必须声明元素类型“hibernate-configuration”

在我的代码中，我试图从数据库映射person_details。配置文件是如下的hibernate.cfg.xml必须声明元素类型“hibernate-configuration”

<?xml version="1.0" encoding="utf-8"?> 
<!DOCTYPE hibernate-configuration SYSTEM 
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> 

<hibernate-configuration> 
<session-factory> 
    <property name="dialect"> 
     org.hibernate.dialect.MySQLDialect 
    </property> 
    <property name="connection.driver_class"> 
     com.mysql.jdbc.Driver 
    </property> 

    <!-- Assume test is the database name --> 
    <property name="connection.url"> 
     jdbc:mysql://localhost/EMP 
    </property> 
    <property name="connection.username"> 
     root 
    </property> 
    <property name="connection.password"> 
     root 
    </property> 


    <!-- List of XML mapping files --> 
    <mapping resource="employee.hbm.xml" /> 
    <mapping class="newmavenproject.hibernateexample.CRUDS.Employee" /> 

</session-factory> 
</hibernate-configuration>

映射XML文件如下

employee.hbm.xml

<?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"> 

<hibernate-mapping> 
<class table="Employee" name="newmavenproject.hibernateexample.CRUDS.Employee"> 
    <id name="id" type="int" column="id"> 
    <generator class="native"/> 
    </id> 
    <property name="age" column="age" type="int"/> 
    <property name="firstName" column="first" type="string"/> 
    <property name="lastName" column="last" type="string"/> 

</class> 
</hibernate-mapping>

上运行的应用我正在下面错误。请帮忙，因为我无法找到任何解决这个问题的方法。

你试图定义一个Hibernate的配置，但DTD文件你在XML中引用错误地指向http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd。将您的DOCTYPE声明更改为

<!DOCTYPE hibernate-configuration PUBLIC 
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN" 
    "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
