Java org.hibernate.MappingNotFoundException
我正在尝试做一个简单的hibernate程序。我正在按照本文中给出的步骤进行操作 我得到的错误是Java org.hibernate.MappingNotFoundException,java,hibernate,Java,Hibernate,我正在尝试做一个简单的hibernate程序。我正在按照本文中给出的步骤进行操作 我得到的错误是 org.hibernate.MappingNotFoundException: resource: org.manu.dtd.UserDetails not found at org.hibernate.cfg.Configuration.addResource(Configuration.java:799) at org.hibernate.cfg.Configuration

这是我的文件夹结构
我的带注释的persistence类是
package org.manu.dtd;
import javax.persistence.Entity;
import javax.persistence.Id;
@Entity
public class UserDetails {
@Id
private int userId;
private String userName;
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
}
我的hibernate.cfg.xml文件是
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

任何人都可以帮助我解决这个问题。为hibernate配置映射文件提供完全限定的名称
SessionFactory sF = new Configuration().
configure("/org/manu/dtd/hibernate.cfg.xml").buildSessionFactory();
看来可以更容易地修复。您应该使用
而不是
,因为资源用于映射描述实体等的其他xml文件。这是官方教程中的一个小例子当我像上面提到的那样放置路径时,错误是线程“main”org.hibernate.hibernate Exception:/org/manu/dtd/hibernate.cfg.xml中的异常未找到
我应用了上述修复,并将此
放入hibernate.cfg.xml文件中,效果非常好,谢谢。
SessionFactory sF = new Configuration().
configure("/org/manu/dtd/hibernate.cfg.xml").buildSessionFactory();
