【问题描述】:
这个问题只发生在这个控制器上,因为我在模型中添加了一个自我关系。
我在其他帖子和谷歌中阅读和搜索,任何解决方案似乎都有效。
我尝试设置@JsonIdentityInfo,添加@JsonBackReference 和@JsonManagedReference,颠倒此标签的顺序,将消耗添加到rest 方法,但一切正常
型号:
@Entity
@JsonIdentityInfo(
generator = ObjectIdGenerators.PropertyGenerator.class,
property = "code")
@Table (name = "EP7_TRS_CODIGOS")
public class Code implements Serializable {
private static final long serialVersionUID = 2L;
@Id
@Column (name = "COD_CODIGO")
private String code;
@Column (name = "DES_CODIGO")
private String description;
@Column (name = "COD_TIPO")
private String type;
@JsonManagedReference
@ManyToOne
@JoinColumn (name = "ID_ORIGEN", referencedColumnName = "ID_ORIGEN")
private Origin origin;
@JsonBackReference
@ManyToOne
@JoinColumn (name="COD_CODIGO_OBJ", referencedColumnName = "COD_CODIGO")
private Code parent;
@JsonManagedReference
@OneToMany (mappedBy = "parent", fetch = FetchType.LAZY)
private List<Code> sons;
控制器:
@PostMapping(value = "/code",
consumes = MediaType.APPLICATION_JSON_UTF8_VALUE,
produces = {MediaType.APPLICATION_JSON_UTF8_VALUE})
public ResponseEntity<Code> saveOrUpdateCode (@RequestHeader HttpHeaders httpHeaders, @RequestBody Code code){
logger.info(">>>> Entra en el controlador saveOrUpdateCode");
if (httpHeaders == null || !authorized(httpHeaders)) {
logger.error(">>>> Error de autentificacion");
return new ResponseEntity<>(HttpStatus.UNAUTHORIZED);
}
return new ResponseEntity<>(cs.save(code), HttpStatus.CREATED);
}
起源类
@Entity
// @JsonIdentityInfo(
// generator = ObjectIdGenerators.PropertyGenerator.class,
// property = "id")
@Table (name = "EP7_TRS_ORIGEN")
public class Origin implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@Column (name = "ID_ORIGEN")
private int id;
@Column (name = "DES_ORIGEN")
private String description;
@Column (name = "COD_TIPO")
private String type;
@JsonBackReference
@OneToMany (targetEntity=Code.class, mappedBy="origin", fetch = FetchType.LAZY)
private List<Code> codes;
