JPARepository findAll() loop data

I have 3 entities:

SLUSER_INFO(SLUSER_INFO_ID, FULLNAME, FIRSTNAME, LASTNAME, ADDRESS, DOB) SLUSER(SLUSER_ID, PASSWORD, USERNAME, SLUSER_INFO_ID) SLROLE(SLROLE_ID, ROLENAME, SLUSER_ID) 

In User entity:

 @OneToMany(mappedBy = "user", cascade = CascadeType.ALL, orphanRemoval = true) @JsonView(SlUserView.Full.class) private List<SlRole> roles; @OneToOne(cascade = CascadeType.ALL) @JoinColumn(name = "SLUSER_INFO_ID", referencedColumnName = "SLUSER_INFO_ID") @JsonView(SlUserView.Full.class) private SlUserInfo userInfo; 

In Role entity:

@ManyToOne @JoinColumn(name = "SLUSER_ID", referencedColumnName = "SLUSER_ID") private SlUser user; 

and User_info entity

@OneToOne(mappedBy = "userInfo") private SlUser user; 

I create the rest api to get all user by using JPARepository findAll

@Repository public interface SlUserRepository extends JpaRepository<SlUser, Long> { } 

Controller

 public ResponseEntity<Page<SlUser>> findAll(Pageable pageable) { Page<SlUser> pageResult = usersRepository.findAll(pageable); return new ResponseEntity<Page<SlUser>>(pageResult, HttpStatus.OK); } 

try to run the rest api, the results are duplicated data.
