根目录下的hibernate.properties

hibernate.dialect=org.hibernate.dialect.Oracle10gDialect
current_session_context_class=thread
hibernate.connection.url=jdbc:oracle:thin:localhost:1521:orcl
hibernate.connection.username=sj
hibernate.connection.password=123456
hibernate.connection.driver_class=oracle.jdbc.driver.OracleDriver
show_sql=true
hbm2ddl.auto=update
hibernate.connection.pool_size=1
cache.provider_class=org.hibernate.cache.NoCacheProvider

测试的Java类

package configuration;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Properties;

import hibernate.Person;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class ConfigurationTest {

	public static void main(String[] args) {		
		try {
			Properties properties = new Properties();
			File file = new File("E:/Workspace/hhh/src/hibernate.properties");
			FileInputStream stream = new FileInputStream(file);	
			properties.load(stream);
			Configuration cfg = new Configuration()
			.addClass(hibernate.DocumentType.class)
			.addClass(hibernate.Person.class)
			.setProperties(properties);
			SessionFactory sessions = cfg.buildSessionFactory();
			Session session = sessions.openSession();
			session.beginTransaction();		
			Person person = (Person)session.load(Person.class, new Long(1));
			person.getEmails().add("wow@sina.com");
			session.getTransaction().commit();
			session.close();
			System.out.println("结束");
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
