我正在尝试从Hibernate和Maven开始项目。
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"); } }

该异常的根源可能是什么?
正如@JBNizet所说,您hibernate.cfg.xml应该位于src / main / resources中。在src中,不会将其添加到运行时的类路径中。
hibernate.cfg.xml
如果您正在Eclipse中运行项目,请不要忘记构建路径配置中的项目首选项,以检查src/main/resources并没有将其从类路径中排除,并且确实是源文件夹。
src/main/resources
