Hibernate开发备用

Hibernate开发备用

 

平时做小测试用的，稍微修改一下就可以用到正式开发环境中。

 

 

一、配置文件

<?xml version='1.0' encoding='gb2312'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        " [url]http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd[/url]">

<hibernate-configuration>

    <session-factory>

        <!--显示执行的SQL语句-->
        <property name="show_sql">true</property>
        <!--连接字符串-->
        <property name="connection.url">
            jdbc:mysql://localhost:3306/testdb
        </property>
        <!--连接数据库的用户名-->
        <property name="connection.username">root</property>
        <!--数据库用户密码-->
        <property name="connection.password">leizhimin</property>
        <!--数据库驱动-->
        <property name="connection.driver_class">
            com.mysql.jdbc.Driver
        </property>
        <!--选择使用的方言-->
        <property name="dialect">
            org.hibernate.dialect.MySQLDialect
        </property>
        <!--设置Hibernate自动管理上下文的策略-->
        <property name="current_session_context_class">thread</property>
        <!--JDBC连接池（使用内置的连接池）-->
        <property name="connection.pool_size">1</property>
        <!--是否使用数据库外连接-->
        <!--<property name="hibernate.use_outer_join">true</property>-->
        <!--事务管理类型，这里使用JDBC Transaction-->
        <property name="hiberante.transaction.factory_class">
            org.hibernate.transaction.JDBCTransactionFactory
        </property>

        <!--在启动时删除并重新创建数据库-->
        <!--<property name="hbm2ddl.auto">create</property>-->

        <mapping resource="org/lavasoft/domain/zvfims/reg/user/entity/TUser.hbm.xml"/>
        <mapping resource="org/lavasoft/domain/zvfims/reg/user/entity/TTest.hbm.xml"/>

    </session-factory>

</hibernate-configuration>

 

 

二、HibernateUtil.java

package org.lavasoft.domain.common;

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

/**
 * Created by IntelliJ IDEA.
 * User: leizhimin
 * Date: 2007-7-18
 * Time: 10:18:44
 * Hibernate工具类
 */
public class HibernateUtil {
    private static String CONFIG_FILE_LOCATION = "hibernate.cfg.xml";
    private static final ThreadLocal<Session> threadLocal = new ThreadLocal<Session>();
    private static Configuration configuration = new Configuration();
    private static SessionFactory sessionFactory;
    private static String configFile = CONFIG_FILE_LOCATION;

    static {
        try {
            configuration.configure(configFile);
            sessionFactory = configuration.buildSessionFactory();
        } catch (Exception e) {
            System.err.println("%%%% Error Creating SessionFactory %%%%");
            e.printStackTrace();
        }
    }

    private HibernateUtil() {
    }

    /**
     * Returns the ThreadLocal Session instance.  Lazy initialize
     * the <code>SessionFactory</code> if needed.
     *
     * @return Session
     * @throws HibernateException
     */
    public static Session getSession() throws HibernateException {
        Session session = (Session) threadLocal.get();

        if (session == null || !session.isOpen()) {
            if (sessionFactory == null) {
                rebuildSessionFactory();
            }
            session = (sessionFactory != null) ? sessionFactory.openSession() : null;
            threadLocal.set(session);
        }
        return session;
    }

    /**
     * 重新构建SessionFactory
     */
    public static void rebuildSessionFactory() {
        try {
            configuration.configure(configFile);
            sessionFactory = configuration.buildSessionFactory();
        } catch (Exception e) {
            System.err.println("%%%% Error Creating SessionFactory %%%%");
            e.printStackTrace();
        }
    }

    /**
     * Close the single hibernate session instance.
     *
     * @throws HibernateException
     */
    public static void closeSession() throws HibernateException {
        Session session = (Session) threadLocal.get();
        threadLocal.set(null);
        if (session != null) {
            session.close();
        }
    }

    /**
     * return session factory
     */
    public static org.hibernate.SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    /**
     * return session factory
     * <p/>
     * session factory will be rebuilded in the next call
     */
    public static void setConfigFile(String configFile) {
        HibernateUtil.configFile = configFile;
        sessionFactory = null;
    }

    /**
     * return hibernate configuration
     */
    public static Configuration getConfiguration() {
        return configuration;
    }
}
