org.hibernate.hql.internal.ast.QuerySyntaxException: Kreis ist nicht zugeordnet [aus Kreis]

Question

Ich baue eine Probe Frühling Winterschlaf Anwendung.Spring Teil funktioniert gut.Im Ruhezustand habe ich die Bean-Klasse und die Tabelle zugeordnet. Immer noch bekomme ich eine Fehlermeldung, dass die Bean-Klasse nicht zugeordnet ist. Bitte finden Sie den angehängten Code als Referenz.

Circle.java 

    package re.test; 
    import javax.persistence.Entity; 
    import javax.persistence.Id; 
    import org.hibernate.annotations.*; 
    import javax.persistence.Table; 
    @Entity 
    @Table(name = "EmployeeMaster1") 
    public class Circle { 
    @Id 
    private int id; 
    private String name; 

    public 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; 
    } 

    } 

HibernateDAOImpl.java 

    package re.test; 
    import org.hibernate.Query; 
    import org.hibernate.SessionFactory; 
    import org.springframework.beans.factory.annotation.Autowired; 
    import org.springframework.stereotype.Repository; 
    @Repository 
    public class HibernateDAOImpl { 

    @Autowired 
    private SessionFactory sessionFactory; 

    public void setSessionFactory(SessionFactory sessionFactory) 
    { 
     this.sessionFactory = sessionFactory; 
    } 
    public SessionFactory getSessionFactory() 
    { 
     return sessionFactory; 
    } 

    public int getTableCount() 
    { 
     System.out.println("test"); 
     String varSql = "from Circle"; 
     Query query = getSessionFactory().openSession().createQuery(varSql); 
     return ((Long) query.uniqueResult()).intValue();    
    } 
    } 

JDBCDemo.java 
    package re.test; 
    import org.springframework.context.ApplicationContext; 
    import org.springframework.context.support.ClassPathXmlApplicationContext; 

    public class JDBCDemo { 
    public static void main(String[] args) { 
     ApplicationContext ctx = new  ClassPathXmlApplicationContext("Spring.xml"); 
     HibernateDAOImpl dao = ctx.getBean("hibernateDaoImpl",HibernateDAOImpl.class); 
     int cnt = dao.getTableCount(); 
    } 
    }

Answer 1

Frühling ist dieser Fehler, da Ihre Bohne nicht in der spring.xml registriert ist. Da Sie eine XML-basierte Konfiguration verwenden, überprüfen Sie bitte die Spring-Klassen. Es sollte ähnlich aussehen:

<beans:bean id="hibernate4AnnotatedSessionFactory" 
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> 
    <beans:property name="dataSource" ref="dataSource" /> 
    <beans:property name="annotatedClasses"> 
     <beans:list> 
      <beans:value>com.mypackage.model.Person</beans:value> 
     </beans:list> 
    </beans:property> 
    <beans:property name="hibernateProperties"> 
    <beans:props> 
    <beans:prop key="hibernate.dialect"> 
       org. hibernate.dialect. MySQLDialect 
      </beans:prop> 
      <beans:prop key="hibernate.show_sql">true</beans:prop> 
     </beans:props> 
    </beans:property> 
</beans:bean>
