我在服务器启动时收到异常。（服务器使用Intelij IDE启动）。我不知道如何解决它。我是冬眠和春天的新手。提前致谢。休眠+春季例外：未知实体

请问您可以添加'com.jsi.core.dbservice.model.Authentication' Java类吗？ – andyb

您是否将身份验证注释为“@ Entity”bean？ –

是的。我添加了@Entity注释。 – user619237

谢谢大家对您的回复。我设法解决它。这是我的错误。我忘了在xml中添加映射标签。

<hibernate-configuration> 
    <session-factory> 
    <mapping class="com.model.Authentication"/> // i missed this line. after i added it. it worked fine. 
    </session-factory> 
</hibernate-configuration>

再次感谢。

如果你碰巧使用的HibernateUtil操纵数据，你需要注解的类添加到您的配置。

import org.hibernate.SessionFactory; 
import org.hibernate.cfg.AnnotationConfiguration; 

public class HibernateUtil { 
    private static final SessionFactory sessionFactory; 
    static { 
     try { 
      sessionFactory = new AnnotationConfiguration().addAnnotatedClass(Authentication.class) 
      .configure() 
        .buildSessionFactory(); 
     } catch (Throwable ex) { 
      System.err.println("Initial SessionFactory creation failed." + ex); 
      throw new ExceptionInInitializerError(ex); 
     } 
    } 

    public static SessionFactory getSessionFactory() { 
     return sessionFactory; 
    } 
}
