在我的Spring Boot Rest應用程序和json mysql中，onetoone映射不起作用

Question

一對一映射不起作用。這是我的編碼和json，是郵遞員發來的。 該值保存到mysql數據庫中，它唯一保存在我的第一個數據庫“ pharmacy”中，第二個Db未保存，即外鍵映射。 ;

json: {
    "pharmacyName":"test",
    "pharmacyaddress":{
   '     "pinCode":"600001",
          "address":"sample"

    }
}

第一實體

@Entity @Table(name = "pharmacy") 
public class PharmacyEntity{
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "phrm_id")
    private Long id;
    private String pharmacyName;
    @OneToOne(mappedBy = "pharmacyEntity", cascade = CascadeType.ALL, 
         fetch = FetchType.LAZY, optional = false)
     private PharmacyDetailsEntity pharmacyaddress;
    public PharmacyDetailsEntity getPharmacyaddress() {
        return pharmacyaddress;
    }

    public void setPharmacyaddress(PharmacyDetailsEntity pharmacyaddress) {
        this.pharmacyaddress = pharmacyaddress;
        pharmacyaddress.setPharmacyEntity(this);
    }

// Getter＆Setter}

第二實體；

@Entity
@Table(name = "phrm_details")
public class PharmacyDetailsEntity {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "phrm_dtls_id")
    private int id;

    @OneToOne(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
    @JoinColumn(name = "phrm_id", referencedColumnName = "phrm_id")
    private PharmacyEntity pharmacyEntity;

    @Column(name = "pin_code")
    private int pinCode;
    @Column(columnDefinition = "TEXT")
    private String address;


}

這是我的@Restcontroller，並且正在使用JPA存儲庫進行保存，還使用了服務和服務實現

my controller is

@RequestMapping(value = "/savepharmacy", method = RequestMethod.POST,consumes = "application/json", produces = "application/json")

public ResponseEntity<?> createPharmacy( @RequestBody PharmacyEntity pharmacyEntity) {
    try {

        PharmacyEntity ph = pharmacyservice.savePharmacy(pharmacyEntity);
        return new ResponseEntity<ProjectStatus>(HttpStatus.CREATED);
    } catch (Exception e) {
        return new ResponseEntity<CustomErrorType>( HttpStatus.BAD_REQUEST);
    }
}

Answer 1

您的映射是正確的。 在Dao中使用EntityManager。

PharmacyDaoImpl：

@Autowired
EntityManager entityManager;

@Override
public PharmacyEntity save(PharmacyEntity entity) {


    entityManager.persist(entity);
    return entity;
}

輸入數據 ：

{“ pharmacyName”：“測試”，“ pharmacyaddress”：{“ pinCode”：“ 600001”，“ address”：“樣本”}}

回應：

{“ id”：6，“ pharmacyName”：“ test”，“ pharmacyaddress”：{“ id”：6，“ pharmacyEntity”：null，“ pinCode”：600001，“ address”：“ sample”}}
