ConstraintValidator is not working (how can I do it?)

I will try to explain it as simple as I can. I have one entity class, one service, one repository.
User.class
#NotNull
#NotEmpty
#UniqueEmail
private String email;
UserRepo
public interface UserRepository extends JpaRepository<User,Long> {
boolean findByEmail(String email);
}
UserService
#Service
public class UserService {
private final UserRepository userRepository;
PasswordEncoder passwordEncoder;
public UserService(UserRepository userRepository) {
this.userRepository = userRepository;
this.passwordEncoder = new BCryptPasswordEncoder();
}
public UserResponseDTO createUser(UserRequestDTO userRequestDTO){
userRequestDTO.setPassword(passwordEncoder.encode(userRequestDTO.getPassword()));
User u = userRepository.save(UserMapper.INSTANCE.entityToDto(userRequestDTO));
return UserMapper.INSTANCE.toEntity(u);
}
public boolean findUserByUserName(String email){
if(userRepository.findByUsername(email)){
return true;
}
return false;
}
public boolean findUserByUserEmail(String email){
if(userRepository.findByEmail(email)){
return true;
}
return false;
}
}
UserController
#CrossOrigin
#RestController
public class UserController {
private final String endPointName = "api";
#Autowired
private UserService userService;
#ResponseStatus(HttpStatus.CREATED)
#PostMapping(path = endPointName+"/addUser", consumes = "application/json")
public GenericResponseMessage addUser(#Valid #RequestBody UserRequestDTO userRequestDTO){
userService.createUser(userRequestDTO);
return new GenericResponseMessage("ok");
}
}
Validator Annotation
#Constraint(validatedBy = UniqueEmailValidator.class)
#Retention(RetentionPolicy.RUNTIME)
#Target({ ElementType.FIELD })
public #interface UniqueEmail {
public String message() default "There is already user with this email!";
public Class<?>[] groups() default {};
public Class<? extends Payload>[] payload() default{};
}
UniqueEmailValidator class
#Component
public class UniqueEmailValidator implements ConstraintValidator<UniqueEmail, String> {
#Autowired
private UserService userService;
#Override
public boolean isValid(String value, ConstraintValidatorContext context) {
return value != null && !userService.findUserByUserEmail(value);
}
}

I added #Component annotation but it did not work.
I edit and try #Valid annotation #Valited but it did not work.
I add
"spring.jpa.properties.javax.persistence.validation.mode = none"
in application.properties file. If I add this, the error goes away but the "validation" in the whole system is disabled.
If I remove
"spring.jpa.properties.javax.persistence.validation.mode = none"
all validations like #NotNull, #NotEmpty, #Pattern etc are working except the annotation I created.
But if I add
"spring.jpa.properties.javax.persistence.validation.mode = none"
all of them are disabled, and the data is entered into the database without any checks.

It seems that the autowiring of your UserService does not work correctly which leads to a NPE when the validator tries to call the findUserByUserEmail on your UserService. Try the following validator:
#Documented
#Target(FIELD)
#Retention(RUNTIME)
#Constraint(validatedBy = UniqueEmail.Validator.class)
public #interface UniqueEmail {
String message() default "There is already a user with this email!";
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
class Validator implements ConstraintValidator<UniqueEmail, String> {
#Autowired
private UserService userService;
#Override
public void initialize(UniqueEmail constraintAnnotation) {}
#Override
public boolean isValid(String email, ConstraintValidatorContext context) {
return value != null && !userService.findUserByUserEmail(value);
}
}
}
Make sure to define a LocalValidatorFactoryBean as well:
#Configuration
public class ValidationConfiguration {
#Bean
#Primary
LocalValidatorFactoryBean localValidatorFactoryBean() {
return new LocalValidatorFactoryBean();
}
}
For me, this apporach worked at several places.
By the way, I strongly recommend using exists queries instead of find queries and then checking if the object is not null. With your way, you load the whole entity from the database just to check if it is present. It is much more performant if you let your JPA provider execute a SQL exists query instead. You can write exists queries in your repository as follows:
public interface UserRepository extends JpaRepository<User,Long> {
boolean existsByEmail(String email);
boolean existsByUsername(String email);
}
For more information check the Spring Reference or this Baeldung article.

