myeclipse中使用hibernate的异常（hibernate5.1）

1、当文件找不到时有可能是文件放置的路径不对
2、myeclipse需要自己创建.hbm.xml文件

<?xml version="1.0" encoding='UTF-8'?><!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN""http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"><!-- Generated May 22, 2016 11:40:35 PM by Hibernate Tools 3.5.0.Final --><hibernate-mapping>    <class name="Students" table="STUDENTS">        <id name="sid" type="int">            <column name="SID" />            <generator class="assigned" />        </id>        <property name="sname" type="java.lang.String">            <column name="SNAME" />        </property>        <property name="gender" type="java.lang.String">            <column name="GENDER" />        </property>        <property name="birthday" type="java.util.Date">            <column name="BRITHDAY" />        </property>        <property name="address" type="java.lang.String">            <column name="ADDRESS" />        </property>    </class></hibernate-mapping>

这个异常，我的是因为hbm.xml文件中写错了一个单词
