Hibernate注释一对一单向

为什么我在一对一hibernate映射示例中得到以下4条sql语句单向，对于简单hbm配置中的相同示例，我只得到2条insert语句

注释sql语句如下所示：

休眠：从PersonDetail persondeta中选择persondeta.id，persondeta.fatherName作为fatherName1，persondeta.motherName作为motherName1，PersonDetail persondeta.id=

Hibernate：插入个人电子邮件、名字、姓氏、个人详细信息、id值？、？、？、？、

Hibernate：在PersonDetail中插入父名、母名、id值？、？、

Hibernate:更新人员集电子邮件=？，firstName=？，lastName=？，personDetail\u id=？其中id=

对于HBMSQL语句，如下所示

Hibernate：插入个人电子邮件、名字、姓氏、id值？、？、？、

Hibernate：在PersonDetail中插入父名、母名、id值？、？、

我的hbm配置如下

}

包com.patel.model

导入javax.persistence.Column

导入javax.persistence.Entity

导入javax.persistence.Id

@实体

公共类个人信息{

@Id
private int id;
@Column
private String fatherName;
@Column
private String motherName;

public PersonDetail() {
    super();
}

public PersonDetail(int id, String fatherName, String motherName) {
    super();
    this.id = id;
    this.fatherName = fatherName;
    this.motherName = motherName;
}

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public String getFatherName() {
    return fatherName;
}

public void setFatherName(String fatherName) {
    this.fatherName = fatherName;
}

public String getMotherName() {
    return motherName;
}

public void setMotherName(String motherName) {
    this.motherName = motherName;
}

@Override
public String toString() {
    return "PersonDetail [id=" + id + ", fatherName=" + fatherName
            + ", motherName=" + motherName + "]";
}

}

下面是导致查询的代码

package com.patel.client

导入org.hibernate.Session

导入org.hibernate.SessionFactory

导入org.hibernate.Transaction

导入org.hibernate.TransactionException

导入org.hibernate.cfg.AnnotationConfiguration

导入com.patel.model.Person

导入com.patel.model.PersonDetail

公共类JpaClient{

public static void main(String[] args) {

    SessionFactory sf = new AnnotationConfiguration().configure().buildSessionFactory();
    Session session = sf.openSession();

    Transaction tx = null;

    try {
        tx = session.beginTransaction();

        Person p = new Person(1, "Bhupati", "Patel", "xyz@xyz.com");
        PersonDetail pd = new PersonDetail(1, "Bhupatis's Father", "Bhupati's Mother");
        p.setPersonDetail(pd);

        session.save(p);
        session.save(pd);
        tx.commit();
        System.out.println("Inserted");

    } catch (TransactionException e) {
        e.printStackTrace();
        tx.rollback();
    }

}

}

在hbm文件的客户端代码中：

SessionFactory sf=new Configuration.configure.buildSessionFactory

其余的都一样

使用哪种注释配置，我将得到两条insert语句作为hbm配置？

导致执行这些查询的代码在哪里？我刚刚添加了它。尝试将optional=false添加到OneTONE注释中。添加后会出现以下错误，我正在粘贴其中的一部分Hibernate:select personeda_uu2;id，PersonDetail PersonDetail persondeta_uuu中的persondeta.fatherName作为fatherName1_u，persondeta_uu.motherName作为motherName1_u，PersonDetail persondeta.id=？线程主org.hibernate.PropertyValueException中的异常：not null属性引用空值或临时值：com.patel.model.Person.PersondetailPersondetailPersondetail必须首先保存PersonDetail，因为此人引用了它。

@Id
private int id;
@Column
private String fatherName;
@Column
private String motherName;

public PersonDetail() {
    super();
}

public PersonDetail(int id, String fatherName, String motherName) {
    super();
    this.id = id;
    this.fatherName = fatherName;
    this.motherName = motherName;
}

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public String getFatherName() {
    return fatherName;
}

public void setFatherName(String fatherName) {
    this.fatherName = fatherName;
}

public String getMotherName() {
    return motherName;
}

public void setMotherName(String motherName) {
    this.motherName = motherName;
}

@Override
public String toString() {
    return "PersonDetail [id=" + id + ", fatherName=" + fatherName
            + ", motherName=" + motherName + "]";
}

public static void main(String[] args) {

    SessionFactory sf = new AnnotationConfiguration().configure().buildSessionFactory();
    Session session = sf.openSession();

    Transaction tx = null;

    try {
        tx = session.beginTransaction();

        Person p = new Person(1, "Bhupati", "Patel", "xyz@xyz.com");
        PersonDetail pd = new PersonDetail(1, "Bhupatis's Father", "Bhupati's Mother");
        p.setPersonDetail(pd);

        session.save(p);
        session.save(pd);
        tx.commit();
        System.out.println("Inserted");

    } catch (TransactionException e) {
        e.printStackTrace();
        tx.rollback();
    }