I created an example project based on your code fragments in your original post.
But I slightly changed the implementation of ConstraintValidator.
#RequiredArgsConstructor
class UniqueEmailValidator implements ConstraintValidator<UniqueEmail, String> {
private final UserAccountRepository userAccounts;
#Override
public void initialize(UniqueEmail constraintAnnotation) {
}
#Override
public boolean isValid(String value, ConstraintValidatorContext context) {
if (StringUtils.hasText(value)) {
return !userAccounts.existsByEmail(value);
}
// empty or blank text, skip to use #NotBlank #NotEmpty to validate it.
return true;
}
}
And I added a simple test to verify it.
#Test
public void testSaveUserAccount() throws Exception {
when(userAccounts.existsByEmail(anyString())).thenReturn(true);
var body = objectMapper.writeValueAsBytes(new CreateUserAccountCommand("foo#bar.com", "test"));
mockMvc.perform(post("/users").contentType(MediaType.APPLICATION_JSON).content(body))
.andExpect(status().isBadRequest());
verify(userAccounts, atLeastOnce()).existsByEmail(anyString());
verifyNoMoreInteractions(userAccounts);
}
Run the tests in IDE, you can the constraints violations in the console like this.
[Field error in object 'createUserAccountCommand' on field 'email':
rejected value [foo#bar.com];
codes [UniqueEmail.createUserAccountCommand.email,UniqueEmail.email,UniqueEmail.java.lang.String,UniqueEmail];
arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [createUserAccountCommand.email,email];
arguments []; default message [email]];
default message [There is already user with this email!]] ]
Check my example project from my Github.

Solution for my side
ı have user entity class I removed all validation annotations from the pure entity class.
#Entity
#Getter
#Setter
#Table(name = "users")
#NoArgsConstructor
#AllArgsConstructor
public class User {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long userid;
private String username;
private String userDisplayName;
private String email;
private String password;
}
UserDTO -> I put all the properties related to validation in the DTO class and requested the DTO data from the client in the controller layer.
#Getter
#Setter
public class UserRequestDTO implements Serializable {
#NotNull
#NotEmpty
#Size(min = 2,max = 20)
private String username;
#NotNull
#NotEmpty

Trying and failing to create a DTO in Spring-boot DTO that grabs data from 3 tables

