Hibernate使用注解设定关联关系

@Entity
@Table(name="EMPLOYEE")
public class Employee {

@Id
@GeneratedValue
@Column(name="employee_id")
private Long employeeId;

@Column(name="name")
private String name;

@OneToOne(mappedBy="employee", cascade=CascadeType.ALL)
private EmployeeDetail employeeDetail;

public Employee() {

}

// Getter and Setter methods
}

@Entity
@Table(name="EMPLOYEEDETAIL")
public class EmployeeDetail {

@Id
@Column(name="employee_id", unique=true, nullable=false)
@GeneratedValue(generator="gen")
@GenericGenerator(name="gen", strategy="foreign", parameters=@Parameter(name="property", value="employee"))
private Long employeeId;

@Column(name="street")
private String street;

@OneToOne
@PrimaryKeyJoinColumn
private Employee employee;

public EmployeeDetail() {

}

// Getter and Setter methods
}
