8.1.1 Hibernate：一对一单向关联（unidirectional）

本文主要是介绍8.1.1 Hibernate：一对一单向关联（unidirectional），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

将 @OneToOne 放在表 phone_detail 的映射类中，因为外键定义在 phone_detail 表中。

1 定义映射类
1.1 表 phone 的映射类定义：

package hibernate;import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;@Entity
@Table(name = "phone")
public class Phone {@Id@GeneratedValue(strategy = GenerationType.IDENTITY)@Column(name = "id")private int id;@Column(name = "imei")private String imei;@Column(name = "number")private String number;public Phone() {}public Phone(String imei, String number) {this.imei = imei;this.number = number;}// 省略 Getters 和 Setters ...}

1.2 表 phone_detail 的映射类定义：

package hibernate;import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.OneToOne;
import javax.persistence.Table;@Entity
@Table(name = "phone_detail")
public class PhoneDetail {@Id@GeneratedValue(strategy = GenerationType.IDENTITY)@Column(name = "id")private int id;@OneToOne(cascade = CascadeType.ALL)@JoinColumn(name = "phone_id")private Phone phone;@Column(name = "manufacturer")private String manufacturer;@Column(name = "model")private String model;public PhoneDetail() {}public PhoneDetail(String manufacturer, String model) {this.manufacturer = manufacturer;this.model = model;}// 省略 Getters 和 Setters ...}

2 测试
2.1 新增
2.1.1 同时新建两个对象并建立引用关系，插入 Phone 对象

package hibernate;import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.junit.Test;public class HibernateTest {@Testpublic void test() {Configuration configuration = new Configuration().configure("hibernate.cfg.xml");SessionFactory sessionFactory = configuration.buildSessionFactory();Session session = sessionFactory.openSession();Transaction transaction = session.beginTransaction();Phone phone = new Phone("812345678912345", "18012345678");PhoneDetail phoneDetail = new PhoneDetail("XXX", "XXX-2017");phoneDetail.setPhone(phone);session.save(phone);transaction.commit();session.close();sessionFactory.close();}}

运行测试，从日志中可以看出，实际上 Hibernate 只向 phone 表中插入了一条数据，并未向 phone_detail 表中插入任何数据。

2.1.2 同时新建两个对象并建立引用关系，插入 PhoneDetail 对象
将单元测试中 session.save(phone); 替换成 session.save(phoneDetail);
运行测试，从日志中可以看出，Hibernate 不仅向 phone_detail表中插入了一条数据，还向 phone 表中插入关联数据，由此可见 PhoneDetail 类维护级联关系。

注意：@OneToOne 的 cascade 属性一定要设置，否则会出现以下异常导致两条数据全部插入失败！@OneToOne 的 cascade 属性后续将详细阐述。

2.2 删除
基于以上测试新增的数据进行删除测试。
2.2.1 修改单元测试代码，删除 Phone

@Test
public void test() {Configuration configuration = new Configuration().configure("hibernate.cfg.xml");SessionFactory sessionFactory = configuration.buildSessionFactory();Session session = sessionFactory.openSession();Transaction transaction = session.beginTransaction();Phone phone = (Phone) session.createQuery(" FROM Phone").list().get(0);session.delete(phone);transaction.commit();session.close();sessionFactory.close();
}

2.2.2 修改单元测试代码，删除 PhoneDetail

@Test
public void test() {Configuration configuration = new Configuration().configure("hibernate.cfg.xml");SessionFactory sessionFactory = configuration.buildSessionFactory();Session session = sessionFactory.openSession();Transaction transaction = session.beginTransaction();PhoneDetail phoneDetail = (PhoneDetail) session.createQuery(" FROM PhoneDetail").list().get(0);session.delete(phoneDetail);transaction.commit();session.close();sessionFactory.close();
}

运行测试，从日志中看出只删除了 PhoneDetail 对象映射的 phone_detail 表中记录，其关联的 phone 表中记录未被删除。

2.3 更新
基于新增测试的数据进行更新测试。
2.3.1 同时修改持久化的 Phone 和 PhoneDetail 对象，更新 Phone

@Test
public void test() {Configuration configuration = new Configuration().configure("hibernate.cfg.xml");SessionFactory sessionFactory = configuration.buildSessionFactory();Session session = sessionFactory.openSession();Transaction transaction = session.beginTransaction();PhoneDetail phoneDetail = (PhoneDetail) session.createQuery(" FROM PhoneDetail").list().get(0);phoneDetail.setManufacturer("YYY");phoneDetail.setModel("YYY-2017");Phone phone = phoneDetail.getPhone();phone.setImei("987654321987654");phone.setNumber("13987654321");session.update(phone);transaction.commit();session.close();sessionFactory.close();
}

运行测试，从日志中可以看出两张表中记录级联更新了。

2.3.2 同时修改持久化的 Phone 和 PhoneDetail 对象，更新 PhoneDetail
将单元测试中 session.update(phone); 替换成 session.update(phoneDetail);，运行测试，从日志中可以看出，两张表也都级联更新了。

2.4 查询
基于新增测试的数据进行查询测试。

@Test
public void test() {Configuration configuration = new Configuration().configure("hibernate.cfg.xml");SessionFactory sessionFactory = configuration.buildSessionFactory();Session session = sessionFactory.openSession();Transaction transaction = session.beginTransaction();PhoneDetail phoneDetail = (PhoneDetail) session.createQuery(" FROM PhoneDetail").list().get(0);System.out.println("Phone Detail:");System.out.println(phoneDetail);transaction.commit();session.close();sessionFactory.close();
}

运行测试，日志如下：
