Handler dispatch failed; nested exception is java.lang.StackOverflowError with root cause

Getting this error when jpa tries to fetch the object from database.

Error : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Handler dispatch failed; nested exception is java.lang.StackOverflowError] with root cause

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));
    }

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.

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.

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.

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.

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):

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

@Setter

@Getter

@AllArgsConstructor

@NoArgsConstructor

@ToString

@Entity

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
