Question

我是Hibernate的新手。当我使用Eclipse运行我的Hibernate程序时，它能够找到 hibernate.cfg.xml 文件。我将该文件放入 src / main / resources 文件夹中。但是当我创建可执行jar 并运行我的程序时 java -jar SQ.jar 它给了我以下错误

Exception in thread "main" java.lang.ExceptionInInitializerError

以下是我加载 hibernate.cfg.xml 文件的代码

private static SessionFactory buildSessionFactory() {
        try {
            // Create the SessionFactory from hibernate.cfg.xml
            return new AnnotationConfiguration().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);
        }
    }

请告诉我我做错了什么。

Answer 1

您可以在配置时提供完整路径。你可以试试这个。

return new AnnotationConfiguration().configure("/resources/hibernate.cfg.xml").buildSessionFactory();

or

return new AnnotationConfiguration().configure("hibernate.cfg.xml").buildSessionFactory();

Answer 2

如果您使用的是hibernate 4.3 +

，也可以试试这个

configuration = new Configuration();
configuration.configure("hibernate.cfg.xml");

StandardServiceRegistryBuilder serviceBuilder = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
sessionFactory = configuration.buildSessionFactory(serviceBuilder.build());

运行为可执行jar时找不到hibernate.cfg.xml
