Java 使用hibernate.cfg.xml时更改hibernate.properties文件的位置

我们在hibernate.cfg.xml中提供db凭证，如下所示

<hibernate-configuration>
    <session-factory>
       <property name="hibernate.connection.url">url</property>
       <property name="hibernate.connection.username">username</property>
       <property name="hibernate.connection.password">password</property>
    <session-factory>
<hibernate-configuration>

---

通过编程，您可以像这样加载XML和属性：

public class MyHibernate {

  private static final SessionFactory sessionFactory = buildSessionFactory();

  private static SessionFactory buildSessionFactory() {
    try {
        URL r1 = MyHibernate.class.getResource("/hibernate.cfg.xml");
        Configuration c = new Configuration().configure(r1);

        try {
            InputStream is = MyHibernate.class.getResourceAsStream("/hibernate.properties");
            Properties props = new Properties();
            props.load(is);
            c.addProperties(props);
        } catch (Exception e) {
            LOG.error("Error reading properties", e);
        }

        return c.buildSessionFactory();
    } catch (Throwable ex) {
        LOG.error("Error creating SessionFactory", ex);
        throw new ExceptionInInitializerError(ex);
    }
  }

  public static SessionFactory getSessionFactory() {
    return sessionFactory;
  }
}

通过春季

您可以使用PropertiesFactoryBean从文件中读取属性并配置LocalSessionFactoryBean：

<bean id="sessionFactory" class="org.springframework.orm.hibernate.LocalSessionFactoryBean">
    <property name="hibernateProperties">
      <bean class="org.springframework.beans.factory.config.PropertiesFactoryBean">
        <property name="location">path-to-properties-file</property>
      </bean>
    </property>
    ...
  </bean>
