Test.java另一个版本
public class TEST {
public static void main(String[] args){
Configuration configuration = new Configuration().configure(); //.addAnnotatedClass(Users.class); //with configure("hibernate.cfx.xml still not working
ServiceRegistry serviceRegistry
= new StandardServiceRegistryBuilder()
.applySettings(configuration.getProperties()).build();
// builds a session factory from the service registry
SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);
try{
Users user = new Users(1,"login","password","mail",null);
Session session = sessionFactory.openSession();
session.beginTransaction();
session.save(user);
}catch (Exception e){
System.out.println("blad\n\n");
System.out.println(e);
} finally {
System.out.println("zrobiono");
}
}}
有一个错误
org.hibernate.MappingException: Unknown entity: com.serwis.model.Users
但是
Configuration configuration = new Configuration().configure().addAnnotatedClass(Users.class);
再多一次

blad
org.hibernate.exception.SQLGrammarException: could not prepare statement
答案 0 :(得分：0)
我不知道我必须告诉hibernate制作表格，我认为Hibernate会自动完成。
我添加到hibernate.cfg.xml
<property name="hibernate.hbm2ddl.auto">update</property>
