Hibernate设置使用Tomcat中的连接池

1.修改Tomcat的context.xml文件

<Context reloadable="true">    <Resource name="jdbc/oracle" auth="Container"                type="javax.sql.DataSource" maxActive="100"                maxIdle="30" maxWait="10000" username="scott"                password="tiger" deiverClassName="oracle.jdbc.Oracle.Driver"                url="jdbc:oracle:thin:@localhost:1521:test"/>    <Resource name="jdbc/mysal" auth="Container"                type="javax.sql.DataSource" maxActive="100"                maxIdle="30" maxWait="10000" username="root"                password="mysqladmin" deiverClassName="com.mysql.jdbc.Driver"                url="jdbc:mysql://localhost/test"/></Context>

2.修改hibernate.cfg.xml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"><hibernate-configuration>    <session-factory><property name="connection.datasource">java:comp/env/jdbc/oracle</property>        <!-- SQL dialect -->        <property name="dialect">org.hibernate.dialect.Oracle9iDialect</property>        <!-- Enable Hibernate's current session context -->        <property name="current_session_context_class">org.hibernate.context.ManagedSessionContext</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">create</property>        <mapping resource="org/hibernate/tutorial/domain/Person.hbm.xml"/>    </session-factory></hibernate-configuration>
