问题描述
我正在尝试使用hibernate制作一个maven登录应用程序，以将数据持久存储到mysql数据库中.我将应用程序部署在glassfish服务器上.我能够启动服务器并在html表单上填写数据，但是一旦提交表单，就会收到以下错误日志:
I am trying to make a maven login application using hibernate to persist the data onto a mysql database. I am deploying the application on a glassfish server. I am able to start the server and fill in data on the html form but once I submit the form, I get the following error logs:

我已经将hibernate.cfg.xml文件的位置从根文件夹移到了资源文件夹，也移到了资源文件夹，但是问题仍然存在，我也将cfg.xml文件的路径添加到了.configure()方法，但是没有用.我查看了所有先前询问的问题: ConfigurationException:无法找到cfg.xml资源[项目根文件夹2中的hibernate.cfg.xml]
I have moved the location of the hibernate.cfg.xml file from root folder, to the resource folder and also into the resource folder but problem prevails I have also added path of the cfg.xml file to the .configure() method, but did not work. I have looked at all the previously asked questions: ConfigurationException: Could not locate cfg.xml resource [hibernate.cfg.xml] in project root folder 2

但没有给出的解决方案可以解决我的问题.
but non of the solutions given fix my problem.
下面是我的实体类代码.
Below is my code for my entity class.
package model;
import javax.persistence.Entity;
import javax.persistence.Id;
import org.hibernate.annotations.NamedQueries;
import org.hibernate.annotations.NamedQuery;
@Entity
@NamedQueries({
@NamedQuery(name="getUserByUserNameAndPassword",
query="SELECT u FROM User u WHERE u.userName = :uname AND u.password = :pword")
})
public class User{
@Id
private Long userId;
private String firstName;
private String lastName;
private String userName;
private String password;
public User() {
}
//Getters and setters
}
下面是休眠util类.
Below is by hibernate util class.
package model;
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
public class HibernateUtil {
private static final SessionFactory sessionFactory;
private static final ServiceRegistry serviceRegistry;
static {
Configuration conf = new Configuration();
conf.configure();
serviceRegistry = new StandardServiceRegistryBuilder().applySettings(conf.getProperties()).build();
try {
sessionFactory = conf.buildSessionFactory(serviceRegistry);
} catch (Exception e) {
System.err.println("Initial SessionFactory creation failed." + e);
throw new ExceptionInInitializerError(e);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
下面是我的hibernate.cfg.xml
Below is my hibernate.cfg.xml
<?xml version="1.0" encoding="utf-8"?>

我的servlet类
package model;

protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

response.getWriter().append("Served at: ").append(request.getContextPath());

PrintWriter out = response.getWriter();
String fName = request.getParameter("firstName");
String uName = request.getParameter("userName");
String lName = request.getParameter("lastName");
String password = request.getParameter("password");
User user = new User();
user.setFirstName(fName);
user.setLastName(lName);
user.setUserName(uName);
user.setPassword(password);
RegisterService rs = new RegisterService();
if (!rs.isExistingUser(user.getUserName())) {//if user does NOT exist, then we register them
rs.registerUser(user);//register the user first
out.println("<h1>Registration Successful</h1>");
out.println("To login with new UserId and Password<a href=login.jsp>Click here</a>");
out.println("</center>");
out.println("</body>");
out.println("</html>");
out.close();
}else{//if user already exist
out.println("<h1>Username Exists!!</h1>");
out.println("To try again<a href=register.jsp>Click here</a>");
//RequestDispatcher d = request.getRequestDispatcher("index.jsp");
//d.forward(request, response);
}
//doGet(request, response);
}
}
我的服务等级:
package model;
import org.hibernate.Session;
public class RegisterService {
public boolean isExistingUser(String uname) {
Session session = HibernateUtil.getSessionFactory().openSession();
session.beginTransaction();
User user = (User) session.getNamedQuery("getUser").setParameter("uname", uname).uniqueResult();
session.getTransaction().commit();
session.close();
if (user.getUserName() != uname) {
return false;
}
return true;
}
public void registerUser(User user) {
if (!isExistingUser(user.getUserName())) {
Session session = HibernateUtil.getSessionFactory().openSession();
session.beginTransaction();
session.saveOrUpdate(user);
session.getTransaction().commit();
session.close();
}
}
}
最后是我的pom.xml
and finally my pom.xml

推荐答案
将Hibernate.cfg.xml放入项目的src文件夹中，并按如下所示更新代码，并检查其是否有效. SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory(); 这将自动获取.cfg文件，而无需提及它.
Put your Hibernate.cfg.xml in src folder of your project and update the code as below and check if it works. SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory(); This will automatically fetch the .cfg file without mentioning it.
