    org.hibernate.MappingException: Unknown entity: com.lzw.hibernate.helloworld.News


    当出现这种问题时候首先要检查两个地方:

    1  、 如果使用了 Entities 注解 ,要注意导入的包,不是hibernate 的包,而是java的

    2 、 检查 *.cfg.xml 和 *.hbm.xml 配置文件 书写是否正确 ,映射格式是否真确,ps: 检查正确与否 可以: 按着Ctrl 把鼠标移动到相应位置,如果出现下划线并且能够点击进去,说明映射文件配置正确。


    如果上述,不能解决问题,那么就要注意hibernate架包的使用版本 :



    //hibernate5 以后就要这样些代码了

     //创建服务注册对象
            ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().configure().build();
            //创建会话工厂对象
            SessionFactory sessionFactory = 
            new MetadataSources(serviceRegistry).buildMetadata().buildSessionFactory();


    // 2. 创建一个 session 对象
    Session session = sessionFactory.openSession();



    // 3. 开启事务

    Transaction transaction =  session.beginTransaction();

    // 4. 执行保存操作

    News news = new News("Java","lzw",new Date(new java.util.Date().getTime()));
    session.save(news);
    //
    // News news2 = session.get(News.class , 1);
    // System.out.println(news2);

    // 5. 提交事务
    transaction.commit();
    // 6 . 关闭session
    session.close();

    // 7. 关闭sessionFactory 对象
    sessionFactory.close();




    在hibernate 4.5以后,创建sessionFactory的时候就要用上述的方法来创建。

    希望对大家有用!

    Linux News: Developer: As the Software World Turns, Part 1: Engineers In, Programmers Out: "'While there will always be a role for superior technical ability, the developers and IT employees with the greatest potential will be the ones who can mix in-depth technology knowledge with business fluency. Yesterday's superstar programmers are becoming tomorrow's technology guides.'"
    软件设计与商业知识的结合
    If a programmer's job is simply a matter of receiving specs and turning in code, the odds are increasing that someone else is willing -- and capable -- of doing the same job for a lot less compensation.

    programmer 的层次
    The role of the software developer is changing. A programmer may be a developer, or an analyst may fill the role of an architect. The reason is the proliferation of diverse business needs. Gone are the days of simple client/server programming, when coders created Windows-based applications that made simple calls to the company's database.

    问题描述:

    Hibernate连接数据库时,报出如下错误:

    原因分析:

    查看报错信息:说是News类的属性date的非法声明异常,查看出现date的地方:

    55         sessionFactory.close();
    56     }
    57 
    58 }

    可以看出在News.java里的变量date导入的是java.sql.date包,在对应的News.hbm.xml文件里定义的变量date是java.util.Date类型,而在HibernateTest.java里传入的是java.sql.Timestamp。

          

    解决办法:

    将News.java里的date变量的包和其他文件一样统一成java.util.Date即可。
