java - 找不到 hibernate.cfg.xml - java 中的异常

Question

我正在创建一个简单的应用程序来学习 Hibernate。我正在使用 NetBeans IDE，并在 com.hibernate 包中创建了一个类。该类定义为:

package com.hibernate;

import com.mahesh.entity.UserDetails; 

import org.hibernate.SessionFactory; 
import org.hibernate.cfg.Configuration;
import org.hibernate.classic.Session;

public class hibr {
    public static void main(String[] args) {
        UserDetails user = new UserDetails();
        user.setUserID(1);
        user.setUserName("Mahesh");

        SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
        Session session = sessionFactory.openSession();
        session.beginTransaction();
        session.save(user);
        session.getTransaction().commit();
    }
}

我已将 UserDetails 类定义为:

package com.mahesh.entity;

import javax.persistence.Entity;
import javax.persistence.Id;

/**
 *
 * @author Mahesh
 */
@Entity
public class UserDetails {
    @Id
    private int userID;
    private String userName;

    public void setUserID(int userID) {
        this.userID = userID;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public int getUserID() {
        return userID;
    }

    public String getUserName() {
        return userName;
    }
}

我已经定义了一个位于 src 文件夹(默认包)中的 hibernate.cfg.xml 文件

这是 NetBeans IDE 生成的错误。

Answer 1

尝试

new Configuration().configure(<your cfg file path>).buildSessionFactory();