I'm coding an API that connects an online db to an android app and have gotten stuck on how to create a DTO that takes data from 3 tables that are connected with each other.
It's the first API I'm coding and I'm still trying to learn good practices so any suggestions are welcome.
I've reached the point where I really don't know where else to look for an answer, since all the answers I find are explaining how to use a query to take data from a single table(might be searching for it using the wrong terminology since I'm not a native English speaker)
These are the entities I create in the API:
Employees
#Entity
#Table(name = "employees")
public class Employees {
#Id
#Column(name = "eid")
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int eid;
#Column(name = "first_name")
private String first_name;
#Column(name = "last_name")
private String last_name;
#Column(name = "birth_date")
#JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd")
private Date birth_date;
#Column(name = "jid")
private int jid;
//Getters setters constructors
}
Jobs
#Entity
#Table(name = "jobs")
public class Jobs {
#Id
#Column(name = "jid")
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int jid;
#Column(name = "job_name")
private String job_name;
//Getters setters constructors
}
Credentials
#Entity
#Table(name = "credentials")
#IdClass(CredentialsCID.class)
public class Credentials {
#Id
#Column(name = "username")
private String username;
#Id
#Column(name = "is_admin")
private byte is_admin;
#Column(name = "password")
private String password;
#Column(name = "eid")
private int eid;
//Getters setters constructors
}
And this is the dto class
EmployeesCustomDTO
package com.example.accessingdatamysql.dto;
import com.example.accessingdatamysql.model.Contracts;
import com.example.accessingdatamysql.model.Credentials;
import com.example.accessingdatamysql.model.Employees;
public class EmployeesCustomDTO {
private int eid;
private String first_name;
private String last_name;
private String jid;
private int hours;
private String type;
private byte is_admin;
public EmployeesCustomDTO() {
}
public EmployeesCustomDTO(int eid, String first_name, String last_name, String jid, int hours, String type, byte is_admin) {
this.eid = eid;
this.first_name = first_name;
this.last_name = last_name;
this.jid = jid;
this.hours = hours;
this.type = type;
this.is_admin = is_admin;
}
public int getEid() {
return eid;
}
public void setEid(int eid) {
this.eid = eid;
}
public String getFirst_name() {
return first_name;
}
public void setFirst_name(String first_name) {
this.first_name = first_name;
}
public String getLast_name() {
return last_name;
}
public void setLast_name(String last_name) {
this.last_name = last_name;
}
public String getJob_name() {
return jid;
}
public void setJob_name(String job_name) {
this.jid = job_name;
}
public int getHours() {
return hours;
}
public void setHours(int hours) {
this.hours = hours;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public byte getIs_admin() {
return is_admin;
}
public void setIs_admin(byte is_admin) {
this.is_admin = is_admin;
}
public EmployeesCustomDTO convertToDTO(Employees employees, Credentials credentials, Contracts contracts){
EmployeesCustomDTO employeesCustomDTO = new EmployeesCustomDTO();
employeesCustomDTO.setEid(employees.getEid());
employeesCustomDTO.setFirst_name(employees.getFirst_name());
employeesCustomDTO.setLast_name(employees.getLast_name());
employeesCustomDTO.setJob_name(String.valueOf(employees.getJid())); // TODO: 19/12/2020 check if correct
employeesCustomDTO.setType(contracts.getType());
employeesCustomDTO.setHours(contracts.getHours());
employeesCustomDTO.setIs_admin(credentials.getIs_admin());
return employeesCustomDTO;
}
}
Then I added the following query to the EmployeesRepo (which works as I want it to when I try it on MySQL workbench)
#Repository
public interface EmployeesRepo extends JpaRepository<Employees, Integer> {
#Query(value = "SELECT employees.eid,employees.first_name,employees.last_name,employees.jid,contracts.hours,contracts.type,credentials.is_admin " +
"FROM employees,credentials,contracts " +
"WHERE employees.eid = credentials.eid AND contracts.eid = employees.eid", nativeQuery = true)
List<EmployeesCustomDTO> getCustomErgazomenoi();
}
and the following method in its service
#Override
public List<EmployeesCustomDTO> getCustomErgazomenoi() {
return employeesRepo.getCustomErgazomenoi();
}
which I then call in the controller
#GetMapping("/custom-employees")
public List<EmployeesCustomDTO> getAllCustomEmployees(){return employeesService.getCustomErgazomenoi();}
When I send the request to the endpoint I get the following error:
From Postman:
{
"timestamp": "2020-12-22T16:40:28.542+00:00",
"status": 500,
"error": "Internal Server Error",
"message": "",
"path": "/employees/custom-employees"
}
From the terminal in intellij

Even though I've found some answers on how to fix this problem I can't seem to get it to work on my API. Any suggestions?

