.Request

When I try to create a new entry for my DB I get the error which says that the application is trying to set the int field to the Request object, but I do not see how this is possible? What could be a possible reasoning behind this? The getters and setters are correctly written and the datatypes correspond with the DB data types.
Request entity class:
package ch.bbw.apimashup.entity;
import javax.persistence.*;
#Entity
#NamedQuery(name="Request.findAll", query="SELECT r FROM Request r")
#Table(name="requests")
public class Request {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "ID", unique = true)
private int id;
#Column(name = "request")
private String request;
public Request(int id, String request) {
this.id = id;
this.request = request;
}
public Request(String request) {
this.request = request;
}
public Request() {
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getRequest() {
return request;
}
public void setRequest(String request) {
this.request = request;
}
}
Full error message which is displayed to me:

SpringBoot:How can I bind two JSON pojo into two seperate objects using Wrapper Class and save them to my DB?

I have used Wrapper Class to keep both the Objects in JSON but when I am trying to fetch it using #RequestBody in my Controller I am getting a NullPointerException. I think the code structure will make more sense in understanding.
Model - SupMain.java
private Supplier supplier;
private Supplier_Part supplierPart;
public SupMain(Supplier supplier, Supplier_Part supplierPart) {
this.supplier = supplier;
this.supplierPart = supplierPart;
}
public Supplier getSupplier() {
return supplier;
}
public Supplier_Part getSupplierPart() {
return supplierPart;
}
}
Supplier.java
#Table
public class Supplier {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long sup_Id;
private String sup_name;
private String sup_mailId;
private int sup_phoneNo;
private String sup_location;
private String sup_feedback;
public Supplier_Part getSupplier_part() {
return supplier_part;
}
public void setSupplier_part(Supplier_Part supplier_part) {
this.supplier_part = supplier_part;
}
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "part_Id",nullable=false,unique=true)
private Supplier_Part supplier_part;
public Supplier() { }
public Supplier(Long sup_Id, String sup_name, String sup_mailId, int sup_phoneNo, String sup_location, String sup_feedback) {
this.sup_Id = sup_Id;
this.sup_name = sup_name;
this.sup_mailId = sup_mailId;
this.sup_phoneNo = sup_phoneNo;
this.sup_location = sup_location;
this.sup_feedback = sup_feedback;
}

return sup_Id;
}
public void setSup_Id(Long sup_Id) {
this.sup_Id = sup_Id;
}
public String getSup_name() {
return sup_name;
}
public void setSup_name(String sup_name) {
this.sup_name = sup_name;
}
public String getSup_mailId() {
return sup_mailId;
}
public void setSup_mailId(String sup_mailId) {
this.sup_mailId = sup_mailId;
}

return sup_phoneNo;
}
public void setSup_phoneNo(int sup_phoneNo) {
this.sup_phoneNo = sup_phoneNo;
}
public String getSup_location() {
return sup_location;
}
public void setSup_location(String sup_location) {
this.sup_location = sup_location;
}
public String getSup_feedback() {
return sup_feedback;
}
public void setSup_feedback(String sup_feedback) {
this.sup_feedback = sup_feedback;
}
#Override
public String toString() {
return "Supplier{" +
"sup_Id=" + sup_Id +
", sup_name='" + sup_name + '\'' +
", sup_mailId='" + sup_mailId + '\'' +
", sup_phoneNo=" + sup_phoneNo +
", sup_location='" + sup_location + '\'' +
", sup_feedback='" + sup_feedback + '\'' +
'}';
}
}
Similarly I have another Supplier_Part entity also.
I have two repositories that are extending CRUD and a Controller where I am trying to keep a rest end point of POST where I want to take two objects from JSON and store them to my DB.
SupplierController.java
#Controller
public class SuppliersController {
#Autowired
SupplierService supplierService;
#Autowired
Supplier_PartRepoistory supplier_partRepoistory;
#Autowired
SupplierRepository supplierRepository;
#RequestMapping("/suppliers/{id}")
public List<Supplier> getAllSuppliers(#Param("id") Long id){
return supplierService.getSupliersByPart(id);
}
#RequestMapping("/addSuppliers",method = RequestMethod.POST)
public Supplier addSupplier(#RequestBody SupMain supMain){
Supplier supplier=supMain.getSupplier();
System.out.println(supplier);
Supplier_Part supplierPart=supMain.getSupplierPart();
List<Supplier> list=new ArrayList<>();
list.add(supplier);
supplierPart.setSupplierList(list);
supplier.setSupplier_part(supplierPart);
supplierRepository.save(supplier);
supplier_partRepoistory.save(supplierPart);
return supplier;
}
}
This is how my JSON data looks like
{
"Supplier":{
"sup_Id":1,
"sup_name":"Arpita",
"sup_mailId":"arpitamitra",
"sup_phoneNo":"98856565",
"sup_location":"bakers street",
"sup_feedback":"Best"
},
"Supplier_Part":{
"part_Id":1,
"part_name":"Monitor",
"part_desc":"xyzzz",
"part_quantity":20,
"part_timePeriod":5
}
}
Getting a 500 internal server error with

Thanks a Ton in advance !

It's the keys "Supplier" and "Supplier_Part" of the input which is not letting the data gets bound to your SupMain class property "supplier" and supplier_part".
It should be of the same case as the class property.
Rename it and try, I believe it should work.

The JSON data needs to be updated !
{
"supplier":{
"sup_Id":1,
"sup_name":"Arpita",
"sup_mailId":"arpitamitra",
"sup_phoneNo":"98856565",
"sup_location":"bakers street",
"sup_feedback":"Best"
},
"supplierPart":{
"part_Id":1,
"part_name":"Monitor",
"part_desc":"xyzzz",
"part_quantity":20,
"part_timePeriod":5
}
}
instead of Supplier and Supplier_Part !
SupMain class has two private variables name supplier and supplierPart
Thanks !
