hibernate.cfg.xml没有找到hibernate.properties文件 [英] hibernate.cfg.xml does not find hibernate.properties file

问题描述

我们曾经在我们的Java源文件夹的同一个文件夹中有hibernate.cfg.xml和hibernate.properties文件。现在我将hibernate.properties文件移动到另一个位置。我如何使hibernate.cfg.xml文件再次找到hibernate.properties文件？我收到一个错误，似乎表明它不再被发现。

解决方案

编程方式，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）; 
配置c =新配置（）。configure（r1）; 
 
 try {
 InputStream is = MyHibernate.class.getResourceAsStream（/ hibernate.properties）; 
属性props = new Properties（）; 
 props.load（is）; 
 c.addProperties（道具）; 
} catch（Exception e）{
 LOG.error（Error reading properties，e）; 
} 
 
 return c.buildSessionFactory（）; 
} catch（Throwable ex）{
 LOG.error（Error Creating SessionFactory，ex）; 
抛出新的ExceptionInInitializerError（ex）; 
 
 
 
 public static SessionFactory getSessionFactory（）{
 return sessionFactory; 
 
 
  

希望它有用。

We used to have the hibernate.cfg.xml and hibernate.properties files in the same folder in our Java source folder. Now I moved the hibernate.properties file to another location. How can I make the hibernate.cfg.xml file find the hibernate.properties file again? I get an error which seems to indicate that it is not found anymore.

解决方案

Programmatically, you can load XML and properties like this:

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;
  }
}

Hope it be useful.
