hibernate.cfg.xml 在项目中的位置? [英] Location of hibernate.cfg.xml in project?

问题描述

我创建了一个具有以下结构的项目:

I created a project with following structure:

HibernateUtil:

HibernateUtil:

public class HibernateUtil {

    private static final SessionFactory sessionFactory = buildSessionFactory();

    private static SessionFactory buildSessionFactory() {
        try {
            // Create the SessionFactory from hibernate.cfg.xml
            Configuration  configuration = new Configuration().configure( "C:\Users\Nikolay_Tkachev\workspace\hiberTest\src\logic\hibernate.cfg.xml");
            return new Configuration().configure().buildSessionFactory();
        } catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    public static void shutdown() {
        // Close caches and connection pools
        getSessionFactory().close();
    }

}

在线

Configuration  configuration = new Configuration().configure( "C:\Users\Nikolay_Tkachev\workspace\hiberTest\src\logic\hibernate.cfg.xml");

我有错误

错误的原因是什么，我该如何解决?

What is the reason for the error and how do I fix it?

推荐答案

给出相对于你的项目的路径.

Give the path relative to your project.

在您的 src 中创建一个名为 resources 的文件夹并将您的配置文件放在那里.

Create a folder called resources in your src and put your config file there.

   configuration.configure("/resources/hibernate.cfg.xml");

如果你检查你的代码

Configuration  configuration = new Configuration().configure( "C:\Users\Nikolay_Tkachev\workspace\hiberTest\src\logic\hibernate.cfg.xml");
return new Configuration().configure().buildSessionFactory();

您在两行中创建了两个配置对象.

In two lines you are creating two configuration objects.

如果你写，那应该可以工作(没有测试过)，

That should work(haven't tested) if you write,

Configuration  configuration = new Configuration().configure( "C:\Users\Nikolay_Tkachev\workspace\hiberTest\src\logic\hibernate.cfg.xml");
return  configuration.buildSessionFactory();

但是在服务器上部署后失败，因为您使用的是系统路径而不是项目相对路径.

But It fails after you deploy on the server,Since you are using system path than project relative path.
