java - 找不到 Hibernate 异常 hibernate.cfg.xml

Question

我正在尝试使用 Hibernate 和 Maven 启动项目。

我遇到这样的异常:

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屏幕截图，(hibernate.cfg.xml 在 src/中): 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");

    }

}

该异常的来源可能是什么？

正如@JBNizet 所说，您的hibernate.cfg.xml 应该在src/main/resources 中。在 src 中，它不会被添加到运行时的类路径中。

如果您在 Eclipse 中运行您的项目，请不要忘记在构建路径配置的项目首选项中检查 src/main/resources 是否未从您的类路径中排除并且是确实是一个源文件夹。
