刚从官网下了hibernate4.3.4,结果照着官网doc中的示例class,xml写报了两个错误,实在是头疼

实体类:
package cn.edu.jmu.hibernate.model;

public class Student {
    private int id;
    private String name;
    private int age;
    public int getAge() {
        return age;
    }
    public int getId() {
        return id;
    }
    public String getName() {
        return name;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public void setId(int id) {
        this.id = id;
    }
    public void setName(String name) {
        this.name = name;
    }
}
配置文件:hibernate.cfg.xml
<?xml version="1.0" encoding="UTF-8"?>

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

<hibernate-configuration>


<session-factory>

<!-- Database connection settings -->


<property name="connection.driver_class">com.mysql.jdbc.Driver</property>

<property name="connection.url">jdbc:mysql://localhost:3306/hibernate</property>

<property name="connection.username">root</property>

<property name="connection.password">root</property>

<!-- JDBC connection pool (use the built-in) -->


<!-- <property name="connection.pool_size">1</property>-->


<!-- SQL dialect -->


<property name="dialect">org.hibernate.dialect.MySQL5Dialect</property>

<!-- Enable Hibernate's automatic session context management -->


<!-- <property name="current_session_context_class">thread</property> -->


<!-- Disable the second-level cache -->

<mapping resource="cn/edu/jmu/hibernate/model/Student.hbm.xml"/>

<mapping class="cn.edu.jmu.hibernate.model.Student"/>

</session-factory>

</hibernate-configuration>
配置文件2:Student.hbm.xml
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://hibernate.

<hibernate-mapping package="cn.edu.jmu.hibernate.model">
    <class name="Student"><!-- 实体类名与表名一致可不写table属性 -->
        <id name="id" /><!--主键 -->
        <property name="name" column="name"/><!-- 类中的属性名,对应的数据库中的属性名 -->
        <property name="age" /><!-- 不写默认两者一样 -->
    </class>
   
</hibernate-mapping>
测试类:StudentTest
import org.hibernate.Session;
import org.hibernate.SessionFactory;

import java.util.*;

import cn.edu.jmu.hibernate.model.*;

import org.hibernate.boot.registry.StandardServiceRegistry;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.tutorial.util.HibernateUtil;

public class StudentTest {

    public static void main(String[] args) {
         Student st = new Student();
            st.setId(6);
            st.setName("哈哈");
            st.setAge(20);
            
            Session session = HibernateUtil.getSessionFactory().getCurrentSession();//报错之一:21行的。。。
            session.beginTransaction();

            session.save(st);

            session.getTransaction().commit();
    }
}
自定义类(测试类中要用到):HibernateUtil
package org.hibernate.tutorial.util;

import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;

public class HibernateUtil {

    private static final SessionFactory sessionFactory = buildSessionFactory();

    private static SessionFactory buildSessionFactory() {
            // Create the SessionFactory from hibernate.cfg.xml
           return new Configuration().configure().buildSessionFactory(
                new StandardServiceRegistryBuilder().build() );
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }

}
