javax.naming.NoInitialContextException：需要在环境或系统属性中指定类名

标签： java hibernate jndi

我正在尝试用Hibernate做一个简单的应用程序。我创建了hibernate.cfg.xml和映射文件Personne.hbm.xml。一旦我启动它，我得到一个异常javax.naming.NoInitialContextException：需要在环境或系统属性中指定类名...

详细说明： 我得到的错误是：

答案 0 :(得分：1)

既然你说你刚刚开始学习Hibernate，我认为你并没有故意试图创建一个JNDI绑定的SessionFactory：

<session-factory
        name="java:hibernate/SessionFactory">

我可以看到这是Hibernate官方文档的副本。在那里，作者解释说，通过这个命名，您将把SessionFactory绑定到JNDI上下文。这正是对你不起作用的，因为你还没有配置。最简单的解决方案实际上就是删除name参数并停止尝试进行绑定。
