ハイバネーションマッピング例外不明mappedBy

Question

こんにちは、私は間違って何をやっているのですか？ これらは私のクラスは次のとおりです。 と私はスレッドでそれを「メイン」org.hibernate.AnnotationExceptionを

例外を実行しようとすると、これは私が取得エラーです：不明mappedByで：hiberbiber.Student.studendetails、参照プロパティ不明：hiberbiber .StudenDetails.student

import java.util.Set; 
import javax.persistence.CascadeType; 
import javax.persistence.Column; 
import javax.persistence.Entity; 
import javax.persistence.FetchType;

import javax.persistence.Id; 
import javax.persistence.JoinColumn; 
import javax.persistence.JoinTable; 
import javax.persistence.OneToMany; 
import javax.persistence.OneToOne; 
import javax.persistence.Table; 


@Entity 
@Table(name = "STUDENT") 
public class Student implements Serializable { 

private long studentId; 
private String studentName; 
private Set<Phone> studentPhoneNumbers = new HashSet<>(0); 

private StudenDetails studendetails; 
public Student() { 
} 

public Student(String studentName, Set<Phone> studentPhoneNumbers) { 
    this.studentName = studentName; 
    this.studentPhoneNumbers = studentPhoneNumbers; 
} 

@Id 
@GeneratedValue()

    return this.studentId;

@OneToOne(fetch = FetchType.LAZY,mappedBy = "student",cascade = CascadeType.ALL)

} 



public void setStudendetails(StudenDetails studendetails) { 
    this.studendetails = studendetails; 
} 

public void setStudentId(long studentId) { 
    this.studentId = studentId; 
} 

public Student(long studentId, String studentName, StudenDetails studendetails) { 
    this.studentId = studentId; 
    this.studentName = studentName; 
    this.studendetails = studendetails; 
} 

@Column(name = "STUDENT_NAME", nullable = false, length = 100) 
public String getStudentName() { 
    return this.studentName; 
} 

public void setStudentName(String studentName) { 
    this.studentName = studentName; 
} 

@OneToMany(cascade = CascadeType.ALL) 
@JoinTable(name = "STUDENT_PHONE", joinColumns = { 
    @JoinColumn(name = "STUDENT_ID")}, inverseJoinColumns = { 
    @JoinColumn(name = "PHONE_ID")}) 
public Set<Phone> getStudentPhoneNumbers() { 
    return this.studentPhoneNumbers; 
} 

public void setStudentPhoneNumbers(Set<Phone> studentPhoneNumbers) { 
    this.studentPhoneNumbers = studentPhoneNumbers; 
} 
} 

そして、これは私はあなたが関係の両側にmappedByを持って

public class HiberBiber { 

/** 
* @param args the command line arguments 
*/ 
public static void main(String[] args) { 
    Session session = HibernateUtil.getFactory().openSession(); 
     Transaction tx = null; 
     try { 
      tx = session.beginTransaction(); 

      Set<Phone> phoneNumbers = new HashSet<Phone>(); 

      phoneNumbers.add(new Phone("house", "32333")); 
      phoneNumbers.add(new Phone("mobile", "06432333")); 


     Student student = new Student("eswar", phoneNumbers); 

     StudenDetails sd = new StudenDetails("123123", 13); 
     sd.setStudent(student); 

     student.setStudendetails(sd); 


     session.persist(student); 
     tx.commit(); 
     } catch (HibernateException e) { 
      tx.rollback(); 
     } finally{ 
      session.close(); 
     } 

    } 

} 

Answer 1

から実行するようにしようと試みたメインクラスです。あなたは両側のマッピングを使用している

@OneToOne(fetch = FetchType.LAZY,cascade = 
CascadeType.ALL) 
@PrimaryKeyJoinColumn 
public Student getStudent() { 
    return student; 
} 

と

@OneToOne(fetch = FetchType.LAZY, mappedBy="student",cascade = CascadeType.ALL) 
public StudenDetails getStudendetails() { 
    return studendetails; 
} 

Answer 2

：あなただけが所有している側であることを考えるの側にそれを設定します。片側に設定する必要があります。 StudentDetailsのStudentのマッピングを使用してください。

@OneToOne(fetch = FetchType.LAZY,cascade = CascadeType.ALL) 
@PrimaryKeyJoinColumn 
public Student getStudent() { 
    return student; 
}
