Issue
This is not the same problem as this. Following the answer here, if I add spring.jpa.properties.javax.persistence.validation.mode=none then my custom validator is not even invoked.
Use Case
- My Table has 3 columns - id, role and user_id. Now there can be only 1 row for which role can take the value ROLE_ROOT. And once that record is inserted, it can't be updated.
How I am trying to implement
- Using custom javax.validation.ConstraintValidator and checking if record is present for role=ROLE_ROOT inside
isValid
(I know there are alternatives to do this. like, before calling repository.save(..), call repository.findByRole(..) , check and restrict. But I want to understand why this scenario is failing.)
What error I am getting
java.lang.StackOverflowError: nulland the line~~~~~~validation checkis being printed hundreds of times.
My Code
MyController class
@RestController
public class MyController {
@Autowired
private MyTableRepository repository;
@GetMapping("/hello")
public void hello() {
MyEntity myEntity = new MyEntity();
myEntity.setId(123456);
myEntity.setRole("ROLE_ROOT");
myEntity.setUserId(3);
repository.save(myEntity);
}
}
MyRepository class
@Repository
public interface MyTableRepository extends JpaRepository<MyEntity, Integer> {
List<MyEntity> findByRole(String roleName);
}
MyEntity class
@Entity
@Table(name = "my_table")
public class MyEntity {
@Id
@Column(name = "id")
private int id;
@Column(name = "role")
@CheckRole
private String role;
@Column(name = "user_id")
private int userId;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getRole() {
return role;
}
public void setRole(String role) {
this.role = role;
}
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
}
My Custom Annotation
@Target({ FIELD, ANNOTATION_TYPE, METHOD, PARAMETER })
@Retention(RUNTIME)
@Constraint(validatedBy = RoleValidator.class)
public @interface CheckRole {
String message() default "{org.hibernate.validator.referenceguide.chapter06.CheckCase.message}";
Class<?>[] groups() default { };
Class<? extends Payload>[] payload() default { };
}
My Custom Validator class
public class RoleValidator implements ConstraintValidator<CheckRole, String> {
private final MyTableRepository repository;
public RoleValidator(MyTableRepository repository) {
this.repository = repository;
}
@Override
public void initialize(CheckRole constraintAnnotation) {
}
@Override
public boolean isValid(String value, ConstraintValidatorContext context) {
if(value.equals("ROLE_ROOT")){
System.out.println("~~~~~~validation check");
return (repository.findByRole("ROLE_ROOT").size() > 0);
}
else {
return true;
}
}
}
My ValidatorAddingCustomizer (following this question)
@Component
public class ValidatorAddingCustomizer implements HibernatePropertiesCustomizer {
private final ObjectProvider<Validator> provider;
public ValidatorAddingCustomizer(ObjectProvider<javax.validation.Validator> provider) {
this.provider = provider;
}
public void customize(Map<String, Object> hibernateProperties) {
Validator validator = provider.getIfUnique();
if (validator != null) {
hibernateProperties.put("javax.persistence.validation.factory", validator);
}
}
}
Hibernate validator version: 5.2.4.Final Spring boot version: 2.3.1.RELEASE
Here is friendpaste link containing all the code.
A followup question on this is:
If I mark the id column of MyEntity as @GeneratedValue(strategy = GenerationType.IDENTITY) , with rest of the code intact, then the error changes to the below one
org.hibernate.AssertionFailure: null id in com.example.schooltimetable.entity.MyEntity entry (don't flush the Session after an exception occurs)

Solution
AutoFlush on before query execution and Another query execution attempt on AutoFlush recursion
- You try to save your entity and
preInsertvalidation is triggered. - In validation, you are doing a query on the same entity which means before doing the query, hibernate need to flush what is queued in your session.
- Trying to flush causes the
preInsertvalidation again and this repeats.
One way to stop Auto flush on query
- Unfortunately you have to add a method like this to your repository to stop
autoFlush()happening for that query.
@Query("Select count(m) from MyEntity m where m.role = :roleName")
@Transactional(propagation = Propagation.NOT_SUPPORTED)
Long count(String roleName);
- When the query is made non transactionally, hibernate doesn't need to flush before the query and so it will not go into recursion.
