I am getting these error while integrating the spring-boot with JPA repository here is the code
@CrossOrigin(origins = "http://localhost:4200") @RestController @RequestMapping("/api") public class EmpController { @Autowired private CrudRepo crud; @Autowired private AddrCrudRepo addr; @Autowired private EntityManager entity; //@Autowired //private ModelMapper mapper; private static int count = 0; @Bean public ModelMapper model() { return new ModelMapper(); } //@Autowired // public EmpController(ModelMapper mapper) { // this.mapper = mapper; // } @RequestMapping(path = "/post-addr", method = RequestMethod.POST) public List<AddressModel> postAddr(@Valid @RequestBody List<AddressRequest> addr1){ // crud.findById(id) //AddressModel list = new AddressModel(); EmployeeModel emp = new EmployeeModel(); System.out.println("CALLING THE MAPPER "+addr1); List<AddressModel> addr_list = ObjectMapperUtils.mapAll(addr1, AddressModel.class); System.out.println("CALLED THE MAPPER "+addr_list); addr_list.forEach((a) -> { crud.findById(a.getEmpId()).ifPresent((b) -> { System.out.println(this.count++); a.setEmp_id(b); b.getAddress().add(a); }); }); // AddressModel addr_list = model().map(addr1, AddressModel.class); // // crud.findById(addr1.getEmp_id()).ifPresent((b) -> { // addr_list.setEmp_id(b); // // });`enter code here` System.out.println(addr_list.size()); List<AddressModel> addr3 = addr.saveAll(addr_list); System.out.println(addr3); return addr_list; } getting an error in the postAddr method as when it returns the List<AddressModel> and here is the AddressModel
@Entity @Table(name="Emp_Address") public class AddressModel implements Serializable{ @Column(name="address_id") @Id private Integer address_id; @Column(name="city") private String city; @Column(name="states") private String states; @Transient private Integer empId; @ManyToOne @JoinColumn(name="emp_id") private EmployeeModel emp_id; public AddressModel() { } //getter and setter and EmployeeModel
@Entity @Table(name="Employee") public class EmployeeModel implements Serializable{ @Column(name="Emp_id") @Id private Integer emp_id; @Column(name="Emp_Name") private String emp_name; @OneToMany(mappedBy="emp_id") private Collection<AddressModel> address = new ArrayList<>(); public EmployeeModel() { } //getter and setters so while saveAll is done properly but when the postAddr method returns the List it throws the StackOverflow