Can you provide the code for EmployeesCustomDTO class? It looks like you are trying to perform a DTO projection which would require you to map the SQL result to the properties in the DTO.
If you are using hibernate you can create an appropriate constructor on the DTO and update query to use the new constructor:
#Query(value = "SELECT com.example.accessingdatamysql.dto.EmployeesCustomDTO(employees.eid,employees.first_name,employees.last_name,employees.jid,contracts.hours,contracts.type,credentials.is_admin) " +
"FROM employees,credentials,contracts " +
"WHERE employees.eid = credentials.eid AND contracts.eid = employees.eid")
List<EmployeesCustomDTO> getCustomErgazomenoi();
For a detailed explanation see - https://vladmihalcea.com/the-best-way-to-map-a-projection-query-to-a-dto-with-jpa-and-hibernate/
Either way, you must provide the mapping from the SQL result set to your DTOs properties. If you are following standard naming conventions in SQL and Java the names are likely not identical - e.g. your query references first_name but I assume your DTO will be firstName.
Looks like you can also provide the mapping via #SqlResultSetMapping if you are using native queries: https://thorben-janssen.com/dto-projections/#DTO_projections_for_native_SQL_queries

Spring data jdbc error BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar

I've below domain model objects, with below DDL and spring version, when i try to fetch the complete aggregate (just two entities) with my custom sql, spring-data returns below error.
when I remove the aggregate definition( i.e, remove the AppUsersAuth entity from my root Entity AppUsers, this method isEmailRegistered(String Email) works fine.
So I'm thinking that either i don't have my aggregates defined correctly or my DDL or hitting a blocker in spring-data-jdbc.
Any help, suggestion on this will be much appreciated.

Can't update a field in a PostgreSQL table

I'm trying to build a question answer website like Stack Overflow, to learn how RESTful web services work, it is my first time writing web services, I have already made the controller for asking the questions and answering them.
But there's a problem, which I had when I was making a REST Endpoint for the upvote, so whenever a user upvotes a question, I have to update the number of votes a question has in the questions table (at the start it is zero) but when I'm trying to hit the Endpoint for Upvote the update query which I have written throws an error and shows me the error page.
The error thrown:
org.postgresql.util.PSQLException: No results were returned by the query.

Code for the QuestionRepository which is used to update the votes:
package com.demo.beans.repository;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;
import org.springframework.stereotype.Repository;
import com.demo.beans.Question;
#Repository
public interface QuestionRepository extends JpaRepository<Question, Long> {
#Query(value = "SELECT * from questions where pr_key=:pr_key", nativeQuery = true)
public Question findByPrKey(#Param("pr_key") String prKey);
#Query(value = "UPDATE questions SET questionvotes=:questionvotes where pr_key=:pr_key", nativeQuery=true)
public void changeVotes(#Param("questionvotes") int questionVotes, #Param("pr_key") String prKey);
}
Here the second query is responsible for updating the votes.
I'm calling this function in the QuestionsController in this method:
#RequestMapping("/upvoteQuestion")
public String upvoteQuestion(#CookieValue(value = "username", defaultValue = "null") String username,
#CookieValue(value = "password", defaultValue = "null") String password, #Valid QuestionVote questionVote) {
System.out.println("works" + questionVote.getQuestionPrKey() + " " + questionVote.getUserPrKey());
if (!username.equals("null") && !password.equals("null")) {
// checks whether there is user with the username and password given
// by the cookie
if (userRepository.checkWhetherAccountExists(username, password).get(0) != null) {
questionVote.setUserPrKey(userRepository.findUsingUsername(username).getPrKey());
if (questionVoteRepository.checkUpvote(questionVote.getQuestionPrKey(), questionVote.getUserPrKey()).equals("false")) {
questionVoteRepository.vote("true", "false", questionVote.getQuestionPrKey(),questionVote.getUserPrKey());
System.out.println("Question PrKey: " + questionVote.getQuestionPrKey());
questionRepository.changeVotes(13, questionVote.getQuestionPrKey());
}
}
}
return "redirect:/questions/"+questionVote.getQuestionPrKey();
}
In the above code, the following line throws the error:
questionRepository.changeVotes(13, questionVote.getQuestionPrKey());
My Question class looks like this:

