线程“主”org.hibernate.UnknownEntityTypeException中的异常:无法找到持久化程序
线程“主”org.hibernate.UnknownEntityTypeException中的异常:无法找到持久化程序
提问于 2015-12-07 07:12:31
我不得不问，我几乎什么都试过了。
实体类
@Entity
@Table(name="UserInfo")
public class User {
@Id@Column(name="user_name")
private String userName;
@Column(name="user_id")
private Integer userId;
}<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
<property name="hibernate.connection.url">jdbc:sqlserver://localhost:1433;databaseName=BankingApplication</property>
<property name="hibernate.connection.username">sa</property>
<property name="hibernate.connection.password">2OmniWay</property>
<!-- org.hibernate.HibernateException: No CurrentSessionContext configured! -->
<property name="hibernate.current_session_context_class">thread</property>
<property name="hibernate.default_schema">dbo</property>
<!-- Mapping with model class containing annotations -->
<mapping class="pojo.User"/>
</session-factory>
</hibernate-configuration>SeesionFactory
// Create the SessionFactory from hibernate.cfg.xml
Configuration configuration = new Configuration();
configuration.configure("hibernate-annotation.cfg.xml");
System.out.println("Hibernate Annotation Configuration loaded");
ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder(). applySettings(configuration.getProperties()).build();
System.out.println("Hibernate Annotation serviceRegistry created");
SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);
return sessionFactory;获取数据库中保存的对象
SessionFactory sessionFactory = HibernateUtil.getSessionAnnotationFactory();
Session session = sessionFactory.openSession();
Account account = null;
try{
account = (Account) session.get(Account.class, id);我在主题上被提到了例外。我只是检查了三倍，检查了所有东西，但都不起作用。
任何建议都会有帮助。

您需要在配置中专门添加实体类。默认情况下，它加载类，但不初始化实体类。对于这个问题，configuration.addAnnotatedClass()或addResource将解决这个问题。

替换您的代码
"ServiceRegistry serviceRegistry =新的serviceRegistry
从SessionFactory到
serviceRegistry serviceRegistry=新的ServiceRegistryBuilder().applySettings( configuration.getProperties()). buildServiceRegistry()；
并尝试使您的sessionfactory和serviceRegistry在课堂上保持静态。
希望它对你有用。

//I am using Hib5,I have created SF like this and it is working
private static SessionFactory sessionFactory;
public static SessionFactory getSessionFactory() {
if (sessionFactory == null) {
StandardServiceRegistry standardRegistry = new StandardServiceRegistryBuilder().configure().build();
Metadata metadata = new MetadataSources(standardRegistry).getMetadataBuilder().build();
sessionFactory = metadata.getSessionFactoryBuilder().build();
}
return sessionFactory;
