Hibernate Oracle Создать таблицу

Question

У меня проблема при создании таблицы в oracle через спящий режим. я получаю эти две ошибки:

Could not execute JDBC batch update 

и

ORA-00942: table or view does not exist 

Это мой hibernate.cfg.xml

<hibernate-configuration> 
    <session-factory> 
     <property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property> 
     <property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:ORCL</property> 
     <property name="hibernate.connection.username">system</property> 
     <property name="hibernate.connection.password">mypass</property> 
     <property name="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</property> 
     <property name="hibernate.default_schema">SamTest</property> 
     <property name="hibernate.connection.pool_size">5</property> 
       <property name="show_sql">true</property> 
     <property name="hibernate.hbm2ddl.auto">update</property> 

     <mapping class="com.sam.Teacher" /> 

    </session-factory> 
</hibernate-configuration> 

Учитель объект

@Table(schema="SamTest") 
public class Teacher { 

    @Id 
    //@GenericGenerator(name = "generator", strategy = "increment") 
    private int teacher_Id; 
    @Column 
    private int teacher_No; 
    @Column 
    private String teacher_Name; 
    @Column 
    private String teacher_Surname; 
    @Column 
    private String department; 


    public String getDepartment() { 
     return department; 
    } 

    public void setDepartment(String department) { 
     this.department = department; 
    } 

    public int getTeacher_Id() { 
     return teacher_Id; 
    } 

    public void setTeacher_Id(int teacher_Id) { 
     this.teacher_Id = teacher_Id; 
    } 

    public int getTeacher_No() { 
     return teacher_No; 
    } 

    public void setTeacher_No(int teacher_No) { 
     this.teacher_No = teacher_No; 
    } 

    public String getTeacher_Name() { 
     return teacher_Name; 
    } 

    public void setTeacher_Name(String teacher_Name) { 
     this.teacher_Name = teacher_Name; 
    } 

    public String getTeacher_Surname() { 
     return teacher_Surname; 
    } 

    public void setTeacher_Surname(String teacher_Surname) { 
     this.teacher_Surname = teacher_Surname; 
    } 

    public Teacher() { 
    } 

    public Teacher(int teacher_No, String teacher_Name, String teacher_Surname, String department) { 
     this.teacher_No = teacher_No; 
     this.teacher_Name = teacher_Name; 
     this.teacher_Surname = teacher_Surname; 
     this.department=department; 
    } 

}

Answer 1

Похоже, вы создаете методы получения и установки в спящем режиме, но я уверен, что вы не создаете таблицу. Это только ссылка на таблицу Oracle, которая, очевидно, не существует (пока). Следовательно, ошибка «Таблица или представление не существует».
