두 개의 엔티티가 있으며 아래 코드를 찾으십시오. 간략하게 보일러 플레이트 코드가 생략되었습니다.기본 테이블의 기본 키를 종속 테이블의 외래 키 필드로 전달해야합니다.
public class Customer implements java.io.Serializable {
private static final long serialVersionUID = 3116894694769321104L;
private short customerId;
private Address address;
private String firstName;
private String lastName;
private String email;
private boolean active;
private Date createDate;
private Date lastUpdate;
// Property accessors
@Id
@Column(name="customer_id", unique=true, nullable=false, insertable=true, updatable=true)
public short getCustomerId() {
return this.customerId;
}
public void setCustomerId(short customerId) {
this.customerId = customerId;
}
@ManyToOne(cascade={CascadeType.ALL},
fetch=FetchType.LAZY)
@JoinColumn(name="address_id", unique=false, nullable=false, insertable=true, updatable=true)
public Address getAddress() {
return this.address;
}
public void setAddress(Address address) {
this.address = address;
}
및 주소 클래스입니다 : 내가 주소 테이블에서 외래 키로 고객 ID를 지속 할 필요가
public class Address implements java.io.Serializable {
// Fields
private short addressId;
private short customerId;
private String address;
private String address2;
private String district;
private String postalCode;
private String phone;
private Date lastUpdate;
private Set<Customer> customers_1 = new HashSet<Customer>(0);
// Constructors
/** default constructor */
public Address() {
}
// Property accessors
@Id
@Column(name="address_id", unique=true, nullable=false, insertable=true, updatable=true)
public short getAddressId() {
return this.addressId;
}
public void setAddressId(short addressId) {
this.addressId = addressId;
}
/**
* ??????what goes here
*/
public short getCustomerId() {
return customerId;
}
/**
* @param customerId the customerId to set
*/
public void setCustomerId(short customerId) {
this.customerId = customerId;
}
