org.hibernate.internal.util.config.ConfigurationException: 找不到 cfg.xml 资源 [hibernate.cfg.xml]
org.hibernate.internal.util.config.ConfigurationException: Could not locate cfg.xml resource [hibernate.cfg.xml]
我正在尝试完成以下项目，使用休眠和 java 注释更新具有一对多和多对一关系的数据库，不带 hbm 文件。一个用户可以拥有多台笔记本电脑。我的项目在 NetBeans、eclipse 上运行良好。如何在网络中抛出以上错误 IDE。我在代码中遗漏了什么吗？

请在提供任何输入之前注意一些事项 -:
1> 我的hibernate.cfg.xml在src文件夹
2> 我确实尝试过配置 ("hibernate.cfg.xml") 甚至完整路径
3> 我的项目在 IDE 中运行良好，例如 NetBeans 和 eclipse 在网络中无法运行 ide
如果我遗漏了什么，请帮助我
因为您已经为您的问题尝试了很多解决方案，但这些都不适用于您的项目。因此，我正在分享您可以做的一些事情。请检查这是否可以帮助...
1> 将您的配置文件移动到您的主项目文件夹，然后提供配置路径（“hibernate.cfg.xml”）如果在错误消息中抛出错误检查它采用什么路径作为默认路径（错误消息将向您展示路径以及错误）。如果它不采用默认路径，请尝试提供完整路径。也可以在下面尝试使用参考路径作为 ...
File f = new File(""hibernate.cfg.xml"");
Configuration config = new Configuration().configure(f).addAnnotatedClass(User.class)
.addAnnotatedClass(Laptop.class);
有时有效:)
2> 尝试使用 java 配置检查数据库是否准备就绪，但没有 hibernate.cfg.xml 文件。你可以尝试如下..（如果使用任何其他数据库，下面基于 mysql chnage 详细信息）
Configuration cfg = new Configuration()
.addAnnotatedClass(your clas)
.addAnnotatedClass(your clas)
.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect")
.setProperty("hibernate.connection.driver_class", "com.mysql.jdbc.Driver")
.setProperty("hibernate.connection.url", "jdbc:mysql://localhost:3306/yourdb")
.setProperty("hibernate.connection.username", "your username")
.setProperty("hibernate.connection.password", "your password")
.setProperty("hibernate.hbm2ddl", "create")
.setProperty("hibernate.show_sql", "true");
cfg.configure();
SessionFactory sf = cfg.buildSessionFactory();
Session session = sf.openSession();
Transaction tx = session.beginTransaction();
在这里至少您会了解您的问题。
希望这有助于解决您的问题。
