UserController In this the getUsers method doesn't work and caused error


@RestController
@RequestMapping("user")
public class UserController {

    private final Logger log = LoggerFactory.getLogger(UserController.class);

    @Autowired
    private UserService userService;

    @Autowired
    private RoleService roleService;

    @PostMapping("/add")
    public MessageDto addUser(@RequestBody UserDto userDto)
    {
        log.info("Post call have been received at user/add with DTO " + userDto);
                                             //Set<UserRoleDomain>
        UserDomain userDomain = userService.mapUserDtoToDomain(userDto);
        return userService.add(userDomain, roleService.add(userDomain));
    }

    @GetMapping("/get/{userName}")
    public UserDto getUsers(@PathVariable("userName") String userName)
    {
        log.info("Get call have been received at user/get/ "+userName);
        return userService.getById(userName);
    }

}

It was working fine but i dont know what happened now – Irreligious
you have one or more relation is null you have field in database dont has forigen key check the filed in database or delete the relation result into dto – Whirligig
Show us RoleDomain.hashCode – Becky
in dto you have object has null when transfer from entity to dto – Whirligig
Also show UserRoleDomain.hashCode – Becky
I bet your RoleDomain have field with type UserRoleDomain and vice versa. Both of those classes use its corresponding field in hashCode calculation. – Becky
It's a good thing you came to Stack Overflow and reported this error to us. ;) Back on topic- a Stack overflow error in java means you've called too many methods without returning and your call stack has become too large. It can happen when your code is in an infinite loop calling a method over and over. – Barnard
Does this answer help you? https://mcmap.net/q/1475821/-hibernate-infinite-loop-recursion-in-many-to-many-relation – Barnard
You can check the other classes of my application here for having a clear understanding about the issue github.com/iqbalrohail/Exam-portal-backend – Irreligious
The problem was with @Data annotation which I were using earlier .. – Irreligious
It's recommended to post a minimum reproducible example when asking for help. Furthermore, please place the contents of RoleDomain.java into your question since it was required to understand the problem and was part of the solution. – Barnard

A Stack Overflow error happens when your code has called too many methods without returning and there are too many methods in the stack, causing it to overflow. This commonly happens when you have an infinite loop where a method calls itself repeatedly.

There is a loop happening in your hashCode method in com.examportal.examportalapi.domain.UserRoleDomain which calls com.examportal.examportalapi.domain.RoleDomain.hashCode.

You have the @Data lombok annotation in these two classes. Replace the @Data annotation with just the features you need in the classes. @Data generates hashCode methods that cause your problem. See the documentation: https://projectlombok.org/features/Data

have a look at my domain package and other classes here github.com/iqbalrohail/Exam-portal-backend – Irreligious
Hey I took a look and updated my answer, let me know if it's not resolved. @Rohail Iqbal – Barnard
yes i changed Data annotations in my whole code to simple Lombok annotations and it works for me ie; Setter- -Getter-- AllArgsConstructor --NoArgsConstructor-- ToString – Irreligious
This article (projectlombok.org/features/Data) helps me understanding why it is not good to use @Data , thanks CausingUnderflowsEverywhere – Irreligious
No problem @RohailIqbal remember to up vote helpful answers and down vote not helpful ones and choose an answer to mark as the solution before you go. – Barnard
I am a newbie on stack overflow so need some reputation ..if you find the question useful your up vote for the question would be appreciated . – Irreligious
I will leave some feedback. – Barnard

Changed @Data annotation with the following Lombok annotations and it worked for me

@Setter

@Getter

@AllArgsConstructor

@NoArgsConstructor

@ToString

@Entity

Irreligious answered 1/8, 2021 at 13:0 Comment(1)
use @Data in lombok – Dionysian

I encounter this problem and solved this problem with @Data annotation only so that you can solve this problem only @Data annotation as well. you have add @EqualsAndHashCode.Exclude and @ToString.Exclude in your entities.

may be useful. Today I lost a lot of time because i tried to print a List object. It was calling implicitely toString(), but the error came from Unit tests and it was not pointing directly to the class with the problem

List<ArticoliDto> articoli = articoliService.SelByDescrizione("blabla"); //return a List<xxx>
logger.info("Trovati articoli: " + articoli); //this causes the error!!

The exception was (partially):

I faced the same issue. after debugging found out that there was a cycle in my code. after fixing that the error was solved. Please, check for the cycle in your code too. maybe that's the issue.

when I upgraded the project I did face the same issue, adding "implementation 'org.apache.commons:commons-lang3:3.14.0'" in build.gradle helped me to solve the issue.

It will be great to have the code of the classes UserDomain and RoleDomain.

I've noticed a potential dependency between UserDomain and RoleDomain. Currently, when saving a UserDomain, it appears to be attempting manual role creation.

I suggest exploring the possibility of eliminating the manual role creation code. Instead, configure the system to handle role creation automatically through the ORM during the process of saving a UserDomain.
