1 参考 Tomcat 配置文件 配好 Tomcat 数据源

2 修改 Hibernate 配置文件

  <? xml version = '1.0' encoding = 'UTF-8' ?>

<! DOCTYPE hibernate-configuration PUBLIC

          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"         "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd" >

<!-- Generated by MyEclipse Hibernate Tools.                   -->

< hibernate-configuration >

< session-factory >

    <property name="connection.useUnicode">true</property>

    <property name="connection.characterEncoding">gb2312</property>

   <!— 只配这一句就可以了的 用户名密码等等其他参数全部不用配了的 -- >

    <property name="connection.datasource">java:comp/env/jdbc/mysql</property>

    < property name = "dialect" >

       org.hibernate.dialect.MySQLDialect

    </ property >

    < mapping resource = "com/test/Hibernate/orm/User.hbm.xml" />

</ session-factory >

</ hibernate-configuration >
