找不到hibernate.cfg.xml [英] hibernate.cfg.xml not found

问题描述

我是Hibernate的新手，阅读本书Hibernate的Java持久化，并试图从那里实现这个例子。到目前为止，我的Ant构建是成功的，但是当我尝试执行包含main方法的类时，我收到以下错误消息：

显然，休眠nate找不到我的配置文件，它位于根目录。

项目

  + lib 
<所有必需的库> 
 + src 
 + hello 
 HelloWorld.java 
 Message.java 
 message.hbm.xml 
 +持久性
 HibernateUtil.java 
 build.xml 
 hibernate.cfg.xml 
  

我的完整源代码可以在这里找到： http://pastebin.com/bGDUrxUf

我有一个运行MySQL服务器的数据库hibernateapp和表消息

感谢：）

解决方案

您的 hibernate.cfg.xml 需要位于 src 目录中;否则它不会被Ant的 copymetafiles target覆盖，所以它不会在你编译的类路径中结束。

I am new to Hibernate, reading this book "Java persistence with Hibernate" and I am trying to implement the example from there. So far my Ant build is successful, but when I try to execute the class containing the main method I am getting this error message:

It is clear that hibernate can't find my config file, which is located in the root dir.

Project

+lib
<all required libraries>
+src
  +hello
    HelloWorld.java
    Message.java
    message.hbm.xml
  +persistence
    HibernateUtil.java
build.xml
hibernate.cfg.xml

My the complete source code can be found here: http://pastebin.com/bGDUrxUf

I have a running MySQL server with a database hibernateapp and table messages

Thanks :)

解决方案

Your hibernate.cfg.xml needs to be inside the src directory; otherwise it's not covered by Ant's copymetafiles target, so it won't end up in your compiled classpath.
