hibernate配置文件找不到映射文件user.hbm.xml

Question

请各位高手帮忙解决下：
hibernate.cfg.xml文件如下：
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"><!-- Generated by MyEclipse Hibernate Tools.                   -->
<hibernate-configuration><session-factory>
<property name="connection.username">sa</property>
<property name="connection.url">
jdbc:microsoft:sqlserver://7FACED93D6344FF:1433;databasename=stu
</property>
<property name="dialect">
org.hibernate.dialect.SQLServerDialect
</property>
<property name="myeclipse.connection.profile">
SQLServerDriver
</property>
<property name="connection.driver_class">
com.microsoft.jdbc.sqlserver.SQLServerDriver
</property>
<mapping resource="com/User.hbm.xml" /></session-factory></hibernate-configuration>
映射文件user.hbm.xml文件如下：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-mapping>
<class name="com.User" table="course">
<id name="sno">
<generator class="identity"/>
</id>
<property name="sname"/>
<property name="ssex"/>
<property name="sage"/>
</class>
</hibernate-mapping>
User类如下：
package com;public class User {
private int sno;
private String sname;
private String ssex;
private int sage;
public int getSage() {
return sage;
}
public void setSage(int sage) {
this.sage = sage;
}
public String getSname() {
return sname;
}
public void setSname(String sname) {
this.sname = sname;
}
public int getSno() {
return sno;
}
public void setSno(int sno) {
this.sno = sno;
}
public String getSsex() {
return ssex;
}
public void setSsex(String ssex) {
this.ssex = ssex;
}}
测试类如下：
package com;import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;public class Test {
public static void main(String []args)
{
try
{
SessionFactory sf=new Configuration().configure().buildSessionFactory();
Session session=sf.openSession();
Transaction tx=session.beginTransaction();
User user=new User();
user.setSname("励志");
user.setSsex("男");
user.setSage(25);
session.save(user);
tx.commit();
session.close();
}
catch(HibernateException e)
{
e.printStackTrace();
}
}
}
错误信息如下：

Answer 1

配置文都有错误o.. 不是找不到配置文件,而是不能读取.因为你写错了..
 你刚学hibernate ? <property name="sname"> 
<property name="ssex"/> 
<property name="sage"/>   你的属性要指列数据库中的列呀..
  <property name = "sname" type = "java.lang.String">
     <cloumn name = "你的列名" lenght = "">
  </property>

你这个 直接在 hibernate 左下下面有个Configuration-“Mappings”-“Add”把你的 entity中的hbm.xml文件都添加进去找不到手写也可以
<mapping resource="com/xxxx/entity/xxxx.hbm.xml" />
<mapping resource="com/xxxx/entity/xxxx.hbm.xml" />
<mapping resource="com/xxxx/entity/xxxx.hbm.xml" />
