是否必须有hibernate.cfg.xml文件进行配置 [英] Is it mandatory to have hibernate.cfg.xml file for configuration

问题描述

我不想有hibernate.cfg.xml文件。而我想通过我的代码做所有的配置如下所示。

I do not want to have the hibernate.cfg.xml file. Rather I want to do all the configuration through my code as shown below.

private static final SessionFactory factory;
private static final Properties properties;

static
{
    properties = new Properties();
    properties.setProperty("hibernate.connection.driver_class", "com.mysql.jdbc.Driver");
    properties.setProperty("hibernate.connection.url", "jdbc:mysql://localhost:3306/books");
    properties.setProperty("hibernate.connection.username", "jhtp7");
    properties.setProperty("hibernate.connection.password", "password");
    properties.setProperty("hibernate.show_sql", "com.mysql.jdbc.Driver");
    properties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");

    factory = new Configuration().setProperties(properties).configure().
                            buildSessionFactory();
}

我已经尝试了上述方法。但我面临的问题，hibernate抛出一个异常说 ./ hibernate.cfg.xml文件丢失。

I have tried the above approach. But I am facing the problem where hibernate throws an exception saying "./hibernate.cfg.xml file missing".

保存 hibernate.cfg.xml 文件真的是强制性的吗？

Is it really mandatory to keep the hibernate.cfg.xml file?

推荐答案

我相信这是因为您 configure（） c $ c>配置对象。尝试删除它，并且hibernate将不会查找不存在的文件。基本上你通过属性对象设置所有必需的属性，所以没有什么真正需要告诉Hibernate寻找 hibernate.cfg.xml 文件，这正是 configure（）方法。

I believe it is because of your configure() call on the Configuration object. Try removing that and hibernate will not look for the non-existent file. Basically you are setting all the required properties via your properties object so there is no real need to tell Hibernate to look for a hibernate.cfg.xml file which is exactly what the configure() method does.
