正如您所看到的,我有一个HibernateUtil,用于将数据保存到我的数据库中。我在userBean.save方法中使用的代码与我在junit测试中使用的代码相同。在我下面的junit测试中它完美无缺。但是,当我尝试在我的命令按钮中调用userBean.save方法时,它给出了一个错误,org.hibernate.HibernateException:/hibernate.cfg.xml未找到。
经过一些调试后,我可以告诉你hibernateUtil类中发生的错误,configuration.configure()。addAnnotatedClass(userBean.class);
如果我将commandbutton操作更改为welcome(这是我的欢迎页面的名称),表单可以通过将我重定向到欢迎页面并且在页面上输出bean值来正常工作。就我而言,这意味着bean已被正确初始化。 这非常令人困惑,为什么它在我的junit测试中而不是在我的jsf页面上工作?
public class HibernateUtil {
private static final SessionFactory sessionFactory = buildSessionFactory();
private static ServiceRegistry serviceRegistry;
private static SessionFactory buildSessionFactory() {
try {
Configuration configuration = new Configuration();
configuration.configure().addAnnotatedClass(userBean.class);
serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry();
SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);
// Create the SessionFactory from hibernate.cfg.xml
return sessionFactory;
}
catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}

正如我所说,问题来自于 。configuration.configure()addAnnotatedClass(userBean.class);
因此,当我们跨越这段代码时,我接受了调试器并复制了控制台输出。 以下是工作Junit测试的输出

实际上这里是我的文件夹结构的图像,显示了我的src和部署的资源
答案 0 :(得分:2)
问题的原因是JUnit找不到hibernate.cfg.xml
。发生这种情况,因为您将所有*.xml
资源放入WEB-INF/classes
文件夹。在这种情况下,这些资源在Web应用程序的类路径中可见,但在JUnit测试中不可见。
作为一种解决方案,我建议您按照以下方式进行:
*.xml
资源从WEB-INF/classes
移至源文件夹根目录。*.xml
个文件作为最终结果,您的*.xml
资源无论如何都位于WEB-INF/classes
文件夹中,但您也可以从普通类路径中获取这些资源。
请注意,您需要移动文件,否则可能会出现版本混乱。
