Hibernate异常hibernate.cfg.xml未找到 [英] Hibernate exception hibernate.cfg.xml not found

问题描述

我试图用Hibernate和Maven启动项目。

I'm trying to start project with Hibernate and Maven.

我有这样的例外：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
Exception in thread "main" org.hibernate.HibernateException: /hibernate.cfg.xml not found
    at org.hibernate.util.ConfigHelper.getResourceAsStream(ConfigHelper.java:170)
    at org.hibernate.cfg.Configuration.getConfigurationInputStream(Configuration.java:2176)
    at org.hibernate.cfg.Configuration.configure(Configuration.java:2157)
    at org.hibernate.cfg.Configuration.configure(Configuration.java:2137)
    at FirstHibernate.com.myhib.CRUDS.CrudsOps.main(CrudsOps.java:15)

这是我的项目结构的截图（hibernate.cfg.xml在src /）：

Here is the screenshot of my project structure, (hibernate.cfg.xml is in src/): http://imageshack.us/photo/my-images/692/screenshotxba.jpg/

CrudsOps.java

package FirstHibernate.com.myhib.CRUDS;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class CrudsOps {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub

        SessionFactory sf = new Configuration().configure().buildSessionFactory();
        System.out.println("Cfg and hbm files loaded succesfully");
        Session session = sf.openSession();
        session.beginTransaction();
        System.out.println("Transaction began");

    }

}

可能是该异常的来源？

What could be a source of that exception?

推荐答案

正如@JBNizet所说，你的 hibernate.cfg.xml 应该在src / main / resources中。在src中，不会将其添加到运行时的类路径。

As @JBNizet said, your hibernate.cfg.xml should be in src/main/resources. In src, it won't be added to your classpath for runtime.

如果您在Eclipse中运行项目，请勿忘记构建中的项目首选项路径配置，以检查 src / main / resources 是否从您的类路径中排除，确实是源文件夹。

If you are running your project within Eclipse, don't forget in the project preferences in the build path configuration to check that the src/main/resources is not excluded from your class path and is indeed a source folder.
