1、单向

（1）Husband类

package com.yy.hibernate.model;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.Id;import javax.persistence.JoinColumn;import javax.persistence.OneToOne;import javax.persistence.PrimaryKeyJoinColumn;@Entity(name="husband2")public class Husband {private int id;private String name;private Wife wife;@Id@GeneratedValuepublic int getId() {return id;}public String getName() {return name;}@OneToOne@PrimaryKeyJoinColumnpublic Wife getWife() {return wife;}public void setId(int id) {this.id = id;}public void setName(String name) {this.name = name;}public void setWife(Wife wife) {this.wife = wife;}}

（2）wife类

package com.yy.hibernate.model;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.Id;@Entity(name="wife2")public class Wife {private int id;private String name;@Id@GeneratedValuepublic int getId() {return id;}public void setId(int id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}}