}
public int getQuestionVotes() {

}
public String getAcceptedAnswerStatus() {

}

}
}
And yes I have data in the table. What am I doing wrong, and how can I resolve it?
I have tried adding #Modifying too, still it throws the same error.
Edit
I have used the UPDATE Query to update other fields in a different table and it works, don't know why this doesn't work.
questionVoteRepository.vote("true", "false", questionVote.getQuestionPrKey(),questionVote.getUserPrKey());
check the above line of code in the method upvoteQuestion which added above, this lines works perfectly, updating the question_votes table.
The QuestionVote POJO looks like this:
package com.demo.beans;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import org.hibernate.annotations.GenericGenerator;
#Entity
#Table(name="question_votes")
public class QuestionVote {
#Id
#GeneratedValue(generator = "uuid")
#GenericGenerator(name = "uuid", strategy = "uuid2")
#Column(name = "PR_KEY")
private String prKey;
#Column(name="question_pr_key")
private String questionPrKey;
#Column(name="user_pr_key")
private String userPrKey;
#Column(name="upvote")
private String upvote;
#Column(name="downvote")
private String downvote;
public QuestionVote() {
}
public QuestionVote(String prKey, String questionPrKey, String userPrKey, String upvote, String downvote) {
super();
this.prKey = prKey;
this.questionPrKey = questionPrKey;
this.userPrKey = userPrKey;
this.upvote = upvote;
this.downvote = downvote;
}
public String getPrKey() {
return prKey;
}
public void setPrKey(String prKey) {
this.prKey = prKey;
}
public String getQuestionPrKey() {
return questionPrKey;
}
public void setQuestionPrKey(String questionPrKey) {
this.questionPrKey = questionPrKey;
}
public String getUserPrKey() {
return userPrKey;
}
public void setUserPrKey(String userPrKey) {
this.userPrKey = userPrKey;
}
public String getUpvote() {
return upvote;
}
public void setUpvote(String upvote) {
this.upvote = upvote;
}
public String getDownvote() {
return downvote;
}
public void setDownvote(String downvote) {
this.downvote = downvote;
}
}
When a question is added I add a row in the question_votes table too and set the upvote and downvote column for that row as false, false. When the question is upvoted I update the two tables questions and question_votes the question_votes table gets updated successfully but the questions table doesn't gets updated.
The QuestionVoteRepository looks like this:
package com.demo.beans.repository;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;
import org.springframework.stereotype.Repository;
import com.demo.beans.QuestionVote;
#Repository
public interface QuestionVoteRepository extends JpaRepository<QuestionVote, Long>{
#Query(value = "SELECT exists (SELECT 1 from question_votes where question_pr_key=:question_pr_key and user_pr_key=:user_pr_key)", nativeQuery=true)
public String checkWhetherRowExists(#Param("question_pr_key") String questionPrKey,
#Param("user_pr_key") String userPrKey);
#Query(value = "SELECT upvote from question_votes where question_pr_key=:question_pr_key and user_pr_key=:user_pr_key", nativeQuery=true)
public String checkUpvote(#Param("question_pr_key") String questionPrKey, #Param("user_pr_key") String userPrKey);
#Query(value = "SELECT downvote from question_votes where question_pr_key=:question_pr_key and user_pr_key=:user_pr_key", nativeQuery=true)
public String checkDownvote(#Param("question_pr_key") String questionPrKey, #Param("user_pr_key") String userPrKey);
#Query(value = "UPDATE question_votes SET upvote=:upvote, downvote=:downvote where question_pr_key=:question_pr_key and user_pr_key=:user_pr_key", nativeQuery=true)
public void vote(#Param("upvote") String upvote, #Param("downvote") String downvote,
#Param("question_pr_key") String questionPrKey, #Param("user_pr_key") String userPrKey);
}

You need to add #Modifying to changeVotes method in the repository to mark that this is an update query and no results are expected back.
