segue abaixo meus arquivos:

Aluno.java

public class Aluno {

	private int alu_codigo;
	private String alu_nome;

	public int getAlu_codigo() {
		return alu_codigo;
	}

	public void setAlu_codigo(int alu_codigo) {
		this.alu_codigo = alu_codigo;
	}

	public String getAlu_nome() {
		return alu_nome;
	}

	public void setAlu_nome(String alu_nome) {
		this.alu_nome = alu_nome;
	}

}

hibernate.cfg.xml

<?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">
        
        

<hibernate-configuration>

	<session-factory>


		<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
		<property name="hibernate.connection.url">jdbc:mysql://localhost/tarefateste</property>
		<property name="hibernate.connection.username">root</property>
		<property name="hibernate.connection.password">123098</property>
		<property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>

		<mapping resource="aluno.hbm.xml" />
	</session-factory>

</hibernate-configuration>

aluno.hbm.xml

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

<hibernate-mapping>

	<class name="Aluno" table="alunos">
		<id name="alu_codigo" column="alu_codigo" type="integer" />
		<property name="alu_nome" />
	</class>

</hibernate-mapping>

GravaAluno.java (main de teste)

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;

public class GravaAluno {

	public static void main(String[] args) {

		Configuration con = new Configuration();
		con.configure("/hibernate.cfg.xml");
		SessionFactory SF = con.buildSessionFactory();
		Session session = SF.openSession();
		
		Aluno a = new Aluno();
		a.setAlu_codigo(7);
		a.setAlu_nome("Maria");
		
		Transaction tr = session.beginTransaction();
		session.save(a);
		tr.commit();
		session.close();
		SF.close();
		

	}
