내 코드에 문제가있다 ...봄 부팅 JSON many to one
Spring Boot 및 Angularjs로 단일 페이지 응용 프로그램을 만듭니다.
@Entity
@Table(name = "admins")
public class Admin {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer adminid;
private String name;
private String surname;
private String email;
private String login;
private String password;
@ManyToOne
@JoinColumn(name = "groupid")
private Group groupid;
private Boolean active;
@Temporal(TemporalType.TIMESTAMP)
private Date modifydate;
@Temporal(TemporalType.TIMESTAMP)
private Date createdate;
public Admin() {
}
//setters ang getters
}
그리고 내 secend 엔티티 클래스는 내가 가진이
{adminid: null, name: "dsa", surname: "dsa", email: "d", login: "sada", groupid: "1", active: true}
처럼
@Entity
@Table(name = "groups")
public class Group {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer groupid;
private String groupname;
@Temporal(TemporalType.TIMESTAMP)
private Date modifydate;
@Temporal(TemporalType.TIMESTAMP)
private Date createdate;
@OneToMany(fetch = FetchType.EAGER, mappedBy = "groupid")
@JsonIgnore
private List<Admin> groupusers;
public Group() {
}
public Group(Integer groupid) {
this.groupid = groupid;
}
}
내 프론트 엔드 응용 프로그램이 서버에 요청을 보낼 같습니다 여기
내 사용자 클래스입니다 새 관리자를 추가하려고하면 groupid 속성의 문제가 발생합니다 ...WARN 27742 --- [nio-8080-exec-8] .w.s.m.s.DefaultHandlerExceptionResolver : Failed to read HTTP message: org.springframework.http.converter.HttpMessageNotReadableException: Could not read document: Can not construct instance of com.patryk.model.Group: no String-argument constructor/factory method to deserialize from String value ('1')
at [Source: [email protected]; line: 1, column: 83] (through reference chain: com.patryk.model.Admin["groupid"]); nested exception is com.fasterxml.jackson.databind.JsonMappingException: Can not construct instance of com.patryk.model.Group: no String-argument constructor/factory method to deserialize from String value ('1')
at [Source: [email protected]; line: 1, column: 83] (through reference chain: com.patryk.model.Admin["groupid"])
내 컨트롤러 :
@RestController
@RequestMapping("/api/admins")
public class AdminController {
@Autowired
private AdminService adminService;
@RequestMapping(method = RequestMethod.POST)
public ResponseEntity<?> addUser(@RequestBody Admin admin)
{
adminService.save(admin);
return new ResponseEntity<Admin> (admin,HttpStatus.OK);
}
}
가 어떻게 해결책을 찾을 수 있습니까? 누구든지 내가 뭘 잘못하고 있는지 알아?
