    import javax.persistence.Embedded;
    import javax.persistence.Entity;
    import javax.persistence.GeneratedValue;
    import javax.persistence.Id;
    import javax.persistence.JoinColumn;
    import javax.persistence.JoinColumns;
    import javax.persistence.OneToOne;

    @Entity
    public class Husband {
        private int id;
        private String name;
        private Wife wife;
        @Id
        @GeneratedValue
        public int getId() {
            return id;
        }
       
        public String getName() {
            return name;
        }
        @Embedded
        public 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;
        }
    }

    package com.bjsxt.hibernate;

     

    public class Wife {
       
        private String wifeName;
        private int age;
       
        public int getAge() {
            return age;
        }
        public void setAge(int age) {
            this.age = age;
        }
           
        public String getWifeName() {
            return wifeName;
        }
        public void setWifeName(String name) {
            this.wifeName = name;
        }
       
    }

    Husband.hbm.xml

     

    <?xml version="1.0"?>
    <!DOCTYPE hibernate-mapping PUBLIC
            "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
            "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

    <hibernate-mapping>
        <class name="com.bjsxt.hibernate.Husband" >
            <id name="id">
                <generator class="native"></generator>
            </id>
           
            <property name="name"></property>
            <component name="wife">
