Question

我需要在mysql表中一次保存两个实体。以下是两个实体一个是UserEntity，另一个是UserDetailsEntity。我想在UserDetails表中插入UserId列作为外键。但是UserDd没有插入UserDetails表中。在这个Plz中帮助我。

UserEntity.java

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "UserId")
private int id;

@Column(name = "UserLogin", length = 15, unique = true)
private long phNumber;

@Column(name = "Password", length = 100)
private String password;

@Column(name = "UserType", length = 20)
private String userType;

@Column(name = "PromoCode", length = 20)
private String promoCode;

@Column(name = "FirstName", length = 30)
private String firstName;

@Column(name = "LastName", length = 30)
private String lastName;

@Column(name = "RoleId")
private int roleId;

@Column(name = "isActive")
private int isActive;

@Column(name = "isTestUser")
private int isTestUser;

@Column(name = "FcmToken", length = 100)
private String fcmToken;

@OneToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "UserId", unique = true,insertable = true, updatable = true) 
//@ForeignKey(name = "UserId")
private UserDetailsEntity userDetailsEntity;

// getters and setters

UserDetailsEntity.java

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "UserDetailsId")
private int id;


@Column(name="UserId", unique=true, nullable=false)
@GeneratedValue(generator="gen")
@GenericGenerator(name="gen", strategy="foreign", parameters={@Parameter(name="property", value="uid")})    
private int userId;

@Column(name ="AadhaarCardNumber" ,length = 12)
private long aadhaarNumber;

@Column(name="", length = 50)
private String emailId; 

@Column(name="Address1" , length = 30)
private String address1;

@Column(name="Address2", length = 30)
private String address2;

@Column(name="CityId", length = 10)
private int cityId;

@Column(name="StateId", length = 10)
private int stateId;

@Column(name="CountryId", length = 10)
private int countryId;

@Column(name="Latitude", length = 60)
private String lat;

@Column(name="Longitude", length = 60)
private String lng;

@Column(name="MobileNumber1", length = 15)
private long mobileNumber1;

@Column(name="MobileNumber2", length = 15)
private long mobileNumber2;

@Column(name="DOB", length = 15)
private Date dob;

@OneToOne   
private UserEntity userEntity;

// getter and setters here

我自己找到了解决方案。让我更新。只需在parent表中提及注释OneToOne（这里是Users）。和UserDetails的Id的子表将存储在父表中。 <ImageView android:id="@+id/imageView" android:layout_width="match_parent" android:layout_height="wrap_content" android:scaleType="centerCrop" android:layout_marginTop="50dp" app:srcCompat="@drawable/login_bottom_coloured_line" />
我的要求已经完成，与UserDetailsEntity无关。

外键关系：单向注释休眠
