hibernate的搭建

1,  在web 项目的lib 中导入最基本 jar包：
antlr-2.7.6.jar
commons-collections-3.1.jar
dom4j-1.6.1.jar
hibernate3.jar
javassist-3.12.0.GA.jar
jta-1.1.jar
mysql-connector-java-3.1.13-bin.jar
slf4j-api-1.6.1.jar
slf4j-nop-1.6.2.jar

2.  在src目录下建立hibernate.cfg.xml配置文件，内容可以参考一下：
<?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>

<!-- Database connection settings -->
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">jdbc:mysql://localhost/hibernate</property>
<property name="connection.username">root</property>
<property name="connection.password">liuhl</property>

<!-- JDBC connection pool (use the built-in) -->
<!--  <property name="connection.pool_size">1</property>  -->

<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>

<!-- Enable Hibernate's automatic session context management -->
<!--  <property name="current_session_context_class">thread</property>  -->

<!-- Disable the second-level cache  -->
<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>

<!-- Drop and re-create the database schema on startup -->
<!-- <property name="hbm2ddl.auto">update</property>   -->

<mapping resource="com/hibernate/model/Student.hbm.xml" />

</session-factory>

</hibernate-configuration>

3.在数据库中建立student表格，然后在com.hibernate.model包下建立对应的Student类；
接着在com.hibernate.model包下建立Student.hbm.xml文件；
Student.hbm.xml文件的基本配置如：
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

<hibernate-mapping package="com.hibernate.model">
<class name="Student">
  <id name="id"></id>
  <property name="name"></property>
  <property name="age"></property>
</class>
</hibernate-mapping>

4，最后写一个测试类，如：
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

import com.hibernate.model.Student;


public class StudentTest
{

public static void main(String[] args)
{
Student s = new Student();
s.setId(1);
s.setName("张三");
s.setAge(21);

Configuration cfg = new Configuration();
SessionFactory sf = cfg.configure().buildSessionFactory();
Session session = sf.openSession();
session.beginTransaction();
session.save(s);
session.getTransaction().commit();
session.close();
sf.close();
}
}


这就是hibernate的helloworld
