Question

当我使用hibernate.properties文件时，我可以从Configuration对象成功创建一个SessionFactory：

Configuration configuration = new Configuration()
                .addAnnotatedClass(WeatherResponse.class);
SessionFactory sessionFactory = configuration.buildSessionFactory();

然而，我想使用typesafe配置库而不是hibernate.properties，以便能够将配置作为环境变量传递，因此我删除了hibernate.properties并以编程方式设置属性如下：

Configuration configuration = new Configuration()
                .addAnnotatedClass(WeatherResponse.class)
                .setProperty("hibernate.connection.username", config.getString("user"))
                .setProperty("hibernate.connection.password", config.getString("pass"))
                .setProperty("hibernate.connection.driver_class", config.getString("driver"))
                .setProperty("hibernate.connection.url", config.getString("url"))
                .setProperty("hibernate.dialect", config.getString("dialect"));
SessionFactory sessionFactory = configuration.buildSessionFactory();

但即使我在我的属性文件中设置了所有属性，我也会收到错误：

我正在使用hibernate-core 5.2.2.Final和hibernate-annotations 3.5.6-Final和mysql-connection-java 6.0.3并使用Guice进行依赖注入，而不使用Spring。

Answer 1

我在错误中注意到了这一点：

java.lang.ClassNotFoundException: org.hibernate.cfg.Mappings

我可以通过删除hibernate-annotations依赖来解决问题，因为hibernate-core 5.2已经包含了它。

Hibernate程序配置无法正常工作
