在 Hibernate 中以编程方式设置属性 [英] Setting properties programmatically in Hibernate

问题描述

如何确保从 hibernate.cfg.xml 加载所有属性，然后以编程方式添加其他属性?我看到了以下代码片段，但它看起来像是一个全新的配置，而不是对现有配置的补充.

How can I ensure that all properties are loaded from hibernate.cfg.xml, then add additional properties programmatically? I saw the following code snippet but it looks like a completely new configuration, not an addition to an existing one.

Configuration c = new Configuration();
c.configure();

c.setProperty("hibernate.connection.username", "abc" );
c.setProperty("hibernate.connection.password", "defgh629154" ); 

推荐答案

您展示的代码片段正是您所需要的.只需使用您现有的配置，而无需创建新配置.

The code snippet you showed is what you need. Just use your existing configuration instead of creating a new one.

如果不是您实例化配置(但是，例如，spring)，您需要扩展创建它的类.

If it is not you who instantiates the configuration (but, for example, spring), you'd need to extend the class that creates it.
